Shandong provincial capital city group to control the pollution of steel enterprises that do not meet the standards

According to the China Environmental News, the seven cities of Jinan, Zibo, Tai'an, Laiwu, Dezhou, Liaocheng and Binzhou in the provincial capital of Shandong Province closely focus on the three working mechanisms of coordinated pollution control, joint law enforcement and emergency response, from November to the following year. In the month, the cement, foundry and brick kiln industries of Jinan, Zibo, Dezhou, Liaocheng and Binzhou were all discontinued except for the production line that undertakes the task of protecting the people's livelihood; the steel industry sorted according to the level of pollution emission performance, and the implementation of the standard discharge was not stable. Discontinued; the organization issued pollution discharge permits for 7 cities of thermal power enterprises and Jinan, Zibo, Dezhou, Liaocheng, Binzhou, and cement enterprises.

“In 2016, the average concentrations of fine particulate matter (PM2.5), inhalable particulate matter (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NO2) in the urban agglomerations of Shandong Province were 75 μg/m3, 133 μg/m3 and 40 μg/m3, respectively. 43μg/m3, respectively, improved by 13.8%, 8.9%, 24.5%, 6.5%, and the number of excellent days was 47.3%, up 5.2 percentage points year-on-year." The reporter recently learned from the Shandong Provincial Environmental Protection Agency that in 2016, the provincial capital of Shandong Province The urban agglomerations of Jinan, Zibo, Tai'an, Laiwu, Dezhou, Liaocheng and Binzhou are closely related to the three working mechanisms of coordinated pollution control, joint law enforcement and emergency response, and the regional air pollution prevention and control work has achieved good results.

Regional pollution and joint governance, joint law enforcement

"Air pollution prevention and control must actively build a joint control mechanism for air pollution prevention and control, and form a regional combination of governance." This is the clear request put forward by Guo Shuqing, the governor of Shandong Province, in the investigation of air pollution prevention and control work in Jinan City in October 2016.

In order to promote regional pollution and co-governance, in accordance with the requirements of unified pollution control policies, unified governance measures, unified time limits and standards, and the preparation of the Shandong Province 2013-2020 Air Pollution Prevention and Control Plan Phase II Action Plan (2016~2017), The 7 cities of Shandong provincial capital city group highlighted key areas such as structural adjustment, point source management, non-point source control, and capacity building, and refined 35 categories of 1820 key projects to ensure completion within two years and promote continuous improvement of atmospheric environmental quality.

Focusing on accelerating the pollution control of key industries, Shandong Province will clarify the transformation tasks one by one to enterprises, to unit facilities, to specific months, and decompose at different levels to ensure implementation. As of the end of last year, the 7 cities of the provincial capital city group have completed the ultra-low emission transformation of 114 total installed coal-fired units of 35.665 million kilowatts, with a completion rate of 91%; the five cities of Jinan, Zibo, Dezhou, Liaocheng and Binzhou have a total area of ​​1164m2 sintering machine, total The volume of 4250m3 blast furnace was upgraded. It has completed the transformation of 7 sets of 1044m2 sintering machine and 6 sets of total volume 3745m3 blast furnace.

In terms of seasonal production regulation, Jinan, Zibo, Dezhou, Liaocheng and Binzhou have formulated seasonal production of electric power and other key industries in accordance with the requirements of the National “Beijing-Tianjin-Hebei Intensive Measures for Prevention and Control of Atmospheric Pollution (2016~2017)”. The implementation plan of the control measures, and clarified the list of regulated enterprises, and reduced pollution emissions through measures such as limiting production, suspending production, and changing fire. The five cities of Jinan, Zibo, Dezhou, Liaocheng and Binzhou timely launched the online monitoring equipment installation work of the elevated source enterprises. 342 high-end source enterprises in 5 cities have installed 644 automatic monitoring equipments, with an installation rate of 100%; 644 connected networks, networked The rate is 100%.

In 2016, the Environmental Protection Department of Shandong Province organized two joint action actions on air pollution enforcement in the provincial capitals, and a total of 545 environmental law enforcement personnel were dispatched (times) to inspect more than 150 key pollutant discharge units (times) and urged 231 environmental protection issues to be highlighted. Seven cases of environmental violations were investigated and punished. In order to ensure the effectiveness of the joint law enforcement, the post-inspection of the implementation of the rectification of the provincial capital city group 7 was carried out, and the issue of non-implementation of rectification found in the inspector was publicly notified and exposed, forcing the enterprise to consciously perform its duties and actively rectify.

Highlight four major aspects and identify 17 measures

In order to build the provincial capital city into a province's transformation and upgrading demonstration zone and ecological civilization harmonious zone, Shandong has specially issued the "Implementation Plan for Further Strengthening the Prevention and Control of Air Pollution in the Capital Cities of the Province" (hereinafter referred to as the "Program"), highlighting the structural adjustment of the energy industry. In the four major aspects of industrial pollution control, dust pollution remediation, and motor vehicle pollution prevention and control, 17 measures were proposed.

“The air quality of the provincial capitals of Jinan, Zibo, Tai'an, Laiwu, Dezhou, Liaocheng and Binzhou continued to improve. By 2017, the regional ambient air quality improved by about 35% compared with 2013; Jinan, Zibo, Tai'an, Laiwu, Dezhou, The average annual concentration of fine particulate matter (PM2.5) in Liaocheng and Binzhou 7 cities reached 70 μg/m3, 74 μg/m3, 59 μg/m3, 67 μg/m3, 85 μg/m3, and 85 μg. / cubic meters, 65 micrograms / cubic meter. By 2020, the ambient air quality of the provincial capital group area is improved by about 50% compared with 2013. This is the goal proposed in the "Program".

In terms of in-depth promotion of energy and industrial restructuring, in 2017, the 7 cities strived to complete the provincial government's total coal consumption control target task ahead of schedule, basically establishing a city and county coal emergency reserve distribution system and a clean coal supply network covering towns and villages. By 2020, the main city of 7 cities will basically achieve no coal.

In the comprehensive management of industrial pollution, the seven cities should organize key projects such as coking and coking kiln to complete the upgrading of sulfur dioxide treatment facilities. From November to January of each year, the cement, foundry and brick kiln industries of Jinan, Zibo, Dezhou, Liaocheng and Binzhou are all in addition to the production lines for residents' heating and co-processing of urban garbage and hazardous waste. Discontinued; for coal-fired generating units (including self-supplied power plants) that do not meet the ultra-low emission standard limits, except for the units that undertake the heating tasks of the residents, all of them are discontinued; the industry ranks according to the level of pollution emission performance, and the implementation of stable discharge standards cannot be achieved. Discontinued; the glass industry produces fuels that are all replaced with natural gas, concentrated supply of coal-based natural gas or electricity and other clean energy.

In the comprehensive improvement of dust pollution, 7 cities should incorporate construction dust pollution control into the credit management system of construction enterprises, and establish a linkage mechanism between dust pollution prevention and construction market integrity. Before the end of June 2017, the open-pit mining mines in the urban-rural junction will be completely closed.

In terms of motor vehicle pollution prevention and control, from July 1, 2017, all the ordinary diesel fuel supplied by the 7 city gas stations have reached the national IV standard; from January 1, 2018, the ordinary diesel fuel supplied by the gas stations all reached the national V. standard.

Implement joint prevention and control, clear protection system

Shandong Province requires that it strengthen organizational leadership, improve policy support, and further improve the joint control mechanism for air pollution prevention and control in provincial capitals.

In accordance with the idea of ​​“regular consultation, responsibility sharing, linkage law enforcement, and joint prevention and treatment”, the seven cities will improve and improve the coordination and pollution control, joint law enforcement, and emergency response work mechanisms. Deepen the mechanism of coordinated pollution control, coordinate pollution pollution control, comprehensively strengthen the joint law enforcement mechanism, carry out cross-examination and law enforcement linkage in administrative border areas, and gradually expand the scope of inspection from industrial pollution control to oil quality supervision and control. The fields of motor vehicle exhaust control and straw burning; deepen the emergency linkage mechanism, implement regional air quality forecast and warning information sharing, unify early warning and grading, and unified response measures.

In addition, we must take the lead in establishing a three-level environmental supervision grid at the city, county, and township levels, and gradually extend to the village level. It is necessary to strengthen the supervision of pollutant discharge permits, and organize the issuance of pollutant discharge permits for 7 cities of thermal power enterprises and Jinan, Zibo, Dezhou, Liaocheng, Binzhou, and cement enterprises. Strictly elevated source environmental management is required. The emission chimneys of all elevated source enterprises in Jinan, Zibo, Dezhou, Liaocheng and Binzhou are installed online monitoring and four-level networking, and the emission information is open to the public and accepts social supervision. It is necessary to improve and improve the emergency response plan system, unify the level of early warning and response, and unify emergency measures.

It is understood that the Shandong Provincial Government will incorporate the prevention and control of air pollution into the important content of provincial environmental protection inspectors, and conduct early warning notifications, regional restrictions and administrative interviews on work progress and environmental quality for a long time without effective improvement. Ineffectiveness and lack of performance lead to serious accountability for outstanding missions and air quality improvement goals.

Difference Between CNC Milling and CNC Turning
CNC Milling and CNC Turning allow users to create patterns and add detail to metals that are impossible to do by hand. CNC Milling uses commands, codes programmed into the computer and set to run. The mill then drills and turns along axes to cut materials to dimensions entered into the computer. Computer programming allows machines to make precise cuts, users can manually override the CNC Machines to slow or speed up the process.
In contrast, CNC Turning uses computer-controlled machines to create a different final product. The process uses a single-point cutting tool that inserts parallel to the material to cut. The material is rotated at changing speeds and the tool cutting traverses to create cylindrical cuts with exact measurements. It is used to create circular or tubular shares from larger material pieces. It is an automated process and speeds can be adjustments for greater accuracy rather than turning a lathe by hand.
What parts need CNC Turning?
There is no question that CNC Milling and CNC Turning are very different processes that will in most cases end up with entirely different results. CNC Centres are ideal for short-run volumes and especially prototypes and parts that are below 2.5" while the turning centre can be able to work on parts that are over the 2.5" OD, they will need to be checked individually and depending on the volume of the parts that are being produced, it can have an upward impact on the price of production. Also, if the part is less than 1.25" OD, turning might not be the option for producing that part. However, it is important to note that the biggest factor that determines if the piece can be produced by CNC Turning is the volume. The higher the volume the less suitable the part is suitable to be produced by turning.
