Jiangsu Chemical Park recovery dilemma: environmental supervision capacity is insufficient waste safety is difficult to measure.

more than 8 months after the "3-21" special major explosion accident, sub-north Chemical Park is still in a depression, not only because the local government in the accident investigation report before the out of the action, but also some of the chemical park "in the table" impact.f3W
data show that the existing chemical production enterprises in Jiangsu only about 30% of the parking rate, some areas even only 10%;Tian Jinping, an associate researcher at the School of Environmental
off3W , said that chemical companies usually have a good understanding of the safety of raw materials, intermediates, products and chemical reactions, but they have a good understanding of the safety of waste, especially solid waste, because of its complex composition and their safety.f3W
"Daily Economic News" reporter from the Greenstone Environmental Protection Center published a Jiangsu Chemical Park environmental research report learned that from June 2018 to October 2019, 44 chemical park in Jiangsu Province, water and gas slag regulatory focus is very different. Only 70% of enterprises do not see the obvious black odorwater and odorous gas, 48% of enterprises do not achieve rain pollution diversion, and rain drains rely on manual testing and management, 36% of enterprises do not have atmospheric monitoring stations and only key enterprises have probes.f3Wadjustment report is of great significance to the guidance of chemical enterprises f3W
According to Xinhua News Agency on November 15, the State Council approved the "3-21" special major explosion investigation report of Jiangsu Zhongshui Tian Jiayi Chemical Co., Ltd. (hereinafter referred to as Tian Jiayi Company). The investigation team of the State Council determined that the accident was a special major production safety liability accident caused by spontaneous combustion caused by the long-term illegal storage of hazardous waste.f3W
november 20, Jiangsu Provincial Committee, provincial government held the "3-21" special major explosion warning education conference. Jiangsu Provincial Party Secretary Zhai Qinjian pointed out that the warning of this accident as a turning point, to promote the safety of production and governance system and governance capacity modernization in the forefront.f3W
the Daily Economic News reporter noted that the investigation report shows that the accident is the direct cause of Tian Jiayi company's old solid waste warehouse long-term illegal storage of nitrification waste, continuous heat heating caused by spontaneous combustion, combustion caused by explosion. It is reported that the nitrification waste has the characteristics of self-decomposition, the decomposition of heat, and decomposition rate with the temperature increases and accelerates.f3W
experimental data show that under insulation conditions, the longer the storage time of nitrification waste, the more likely it is to spontaneous combustion. The maximum storage time for nitrification waste stored in Tian Jiayi's old solid waste warehouse is more than 7 years.f3W
report notes show: "Through thermal safety analysis experiments and theoretical calculations, it can be seen that under thermal conditions, the starting temperature of nitrification waste is 39.2 degrees C, due to self-liberation heat, storage after 1 year the temperature will rise to the point of spontaneous combustion, spontaneous combustion; Self-ignition occurs after 3 years when the starting temperature of the chemical waste is 26.8 degrees C, after 5 years when the starting temperature of the nitrification waste is 21.1 degrees C, and after 7 years when the starting temperature of the chemical waste is 17.3 degrees C.f3W
, Tian Said, said the case shows that the resulting nitrosise waste can spontaneously ignite even at lower temperatures. This reminds chemical enterprises, solid waste treatment, disposal process to strengthen the nature of materials / waste to a fuller and more comprehensive understanding.f3W " here reflects the use of thermal safety analysis in the process of investigation and determination of thermal safety experimental science, quantitative understanding of the nature of the material, in fact, this method for chemical enterprises research and development, design, production, management in troubleshooting, prevention of safety hazards has a very large guiding significance. Tian Jinping said.f3Wchemical enterprises are still in a state of stoppagef3W
starting in 2018, some chemical park enterprises in Jiangsu began to stop production and rectification. According to CCTV reports in April 2018, Lianyungang City, the lin-port industrial park in the chemical enterprises there is environmental pollution problems, Lianyungang Municipal Government immediately began environmental protection work, until the end of 2018, some enterprises have passed the acceptance and resume production.f3W
and since the explosion in Tianjiayi in March this year, the application for the resumption of production of the chemical company in northern Jiangsu has been delayed. As of November 15, the website of the People's Government of Dafeng District of Yancheng City announced that the application for resumption of production of five chemical enterprises in the area had passed the first instance and district-level acceptance of the port area, and that it was intended to apply for municipal review. Among them, Huifeng shares (002496, SZ) ten products to resume production applications through the port area of the first instance, district-level acceptance.f3W
November 27, Dafeng District, the relevant staff to the "Daily Economic News" reporter revealed that the relevant enterprises did announce the resumption of production applications, but at present only Fengshan Group (603810, SH) in Dafeng District has officially started production, other chemical enterprises have not resumed production.f3W
According to Fengshan Group's Announcement on October 21, the company from April 18 to the original pharmaceutical synthesis workshop for temporary shutdown, September 18, the company's resumption of production application passed the port area of the first instance, district-level acceptance; On October 21st, the Government of Yancheng Dafeng District agreed in principle to resume production of Fengshan Group, the heating company plans to resume heating at 12 pm on October 25, and the company's original pharmaceutical synthesis workshop is expected to resume production on October 25. In addition, on November 14, Fengshan Group withdrew other risk warnings, "ST" hat removal success.f3W
financial data show that Fengshan Group's operating income in the first three quarters of this year was 729 million yuan, down 27.84 percent year-on-year, and attributable net profit was 47.75 million yuan, down 49.73 percent year-on-year, almost a waist-down. f3W
on November 27, the Daily Economic News reporter called Fengshan Group and Huifeng Shares to inquire about the resumption of production, but did not respond. It is understood that the two companies are in Dafeng District, previously said that because the local park central heating company on the entire line of the steam network safety monitoring, maintenance, stop external heating, so decided to temporarily stop production. f3W
now That Fengshan Group has resumed production, and The application for a resumption of Huifeng shares has not yet been heard. According to The China Chemical News, on August 26, the Salt City Chemical Industry Safety and Environmental Protection Promotion Leading Group Office issued the "Salt City Stop production and rectification chemical production enterprises re-production workflow", causing many local enterprises to complain and question. f3W
documents show that not only the enterprise does not have the right to resume production on its own, but also through the chemical park where the enterprise is located, the county people's government or related departments, the municipal government and the municipal administration and other departments signed, accepted, reviewed, in order to produce. In addition, the document also attached some special provisions, the municipal review of the county (city, district) not approved by the municipal government, within 3 months from the date of written approval, the county (city, district) may not submit a new application for resumption of production; f3W
chemical park environmental supervision is weak f3W
in the sound water "3.21" special major explosion warning education conference, Jiangsu Provincial Party Secretary Zhai Qinjian pointed out that chemical industry is the basic industry of the national economy, but also a pillar industry in Jiangsu Province, to adhere to the "essential safety, green high-end", through "smashing cage snare for green", "cage for birds", "cage for birds", "cage-for-cage" f3W
Xinhua reported that on April 4, the Salt City Standing Committee held a meeting to say that the Ringwater Chemical Park would be completely closed. The investigation report of the accident also revealed that the environmental protection department did not seriously perform their duties, law enforcement and other issues. f3W
According to a Jiangsu Chemical Park Environmental Research Report published by the Greenstone Environmental Protection Center, from June 2018 to October 2019, only 70% of the 44 chemical parks in Jiangsu Province did not see obvious black odor water and odorous gases; f3W
Tianjin Teda Low-Carbon Economic Promotion Center National Economic And Technological Development Zone Green Development Alliance Secretariat Zhang Haoxiang said that the green development of the chemical park is outstanding. Among them, the safety capacity of the park is difficult to calculate effectively, the chemical park as a special chemical enterprise gathering area, it is necessary to control the total amount of hazardous substances in the park, the calculation method and scope of the safety capacity of the park has not formed a unified opinion, the safety capacity of the park has not yet formed a guiding technical index. f3W
, in addition, some chemical park admission standards are low, blind introduction. In order to achieve economic development, some parks in the introduction of enterprises there is a rush to achieve the psychology, some parks ignore the technical content of the project, at the expense of the environment, some serious pollution, overcapacity, backward technology projects into the park, for the sustainable development of the park left hidden dangers. Zhang Haoxiang,
of the f3W , said that the environmental protection of industrial parks has a basic framework, one is based on the "three lines, one single" strict environmental access, the other is that industrial park enterprises and institutions do not have serious pollution environmental events, no major, major environmental emergencies, three is the industrial park key pollution source stable emission standards, four is to achieve the total amount of pollutant emissions control of industrial parks enterprises and institutions, five is the industrial park has a sound environmental risk management system and environmental emergency protection measures. f3W
Zhang Haoxiang suggested that, from the park's point of view, to serve the green development requirements, while serving the park development, out of the traditional thinking, to avoid headaches, feet pain, out of their own business limitations thinking, to establish comprehensive solution capacity, out of simple hardware construction thinking, to establish a combination of planning, consulting management planning system. f3W .
