In order to promote the continuous improvement of air quality in key areas, in the first half of March, the Ministry of Ecology and Environment sent 14 professional groups to focus on key areas such as Beijing-Tianjin-Hebei and surrounding areas, and carried out in-depth supervision and assistance for air quality improvement. With the support and cooperation of the local government and relevant departments, a number of outstanding gas-related environmental problems have been discovered.
In order to give full play to the warning function, the Ministry of Ecology and Environment disclosed the typical problems of seven enterprises on April 19, 2022, including Cangzhou Hebei Jintai Glass Fiber Products Co., Ltd., Hengshui Anping Xinze Stainless Steel Products Co., Ltd., Liaoning Fuxin Hongshun Machinery Co., Ltd., Jinzhou Jinzhou Heavy-duty Water Pump Co., Ltd., Shandong Taian Feicheng Changsheng Special Graphite Co., Ltd., Liaocheng chiping Magnesium Technology Co., Ltd. and Xinxiang fengqiu county Xinda Leather Co., Ltd.
1. Cangzhou Hebei Jintai Glass Fiber Products Co., Ltd. failed to build pollution control facilities as required.
Hebei Jintai Glass Fiber Products Co., Ltd. is located in Beixinzhuang Township, Renqiu City, Cangzhou City, mainly engaged in the manufacture of glass fiber and products. According to the requirements of the pollution discharge permit, the furnace waste gas is discharged after denitrification by SCR (selective catalytic reduction method). The inspection of the working group found that during the normal production of the company, SCR denitration facilities were not built in the furnace process as required, and the exhaust gas was directly discharged without denitration treatment, which polluted the atmospheric environment.
Second, Hengshui Anping Xinze Stainless Steel Products Co., Ltd. discharges atmospheric pollutants through bypass.
Anping Xinze Stainless Steel Products Co., Ltd. is located in Nanwangzhuang Town, Anping County, Hengshui City, Hebei Province, mainly engaged in stainless steel pipe fittings production. According to the requirements of EIA document and reply, the waste gas generated from dewaxing process is collected and discharged through activated carbon adsorption device. The working group found that the dewaxing process of the company was running, and some waste gas did not enter the treatment facilities, but was directly discharged through the direct pipeline (bypass) in front of the treatment facilities, polluting the atmospheric environment.
3. Fuxin Hongshun Machinery Co., Ltd. failed to install and operate pollution control facilities as required.
Fuxin Hongshun Machinery Co., Ltd. is located in Fuxin Economic Development Zone, Liaoning Province, mainly engaged in ferrous metal casting. According to the requirements of EIA documents and pollution discharge permit, the waste gas containing dust and VOCs generated in the casting section is discharged after being treated by bag dust collector and activated carbon+plasma purification device. The working group found that the casting section of the company was producing, but the waste gas treatment facilities were not installed as required, and a large amount of flue gas was discharged directly without treatment, which polluted the atmospheric environment.
At the same time, it is also found that the sand treatment and core-making molding sections are being produced, but the dust collection pipeline is not connected with the dust removal equipment, and the supporting bag dust collector is not running.
4. Jinzhou Jinzhou Heavy Water Pump Co., Ltd. failed to install pollution control facilities as required.
Jinzhou Heavy-duty Water Pump Co., Ltd. is located in Qilihe Industrial Park, Jinzhou City, Liaoning Province, and is mainly engaged in the manufacture of water pumps and vacuum equipment. According to the approval requirements of environmental impact assessment, the particles produced in the smelting, core-making, molding/pouring processes of small foundry workshops are collected by gas collectors and discharged after being treated by bag dust collectors. The inspection of the working group found that the company was carrying out molding/pouring operations outdoors, and the exhaust gas was directly discharged without collection and treatment, which polluted the atmospheric environment.
Five, Taian Feicheng Changsheng Special Graphite Co., Ltd. abnormal operation of automatic monitoring equipment for pollution sources
Feicheng Changsheng Special Graphite Co., Ltd. is located in Shiheng Town, Feicheng City, Tai ‘an City, Shandong Province. It is mainly engaged in the production of graphite and carbon products, and is a key pollutant discharge unit of atmospheric environment in Tai ‘an City. According to the requirements of the pollution discharge permit, the waste gas from the calciner is discharged through the 3# flue gas discharge port (No.DA010) equipped with automatic monitoring equipment for pollution sources. The inspection of the working group found that at 18: 00 on February 1, 2022, the company shut down the automatic monitoring equipment and video monitoring without authorization when there was still exhaust gas from the roaster, which made it impossible to effectively monitor and monitor the exhaust gas discharged in some time periods from February 1 to 7, violating the relevant provisions of Article 24 of the Air Pollution Prevention Law that key pollutant discharge units should ensure the normal use of automatic monitoring equipment for air pollutant discharge.
6. Liaocheng chiping Meiji Technology Co., Ltd. does not operate pollution prevention facilities normally.
Chiping Meiji Technology Co., Ltd. is located in Xinfa Street, Chiping District, Liaocheng City, Shandong Province, mainly engaged in the production and processing of desulfurization gypsum and Jiayi powder. On-site inspection found that the company’s selected drying gypsum production line was in production, but the supporting spray dust removal tower and RTO system (regenerative thermal oxidation furnace) were damaged and could not be used normally, and the exhaust gas was discharged without effective treatment, polluting the atmospheric environment.
The inspection also found that the waste gas pipeline and fan in the dissolution and purification section of the company were damaged, and the unorganized emission of waste gas in the workshop was serious.
7. Xinxiang fengqiu county Xinda Leather Co., Ltd. failed to install pollution control facilities as required.
Fengqiu county Xinda Leather Co., Ltd. is located in Hui Township Industrial Zone, Jingxiang Township, fengqiu county City, Xinxiang City, Henan Province, with an annual processing capacity of 1.5 million wet blue sheepskins. According to the requirements of pollutant discharge permit and EIA document, unorganized waste gas from sewage treatment tank should be collected in a centralized way, and then treated by spray absorption and strong oxidation technology; Raw hide Warehouse needs to build a closed storage warehouse, and it should be equipped with two deodorizing and spraying equipment. The inspection of the working group found that the company was in normal production, the waste gas treatment facilities were not built as required in the sewage treatment tank, and the raw hide storage was not equipped with deodorization spraying equipment, resulting in unorganized emission of waste gas, which polluted the atmospheric environment. The local ecological environment department has filed a case for investigation.
