265 hardware enterprises in Zhejiang Yongkang comprehensively rectified

Jinhua Yongkang City carried out a “review” special action for the hardware coating enterprises, and carried out a comprehensive evaluation of the enterprises that had been rectified. Up to now, the city's 655 metal painting companies have completely completed the rectification. Yongkang is the famous “China Hardware Capital”. The regional economy is dominated by the hardware industry. The painting process is a necessary production link for some hardware products. It involves VOCs (volatile organic compounds) emissions and affects the local atmospheric environment. Quality factor. Last year, the Central Environmental Protection Inspector Group pointed out that among the 655 hardware painting enterprises in Yongkang, 300 of them did not have exhaust gas treatment facilities, and the masses reflected more.
Yongkang took the opportunity of the central environmental protection inspector to organize the rectification of the VOCs of the hardware coating enterprises, established a list of pollution sources through the census, formulated the industry rectification norms and technical guidelines, and promoted the rectification of the hardware coating industry. “Mechanical Waste Gas Treatment in the Finishing Industry” became one of the top ten livelihoods of the Yongkang government in 2018.
With the advancement of remediation, business owners are no longer strangers to VOCs. The local government provides technical support by approaching the company by sending technology and sending services. Since the beginning of this year, the environmental protection department of Yongkang City has taken the lead. All towns (streets and districts) regularly hold training sessions on VOCs pollution remediation in the hardware coating industry, invite industry experts to provide technical guidance, and build a technical communication platform for VOCs to control enterprises and environmental enterprises. Up to now, the Municipal Environmental Protection Bureau has arranged technical backbones to conduct 15 trainings on VOCs remediation services in various towns (streets and districts). Runlong Industry and Trade is a local non-standard door enterprise. As early as this year, before the company was put into production, it first introduced a set of exhaust gas treatment equipment to increase the rectification of VOCs. Shu Youyi, head of the company, said: "We have invested more than 800,000 yuan in environmental protection facilities, and we have to invest in a number of waste gas treatment facilities in the later period."
In addition, Yongkang also hired experts from Zhejiang Academy of Environmental Sciences and Jinhua City Academy of Science and Technology as the “think tank” for the renovation of Yongkang hardware coating industry, and successively issued the “Regulations on the Renovation of Hardware Coating Industry in Yongkang City”. "The Best Feasibility Technical Guide for VOCs Pollution Prevention and Control in the Hardware Coating Industry of Yongkang City", through the best feasibility technology in the replacement of raw materials, production technology and management, and improvement of production equipment level, to reduce emission reduction for enterprise VOCs Provide technical support to accelerate the transformation and upgrading of the hardware coating industry.
Pollution prevention and control initiated by source management has played a key role in reducing emissions. With the help of the environmental protection department, the Stepang Group has independently researched and developed the company to replace the paint with modified all-resin powder coatings, and to reduce the emission of VOCs by enterprises through source control. After the transformation, compared with the original process, it can reduce 240 tons of VOCs, 160 tons of hazardous waste and 600,000 yuan of equipment electricity. At present, Yongkang has more than 50 enterprises in the three major hardware industries of the pot industry, door industry and cup industry through water-soluble paint, all-resin powder coating, low-volatility solvent and other improved technologies. The VOCs source has significant emission reduction effects.
For the rectification of whether the standard is up to standard, Yongkang has also set a strict appraisal threshold. According to the requirements, after the rectification enterprise installs the exhaust gas treatment facilities, it must also carry out the exhaust gas detection, and the completion of the record can be completed. For enterprises that do not cooperate with rectification and have not completed rectification within the time limit, they will take compulsory power cut measures to stop production and rectification. After the rectification, it is necessary to conduct a comprehensive "review" inspection, and conduct a comprehensive performance evaluation of the completion of the rectification to ensure that the company's high-quality, strict standards to complete the rectification and rectification tasks.
