On May 13th, the 3rd China Hazard Industry HSE High Level Seminar hosted by China Pesticide Industry Association was held in Shanghai. The seminar focused on the development of water pollution emission standards and air pollution emission standards. It is agreed that the development of the two standards will help China's pesticide industry to eliminate backward production capacity, energy conservation and emission reduction and green production. However, there are many problems in the two standards development process that need to be solved urgently. The most prominent problem is that it is difficult to achieve uniformity in the emission standards, which makes the company nervous.
Hu Linlin, deputy director of the Environmental Standards Research Institute of the Ministry of Environmental Protection, explained the main problems in the current water pollution discharge standards: the indirect emission standard limit (three-level value) is too wide, and the comprehensive wastewater discharge standard for COD (chemical oxygen demand), etc. The main indicators are too strict, the coverage of characteristic pollutants is insufficient, and the changes in the yield of pesticides are outdated. At the same time, there are the following problems in the work: First, the existing 10 standards have problems in the coverage of the pesticide industry; second, the monitoring methods are not perfect; third, no comprehensive toxicity indicators are set; fourth, emissions The standard does not apply to indirect emissions from industrial parks; fifth, the control standards for pollutants in blending and preparations are not considered. Hu Linlin said that the new standard will be open for public comment at the end of this year and will enter the administrative review process next year. It is expected to be officially implemented in 2017.
Liang Xingyin, Secretary-General of the Environmental Technology Standards Research Committee, introduced the standard framework for the emission of atmospheric pollutants from the pesticide industry, emphasizing that the purpose is to control the emission of pollutants into the atmosphere in pesticide production and reduce the emissions of particulate matter, volatile organic compounds, malodorous gases and toxic gases. Reduce the impact on haze and ambient air. It can promote the optimization of industrial structure and promote the survival of the fittest in the industry. The standard will involve air pollutants emitted from pesticide manufacturing (including raw materials , pesticide intermediates and preparation, storage and packaging). The existing enterprises will be given a two-year transition period, and new enterprises will be strictly implemented according to standards. At present, the data collection, analysis, sampling and testing emission concentration of pollutant discharge standard data are being carried out in an orderly manner. It is expected that the “Pesticide Industry Air Pollutant Emission Standard†will be announced at the end of 2014.
Air pollutant emission standards were first proposed in China's pesticide industry, and they were more concerned by representatives of participating companies. They are concerned about whether the new standards will be too high and whether existing emission treatment equipment can meet the standards. The representative said that the formulation of air pollutant standards is an inevitable trend in the development of the pesticide industry. However, there are too many uncontrollable factors in the collection of exhaust gas samples, and it is difficult to form a unified standard. At the same time, existing testing equipment and means are insufficient to cope with the new standards. Experts from the Ministry of the Environment said that the standard setting will use foreign standards as a research reference and invite most Chinese companies to participate in joint formulation. The purpose is not to restrict the development of enterprises, but to promote the healthy and sustainable development of China's pesticide industry.
