The Ministry of environmental protection denies that the domestic sewage discharge standard is too low, saying that environmental protection needs to work together in many ways.

recently, some media reported that the domestic sewage discharge standard is too low, causing the sewage to pollute the surface water quality despite reaching the treatment standard. The science and technology standards Department of the Ministry of Environmental Protection said in an exclusive interview with CCTV yesterday: at present, most domestic industry standards are not low, and environmental protection standards need to work together in many ways

according to some previous reports, the discharge standards of water pollutants in China should know what you don't know so that you can better use the experimental machine. The discharge limit is far looser than the environmental quality standards for surface water, resulting in that the quality of up to standard sewage treated by many industries still exceeds that of surface water, which is inferior to class v. It is concluded that even after treatment, industrial sewage will still cause pollution. In this regard, zhaoyingmin, director of the science and Technology Standards Department of the Ministry of environmental protection, explained that in this reasoning process, there was confusion about the two concepts of industrial sewage discharge standard and water quality standard

emission standards are formulated based on the technical accessibility and economic feasibility of the industry, but environmental quality standards are more based on human health and related to environmental capacity. The standard is only one of the links in environmental management, which needs to cooperate with the pollutant discharge permit and environmental assessment. For example, the emission standards for paper mills did not take into account where they were to be built. If you are in a drinking water source, even if the enterprise can meet the discharge standard, but it will affect the drinking water safety, the environmental impact assessment will not allow it to be built

zhaoyingmin further explained that the relationship between enterprise pollution discharge and environmental quality standards should be controlled by means of total amount to ensure that the total amount of pollution discharge does not exceed the environmental capacity, so as to ensure that the local environmental quality standards. At present, the total number of environmental standards in China has exceeded 1400, and the emission standards of various industries are gradually approaching the standard level of developed countries

during the Eleventh Five Year Plan period, our national industrial emission standards will be tightened as long as they are revised. At present, many industrial standards have approached or reached the level of developed countries, so it can not be said that the current standards are still very loose. However, when there is a conflict between the brand benefits and the immediate interests of the enterprise according to the industry standards, it is impossible to discharge mineral water. Of course, our water is good, but it can not be achieved

however, zhaoyingmin also admitted that the national emission standard is the minimum threshold that industrial enterprises need to implement nationwide. For some water shortage areas or areas where the environment has been seriously polluted by the slow release of sewage capacity supply, enterprises should have higher requirements for sewage discharge

for example, Beijing is short of water, so Beijing requires that its discharge must directly meet the standard of surface water. If the river has been polluted, the environmental impact assessment should be strictly controlled

zhaoyingmin also revealed that the Ministry of environmental protection is currently revising the environmental quality standard for surface water. Now the basic consideration is that the new standard will put forward the drinking water source separately and separate the assessment of water eutrophication from the assessment of water function, that is, formulate relevant standards according to different assessment purposes
