“集中处理”不能变成“集中排污”，工业园区污水处理酿新规

Core Points - The article highlights the need for new pollution discharge standards for wastewater treatment facilities in industrial parks to mitigate environmental risks and protect aquatic ecosystems and public health [1][4][5] - The Ministry of Ecology and Environment is currently soliciting public opinions on the draft technical guidelines for establishing these new discharge standards [1][4] Group 1: Current Situation - There are currently 2,962 industrial parks across 31 provinces and regions in China, with nearly 600 being chemical parks [2] - Industrial parks typically handle wastewater from various sources, including production wastewater from enterprises, domestic sewage, and wastewater from port operations [2][4] - The wastewater characteristics vary significantly among different types of industrial parks, such as single-industry parks and comprehensive parks [2][4] Group 2: Issues Identified - Existing discharge standards for industrial parks are often inadequate, with incomplete pollution control projects leading to high environmental risk [1][4] - The wastewater quality from industrial parks differs significantly from municipal sewage, necessitating tailored discharge standards [1][4][6] Group 3: Proposed Regulations - The draft guidelines propose comprehensive pollution control measures, considering various pollutants and their characteristics based on incoming water quality [4][5] - The new standards will allow for differentiated discharge limits based on the environmental quality requirements of receiving water bodies [5][6] - The regulations aim to ease the burden on enterprises by allowing negotiated indirect discharge limits, reducing the need for additional wastewater treatment facilities [5][6]
