【摘要】 中国东北农村主要是以农业及畜禽养殖业为主,针对农村生活污水直接散排现象,通过建立指标体系,筛选出"膜生物反应器法(MBR)处理污水"作为推荐处理方案,通过生活污水的集中治理,污水中的COD、BOD、氨氮总氮和总磷等有机污染物质得到了有效去除,减少了污染负荷,纳污水体环境质量得到了改善。采用等标污染负荷法以及等标污染负荷比法辨识出造成杏山镇环境问题的成因与主要污染源、主要污染物,其中畜禽养殖粪便的去向以及生活污水的排放是影响环境质量的主要污染源。更多还原

【Abstract】 Rural areas in northeast China mainly focus on agriculture and livestock and poultry breeding. In view of the direct discharge of rural domestic sewage, this study proposed the "membrane bioreactor method(MBR) treatment of sewage". Through the centralized treatment of domestic sewage, the organic pollutants such as COD, BOD, ammonia nitrogen and total phosphorus in the sewage have been effectively removed. According to the investigation results of pollution sources, it identifies the causes and main pollution sources and main pollutants causing environmental problems in Xingshan Town with the equivalent pollution load method and the equivalent pollution load ratio method. The fate of livestock and poultry manure and the discharge of domestic sewage are the main sources of pollution affecting the environmental quality of the city.更多还原
