| 摘 要： | 对以生污泥法为主体的城市污水二级处理过程进行了包括达标排放、微污染和急性毒性指标在内的效果评价。指出以常规指标判断；二级活性污泥法处理出水满足国家达标排放的要求，但是处理过程对有机微污染和急性毒性的去除效果却十分有限。

| Abstract: | The efficiencies of municipal wastewater treatment processes are evaluated in terms of a group of collective parameters, composition and concentration variation of micropollutants, as well as changes in acute toxicity. While the outflow of the secondary treatment based on active sludge technology can meet satisfactorily the National Integrated Wastewater Discharge Standard, but a limited removal of persistent organic pollutants and acute toxicity can be expected. |
