摘　　要：　在城市污水生物絮凝强化一级处理的基础上,通过投加高效微生物絮凝剂产生菌强化生物絮凝作用,以提高强化一级处理出水水质.首先采用静态正交实验确定强化一级处理工艺的优化运行参数,然后通过两个动态实验(普通工艺和投菌工艺)的对比,证实了投加高效絮凝剂产生菌M-25能促进天然絮凝物质的产生,强化生物絮凝吸附作用,使污水COD、SCOD和SS的去除率分别达到63.7%,35.2%和74.2%,比普通工艺分别提高9.2%,7.2%和12.6%,有利于减少城市污水污染物的排放总量,减轻对自然水体的污染.Based on Bioflocculation intensified primary treatment of municipal wastewater, an experiment has been done, in which a high efficiency microbial flocculant strain (M-25) was added, and the quality of owtcet water was improved.Through a static orthogonal experiment, the operating parameters of the technology were defined, then, two dynamic experiments, the general technology and the strain-adding technology, were contrasted. The results indicated that the removal ratio of COD, SCOD and SS of the strain-adding technology reached 63.1%, 35.2% and 74.2%, improved by 9.2%, 7.2% and 12.6% respectively contrasting to the conventional technology. So the strain-adding technology can visibly contributed to decreasing the total pollutant in the municipal wastewater discharged to natural water.
