| 摘 要： | 针对兼性生化低温状态去除效果差、污泥易流失等问题,提出采取物化兼性生化联用法来提高其处理效果.并采用对比法研究物化、兼性生化及二者联用技术处理低温城市污水.研究结果表明在聚合氯化铝（PAC）投加量为20mg/L时,物化与兼性生化在COD、浊度及TP的去除方面表现出良好的协同作用,但脱氮效果一般;二者协同作用能以较小的投药量有效改善低温状态兼性生化处理效果及污泥流失现象,为后续生态单元的稳定运行提供了保障.

| Abstract: | Facultative biodegradation integrating physicochemical process was proposed to improve the pollutant removal efficiencies, contraposing the low removal efficiencies of pollutants in wastewater and sludge easily washing-out. The results of the researches showed that, when the dosage of PAC was 20mg/L, facultative biodegradation-physicochemical process expressed better synergistic action in respect of removals of COD, turbidity and TP, while its effect on nitrogen removal was not very obvious. The both's synergistic action could effectively improve facultative biochemical treatment effect at low temperature and sludge washing-out, providing guaranty for stable operation of following-up ecological units. |
