皖西地区小城镇污水处理适用工艺技术探讨

皖西地区小城镇污水排放具有水量小、水量水质变化大、污水收集困难等特点,根据污水处理的低建设运行成本、低运行管理及技术要求、高的污染物去除率及稳定性等要求,皖西小城镇污水治理的建设标准、排放标准、投资运行费用及处理工艺选择等宜合理选择制定。皖西小城镇污水治理应因地制宜地选择接触氧化、滴滤池、氧化沟、生态塘及人工湿地等工艺技术。

Discussion on Domestic Wastewater Treatment Technology Applicable for Rural Towns in West Anhui Region

In small towns of West Anhui,The sewage dischargment is low, sewage quality change is large, sewage collection is diffi- cult. According to the request of low-cost, low operating management and technical requirements, high removal rate of pollutants and high stability,this paper discusses the construction standards, emission standards,investment and running costs of treatment process and the selection of sewage treatment technology. And according to local condition, Contact Oxidation, Trickling Filter, Ox- idation Ditch,Ecological Pond and Constructed Wetlands could be choosed in small towns of West Anhui.
