摘要
通过对渝东北地区10个区县210余座乡镇生活污水处理厂的实地调查研究,发现乡镇生活污水处理工艺具有多样性,主要为生物转盘、人工快渗、膜生物反应器以及梯田式多级人工湿地等。污水处理厂处理规模普遍较小,73%以上的设计处理规模在1000 m^3/d及以下,且部分污水处理厂设计处理规模远大于实际处理规模;其污染物排放标准大多援引城镇污水处理厂污染物排放标准;同时,污水处理厂运行管理方面也存在着不同程度的问题。根据这些现状调查、分析及思考,对乡镇生活污水处理的发展提出了相应的发展对策。
We investigated 210 township domestic sewage treatment plants in 10 districts and counties of northeastern Chongqing,the results showed that the treatment process of township domestic sewage had diversity.The main methods were biological rotary table,artificial rapid infiltration,membrane bioreactor,terraced multi-stage constructed wetland and so on.In addition,the treatment scale of sewage treatment plant was generally small,and more than 73%of the designed treatment scale was less than 1000 m^3/d,and the treatment scale of some sewage treatment plants was much larger than that of the actual treatment scale.Furthermore,most of its pollutant discharge standards refer to the pollutant discharge standards of municipal sewage treatment plants.At the same time,there were also some problems in operation and management.Based on the investigation,analysis and consideration of the present situation,this paper put forward the corresponding development countermeasures for the development of domestic sewage treatment in villages and towns.
