摘要
以中部地区典型县域17座乡镇污水处理厂为例,对乡镇污水排放的现状进行调研分析,详细介绍了乡镇污水水量水质特点以及与设计值之间的差异。为进一步分析水质,选择设计处理水量最大的T镇和最小的G城、以及年均负荷率最高的A镇和最低的HT镇进行数据收集和分析。乡镇污水主要的污染物COD、总氮、氨氮和总磷的月均值浓度范围分别为74.2~230.8mg/L、23.2~32.6mg/L、19.1~27.0mg/L、2.2~3.7mg/L。基于上述17座污水处理厂实际运营数据,验证水量设计计算取值的合理性,为中部地区乡镇污水处理设计进水各污染物浓度限值提供了工程依据,同时也有助于后续运营管理。
The 17 Sewage Treatment plants in China typical villages were investigated and analyzed,including the designed influent and effluent quality and capacity,the present influent and effluent quality and capacity and the annual load rate.In order to further analyze the water quality,T Town and G Town with the largest designed water treatment capacity,A Town with the highest annual load rate and HT Town with the lowest annual load rate were selected for data collection and analysis.The monthly mean concentration range of the main pollutants COD,total nitrogen,ammonia nitrogen and total phosphorus in village and town sewage is 74.2~230.8mg/L,23.2~32.6mg/L,19.1~27.0mg/L and 2.2~3.7mg/L,respectively.Based on the actual operation data of the 17 sewage treatment plants mentioned above,the rationality of the water volume design calculation method is verified,and the engineering basis is provided for the design of the influent pollutant concentration limits of the township sewage treatment plants in the central region.
