摘  要：
研究滇池流域典型城郊村镇排放污水化学需氧量(COD)和固体悬浮物(TSS)特征对于了解该类区域污水有机污染状况及治理工程设计具有指导意义。本文以主要入滇池河道——大清河下游张家庙汇水区为研究区域,通过现场采样及室内分析方法研究分析了滇池流域典型城郊村镇排放污水CODCr、TSS特征。结果表明,该区域排放污水CODCr和TSS的浓度很高,分别在773～1518mg·L-1和183～370mg·L-1之间。该区域排放污水有机污染严重。一天之中各时刻排放污水流量、CODCr、TSS浓度高峰出现在上午、中午和夜晚,低谷出现在清晨和傍晚;同一月份各天总体上差异不显著;一周内工作日与非工作日的变化差异不显著;所研究的3、4、5、6月份之间总体上差异不显著。排放污水流量和污染物CODCr、TSS浓度变化基本反映了滇池流域典型城郊村镇居民的生活方式及作息规律。

摘  要：
Chemical oxygen demand(COD) and total suspended solid(TSS) are important index in assessment of water organic pollution.A study was conducted to assess the household wastewater quality and the dynamic changes of CODCr and TSS concentrations in discharged household wastewater from typical suburb of Kunming City in Dianchi Lake Catchments.The concentrations of CODCr and TSS were analyzed and monitored regularly over the period from March through June in Zhangjiamiao village in Daqing River Catchments, which is the main river flowing into Dianchi lake.The result showed that the concentrations of CODCr and TSS in the wastewater discharged from this area were very high, ranging from 773 to 1 518 mg·L-1 and 183 to 370 mg·L-1 respectively, which indicating the severe organic pollution.The discharge flux and concentrations of CODCr and TSS in the wastewater were higher in the morning, noon and night during the day, which may be related to the daily life pattern of the local residents.However, no significant difference was found between the non-working days and the working days and the concentrations of CODCr and TSS were also no significant variations in the studied period from March through June.
