摘　　要：研究了钱塘江沿岸杭州市主要污水处理厂进水和出水水体中TOC以及COD的关联性。选取13家污水处理厂进水和出水进行取样,分别测定TOC以及COD,结果显示这13家污水厂64%的COD与TOC比值落在1.2~5.75;36%的COD与TOC比值落在6.21~36.5。其中工业园区型污水处理厂的COD与TOC比值明显比城镇型污水处理厂要低。The relationship between TOC and COD in influent and effluent water of Hangzhou main wastewater treatment plants along the riversides of Qiantang River was studied.Thirteen samples from the influent and effluent of these sewage treatment plants were selected,and TOC and COD were measured.The results showed that COD and TOC ratio of 64 percent of the sewage treatment plants were between 1.2~5.75.The rest of them were in 6.21-36.5.Among them,the ratio of COD to TOC in Industrifil Park sewage treatment plant was obviously lower than that in town sewage treatment plant.
