新疆克孜勒苏河喀什市段入河污染物估算及特征分析

依据污染源调查资料,采用距离法对克孜勒苏河喀什市段污染物的入河量进行估算。结果表明:污水处理厂排放口是克孜勒苏河喀什市段最主要的污染源,COD、NH3-N、TN、TP的排放量占研究区域总量的61%~83%;其次是豆腐厂总排口,4项指标占研究区域总排放量的17%~37%,也是该河段的主要污染源。两者各指标排放量之和均超过区域总量的98%。不同类型的污染源中,生活源COD、NH3-N、TN、TP的贡献率分别是工业源的2、5、4和1.6倍。

Estimation and Characteristic Analysis of Pollutants in the Xinjiang Kezilesu River in Kashi City

According to the pollution source census data, estimate the total amount of Pollutants in the Kezilesu River in Kashi city were estimated by applying the method of estimation of pollutant loads into the water.The results show that: The emissions sewage treatment plant of COD, NH₃-N, TN, TP from the Kezilesu River in Kashi city account for 61% to 83% within amount of the total emissions in the study area respectively, which is the major pollution source; bean curd factories ranks second, whose the emissions of COD, NH₃-N, TN and TP account for 17% to 37% within amount of the total emissions of pollutants respectively. The contribution rate of the emissions of COD, NH₃-N, TN, TP from life sources are 2 times, 5 times, 4 times and 1.6 times of industrial sources respectively in different types of the pollution sources.
