城市污水排放与浑河(沈阳段)水质相关性分析

首先,在论述沈阳市城市排水系统概况及"十五"期间沈阳市城市污水排放状况的基础上,对受城市污水排放影响较大的浑河沈阳沈大铁路桥至七台子桥,水质中主要污染物化学需氧量、氨氮浓度值和城市污水中化学需氧量、氨氮浓度值的变化情况进行了相关性分析;采用综合污染指数法和断面污染物通量计算方法,对该河段水质综合污染指数与城市污水入河污染物总量进行了相关性分析,同时,对断面污染物通量与城市污水入河污染物总量进行了相关性分析,从中可以量化得出城市污水排放与地表水水质的相关性.

Correlation Analysis Between Urban Sewage Discharging and Quality in Hunhe River(Shenyang)

Based on the brief discussion of urban drainage system and urban sewage discharging in the city of Shenyang, this thesis makes correlation analysis between the concentration of COD and NH3 - N in Hunhe River and urban sewage. And the correlation analysis is also made between the synthetic pollution index and the total amount of contaminant from urban sewage into the river. And ultimately, an additional correlation analysis is made between the contaminant flux through the cross section and the total amount of contaminant from urban sewage into the river.
