浙江省农村生活污水电导率与水质指标的响应关系分析

针对浙江省嘉兴市、湖州市长兴县、金华市金东区、绍兴市柯桥区开展农村生活污水水质调研工作,结果表明:农村生活污水进出水的电导率、TN、NH3-N、TP等指标间普遍存在极显著相关性.通径分析结果显示,TN的进出水直接通径系数分别为0.472 0、0.455 9,TN是影响进出水电导率的主要指标;电导率-TN含量的拟合方程经...

Response Relationship between Conductivity and Water Quality Index of Rural Domestic Sewage in Zhejiang

An investigation on water quality of rural domestic sewage was carried out in Jiaxing City, Changxing County of Huzhou City, Jindong District of Jinhua City and Keqiao District of Shaoxing City, Zhejiang Province. The results showed that there was a very significant correlation among the conductivity, TN, NH3-N, TP and other indexes of influent and effluent of rural domestic sewage. The results of path analysis showed that the direct path coefficients of TN in influent and effluent were 0.472 0 and 0.455 9, respectively. TN was the main index affecting the conductivity of influent and effluent. The fitting equation of conductivity-TN content showed that the correlation coefficients between actual TN content and fitted TN content of influent and effluent were 0.682 6 and 0.785, respectively, which were significantly correlated at the level of 0.01. This indicated that there was a correlation between conductivity and TN content in water, and conductivity could reflect TN content in rural domestic sewage to a certain extent.
