摘要
结合珠海市吉大片区不同的排水体制(分流制、截流式合流制),统计分析了吉大水质净化厂4年的进水水质数据,分析发现,分流制下各进水污染物浓度均比相应截流式合流制高;不同排水体制下,分流制中BODs、CODCr、SS的离散程度比截流式合流制大30%,而截流式合流制TN、TP的标准偏差比分流制略大;SS与CODCr的相关性较强,SS与BOD5、TP、TN的相关性较弱;拟选用频率为70%~97%的进水水质指标作为设计进水水质。
Based on the investigation of drainage systems (separate, interception combined systems) in Zhuhai City, this paper statistically analyzed the influent water quality of Jida Wastewater Treatment Plant in four years. The results showed., the dispersion degrees of BODs, CODer, SS were larger in separate system than in interception system by 30 percent, while the standard deviation of TN and TP were a little bit larger in interception combined system than in separate system; SS had a strong correction with CODCr while weak with BOD5, TP, and TN; the inflow water quality indexes with frequency of 70 percent to 79 percent should be employed as the design inflow water quality.
