摘　　要：随着人类社会的迅猛发展,水污染成为了人类发展共同面临的挑战。以江门市某污水处理厂为例,为准确掌握该厂污水水质,对污水的悬浮物(SS)、重铬酸盐指数(COD_(Cr))、总氮(TN)、总磷(TP)和五日生化需氧量(BOD_(5))等进行了监测,分析其变化规律。结果表明,江门市某污水处理厂SS、COD_(Cr)、TN、TP、BOD_(5)的去除率均保持在较高水平,出水的各指标均小于标准最高允许排放浓度;SS、TN、TP呈现明显的季节特性,进水各指标均夏季远低于冬季;COD_(Cr)去除率夏季高于冬季,TP的去除率夏季低于冬季。该水质监测分析为当地实际污水处理和水质监测工作提供了科学指导。With the rapid development of human society,water pollution has become a common challenge faced by human development.Taking a sewage treatment plant in Jiangmen City as an example,in order to accurately grasp the water quality of the plant's sewage,the suspended matter(SS),bichromate index(COD_(Cr)),total nitrogen(TN),total phosphorus(TP)and five-day biochemical oxygen demand(BOD_(5))of the sewage were monitored and analyzed for their changing patterns.The results showed that the removal rates of SS,COD_(Cr),TN,TP,and BOD_(5) in a sewage treatment plant in Jiangmen City remained at a high level,and all indicators of the effluent were lower than the standard maximum allowable discharge concentration;SS,TN,and TP show obvious seasonal characteristics,and all indicators of inflow were much lower in summer than in winter;The removal rate of COD_(Cr) was higher in summer than in winter,and the removal rate of TP was lower in summer than in winter.This water quality monitoring analysis provides scientific guidance for local actual sewage treatment and water quality monitoring work.
