摘要
通过对常熟市辛庄镇5个典型村庄的生活污水和畜禽养殖废水为期1年的采样监测,分析了pH、NO3--N、NH4+-N、TN、PO43--P、TP、COD等污染指标,明确了农村生活污水和畜禽养殖废水的污染特征状况。研究结果表明,生活污水的SS、氮、磷和COD含量很高,超过了国标生活污水排放标准的限值,总体上旱季各指标浓度高于雨季;养殖废水的SS、NH+-N、TP和COD含量超过了国家的日排放标准。
The sewage and livestock wastewater of five typical villages in Xinzhuang town, Changshu city were sampled and analyzed for pollution indicators such as pH, NO3 - -N, NH4＋ -N, TN, PO43- -P, TP, COD. The results showed that the SS, nitrogen, phosphorus and COD content of domestic sewage were high, which exceeded the national standard of living sewage discharge standard limits, and their overall concentrations in the dry season were higher than those in the rainy season. The SS, NH4^＋- N, TP and COD content of aquaculture wastewater exceeded the national emission standards.
