中文摘要:

以南昌某典型产城融合区污水处理厂为调查对象，研究污水在“厂〖CD*2〗网〖CD*2〗源”空间迁移过程中水质水量的变化特征。结果表明：降雨天污水厂进水量显著高于无降雨天，且进水浓度降低，降雨量、降雨强度、晴/雨天和季节对污水厂进水水质特征具有显著影响（p=0001）。原生污水仅占污水厂进水总量的6165%，存在大量外水混入管网的情况。污水荧光特征峰工业区以类色氨酸类和类富里酸类物质为主，居民区以类色氨酸和酪氨酸类物质为主。企业排水污染负荷仅占污水厂进污量的960%，居民小区总排口COD、NH3 N和TP测定均值分别为2275mg/L、4972mg/L和418mg/L，污水浓度从小区单元出户到总排口的迁移过程中出现不同程度的降低。

英文摘要:

Taking the sewage treatment plant in a typical industry city integration area in Nanchang as the investigation object， this paper studied the variation characteristics of the quality and quantity of sewage during the spatial migration process of “plant network source”. The results showed that the influent flow on rainy days was significantly greater than that on non rainy days， and the influent concentration decreased. Rainfall， rainfall intensity， sunny/rainy days and season had significant impacts on the influent water quality characteristics（p=0001）. Raw sewage only accounted for 6165% of the total influent flow， and there was a large amount of external water mixed into the pipeline network. The fluorescence characteristic peaks of sewage from industrial areas were mainly attributed to tryptophan like and fulvic acid like substances， while those from residential areas were mainly tryptophan like and tyrosine like substances. The pollution load of enterprise drainage only accounted for 960% of the influent flow. 〖GK!87mm〗The average concentrations of COD， NH3 N and TP at the total discharge outlet of the residential community were 2275 mg/L， 4972 mg/L and 418 mg/L， respectively. During the migration of sewage from individual household unit to the final outfall， its concentration decreased to varying degrees.
