【摘要】 基于雄县张岗乡坑塘和干渠现状特征及国家2020年消除黑臭水体的要求,本研究以COD_Cr、NH₃-N、TP为主要污染因子,结合水环境容量、污染来源等,提出针对性提升水质的治理方案。结果表明,治理后水质已达到IV类水体标准,水质情况为:开口三村（东南角）坑塘COD_Cr,NH₃-N,TP质量浓度分别为15,0.283,0.1 mg/L;开口三村南排干渠COD_Cr,NH₃-N,TP质量浓度分别为11,0.246,0.09 mg/L。本研究为坑塘和干渠等非常规水源治理提供了技术参考依据。更多还原

【Abstract】 Based on the current characteristics of pit pond and trunk canal in Zhanggang Township of Xiongxian County and the national requirements for eliminating black and smelly water bodies in 2020, this study took COD_Cr, NH₃-N and TP as the main pollution factors, and combined with the environmental capacity of water and pollution sources, proposed targeted treatment schemes for improving water quality. The results show that the water quality has reached the standard of water class IV after treatment. The water quality is:the mass concentration of COD_cr,NH₃-N and TP is 15,0.283,0.1 mg/L respectively in pit pond of Kaikousan village（southeast corner） and the mass concentration of COD_cr,NH₃-N and TP is 11,0.246,0.09 mg/L respectively in the southern drainage channel. This study provides a technical reference for the unconventional water source management of pit and canal.更多还原
