摘　　要：以城郊农村黑臭水体为例,系统研究了农村黑臭河道综合整治。在对目标河道所在区域的气候特征、地势地形、用地类型、水系连通情况以及目标河道的感官现状、水质现状、污染成因等进行充分的资料调研和现场踏勘的基础上,结合流域水质管控目标,确定治理目标与方案,并在工程实施完成后对目标河道进行了为期1年的调试养护。研究结果表明,控源截污措施对水体黑臭的消除及对NH3-N的控制效果明显,而CODCr和TP则在调试后期生态系统逐渐恢复的情况下才得到有效的控制;治理前后目标河道感官对比明显,养护后期目标河道平均透明度稳定维持在0.8 m以上,大型水生植物生长态势良好,目标河道周边环境得到有效改善提升。目标河道黑臭水体综合整治过程的记录和分析可为同类工程的实施提供技术与模式参考。Taken a rural black-odor river as an example,the systematic research was conducted on rural black-odor water body renovation.The data climate characteristics,topography,used land types,river system,sensory situation,water quality,pollution causes were fully investigated and surveyed on site for the river basin.Combined with the water quality,the renovation target and scheme was determined.One-year maintenance was made for the river after construction.Research results shows that pollution sources control had an obvious effect on elimination of black-odor water and reduction of ammonia nitrogen(NH,-N).However,concentration of chemical oxygen demand(CODc)and total phosphorus(TP)wasn't got effective controlled untill the water ecosystem began to recover;Sensory quality of the river improved a lot after remediation.In the latter part of the maintenance period,average transparency of the river is higher than O.8 m;The macrophytes grow well;The improvement of surrounding environment is great.The detailed recording and analysis of black-odor river renovation provides reference for similar projectin this study.
