摘要
采用拦污动力调控技术、净化强化技术和生态修复技术的综合措施,对多源污染水体水环境进行整治提升。为改善补水水源水质,采用人工湿地清水水源工程对河湖补水原水进行深度净化,系统处理规模为8000 m^(3)/d,水力负荷为0.57 m^(3)/(m^(2)·d),人工湿地系统对BOD5和TP去除率可达到50%以上,CODCr、氨氮、TN去除率均可达到45%以上。综合治理后,主要水质指标达到地表水Ⅳ类标准,景区水环境质量得到了极大的改善。
To improve the water environment of multi-source pollution,comprehensive treatment measures were adopted,including power regulation technology,purification strengthening technology and ecological restoration technology.In order to improve the water quality of supplementary,the constructed wetland system was used to deep purification of river water.When the treatment scale of constructed wetland system was 8000 m^(3)/d,and the hydraulic load was at 0.57 m^(3)/(m^(2)·d),the average removal rates of BOD5 and TP reached more than 50%,CODCr,NH3-N and TN as high as 45%.After comprehensive treatment,the main water quality indicators reached standard of class IV of surface water environmental quality.The water quality of scenic spots had been improved greatly.
