摘要
A河道黑臭水体河段长为3. 1 km,劣Ⅴ类水质,采用磁混凝沉淀/强化耦合生物膜(MagCS+EHBR)旁路处理工艺,处理水量为2×10^4m^3/d。近半年的调试及运行监测结果表明,出水指标优于《地表水环境质量标准》(GB 3838—2002)Ⅳ类标准,从而保障了下游考核断面水质达到Ⅴ类标准,运行成本为0. 19元/m^3。通过对工程项目实施的跟踪,取得第一手监测数据,可为黑臭水体治理及河道水质提升工程的应用研究提供科学资料。
The length of black and odorous water body in river A was 3. 1 km and the original water quality was inferior level V. The magnetic coagulation sedimentation( MagCS)/enhanced hybrid biofilm reactor( EHBR) was adopted for bypass treatment with daily water treatment capacity of 20 000 m^3. The commissioning and operation monitoring results in the past half year showed that the main effluent indexes of bypass treatment were superior to level Ⅳ criteria of Environmental Quality Standards for Surface Water( GB 3838-2002),which ensured that the down stream assessment section met levelⅤ standard. The operation cost was 0. 19 yuan/m^3. By tracking the implementation of the project,the first-hand monitoring data could be obtained, which could provide scientific information for the application research of black and odorous water treatment and river water quality improvement project.
