摘　　要：针对当地气候和黑臭湖水污染特点,运用固化载体微生物发生系统原位治理技术+沸石床净化技术进行控源截污,对直排入湖的生活污水进行预处理,使生活污水在入湖前COD和NH3-N、TP含量降至可控范围。同时在湖中不同点位投放固化载体微生物发生系统进行原位修复并改善湖水生态环境。2个月的运行结果表明,湖水水面整洁,臭味消失,水体透明度明显增加,COD和NH3-N、TP的质量浓度由治理前的78 mg/L和5.7、1.38 mg/L分别下降到35 mg/L和1.6、0.18 mg/L,DO的质量浓度提升至3.8 mg/L,主要水质指标达到GB 3838-2002地表水V类标准。不计设备折旧,运行费用约为0.9元/m3,运行成本较低。According to the characteristics of the local climate and black smelly water pollution, the project used situ governance technology with immobilized carrier microbe generation system and zeolite bed purification technology to control the sewage sources for the pretreatment of sewage which straight into the lake, in order to reduce the COD and content of NH3-N, TP into controllable range before the sewage fell into the lake. At the same time, the immobilized carrier microbe generation systems were put in different sites of the lake to purify the sewage in situ restoration and repair ecological environment. The results of 2 months operation showed that, the water clean, the black odor disappeared and the transparency increased, the COD, mass concentration of NH3-N and TP decreased from 78 mg/L, 5.7 and 1.38 mg/L to 35 mg/L, 1.6 and 0.18 mg/L respectively, the mass concentration of DO increased to 3.8 mg/L, the main water quality indexes stably met V class surface water standard of GB 3838-2002. Excluding depreciation of equipment, the operating cost of the project was just about 0.9 yuan/m3.
