摘　　要：为了提高黑臭河道水体的治理效率,以某黑臭河道污水水样为研究对象,对其不同取样点以及不同取样时间段的水质进行了监测分析,并采用“微孔曝气+生物质吸附材料+微生物菌剂”的组合工艺措施对黑臭河道污水进行了综合治理,考察了不同因素对污水处理效果的影响。结果表明,目标黑臭河道4个取样点不同时间所取水样的平均透明度、溶解氧(DO)、氧化还原电位(ORP)和氨氮(NH_(3)-N)浓度均达到轻度黑臭水体的标准,河道水质存在严重的污染现象。在曝气强度为250L·h^(-1)、生物质吸附材料投加量为8g·L^(-1)、微生物菌剂投加量为0.035g·L^(-1)的条件下,经过“微孔曝气+生物质吸附材料+微生物菌剂”组合工艺处理后的河道污水水质指标显著改善,河道黑臭现象得到了消除,综合治理效果较好。In order to improve the treatment efficiency of black and odorous river water,a sewage sample from a certain black and odorous river was taken as the research object.The water quality at different sampling points and different sampling time periods was monitored and analyzed.A combination of "microporous aeration + biomass adsorption material + microbial agent" technology was used to comprehensively treat black and odorous river sewage,and the influence of different factors on the sewage treatment effect was investigated.The results show that the average transparency,dissolved oxygen(DO),redox potential(ORP),and ammonia nitrogen(NH_(3)-N)concentration of water samples taken at different time points in the target black and odorous river reach the standard for mild black and odorous water,indicating serious pollution of the river water quality.Under the conditions of aeration intensity of 250L·h^(-1),biomass adsorption material dosage of 8g·L^(-1),and microbial agent dosage of 0.035g·L^(-1),the combined process of “microporous aeration + biomass adsorption material + microbial agent”significantly improved the water quality indicators of river sewage,eliminated the black and odorous phenomenon of the river,and achieved good comprehensive treatment effect.
