摘要
对南方某市主要城市污水处理厂恶臭源的排放浓度进行监测,以H2S和NH3为主要监测指标。监测结果表明：在污水处理厂厂界内,臭气污染源主要集中在进水区、格栅区、曝气沉砂池以及污泥处理区域,厂界臭气浓度均不超标。同时,对该市典型污水处理厂的主要恶臭污染源H2S和NH3进行了13个月的连续监测;结果表明,构筑物内恶臭气体成分H2S的排放浓度为0.02-69.84ppm,NH3为0-0.37ppm,主要臭气污染物为H2S;污水处理厂进水泵房、格栅以及曝气沉砂池的臭气浓度呈现夏高冬低的特征,具有季节变化的特征。
The major municipal wastewater treatment plant odor sources emission concentrationwas monitored with the major indexes of H2S and NH3 in a city in South China. The resultsshowed that in the wastewater treatment plant area, the odor sources were mainly located in waterentering district, griller district, aerated grit chamber, and sludge treatment district and the aver-age odor concentration in wastewater treatment plant area met the standards. Meanwhile, H2 S andNH3 sources in a typical wastewater treatment plant in this city were also monitored continuouslyfor 13 months. The results showed that H2S concentration in emission was 0.02-69.84 ppm andNH3 was 0-0.37 ppm. The major odor source was H2S. The odor concentration in water intakepump station, griller, and aerated grit tank showed a pattern of high value in summer and low inwinter and the characteristics of seasonal changes.
