中文摘要:
      通过对上海市3家城镇污水处理厂主要污水处理工艺臭气收集处理装置进出口有组织排放和二沉池等敞开液面无组织排放氨采样,研究污水处理厂氨气排放特征,建立污水处理厂分季节本地化氨排放系数,并计算2019年上海市城镇污水厂氨排放量。结果表明:3家污水处理厂氨排放系数平均为4.8 mg/m3,其中污水处理环节氨排放系数为3.3 mg/m3,污泥处理环节氨排放系数为1.5 mg/m3。2019年上海市城镇污水处理厂氨排放量为10.3 t。
英文摘要:
      The ammonia emission characteristics of three municipal sewage treatment plants in Shanghai were studied by sampling the organized emission of odor collection and treatment devices at the inlet and outlet and the unorganized emission of ammonia from the open liquid surface of secondary sedimentation tank.Based on the four seasons of spring,summer,autumn and winter,the ammonia emission coefficient of local sewage treatment plants with organized and unorganized,sewage and sludge treatment was established.The ammonia emission of Shanghai municipal sewage treatment plant in 2019 was calculated.The results showed that the average ammonia emission coefficient of the three sewage treatment plants was 4.8 mg/m3,in which the ammonia emission coefficient of sewage treatment was 3.3 mg/m3 and that of sludge treatment was 1.5 mg/m3.In 2019,the ammonia emission of Shanghai urban sewage treatment plant was 10.3 ton.
