摘　　要：针对目前城市污水处理工艺中的交替式运行工艺存在的污泥分布不均匀、容积和设备利用率低的问题,结合新型AICS工艺,分别在无内循环、开启部分内循环和完全开启内循环系统三种情况下进行污泥分布试验研究。结果表明:完全开启内循环系统时,各反应池的污泥分布趋于均匀化,池容利用率提高到0.71,系统同时呈现推流式和完全混合式两种水力特点。Aimed at the present problems arisen in the alternated internal cyclic system （AICS） for municipal sewage treatment, such as the asymmetric distribution of sludge, the lower utilizable ratio of volume and equipment, and combined with a new process of AICS, the experiment was carried out in three conditions of none internal circulation, partial internal circulation and full internal circulation. By analyzing the result of experimentation, it could be recognized that at case of full internal circulation the sludge distribution make more homogeneous, the utilizable ration of tank volume is increase to 0. 71, both the push flow system and continuous stirred systems are presented.
