Instead of a popular sedimentation adopted in urban sewage treatment system, a new sewage treatment system composed of foam separation and filtration was studied.In the proposed system, at first, suspended matters are removed by foam separation process. Then the rest of suspended matters and dissolved matters are removed by filtration which is expected both physical and biological treatments.These experiments obtained the following results ; optimum conditions at foam separation process were that flow, PAC dosage and casein dosage were 10 l/min (HRT 6 min), 20 mg Al/l and 10 mg/l , respectively. The average of turbidity and total organic carbon (TOC) removals at the foam separation process were 87% and 52%, respectively. Most part of organic substances in effluent from the foam separation process was dissolved matters which were easily biological decomposed The effluent of foam separation process was treated by the filtration (HRT 2h, filtration rate 20m_/d). the result was as follows ; the average of turbidity and TOC removal through the whole system with the filtrarion reached 92% and 81%, respectively.

研究了一种新型的泡沫分离-过滤污水处理系统，以代替目前城市污水处理系统中普遍采用的沉淀法，该系统首先采用泡沫分离工艺去除悬浮物，然后采用过滤法去除悬浮物。实验结果表明，泡沫分离工艺的最佳工艺条件为：流量10 l/min（HRT 6 min），PAC投加量20 mg Al/l，酪蛋白投加量10 mg/l。在泡沫分离过程中，浊度和总有机碳（TOC）的平均去除率分别为87%和52%。泡沫分离出水中大部分有机物为易生物降解的溶解性物质，采用过滤法（水力停留时间2 h，滤速20 m2/d）处理泡沫分离出水。试验结果表明，整个系统对浊度和TOC的平均去除率分别达到92%和81%。
