The present research situation about AB process in and out of our country was analyzed in this paper. In addition to a concentrated study of the factors affecting sedimentation performance of A-step activated sludge, the rule of microbe multiplication, yield of activated sludge in A-step and treatment of low-concentration sewage were also involved in this paper. The main conclusions are as follows:(1) The study on factors affecting sedimentation performance of A-step activated sludge shown that the inflow SS distinctly improve sedimentation performance of activated sludge, the less influent SS makes the sludge bulking easy, and the pythogenous sewage evidently worsen sedimentation performance of activated sludge.

本文分析了国内外AB工艺的研究现状，对A段活性污泥沉降性能的影响因素；A段的微生物增殖规律、活性污泥产量以及A段工艺处理低浓度城市污水等问题进行了试验研究，得出了以下结论：（1）对A段活性污泥沉降性能影响因素的研究表明：进水中的SS对污泥沉降性能有明显的改善作用，如果进水中SS较少，易导致污泥膨胀；而腐化污水对活性污泥的沉降性能有显著的不良影响。

With the improvement of requirement to sewage reuse treatment and the degree of robotization,biological aerated filter has been paid more and more attention by the investigator of sewage treatment for its inherent advantages.

In the sewage treatment compared with the popularity of Western developed countries, such as the lunwen114Netherlands, Germany, Britain, the United States, 30% to 50% of the sewage treatment plant have occurred in varying degrees of sludge bulking problem.

在污水处理比较普及的西方发达国家，象荷兰、德国、英国、美国，有30％～50％的污水处理厂都发生过不同程度的污泥膨胀问题。

This flocculating agent has good water solubility. Dissolving rate is quicker than traditional synthesized flocculating agent such as poly-propionamide. It overcomes flaws of slow dissolving rate and inconvenient field using of traditional poly-propionamide; because of copolymerizing with natural product Amorphophallus konjac, it has advantage of strong natural product biodegradation. After be used, it do not cause secondary pollution. It can be used in process of city domestic sewage and industrial sewage.

本发明絮凝剂具有良好的水溶性，溶解速度比传统的合成类絮凝剂如聚丙酰胺类更快，克服了传统聚丙酰胺溶解速度慢，现场使用不方便的缺点；而且由于与天然产物魔芋胶共聚，同时具有了天然产物可生物降解性强的优点，使用后不易造成二次污染，可以应用于城市生活污水和工业废水处理中。
