The results showed that the sludge settled properly at a influent BOD/P of 100/0.8. When the BOD/P was 100/0.6 and 100/0.3 respectively, an excessive growth of viscous Zoogloea with high moisture content was observed and non-filamentous bullring occurred. When the value of influent BOD/P was 100/0.4, more serious non-filamentous bulking occurred. Furthermore, under the condition of phosphorus deficiency the effect of microorganism on the nitrogen and phosphorus sources utilization rate were also studied in the experiments.

在整个反应过程中，没有出现大量工程菌流失的现象，同时在固定化颗粒的表面以及浅层均观察到了大量工程菌菌体，固定化颗粒的表面还出现了生物膜和菌胶团，反应结束时，颗粒形态完好，强度满足本工艺条件下长期使用的需求。

Filamentous bacteria exists in every activated sludge system,the problem of sludge bulking will happen only when filamentous bacteria grows over than zoogloea ,the obove-mentioned problem will not occur when filamentous bacteria and zoogloea equally grow.

任何活性污泥系统中都存在着丝状菌，在丝状菌与菌胶团细菌平衡生长时，不会发生膨胀污泥问题，只有当丝状菌生长超过菌胶团细菌时，就会出现污泥膨胀问题。

The sludge in SBMBR1 presented granular characteristics and settled very well. The sludge in SBMBR1was brown and the sludge flocs was smashed by the shear force due to high intensity of aeration. The sludge size decreased and the sludge flocs blended with water forming ropy solutions, and there was no distinguish interface between water and sludge. Low sludge age and high loading operation enabled the sludge in SBMBR1 keeping higher sludge activity and the MLVSS/MLSS ratio and SOUR values of SBMBR1 were higher than SBMBR2. Both in SBMBR1 and SBMBR2, there were large amount of zoogloea, bacillus, coryneform of bacteria, and pediococcus. However, in SBMBR1 there were also a lot of Protozoa like epistylis and etc. A certain amount of filamentous bacteria can also be found in SBMBR1. The biological species in SBMBR1 were much more abundant than that in SBMBR2.3. Membrane fouling on flat-sheets membrane was observed and analyzed with AFM, SEM and TEM. After the measurement of membrane surface EPS and membrane surface ETX analysis, the pollutants composition on the surface of flat-sheets membrane was calculated.

从外观观察SBMBR1反应器中的活性污泥呈浅黄色，随着运行时间的增加，污泥粒径逐步增加，SV、SVI值逐步下降，呈现出较强的颗粒特征，沉降性能良好；SBMBR2污泥呈土黄色，污泥絮体被高强度的曝气所产生的切应力所打碎，污泥粒径迅速降低，絮体较为细碎，和水相混合成均一粘稠的溶液，看不到泥水分界面；低泥龄、高负荷运行，使得SBMBR1可以保持较高的微生物活性，MLVSS/MLSS值、SOUR值均高于SBMBR2；两级反应器活性污泥中均有大量的菌胶团，长杆菌、短杆菌和球菌是构成主体，但SBMBR1活性污泥中含有大量固着型原生动物如累枝虫等，还存在着一定数量的丝状菌，生物相要比SBMBR2丰富。3、借助原子力显微镜、扫描电镜、透射电镜等手段对平板膜污染现象进行观测和分析，并通过膜表面污染物EPS测定、污染膜表面能谱分析，得出平板膜表面污染物的组成。

Ecological control of sludge bulking is highly important, especially in preventing sludge bulking through ecological relationship such as prey and autoeciousness of microorganisms.

指出丝状菌污泥膨胀的实质是活性污泥微生态系统平衡失调，微生物群落结构与功能发生变化，丝状菌种群代替菌胶团菌群成为优势种；利用微生物种群之间的捕食、寄生等关系控制污泥膨胀的生态学调控方法，是实现控制丝状菌污泥膨胀，保持污泥微生态系统稳定，获得良好污水净化效果的治本之法。
