菌胶团

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.

结果表明在进水中BOD/P为100/0.8以上的条件下，污泥的沉降性能良好；当进水中BOD/P分别为100/0.6和100/0.3时，出现高含水率的黏性菌胶团过量生长的现象，发生非丝状菌膨胀；在进水中BOD/P为100/0.4的条件下，发生更严重的非丝状菌膨胀，试验中还研究了磷缺乏条件下微生物对氮源和磷源利用率的变化。

Through understanding the distribution of DO and substrate within a biological floc, the effect of DO and F/M on sludge production was analyzed from theoretical aspect.

通过了解DO和基质在菌胶团内部的分布情况，从理论上分析了DO和F／M对污泥产率的影响。

Rotifer, wireworm exist in zoogloea at salt concentrations of 10000 mg/L while protozoa and metazoan disappeared when calcium chloride concentration is 30000 mg/L.

菌胶团中的微生物种类随着盐度的升高而减少，在盐度为10000mg/L时，有轮虫、线虫多种原生动物和后生动物，当盐度为30000mg/L时，菌胶团中的原生动物和后生动物消失。

Therefore, it created a favorable environment for the growth of zoogloea and made the recovery of sludge bulking of filamentous microbe easily.

创造有利于菌胶团生长的微生物环境可有效地恢复由丝状菌引起污泥膨胀。

Significant loss of GEMs was not observed but strong growth activities, formation of biofilm and zoogloea on the surface of immobile particles were observed via scanning electron microscope. The mechanical stability of the particles remained unchanged after nearly two-month operation.

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。

The result showed that manganese redox bacteria all have metachromatic granules and Poly-β-hydroxy butyrate, and easy to form flora, which are suitable for the growth in oligotrophic water environment.

研究表明，锰氧化还原菌均具有异染颗粒和类脂粒，易形成菌胶团，适于在贫营养水环境中生长。

Biofilm is fragmented and mainly composed of zoogloeas on the cracks and concaves of the filter media. The bacteria in biofilm or activated sludge of aerobic filter are mainly bacilus and filamentous bacteria.

滤料上的生物膜是不连续的，微生物主要以菌胶团的形式存在于滤料上的孔洞内和表面凹陷处；无论是滤料上的生物膜，还是滤床孔隙内的活性污泥，其中的细菌以各种杆菌及丝状菌为主。
