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。

The plastic alloy is refers to two kinds of or two kind of above polymers becomes the microscopic phase splitting macroscopic even multi-components system through some way blending, the plastic alloy both includes the product of the pure physics blending, and includes block, the graft copolymer as well as the polymer compound material which the chemical change becomes during the course of milling.

塑料合金是指两种或两种以上聚合物通过某种方式混合而形成微观分相宏观均匀的多组分体系，塑料合金既包括单纯的物理混炼产物，又包括嵌段、接枝共聚物以及混炼时发生化学变化而成的聚合物复合材料。

The wood of a gum tree .Having a single, undivided trunk with lateral branches, as in spruce trees.

贯顶的，塔状的主轴延伸成不分枝的茎或杆的，如云杉

France Holly Yijian not cutting deep division branchlets cutting-down section, depth to 1 cm soil trees were suitable; the depth of the cutting insert for the next node, in one centimeter, and the cuttings from 45 degrees tilt, shallow inserted Chacha to advance rooting cuttings survived.

法国冬青扦插宜浅不宜深，小枝分株扦插平截面向下，深度以母株人土1厘米为宜；大枝扦插的深度为下一茎节插入上中1厘米，插穗与地而成45度左右倾斜，浅插斜插有利于插条提前生根成活。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
