Studied the solid particles cyclone separation under structural parameters and operating parameters of different hydrocyclone, the results showed that major factor influence split ratio is in the ratio of entrance to exit pressure of hydrocyclone. Exit pressure has a certain influence on the split ratio, the various of the diameter and cone angle of hydrocyclone (in the ratio of entrance to exit pressure is constant) have no influence on split ratio; With diameter and cone angle increase, the separation granularity gradually increasing and recovery ratio decreasing; With entrance pressure increase, the separation granularity of hydrocyclone decrease, the split ratio of underset will increase slowly; With the diameter of overflow pipe increase, the separation granularity of hydrocyclone increasing and recovery ratio decreasing; With the diameter of underset pipe increasing, the separation granularity of hydrocyclone decreasing and recovery ratio increasing.

在不同的水力旋流器结构参数和操作参数下，对固体颗粒的旋流分离进行了分析研究，结果表明：旋流器的排出口比是影响分流比的主要因素，进口压力对分流比有一定影响，水力旋流器的直径变化和锥段角度变化对分流比基本上没有影响；随着直径、锥段角度的增大，分离粒度逐渐增大，回收率降低；随着入口压力增大，水力旋流器的分离粒度变小，底流的分流比会缓慢增加；随着溢流管管径的增加，分离粒度增大，分流比明显减小，回收率降低；随着底流管直径的增加，分离粒度减小，分级效果明显下降，回收率会增加。

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。

In the initial stage of the bioleaching, when the bacteria are not active, the chemical oxidation of ferric irons to the solid sulfide minerals is primary; While in the whole course of the bioleaching, it is very limited; ferric irons inhibit the bacterial activity, lower the oxidational ability of the bacteria to ferrous irons in the liquid phase; ferric irons and their precipitations reduce the quantities of the attached bacteria and their activity, and have bad influence on the direct bioleaching action.

结果表明，在浸出的初始阶段，Fe3+的化学氧化作用是主要的；但在整个金属浸出过程中，Fe3+的化学氧化作用是很有限的；Fe3+对T.f菌有一定的抑制作用，降低了它们对液相中Fe2+的氧化能力；Fe3+及其沉淀使细菌在固体矿物颗粒表面的吸附量减少，降低了吸附细菌的活性，从而影响了细菌的直接氧化浸出作用。
