Compared with that of 3Cr13 alloy, the oxidation resistance of the composites containing 5 vol.%TiC particle was improved greatly at 850℃, but the improvement was relatively limited at 950℃. But the oxidation resistance of 1Cr18Ni9 composites containing 5 vol.% TiC particle was obviously improved at 950℃, and at 850℃ the improvement is not large. The TiC particle can improve the oxidation resistance mainly was by developing the oxidation selectiveness of the Cr element as to change the phase constitution of the oxidation film, to alleviate the production of the stress in the oxidation film and to improve the cohesive force of the oxidation film or matrix interface and the chemical combination of the oxidation film.

与3Cr13合金相比,含5%volTiC颗粒的复合材料在850℃的抗氧化性能得到大幅度提高,而在950℃复合材料的抗氧化性能提高作用却是有限的;与1Cr18Ni9合金相比,含5%volTiC颗粒的复合材料在850℃的抗氧化性能略有提高,而950℃复合材料的抗氧化性能提高却是明显的;TiC颗粒可以提高两种基体合金抗氧化性能,主要是通过促进Cr的选择性氧化,进而改变氧化膜的相组成、减缓氧化膜内应力的产生、增加氧化膜/基体界面凝聚力及提高氧化膜化学结合力而实现的。

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。
