This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

本文分析研究了太阳能热泵热水系统的分类及技术特点，直膨式太阳能热泵技术国内外发展趋势，从六个方面对直膨式太阳能热泵热水系统的研究进行了归纳总结；在此基础之上，从太阳辐射的最佳接收考虑，提出了集热器／蒸发器为圆台侧面的圆台型直膨式太阳能热泵热水器的设计模型，理论上分析了这种热水系统所接收的太阳辐射和得热量，并与圆柱型、平板型的直膨式太阳能热泵热水系统进行对比分析，通过计算机辅助模拟计算出：系统不但可以有效地吸收太阳能，还能有效地吸收空气中的热量，具有良好的热性能；在昆明，以2月为代表的冬季，其太阳辐照较低，系统的制热系数COP值也能达到4.2，效能比EER值为2.9；系统的得热量高出圆柱型、平板型的直膨式太阳能热泵热水系统，节能效果明显。

Poly(vinylidene fluoride-co-hexafluoropropylene) flat membranes were prepared via the TIPS process using diluent mixture of DBP and DEHP. The effects of interaction between PVDF-HFP and diluent mixture on the microstructure and the aggregation structure of PVDF-HFP flat membrane has been investigated.

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。

Colonies on improved agar, when grown 24～48 hours at 37℃ in a candle jar, are 1～2mm in diameter, convex, entire, transparent, glistening, and butyrous. Some strains produce slimy growth. Colonies on clear media are iridescent when observed with obliquely transmitted light.
