According to the above study result, the diversity of microorganisms population in the SUFR system is complex and the bio-community formed in the SUFR system is stable. The close relations between abundance of bacteria and nutrients were found. The correlation between heterotrophic bacteria and COD was 0.949. The correlation between organic phosphate bacteria and TP was 0.815. The correlation between nitrosobacteria and NH3-N was 0.909. The correlation between disnitrifier bacteria and TN was 0.653. These inneglectable great factors effecting on phosphorus-uptake and phosphorus-release of phosphorus accumulating organisms are the influent COD、the concentration of DO、the sludge retention time、the temperature. The diversity of organic phosphate bacteria population in the SUFR reactor was complex and there is no phosphate bacteria taking the absolute superiority in quantity. The near-native pure culture method powerfully complement the traditional pure culture technique and enrich culture technique. The sludgy bioactivity is very good in whole SUFR reactor. By the quality of being biochemistry, the anaerobic phase is higher than anoxic phase and the anoxic phase is higher than aerobic phase of SUFR.
通过以上试验内容研究发现,SUFR 系统中的微型动物种群较多,微生物生态系统稳定;系统中微生物的数量与营养盐的含量密切相关,其中总异养菌与COD的相关系数r 为0.949,有机磷细菌与TP 的相关系数r 为0.815,亚硝化菌与NH4+-N的相关系数r 为0.909,反硝化菌的数量和TN 的相关系数r 为0.653;污水生物除磷工艺中进水COD 的浓度、DO 浓度、泥龄的长短、温度都是影响聚磷菌释磷及吸磷效果的不可忽视的因素;SUFR 系统中的磷细菌呈现种群多样化的趋势,没有占绝对优势数量的磷细菌;微孔滤膜近自然培养法是对传统纯培养技术和富集培养技术的有力补充;整个SUFR 反应器系统中污泥的生物活性很好,就可生化性来讲,厌氧反应器大于缺氧反应器大于好氧反应器;按照动力学方程式求出的细胞生长动力学特征值和SUFR 脱氮除磷系统工艺的实测值结果基本吻合。

In the situation of varied water quality of influent, membrane permeate COD was all less than 20mg/L, NH〓-N was less than 1mg/L and turbidity was less than 1 NTU. Because the membrane surface formed gel layer in the filtration process, which reduced membrane pore size efficiently removed nosogenetic germ and virus and attained the demand of water quality standard in wastewater reuse.
在进水水质波动的情况下,膜出水COD值均小于20mg/L,NH〓-N小于1mg/L,浊度小于1NTU;由于在过滤过程中膜面形成了凝胶层,起到了减小膜孔径的作用,从而达到致病菌和病毒的有效去除,能够满足污水回用于杂用水时对水质的要求。

It was different of contents of same mineral element inthe leaves of Malania olefera because of different areas, but the differences was notnotable. The influence of mineral element and soil elements on Malania olefera wasnitrogen, iron, manganese, zinc, potassium, copper from most to least, and four ofthem were belong to microelement. However, the lack of copper and serious lack ofzinc and iron in the soil influent the growth of Malania olefera. It had been made through the analysis of morphologic and anatomicalcharacteristics of root, stem, leaf, flower, fluid and seed that Malania olefera notonly had the primitive character but also had the evolution character, which had thevital significance on Olacaceae classification.

For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.

The present research situation about AB process in and out of our country was analyzed in this paper. In addition to a concentrated study of the factors affecting sedimentation performance of A-step activated sludge, the rule of microbe multiplication, yield of activated sludge in A-step and treatment of low-concentration sewage were also involved in this paper. The main conclusions are as follows:(1) The study on factors affecting sedimentation performance of A-step activated sludge shown that the inflow SS distinctly improve sedimentation performance of activated sludge, the less influent SS makes the sludge bulking easy, and the pythogenous sewage evidently worsen sedimentation performance of activated sludge.
