In the toxicity inhibition test, the accumulated amount of oxygen uptake of BAC was decreased with the increase of Monochloroacetic acid dosages, especially when concentration of MCAA over 100 μg/L. It can be concluded that high concentration of MCAA can inhibit the microorganism's metabolism.

在毒性抑制方面，随著添加加氯消毒副产物一氯醋酸的浓度增加，微生物之累积摄氧有降低趋势，尤其是浓度高於100 μg/L后更为明显，显示MCAA在高浓度下对BAC附著微生物的代谢机制有抑制作用。

In this study,under laboratory conditions,using traditional microbiological culture method,select the Pb2+ stress training of Pistia stratiote and Myriophyllum spicatum L. under water culture, through the changs of root- microbial of Pistia stratiote and Myriophyllum spicatum L.,the results show that bacteria,fungi,actinomycetes have different concentrations under Pb2+ stress. It is specificity of ammonification, nitrification,andanti-Nitrosation after Pb2+ stress.

中文摘要：本研究在实验室条件下，用传统的微生物培养法，选择重金属离子Pb2+在水培条件下对大薸和穗状狐尾藻进行胁迫培养，通过测定大薸和穗状狐尾藻根系的微生物区系及与氮循环有关的四种细菌的数量变化发现：细菌、真菌、放线菌对重金属Pb2+的不同浓度的敏感性不同；重金属Pb2+胁迫对氨化、硝化、亚硝化和反硝化四类细菌的影响也表现出各自的特殊性。

The paper studied the effects of submerged macrophyte and immobilized bacteria on the distribution of four bacteria communities: ammonifying bacteria; nitrosobacteria; nitrobacteria and denitrifying bacteria in water column and sediment of eutrophicted water.

本试验研究了沉水植物伊乐藻和固定化微生物两者相结合对富营养化水体和底泥中4种菌群的氮循环微生物（氨化细菌、亚硝化细菌、硝化细菌、反硝化细菌）分布的影响。

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。

Mineral fuel is the primary energy source in the world today, thereinto coal resource holds in store more than 75 percent in the total energy source. During coal's utilized, nocuousness matter expels into environment through all kings of method and works serious environmental pollution. Desulphurization has become one of primary objects of cleaning coal. At present, there are some primary problems of removing sulfur from coal. It is the size of coal is too small, the time of removing sulfur is too long, the technology is too complicated and the investment is much expensive etal.
