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。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
