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日本人妻黄色三级小视频、the concentration of DO、the sludge retention time美女被干黄色网站、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.

With retention time prolonged, the concentrations of TN, NH4(superscript +)-N and TP of domestic sewage were obviously reduced in all floating-bed systems, however the NO4(superscript +)-N concentrations were gradualjy accumulated due to the stronger nitrification than denitrification. The plants in floating-bed system increased significantly the N2O flux, which was 174.44μg/(m^2h), 82.19μg/(m^2h), 112. 49μg/(m^2h) and 44.81μg/(m^2h), respectively, for the Lolium mutliflorum, Oenanthe javanica, Vetiveria Zizanioides arid none-plant floating-bed systems.

Among the economic crops, pachyrhizus leaf had the most remarkable treating effect, the COD treating capacity per day per unit area was 4.01g, that is, a 50% treating rate; the BOD treating capacity was 1.15 g, that is, a 35% treating rate; the TP treating capacity was 0.23 g, that is, a 16% treating rate; the TN treating capacity was 1.87 g, that is, a 74% treating rate; however, the treating effect decreased as the total amount of pollution entering this system increased by raising the water volume, which was mainly owing to the relatively short hydraulic retention time.
