The sludge settling characteristic is satisfying with SV varying from 22 to 30 and SVI varying from 58 to 80ml/g.The sludge bulking problem has been avoided successfully. The excess sludge can be thickened to 3%-4 %. The alkalinity remains equilibrious between the nitrification and denitrification in SBR-BAF system. The COD and TP loading of SBR are 2.08kgCOD/kgMLSS·d and 41.68gTP/kgMLSS·d, respectively. The NH4+-N loading of BAF is 1.16kgNH_4~+-N/m~3.d. The total HRT is about 10 hours which is only about half of suspended growth process for simultaneous phosphorous and nitrogen removal. Under the above mentioned high loadings and short HRT, the mean removal efficiency of COD, TP, NH4+-N, TN is 96%, 98%, 93%, and 84%, respectively. The mean effluent concentration of COD, TP, NH4+-N, TN, SS is 20mg/L, 0.23 mg/L, 3.24 mg/L, 7.68 mg/L, 5 mg/L respectively, which means every index can meet the first class of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.

最后，以上述最佳运行参数控制SBR-BAF系统运行，长期运行结果表明：系统中悬浮污泥的絮凝、沉降性能良好，SV值为22~30，SVI值为58~80，不再有污泥膨胀之虞，而且可以对剩余污泥进行重力浓缩，浓缩后污泥浓度可以达到3~4%；短程硝化和反硝化使得系统可以维持碱度平衡，无需额外补充碱度；系统在高负荷(SBR反应器COD负荷为2.08kgCOD/kgMLSS.d，TP负荷为41.68gTP/kgMLSS.d，BAF反应器NH4+-N负荷为1.16kgNH_4~+-N/m~3.d)、低水力停留时间(SBR反应器9h，BAF反应器1h，总计10h，约为同步脱氮除磷悬浮污泥工艺的一半)下稳定高效运行，对COD(不计BAF加入的外碳源)、TP、NH_4~+-N、TN的平均去除率为96%、98%、93%、84%，出水COD、TP、NH4+-N、TN、SS的平均浓度为20mg/L、0.23 mg/L、3.24 mg/L、7.68 mg/L、5 mg/L，各项水质指标均达到《城镇污水处理厂污染物排放标准》(GB 18918-2002 )一级标准的A标准的要求。

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.
