中文摘要:

采用悬挂链曝气式接触氧化工艺在不同回流比下处理城市河道污水,应用磷脂法、TTC-脱氢酶活性法和MPN法研究了载体表面生物膜特性,考察了回流比对生物膜特性和水质净化效果的影响.结果表明:在100%～300%之间,回流比对好氧区内生物膜量和生物活性影响不大,而回流比越大,缺氧区内生物膜量越多,NH⁺₄-N和TN的去除效果越好；回流比大于200%后,对缺氧区生物膜量及水质净化效果的影响减弱；最佳回流比为200%,对COD、NH⁺₄-N、TN和TP的平均去除率分别为78.0%、80.46%、66.4%和56.5%,出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级标准B标准.

英文摘要:

A contact oxidation process with suspended chain aerator was applied to treating the wastewater of urban rivers to study the superficial biofilm characteristics by the determining methods of phospholipid,dehydrogenase activity and MPN and influence on biofilm characteristics and water quality decontamination under different internal recirculation ratios.The results showed that the internal recirculation ratio weakly influenced biomass and microbial activity in the aerobic zone between 100% and 300%.The greater the internal recirculation ratio was,the more biomass in the anoxic zone was and the better efficiency on removal of NH₄₊-N and TN were.When the internal recirculation ratio was greater than 200%,influence of the internal recirculation ratio on biomass in the anoxic zone and efficiency of wastewater removal lowered.Average removal rates of effluent of COD、NH₄₊-N、TN and TP was 78.0%,80.46%,66.4% and 56.5%,respectively,reaching B standard of discharge standard of pollutants for municipal wastewater treatment plant(GB 18918—2002) with the best internal recirculation ratio of 200%.
