摘　　要：本文基于前研究学者针对高原独特的环境因素进行城市污水多种处理工艺试验研究,为了找出适合高原生境下在污染物去除方面较好的城市污水处理工艺,对各工艺去除污染物(COD、TN、TP和NH_(3)-N)的去除率和出水浓度达标率作了对比分析。结果表明:一体化MBR和前置厌氧SBR工艺分别对COD和NH_(3)-N的去除效果最佳,A^(2)O工艺同时对TN和TP的去除效果最佳。此外,A^(2)O工艺同时去除4种污染物的效果最佳,并且此工艺处理污染物进水浓度较高,因此,值得考虑A^(2)O工艺作为高原生境下的城市污水处理主流工艺。前置厌氧SBR和一体化氧化沟工艺对4种污染物一级A标准达标率均是100%,但污染物去除率并不都是最佳的,主要可能是因为进水浓度低,表明这两个工艺适合高原生境下处理污染物浓度低的水质。该对比评估研究可对高原地区城市污水处理工艺技术应用发展提供一定的帮助。In this paper,based on the experimental study of various municipal wastewater treatment processes conducted by previous researchers for the unique environmental factors of the plateau,the removal rates of pollutants(COD,TN,TP and NH_(3)-N)and the effluent concentration compliance rates of each process were compared and analyzed to find out the better municipal wastewater treatment processes for pollutant removal in the plateau habitat.The results showed that the integrated MBR and the front anaerobic SBR process had the best effect on the removal of COD and NH_(3)-N,respectively,and the A^(2)O process had the best effect on the removal of TN and TP at the same time.In addition,the A^(2)O process had the best effect of removing four pollutants simultaneously,and this process treated pollutants at higher influent concentrations,so it was worth considering the A^(2)O process as a mainstream process for municipal wastewater treatment in highland habitats.Both the front anaerobic SBR and integrated oxidation ditch processes achieved 100%of the primary A standard for four pollutants,but the pollutant removal rates were not all optimal,mainly probably because of the low influent concentrations,indicating that these two processes were suitable for treating water with low pollutant concentrations in highland habitats.In conclusion,this comparative evaluation study will provide some assistance in the development of technology applications for urban wastewater treatment processes in highland areas.
