摘　　要：原有生活污水处理厂提标改造前采用氧化沟生物处理工艺,由于进水水量水质不均匀,出水无法稳定达到标准。兴隆庄煤矿生活污水处理厂提标改造项目,提出了采用调节池预处理+兼氧池+氧化沟+二沉池+深度处理工艺,同时根据污水厂处理设施实际情况,增加了硝化回流工艺,出水能完全满足排放要求。Before upgrading the original domestic sewage treatment plant,the oxidation ditch biological treatment process was adopted.Due to the uneven quality of the influent water,the effluent could not reach the standard stably.Xinglongzhuang Coal Mine domestic sewage treatment plant upgrading and reconstruction project,proposed the use of regulating tank pretreatment+facultative oxygen tank+oxidation ditch+secondary sedimentation tank+advanced treatment process.At the same time,according to the actual situation of sewage treatment facilities,the nitrification reflux process was added,and the effluent can fully meet the discharge requirements.
