小区高效污水处理与回用工艺设计

Design for efficient treating and recovering sewage within a small region

采用厌氧 -兼性 -好氧工艺处理小区污水 ,并应用于世外桃源小区污水处理工程实践 .构筑物设计为地埋式 .工程运行实践表明 ,该工艺处理效率较高 ,出水水质可以达到国家《污水综合排放标准》 (GB 8978-96)一级标准 ;运行稳定 ,运行一年多来 ,尚未出现水质不达标现象 .该工艺动力消耗小 ,运行成本平均为 0 0 6元 /m3左右 ;占地面积较小 ;采用的二氧化氯消毒法安全 ,效果较好 。

Anaerobic-facultative-aerobic process is adopted to treat small region sewage and applied to Utopia region sewage treatment engineering practice.The reactors are designed underground. The running practice shows that the degree of treatment is high so that the effluent quality can meet the first standards in The National Sewage Discharge Standards .After running over one year, there is no test result under the standard. The equipment consumes little power.The running cost is 0 06 yuan/m 3 and occupies less space. It takes ClO 2 as disinfectant,which is safe and effective. The effluent quality can meet the demand of recovering. The anaerobic-facultative-aerobic process is suitable for our country's present situation and can be generalized.
