摘要
某住宅小区污水产生量为100m^(3)/d,配套建设污水处理站,设计出水水质《城市污水再生利用城市杂用水水质》GB/T18920中绿化用水的水质要求及《城镇污水处理厂污染物排放标准》GB18918的相关标准,处理采用成熟稳定的生物接触氧化工艺,处理出水用于学校冲厕所、小区杂用等。年污染物减排量COD、BOD5、SS分别为12.78t/a、7.67t/a及7.67 t/a,每年可节约水资源36500m^(3),年可节约水资源费10.58万元,做到经济效益、环境效益和社会效益的统一。
Sewage production of a residential district is 100m^(3)/d,supporting the construction of sewage treatment stations,designed effluent water qualityGB/T18920green water,flushing water quality requirements and GB18918 related standards,The treatment adopts mature and stable biological contact oxidation process,and the treated effluent is used for school toilet flushing and community miscellaneous use.The annual pollutant emission reduction rate of COD,BOD5 and SS is 12.78 t/a,7.67 t/a and 7.67 t/a respectively,which can save 36500m3of water resources and 105800 yuan of water resources cost per year,so as to achieve the integration of economic benefit,environmental benefit and social benefit.
