摘要
目的 对医院污水进行深处理 ,并在医院污水站、病区、门诊大楼、绿化地等处建立再生水的循环利用系统 (中水道 ) ,使再生水重复利用达到节水。方法 医院污水一级处理加氯化消毒 ,中水道建设。结果 处理后水中悬浮物为 8~16mg L、化学需氧量 2 5~ 31mg L、5d生化需氧量 14~ 16mg L、细菌总数 4 9× 10 2 ~ 5 9× 10 2 个 ml、粪大肠菌群数 <2 0个 L、余氯 0 0 2~ 0 4 2mg L ,理化指标达到综合循环再利用要求标准。结论 医院污水处理达标后再生水的重复应用有利于节水和环保。
Objective: To construct the reclamation water distribution network after sewage conventional treatment in the hospital sewage treatment.Methods: After first-stage treatment of hospital wastewater advanced treatment was carried out to the wastewater volume of hospital sewage and pollution:for saving water resource and environmental protection.Result The water quality reached the hygienic index for reclamation and reuse,The results showed the suspended particle concentration(8~16 mg/L),COD(25~31 mg/L),BOD(14~16 mg/L),total count of bacteria(4.9×10 2~5.9×10 2个/ml),and total coliforms(<20个/L),residual chlorine(0.02~0.42 mg/L) after wastewater treatment.Conclusion The water quality after treatmeat can be improved greatly,and can be used for reclamation.
