医院污水净化消毒方法的研究

A Study on Method of Purification and Disinfection in Hopspital Sewage

采用SL系列污水净化装置（实验型）配合新型混凝消毒剂（PAM－PAC）在广州铁路中心医院进行污水处理研究，结果COD、BOD、SS去除率分别达86．7％、927％和83．6％，使这三项指标从原分别超过广州污水排放标准34倍、4．8倍和0．7倍降至标准以下，从而减少消毒剂的使用量，医院每年可节约25．0万元。以广东地区铁路医疗机构排污水统计，则可减少外排污染物391．8T／年，节约资金76．9万元／年，显示良好的社会效益和经济效益。

SL series sewage purified device (experimental type) with new tw of disinfectant flocculant (PAM -PAC ) were used to treat hospital sewage in Guangrhou Railway Central Hospital. Clearance rate of COD, B0D lSS were 86.7%, 92 .7%, and 83 .6% resPeCtively. These three indices which were 3 .4, 4. 8 and O.7 timesof Guangzhou Sewage Drainage StandaId resPectively, met the standard after treatInnt. Because of the reduchonof the disinfectant amount, about 25O thousand yuan Per year would be saved in the hospital. The amount ofsewage wotild be decreased 39l. 8 tons per year and 769 thousand yuan could be saved per year in wholexailway medical organization in Guangdong.
