医院污水、生活污水净化处理的研究

STUDY ON PURIFICATION TREATMENT OF SEWAGE OF HOSPITAL AND DOMESTIC

目的 :了解生物滤池和臭氧消毒对医院污水和生活水的净化效果。方法 :于污水处理前二级生物滤池处理后及臭氧消毒后分别取水样测定悬浮物、 CODcr、 BOD5 、氨氮及粪大肠菌群 ,观察不同处理方法处理污水后上述指标浓度的变化情况。结果 :经生物滤池处理后医院污水及生活污水中悬浮物、 CODcr、 BOD5 、氨氮的去除率分别为 99.61%～ 99.99% ,93 .45%～ 99.45% ,98.63 %～ 99.80 % ,98.63 %～ 99.80 %。经臭氧消毒后 ,水中粪大肠菌群的去除率为 99.99%。结论 :生物滤池结合臭氧消毒的方法对污水有很好的净化效果。

Objective:To learn effect of purification of s ewage of hospital and do mestic by biological filtration and ozone disinfection Methods:The samples were respectively taken before and after sewage was treated by two-stage biological filtration and ozone disinfection And the sludge saspended particles, CODcr,BOD 5,ammon ia, N and fecal coliform were determined Results:After biological filtration treatment, the removal rare of sludge suspended particles, CODcr、BOD 5, and ammonia, N was 99 61%~99 99%,93 45%~99 45%,98 63%~99 80% and 99 99% respectively After ozone disinfection, the removal rate of fecal coliforn was 99% Conclusion: The purification technology of using biological filtration and ozone disinfectio n was very effective for treatment of sewage of hospital and domestic, which cou ld be widely applied to treat sewage
