摘要
使用微波/紫外/臭氧(MW/UV/O3)工艺对经二级处理后的城市生活污水进行消毒。探讨了消毒方式和进水水质对消毒效果的影响。结果表明,在相同的处理时间,MW/UV/O3对水样中大肠杆菌的杀菌率大于MW/UV和O3,MW/UV/O3处理240 s后出水水质的大肠杆菌残菌数达到国家标准GB/T18920-2002。进水水质对MW/UV/O3杀菌效果有影响,进水浊度过大会使杀菌率大幅度下降。
MW/UV/O3 was applided to sterilize the discharge of two-stage treated municipal wastewater.The effect of different sterilization mode and inflow water quality was studied.The results showed that the sterilization efficiency of MW/UV/O3 was better than that of MW/UV or O3 when same treatment time was taken.After processing 240 s by MW/UV/O3,the E.coli bacteria number in water met the national standard GB/T 18920-2002.Inflow water quality might influence the sterilization effect as high turbidity could reduce the sterilization rate dramatically.
