【摘要】 检测和分析了无极紫外光消毒器中前后中水中大肠杆菌群数、大肠杆菌群的复活和再生现象、消毒副产物的生成及有机物的去除情况。结果表明:流量小于350L/h时,消毒后的大肠杆菌群杀菌率达到99.9%以上,消毒后的水质均满足水质标准;在可见光照射下,消毒后水样中大肠菌群数的增长速度比在避光保存时快,在流量较小时,消毒后水样中的大肠菌群数在可见光照射下和避光保存时增长都比较缓慢;无极紫外光可以降解水体中的微量有机物,且消毒后基本上不产生THMs和HAAs等消毒副产物。更多还原

【Abstract】 E.coli,revival and rebirth of e.coli,the generation of disinfection by-products and elimination of organic matter in water are checked and analyzed before and after disinfection.The results show that when the flux is less than 350 L/h,microwave electrodeless ultraviolet irradiation can achieve an inactivation rate of 99.9% after disinfection,disinfected water satisfies the standard of water;when visible light irradiates in the disinfecting water,when the flux is small,the disinfecting water of E.coli is slower;electrodeless ultraviolet light can decompose the water of atom of organic matter,and it does not bring THMs and HAAs and so on disinfection outgrowth after disinfection.更多还原
