污水处理中紫外消毒效果的研究

紫外消毒技术相对于氯化法消毒,能够快速、有效地去除污水中粪大肠杆菌,操作简单方面,无副产物生成,对周围环境和人员安全可靠,在中国许多污水处理厂都已取代氯化法消毒并广泛应用。阐述了紫外消毒和微生物光复活现象的原理,并通过大量试验来研究紫外消毒技术去除粪大肠杆菌的效果,及经紫外消毒后出水中粪大肠杆菌光复活现象对紫外消毒效果的影响,提出可采用出水避光排放、增加紫外照射剂量、延长照射时间等方法来控制微生物光复活现象。

Wastewater Treatment Study on the Effect of UV Disinfection

UV disinfection technology in relation to chlorination disinfection,can be quickly and efficiently remove the effluent fecal E.coli,simple operation,the no-product generation,on the surrounding environment and personnel safe and reliable,in many of our sewage treatment plants have been replaced by chlorine Disinfection method and widely used.UV disinfection and described the phenomenon of micro-organisms,then the principle of liberation,and through a large number of tests to study the UV disinfection technology to remove the effect of fecal E.coli,and by UV disinfected effluent fecal E.coli photoreactivation phenomenon on the UV disinfection effect of proposed dark discharge effluent can be used to increase the dose of UV radiation to extend the exposure time and other methods to control the phenomenon of micro-organisms photoreactivation.
