通过电子加速器辐照与生物活性污泥联合处理污水的实验，研究了利用电子加速器强化处理污水生物处理中的一个重要工艺参数-电子加速器强化污水生物处理中的辐照剂量。设置电子加速器辐照剂量为5，20，120，180kGy强化污水生物处理。结果表明，电子加速器强化污水生物处理中辐照最佳剂量为20kGy。对污水的典型主要成分4-氯酚的辐照剂量分别是50mg/ L，20kGy，处理效率已达到100%；并且在以下组合500mg/ L，120kGy；1000mg/ L，180kGy，处理效率达到100%。当电子加速器将难处理的污染物苯环打开，降解成生物易处理的小分子物质时，生物处理的BOD5和COD都明显升高，生物可利用性增强。因此，可采用辐照最佳剂量来提高生物处理污水的效率。得到了辐照技术联合生物处理进行治理污水的方法是最有效的处理污水的方式。高分子难降解的有机物通过联合方法被高效的降解了，目前污水处理存在的主要问题用这种方法能够同时都得到解决。

Through electron-beam irradiation experiment with biological activated sludge wastewater treatment, was studied using electron-beam strengthen treatment of wastewater biological treatment is an important process parameters which is electron-beam strengthen the sewage biological treatment irradiation dose. Set the electron-beam irradiation dose is 1,5,10,20,50 kGy strengthening sewage biological treatment. The results show that the electron-beam strengthens the sewage bological treatment for 20 kGy irradiation dose. Typical of sewage main ingredients of 4 - chlorophenol irradiation dose is 50 mg/L respectively, 20 kGy, treatment efficiency reached 100%; 500 mg/L, 120 kGy; 1000 mg/L, 180 kGy, et al. When electron-beam will be difficult to deal with pollutants benzene ring open, into the biodegradation manageable small molecular substances, biological treatment of BOD5 and COD are significantly increased, enhanced biodegradability. Therefore, the irradiation dose can be used to improve the efficiency of biological wastewater treatment. Got the irradiation technology joint approach to treat biological sewage is the most effective way of sewage. Polymer of refractory organic matter degradation by joint methods are efficient, the main problems existing in current sewage treatment by this method can simultaneously be solved.
