利用电子束辐照与粉煤灰吸附两种方法对城市污水处理进行了研究，结果表明：先进行辐照处理然后再进行粉煤灰吸附有助于城市污水中的CODCr、BOD5和氨氮等污染物的去除，显示出一定的协同效应；电子束辐照对污水中的大肠菌群灭杀效果显著，而粉煤灰吸附能有效去除污水中的总磷，二者的结合能够实现其优势互补，当辐照剂量20 kGy、灰水比1∶20时综合处理效果能够达到城市污水排放一级B标准。

In this paper , a combined treatment method for urban sewage is researched by utilizing the electron beam irradiation and the adsorption of fly ash .The results show that the combined treatment ( firstly irradiation of electron beam, then adsorption of fly ash ) makes for the removal of such pollutants in urban sewage as COD Cr , BOD5 and Ammonia&nitrogen , showing synergy;the irradiation of electron beam may significantly kill the colibacillus in ur-ban sewage , while the adsorption of fly ash may effectively remove the total phosphorus from sewage .The combina-tion of the two methods may realize the mutual replenishment of advantages .When the irradiation dose is 20 kGy and the ash-water ratio is 1 ∶20, the integrated treatment effect may reach Grade I level B of urban sewage dis-charge.
