摘要
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COD Cr、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 CODcr, 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.
