摘要
研究了电子束不同辐照剂量对城市污水中污染物含量的影响.研究结果表明:电子束辐照对城市污水中大肠杆菌的灭除有显著效果,当辐照剂量达到4 kGy时,大肠菌群下降5个数量级.电子束辐照对城市污水中的化学需氧量(COD)有一定去除作用,当剂量达到20 kGy后,COD含量变化平缓,其最高去除率达到了63.5%.电子束辐照对污水中的氨氮有一定的去除作用,当辐照剂量达到120 kGy时去除率达到47.8%.电子束辐照对污水的pH值没有明显作用.
This paper researches the effect of electron beam irradiation dose on the content of pollutants in municipal sewage. The results show that electron beam irradiation can significantly eliminate eolibacillus in municipal sewage. When the dose was 4 kGy, the colibacillus dropped down five orders of magnitude. Electron beam irradiation can remove the chemical oxygen demand （COD） of the city sewage to a certain degree. When the dose exceeded 20 kGy, the COD content changed a little. The highest removal efficiency achieved 63.5%. Electron beam irradiation can also remove the NH3-N of the sewage to a certain degree. When the dose was 120 kGy, the removal efficiency achieved 47.8%. Electron beam irradiation has no significant effect on pH of the sewage.
