摘要
试验采用生物接触氧化法对水体进行处理,以人工模拟的低负荷富营养化水体作为处理对象,将浮动接触氧化床作为主体装置放入水体中进行静态试验,装置的挂膜方式为接种挂膜法,填料为组合填料,进行曝停比为3∶1的间歇曝气。结果表明,通过34 d的处理后,COD、氨氮和总氮的去除率均达到了75%以上,总磷去除率超过50%,对处理低负荷水体有较好效果。本工艺具有使用方便,成本低廉,可重复使用的优点。
The experiment used the biological contact oxidation method to treat water bodies,with artificially simulated low load eutrophic water bodies as the treatment objects.A floating contact oxidation bed was used as the main device and placed in the water body.The film hanging method of the device was inoculation film hanging method,and the filler was a combination filler.Intermittent aeration with an aeration stop ratio of 3∶1 was carried out for aeration.The experimental results showed that after 34 days of treatment,the removal rates of COD,ammonia nitrogen and total nitrogen have both reached over 75%,and the removal rate of total phosphorus has exceeded 50%,which has a good effect on treating low load water bodies.This process has the advantages of convenient use,low cost and reusability.
