Experimental Study on the Treatment of Eutrophic Water by Floating Contact Oxidation Bed
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.
