Low-temperature domestication of an iron and manganese oxidizing bacteria
One superior iron and manganese bacteria were separated from the stable operation of porcelain granular BAF filters of removing iron, manganese and ammonia. The bacteria was domesticated at low temperature. By analyzing the sample water containing iron and manganese in the role of iron and manganese bacteria which was not domesticated and domesticated at different temperature, observing the Iron and manganese concentration with time going on, studying the bacterias removal of iron and manganese property and the domesticated effect. Studies show that: the selected bacteria with 1％ bacterial liquid at proper temperature within 48h ,the removal rate of iron and manganese was 75％ and 35％ respectively;After domesticated at low temperature, the removal rate of the iron and manganese domesticated bacteria at 10℃ was improved 0.4 and 2 times more than the before domesticated;The iron and manganese domesticated bacteria at 10℃ did not grow at 4℃,but the bacterias removal rate was better than the bacteria cultured at 30℃,and the iron removal rate was improved from 23％ to 35％,the manganese removal rate was improved from 5％ to 11％.
