降解水源氨氮的高效菌株及组合筛选

Combination screening of high effective strains to decompose ammonium nitrogen in light pollute water

通过实验证实 ,无论采用何种来源的硝化菌、亚硝化菌、芽孢杆菌、假单孢菌接种于广州市西村水厂水源水中 ,均可降解氨氮 ,其去除率为 40 .0 %～ 94.5 % ,在降解氨氮过程中 ,硝酸盐和亚硝酸盐的含量有的增加 ,有的减少 ,但增加的均未超过GB3838-88规定标准 。

Experiments have been done to make sure that 3 or 4 kinds of bacteria available from anywhere had been inoculated in the water from Xicun water plant and found out that all of them could remove NH\-4\|N effectively with the rate ranges from 40% to 94 5%. During the decomposition to NH\-3\|N, the content of nitrate and nitrite in some treatment increased and decreased in others, however, in all of treatments it never exceeded the enviromental quality standard for surface water(GB3838-88).
