固定化氮循环细菌修复城市湖泊水体脱氮效果及N_2O排放
Nitrogen removal and N_2O emission from water purification process by immobilized nitrogen cycling bacteria in urban lake
摘要
Abstract
The process of water purification was studied using immobilized nitrogen cycling bacteria, including ammonibacteria, nitrosobacteria, nitrifying bacteria and denitrifying bacteria, which applied and screened for natural water of Lake Jinshan. The result showed that the water quality was improved obviously after running a period of time. Concentrations of NH_4~+-N, NO_2~--N, NO_3~--N and TN declined. NH_4~+-N concentration had reached national Ⅰ class of water quality index. TN concentration had reached Ⅱ class. The N_2O flux of Lake Jiushan increased during three months from April to June, which were 23.5 μg/(m~2·h), 29.521μg/(m~2·h)and59.10μg/(m~2·h) respectively. The experiment has proved that the techniques of immobilized nitrogen cycling bacteria could purify the urban lakes significantly.关键词
