摘 要:随着能源经济的发展,城市人口的增长以及水环境面临的复杂形势,高浓度氨氮废水直接排放进入水体容易引发海水赤潮和湖泊水发生水华现象,而且高浓度氨氮废水中含有的亚硝酸盐容易使人体致癌、致病、致畸。为进一步遏制水体富营养化,解决高浓度氨氮废水带来的环境问题,我国将氨氮纳入主要污染物总量控制指标。以相关生物反应器为手段,以畜禽废水为处理对象,将复合菌剂与固定化材料相结合,考查固定化复合菌在不同pH、不同温度、不同初始浓度的影响下对高浓度氨氮废水的处理效果。设置pH为8,温度为30℃,初始浓度为400 mg/L时为最佳条件,该条件可满足畜禽废水出水氨氮标准。With the development of energy economy,the growth of urban population and the complex situation of water en-vironment,the direct discharge of wastewater with high concentrations of ammonia and nitrogen into water bodies can easily cause red tides in seawater and water wars in lakes.Moreover,the nitrite contained in wastewater with high concentration of ammonia and nitrogen can easily cause cancer,disease and malformation in human body.In order to further curb eutrophica-tion of water bodies and solve the environmental problems caused by high concentration of ammonia nitrogen wastewater,the state has included ammonia nitrogen into the total control index of major pollutants.This experiment takes the relevant bioreactor as the means,takes livestock and poultry wastewater as the treatment object,combines the composite bacteria agent with the immobilized material,and investigates the treatment effect of the immobilized composite bacteria on the high concentration ammonia nitrogen wastewater under the influence of different pH,different temperature and different initial concentration.The optimal conditions were pH 8,temperature 30℃ and initial concentration 400 mg/L,which met the am-monia nitrogen standard of livestock and poultry wastewater.
