| 摘 要： | 针对近年来我国规模化养殖场迅速发展所带来的严重环境污染,特别是畜禽养殖废水中氨氮污染物所产生的污染,文章采用硝化反应器对其进行处理。首先进行了硝化细菌的培养驯化,然后通过连续运行试验和间歇运行试验,考察氨氮的去除效果和操作参数的影响。试验结果表明:当温度为25℃,pH为6.0~8.0,DO为4.0~6.0 mg/L,HRT为12 h,进水氨氮为200 mg/L时,出水氨氮浓度可以降低到1.0 mg/L左右,氨氮的去除率达到接近100%。

| Abstract: | In recent years the environmental pollutions,Especially NH4+-N pollution in livestock and poultry wastewater are becoming increasingly serious with the rapid development of the large-scale farms in China.NH4+-N removal rate from livestock and poultry farming wastewater was investigated by using a nitrification reactor in this article.Firstly,the nitrifying bacteria was cultivated in the nitrification reactor,and then continuous experiment,the batch experiment were conducted to study the Ammonia removal effe... |
