|
摘要
[目的]研究TBO+反硝化池组合工艺冬季运行效果。[方法]通过加热风机对深渗滤系统进行充氧,保证微生物有足够的溶解氧和温度,从而形成TBO工艺(保湿生物膜曝气技术),并与反硝化池组合形成新的组合工艺处理农村生活污水。[结果]COD去除效率提升了12%,平均去除率达到85.0%;NH_3-N去除效率提升了10%左右,平均去除率达到79.8%。[结论]该组合工艺抗冲击负荷能力强、氮磷去除效率高、自动化程度高、节能环保,并适应安徽省皖北地区气候环境。
[Objective] The research aimed to study the winter running effect of TBO + denitrification pool combination process.[Method]The oxygen in the deep infiltration system was oxygenated by the heating fan to ensure that the microorganisms had enough dissolved oxygen and temperature,a TBO process( moisturizing biofilm aeration technology) was thus formed and combined with a denitrification tank to form a new combined process for the treatment of rural domestic sewage.[Result]The COD removal efficiency increased by 12%,the average removal rate reached 85.0%,the NH_3-N removal efficiency increased by about 10%,and the average removal rate reached 79.8%.[Conclusion]The combined technology has strong anti-shock load capability,high nitrogen and phosphorus removal efficiency,high degree of automation,energy conservation and environmental protection,and adapts to the climate and environment of northern Anhui Province.
