摘要: 为解决低C/N污水的脱氮问题,本实验自行研制开发了一种新型碳聚合物载体。对该载体进行低C/N污水的生物膜脱氮研究,考察了HRT、pH、DO、温度等因素对系统同步硝化反硝化脱氮效果的影响。结果表明:在C/N比为4、pH=8、DO=1mg/L、HRT=6h,T=24℃的条件下,氨氮及总氮的去除率分别可以达到90%和70%。Abstract: In order to solve the problem of removal NH4+-N in the treatment of low C/N ratio wastewater, a new kind of carbon polymer carrier was developed, the removal of NH4+-N by biofilm with the carrier was studied. Factors affected the system of simultaneous nitrification and denitrification, such as HRT, pH, DO and temperature, were investigated. The results indicated that C/N=4, pH=8, DO=1mg/L, HRT=6h, T=24 ℃, the removal rates of NH4+-N and TN were 90% and 70%, respectively.
