摘要
实验采用生物滤池工艺对高氨氮下的亚硝化过程进行了研究,逐步优化运行,结果表明:DO为1.0mg/L,pH值为7.5~8.0,回流比为4时,系统可获得高效稳定的NO2^--N积累。
The short - cut nitrification process under high ammonia concentration condition in a biological aerated filter(BAF) reactor was investigated. The results showed that when DO was 1.0 mg/ L, pH was 7.5 - 8.0, inner circulation ratio of nitration liquid was 4, the rate of accumulation of NO2^- - N was best in the tank reactor.
