摘要
设计了一种新型三相内循环生物流化反应器,对其硝化特性进行了试验研究。试验结果表明,水力停留时间(HRT)为4 h、溶解氧(DO)质量浓度为3 mg/L、温度(t)在25～30℃,单位CODCr有机负荷为4 kg/(m3.d)左右时,氨氮(NH4+-N)去除效果最佳,去除率可达80%以上。
Three-phase inter-circulating biological fluidized reactor was designed and its characteristic of nitrification was studied. The results showed that the removal efficiency of NH4^＋-N was optimal, above 80 %, when HRT was 4 h, DO was 3 mg/L, temperature was 25 - 30 ℃ and CODcr load per unit was 4 kg/（m^3.d）.
