摘要
对人工快渗系统CRI进行了模拟实验。研究结果表明,CRI对COD、氨氮有较好的去除效果;在有机负荷0.2-0.6 kg COD/（m^3.d）、水力负荷周期1-2.5 d和湿干比2∶1-1∶3的适宜工艺条件下,COD去除率达到70%-90%,氨氮去除率达到90%;增大水力负荷周期和减小湿干比都有利于COD的去除。
Simulation experiment is made, and the results show that the removal rate of COD is 70% to 90% under the organic loading of 0.2-0. 6 kg COD/（m^3 . d） and the hydraulic loading cycle 1-2.5 d with the ratio of the flooding period to the drying period being 2 ： 1-1 ： 3. The removal rate of NH3N reaches 90%. Increasing the hydraulic loading cycle and decreasing the ratio of the flooding period to the drying period are favorable for removal of COD.
