摘　　要：本文通过在CRI系统现场系统中湿干比,水力负荷周期和增加通气管对复氧效果的研究,发现在湿干比1∶6时,CRI系统对与复氧有关的指标CODCr、NH3-N的去除率较高,系统复氧效果较好;通过缩短系统水力负荷周期,加大系统淹水、落干频率,可以加大系统的复氧量,提高系统的复氧效率,CODCr和NH3-N的去除效果均有所提高;增加通气管对CRI系统复氧效果不明显。A field test using Constructed Rapid Infiltration System （CRI） was conducted to study the effect of factors such as wet/dry （W/D） ratio, hydraulic loading cycle and increasing aeration pipes on reaeration. It found that when W/D ratio was 1： 6, the removal rates of CODer and NH3-N were high that meant a good effect of reaeration for the CRI system. The operations such as decreasing hydraulic loading cycle and increasing the frequency of flooding and dry alternation would increase the reaeration amount consequently improve the reaeration rate as well as the removal rates of CODcr and NH3-N. However, there was no significant effect for reaeration to increase aeration pipes.
