摘    要:水力负荷与湿干比作为人工土层快渗系统的2个重要控制参数,影响系统的处理效果.目前,国内针对三峡库区气候与土壤特征的水力负荷及湿干比研究鲜有报道.为此,论文通过试验,研究了适宜于三峡库区气候和土壤特征的水力负荷和湿干比的相关数据,重点考察了在4种水力负荷与3种湿干比条件下,人工土层快渗系统对生活污水中COD、总氮和总磷去除性能的影响.试验表明,随着气温的升高可以提高系统的湿干比,水力负荷,湿干比的变化对COD,总磷的影响不大,对总氮的影响较大.试验结果可为人工土层快渗系统在三峡库区推广应用提供依据.

关 键 词:人工土层快渗系统  生活污水  水力负荷  湿干比

Abstract:The hydraulic loading and wet/dry(W/D) ratio,which are two important indexes in the constructed rapid infiltration,can affect the removal effect.Presently,the domestic experimental reports about the hydraulic loading and(W/D) ratio aiming at the Three-Gorges Reservoir Region is rather scarce.This article studies some pertinent hydraulic loadings and W/D ratios suitable for the Region.The authors emphatically research the effect of CRI treating COD,TN and TP in the sewage under four hydraulic loadings and three different W/D ratios.It is suggested that when the temperature is ascending,the W/D ratio can be risen to some extent.The variations of loading and ratio can affect the COD,TP removal effect a little,but affect the TN removal effect much.The experimental conclusions can provide evidence to the application of constructed rapid infiltration in the Three-Gorges Reservoir Region.
Keywords:constructed rapid infiltration  sewage  hydraulic loading  wet/dry ratio
