Abstract

针对宁南山区典型饮水型集雨系统窖水的水质特征研究薄弱的问题,通过对水窖进行实地监测,对比研
究了不同集雨系统水窖在贮存雨水约180 d 后水质基本达到稳定状态时的水质特征。结果表明,①在集雨面同为
庭院的条件下,混合窖(水泥砂浆抹面,窖底铺胶泥)的水质总体优于水泥窖;以混凝土公路面为集雨面的胶泥窖水
质较差。②3 种集雨系统中窖水的总磷(TP)量均超标,其中公路面与胶泥窖组合形式下的总磷(TP)量超标较严
重,达到66.7%。③3 种典型集雨系统窖水中的细菌总数均严重超标,且只有公路集雨形式下的胶泥窖水中的大肠
杆菌超标。集雨面污染对窖水水质的影响较大,公路收集的雨水水质较差;地区水窖应因地制宜,采用混合窖要优
于纯水泥窖。

Other Abstract

Through indoor simulated infiltration experiment, the permeability reduction when cement filtrated into
different soil matrix under different infiltration water quality were researched. The results showed that: ①
whether tap water or sewage infiltration, cement slurry always had certain permeability-reducing effect as infiltrating
into different soil matrix. When the content of soil clay and silt was higher, the permeability-reducing effect
was worse; ② the infiltration-reducing effect of postponed water feeding way was superior to the effect of instant
water supply way under different infiltration water quality;③Under two kinds of water supply mode, sewage
infiltration reduceded soil infiltration rate. The permeability-reducing effect of sewage infiltration was inferior
to the effect of tap water infiltration. And the difference was more apparent under delay water supply mode.
