| 摘 要： | 在多孔混凝土中添加高炉矿渣制成掺高炉矿渣多孔混凝土(BSPC),与普通多孔混凝土相比较:BSPC对酸性水中TP、浊度、Mn和Fe的平均去除率随高炉矿渣掺量的增加而提升。其中掺20g高炉矿渣BSPC的对TP、浊度、Mn和Fe的平均去除率较普通多孔混凝土分别提高了0.77%,3.48%,4.73%和8.67%;掺40g高炉矿渣BSPC较普通多孔混凝土去除率提升更显著,分别为4.11%、7.93%、8.18%和12.57%;三种不同多孔混凝土出水pH都达到GB20426-2006的排放要求。

| Abstract: | We used Alkaline blast-furnace slag as admixture for porous concrete to make blast furnace slag porous concrete(BSPC).Compared with ordinary porous concrete,BSPC increased in the average removal rate of turbidity,total phosphorus ,Fe and Mn in acid water with the amount of blast furnace slag increasing. The BSPC with 20 g blast furnace slag increased by 0.77%,3.48%,4.73% and 8.67%. The BSPC with 40g blast furnace slag was more improved than BSPC with 20 g blast furnace slag,which were7.93%,4.11%,12.57% and 8.18% respectively. The effluent of three different porous concrete met the requirements of GB20426-2006 for pH emission. |
