摘要:
设计制作了多孔混凝土水质净化试验装置,对5种不同粗骨料粒径和空隙率的多孔混凝土进行了水质净化性能试验.附着在多孔混凝土表面的生物体的数量可间接地通过溶解氧(DO)的消耗量来检测.多孔混凝土的水质净化性能可通过总磷(TP)和总氮(TN)的去除量进行评价.试验结果表明:多孔混凝土在水中具有富集营养物质,使生物膜附着生长其上的效应; 采用10~20 mm粒径的集料所制备的空隙率为25%的多孔混凝土其水质净化效果最佳.
Abstract:
The results of experiment on water purification properties of porous concrete are reported. Five sizes of coarse aggregate and void ratios were adopted. An equipment for water purification experiment was designed. In the water purification experiment, the amount of organisms attached on the porous concrete surface is indirectly examined by the consumption of the dissolved oxygen(DO). Water purification of the porous concrete is evaluated by the removal amount of the total phosphorus(TP)and total nitrogen(TN). A porous concrete with aggregate size of 10 to 20 mm and void ratio of 25% provides superior ability of water purification. Results from this study show that porous concrete is able to purify water efficiently.
