【摘要】：采用微污染河水作为模拟雨水和地面径流,经免烧结成型的硅砂滤水砖渗滤装置处理后,检测滤前和滤后的水质变化。结果表明,经过透水砖渗滤作用,对浊度、NH+4-N和TP的平均去除率分别为58.7%、12.8%和21.1%;由于硅酸盐的析出导致p H值稍微增大;CODMn浓度在开始的几次过滤中有少量增长,之后随着过滤次数的增加而下降;硅砂滤水砖对溶解性荧光有机物中类蛋白物质浓度的影响不大,但类腐殖质物质浓度稍有增加。
[Abstract]:The micro polluted river water as simulated rainwater and surface runoff, the sand filter water infiltration treatment device without sintering brick after the change of water quality detection before and after filtering the filter. The results show that after filtration of water permeable brick, the average removal of turbidity, NH+4-N and TP were 58.7%, 12.8% and 21.1%; the P H value of Portland resulted in the precipitation slightly increased; the concentration of CODMn had a slight increase in several times at the beginning of the filter, then decreased with increasing filtration times; sand filter water brick have little effect on the dissolved organic matter in the fluorescent protein like substances concentration, but the concentration of humic like material increased slightly.
