| 摘 要： | 采用人工快速渗滤技术净化河道微污染水,渗滤柱内介质分别为不同厚度的火山岩、粗砂、铁矿砂和直径不等的砾石.粗砂滤柱出水水质NH3-N在0.05mg/L以下,TN在lmg/L以下,CODcr在(15～40)mg/L范围,TP在0.1 mg/L以下,叶绿素a在2mg/L以下;砾石滤柱出水水质NH3-N在0.05mg/以下,TN在1.5 mg/L以下,CODcr在35 mg/L左右,TP在0.1mg/L以下,叶绿素a在(1～5)mg/L范围.粗砂滤柱与砾石滤柱对微污染水的去除效率基本相同,但砾石滤柱渗透系数与粗砂滤柱相比.大了2个数量级.

| Abstract: | The slightly-polluted river water was purified by infiltration through the different thickness medium, which is considered as the constructed rapid infiltration treatment system, of volcanic rock, coarse sand, ore sand and various diameters of gravels. The results show that the effluent concentrations of NH3-N, TN, TP and Chlorophyll were less than 0.05 mg/L, 1mg/L, 0.1 mg/L and 2 mg/L respectively and CODCr ranged from 15 mg/L to 40 mg/L after the infiltration of coarse sand. Moreover, the effluent concent... |
