摘要
设计一种以互联网数据调查为基础,修建可渗透反应墙来修复城市河流污染水体生态环境。可渗透反应墙的设计主要分为7步:首先,利用互联网调查城市河流污染情况,形成数据基础,然后根据该情况选取反应墙结构、确定墙体安装位置、规模、走向、渗透系数以及活性材料,最终完成可渗透反应墙的构建。结果表明,与传统城市河流污染水体生态环境修复方法相比,经过可渗透反应墙修复后的城市河流,水中各种污染物质(COD、BOD、NH^+_4、氨、磷、汞、Mn、Cd、其它)的浓度分别减少了105 mg/L^(-1)、70.5 mg/L^(-1)、50.2 mg/L^(-1)、59.8 mg/L^(-1)、38.5 mg/L^(-1)、3.1 mg/L^(-1)、1.9 mg/L^(-1)、2.4 mg/L^(-1)、1.1 mg/L^(-1),说明了该方法的有效性。
Permeable reaction wall was designed to repair the polluted water ecological environment of urban rivers based on the Internet data survey. The design of permeable reactive wall is divided into 7 steps: first, using the Internet to investigate the pollution of urban rivers, form the data base, then select the structure of the reaction wall, determine the location of the wall, the scale, the direction, the permeability coefficient and the active material, and finally complete the construction of the permeable reactive wall. The results showed that the concentrations of various pollutants (COD, BOD, NH + 4, ammonia, phosphorus, mercury, Mn, Cd, and other) were reduced by 105 mg/L^-1 , 70.5 mg/L^-1 , 50.2 mg/L^-1 , 59.8 mg/L^-1 , 38.5, respectively, compared with the traditional urban river polluted water environment restoration methods. Mg/L^-1 , 3.1 mg/L^-1 , 1.9 mg/L^-1 , 2.4 mg/L^-1 , 1.1 mg/L^-1 , which illustrate the effectiveness of the method.
