【摘要】 文章采用ND-90型超高交联吸附树脂吸附处理采矿塌陷区废水。原废水COD质量浓度为200￣230mg·L-1,经沉淀-树脂吸附法处理,处理量20BV,吸附流出液COD质量浓度为40～50mg·L-1,COD去除率≥80.23%,树脂经过碱液脱附后可重复利用且运行稳定。该处理工艺投资少、操作简便,为解决采矿塌陷区水体修复问题提供了一种新的方法。更多还原

【Abstract】 The wastewater produced in subsidence of mining, containing ρ(COD) 200 ～ 230 mg·L-1, is treated with polymeric adsorbent ND-90. It is shown that the effective treatment amount of is 20 BV, the concentration of COD in the effluent after adsorption is 40~ 50 mg·L-1, and the removal efficiency of COD excesses 80.23% by neutralization, precipitation and adsorption on resin.更多还原
