摘要

对硝基酚(PNP)是一种有毒难降解有机物

是生产农药、医药、炸药、合成染料的重要中间产物

其污染控制与消除是国内外研究的热点与难点。土壤含水层处理(SAT)系统具有低耗高效、操作简单等优点

既是当前应用广泛的污水处理系统

也是地下水人工回灌的基本水质处理技术。通过建立一维土柱实验模拟SAT系统

研究非生物与生物强化条件下对硝基酚在SAT系统中的迁移规律及去除效果

并探讨SAT对地下水环境的潜在二次污染风险。研究表明:两种条件下的SAT系统中

PNP浓度在从下至上迁移过程中均逐渐降低;非生物条件下

SAT通过吸附作用去除PNP

土壤层有效处理厚度为60 cm

粗砂、中粗砂、细砂3种介质的去除率为10%左右;生物强化条件下

SAT通过吸附与生物降解共同去除PNP

去除率提升至88.5%。

Abstract

p-Nitrophenol (PNP)

a toxic and recalcitrant organic compound

has been widely used as an intermediate for preparing phosphororganic insecticides

medications

explosives and synthetic dyes. Control and removal of PNP is always a research focus. Soil aquifer treatment (SAT) system is a widely used wastewater treatment system with better efficiency and low cost

which is also used for artificial aquifer recharge. The present study investigated PNP removal in the SAT system under abiotic and bio-augmentation conditions using 1D columns. PNP was removed well in both cases. Soil adsorption was the main mechanism under abiotic condition. The depth of soil for effective treatment was 60 cm

and removal rates reached 10% for coarse

medium-coarse and fine sand columns. Under bio-augmentation condition

PNP removal rate with addtional bio-degradation increased to 88.5%.
