活性炭处理污水中农药残留的研究进展
|
摘要
随着城市的迅速发展,污水问题日趋严重。污水处理问题一直是我国亟待解决的重要环境问题。按国家要求,企业应优先利用处理后的再生水,这就对污水处理技术有了更高的要求。污水里含有的残留农药结构复杂不易处理。总结了活性炭的分类,分析了温度、pH值和用量等因素对污水中农药吸附率的影响,并解释了吸附机理。对该领域今后发展面临的问题进行了论述。
With the rapid development of city, the problem of sewage is becoming more and more serious. Sewage treatment has always been an important environmental problem to be solved in China. According to the requirements of the state, enterprises should give priority to the use of treat-ed reclaimed water, which has a higher demand for sewage treatment technology. The residual pesticide contained in sewage is complex and difficult to handle. The classification of activated carbon was summarized, the influence of temperature, pH value and dosage on the adsorption rate of pesti-cides in sewage were analyzed, and the adsorption mechanism was explained. The future development problems in this field were also discussed.
