摘要

为解决中国水体富营养化问题

将秸秆碳与硫酸铝作为一种有效吸附水体中总氮、总磷的吸附剂

通过室内模拟试验

采用平衡吸附法

考察了秸秆碳和硫酸铝投加量、pH值、振荡时间、温度、扰动、秸秆碳粒径等不同环境因素条件下对吸附效果的影响。结果表明:在秸秆碳和硫酸铝投加量为0.2 mg/L、振荡时间为120 min的条件下

吸附效果最好

去除率可达80%以上。通过对各因素与秸秆碳、硫酸铝对总氮和总磷的吸附效果分析得知

加入适量的秸秆碳和硫酸铝

可以降低水体中总氮、总磷的含量

吸附效果对温度、振荡时间、pH值变化敏感

这也为解决水体富营养化问题提供了基础依据。

Abstract

In order to solve the problem of eutrophication in China

straw carbon and aluminum sulfate as an effective adsorbent used to absorption of total phosphorus and total nitrogen in water.Through the laboratory simulation test

by equilibrium adsorption method

the author investigated the effect on the adsorption under different environmental factors as the dosage of aluminum sulfate

shaking time

temperature

disturbance

straw carbon size and so on.The results showed that with the dosage of aluminum sulfate and...
