硫酸铝对富营养化水体中磷的去除效应及影响因素

为了解决中国水体富营养化问题，本研究将硫酸铝作为一种有效吸附水体中总磷的吸附剂，通过试验室模拟试验，采用平衡吸附法，考察了硫酸铝投加量、pH值、震荡时间、温度、扰动等不同环境因素条件下对吸附效果的影响。结果表明：在硫酸铝投加量为0.2 mg/L、pH值为7、震荡时间为120 min的条件下，吸附效果最好，去除率可达80%以上。通过对各因素与硫酸铝对磷的吸附效果分析得知，加入适量的硫酸铝，可以降低水体中总磷的含量，吸附效果对温度、震荡时间、pH值变化敏感，这也为中国解决水体富营养化问题提供了基础依据。

Removal of Phosphorus from Eutrophic Water by Aluminum Sulfate and the Influencing Factors

In order to solve the problem of eutrophication in China, aluminum sulfate as an effective adsorbent used to absorption of total phosphorus 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, pH, shaking time, temperature, disturbance and so on. The results showed that with the dosage of aluminum sulfate was 0.2 mg/L, the pH was 7, the shock time was 1...
