Abstract:

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 120 min, the best adsorption of the removal rate could reach 80% or more. Among different factors, aluminum sulfate on the phosphorus of adsorption analysis indicated that adding an appropriate amount of aluminum sulfate could reduce the phosphorus content in water, the adsorption on temperature, pH, shock time was sensitive. That was to provide a favorable basis for solving the problem of water environment in China.
