Abstract

Recently years many large lakes are eutrophic or in serious state of eutrophication. And most eutrophic water from phosphorus control action is the amount of input, so how to effectively reduce the phosphorus content of sewage has become noticeable within the field of environmental protection issues. In the present study natural zeolite as material and finding that the original zeolite adsorption effect only is 8%-18% . Due to the removal effect, choose modified zeolite, through to the acid and alkali salt for respectively , then insure that using 20% MgCl2 best of static test examines the pH , temperature, adsorption time , the effects of the removal rate could reach 70%-85% . The last time, dosing quantity for the orthogonal experiment research, determine the optimum condition of the adsorption is at 25 , 160min, 5g respectively, and the removal efficiency can reach 82%.
