过氧化钙对磷的去除效果研究
Study on Effect of Calcium Oxide on Phosphorus Removal
摘要
Abstract
In different conditions,the effect of calcium on the removal of phosphorus from black water was studied.The results show that the temperature on the removal rate of phosphate is related to the initial concentration of phosphorus.When the initial concentration is more than 100 mg/L, temperature and the removal are rate-negatively correlated,when the initial concentration is less than 100 mg/L,both were positively correlated.The effect of calcium oxide on the removal efficiency of phosphate was greatly affected by pH.The initial pH and reaction pH were studied respectively. When the initial pH was neutral,phosphorus removal effect is best,the partial acid or alkali is not conducive to removal phosphorus,by maintaining reaction system pH can be found that the higher the alkaline,the better of the phosphorus removal effect,when the pH is 3 the phosphorus removal effect is zero.It was found that calcium oxide and phosphate were produced by the reaction products that is tricalcium phosphate.关键词
