| Abstract: | The process of removing phosphate from industry waste water by magnesium ammonium phosphate crystallization is pres- ented. The main factors which affect the efficiency of phosphate removal are analyzed based on the running data, including reaction and crgstallization time, pH value, concentration of NH4 ~, concentration of Mg2＋, seed crgstal, impurity, total phosphate 10ad and the choosing of material Mg. Based on the analysis, the optimum control conditions are put forward. |
