Study on reaction conditions of phosphorus removal from phosphorus containing wastewater using calcium oxide
The phosphorus removal efficiency and economy of four phosphorus removal agents from phosphorus containing wastewater are explored,and the effects of pH,temperature and reaction time on the phosphorus removal rate are studied with calcium oxide used as the phosphorus removal agent.The results show that as the reaction pH increases,the phosphorus removal efficiency of calcium oxide increases,but tends to stabilize when the pH is above 5.05;The higher the initial pH,the better the corresponding phosphorus removal effect;The phosphorus removal efficiency increases continuously with the increase of temperature;The higher the phosphorus concentration,the longer the required reaction time,the higher the corresponding phosphorus removal efficiency.
