摘 要：
This paper studied the hardness and the best removal effect comparison of processing parameters of six kinds of chemical methods by way of experiment study.The results showed that the lime soda softening method has the best hardness,good operability and good economic benefits.Meanwhile,the optimal process parameters were also discussed.The optimum reaction was pH10.5 and the 100 ml concentrated salt water needed 0.6 g of calcium oxide and0.6 g of sodium carbonate.
