摘　　要：本文提出在用硫酸铝处理燃煤电厂灰水[2]的同时，加入硫酸氢钠，以提高降低灰水pH值效果。配水试验及黄石电厂灰水的静态研究试验表明：效果明显，灰水的pH值可降低到7～8。It is stUdied in the paper to treat ash sluicing water in coal - fired power Plants by aluminium sulphate with sodium bisulfate dosing for its PH reduction. laboratory test and static test of ash sluicing water taken from Huangshi power plant show that such treatment can achieve an obvious result with pH reduction to 7～8.
