摘　　要：电石法生产氯乙烯工艺中,针对5%～10%过量氯化氢的净化,若采用常规净化方法,既污染环境又造成大量的浪费.本文介绍的净化工艺,不但大大降低含汞废酸水对环境的污染,而且还能减少氯乙烯的损失并将废酸水变废为宝.In the production of PVC by calcium carbide process, excess hydgoren chloride is adsorbed to form hydrochloric acid by upstream and cycle water, and it also reduced the pollution of waste water containing Hg and loss of PVC.

关 键 词：净化 逆流部分循环 水洗塔 泡沫塔 氯化氢 含汞废酸水
