应用带洗涤功能的隔膜压滤机，通过滤布选型，研究了水洗对从浸锌渣中回收水溶性锌的可行性。结果表明：透气率为80 L/（m2· s）的单丝滤布在过滤性能和成饼均匀性上更适合热酸浸出浆料的过滤和洗涤；清水洗涤40 min ，可将渣中水溶锌质量分数由4．40％降至0．101％，水溶锌回收率达97．5％，而且整个滤饼的洗涤均匀性非常好。
應用帶洗滌功能的隔膜壓濾機，通過濾佈選型，研究瞭水洗對從浸鋅渣中迴收水溶性鋅的可行性。結果錶明：透氣率為80 L/（m2· s）的單絲濾佈在過濾性能和成餅均勻性上更適閤熱痠浸齣漿料的過濾和洗滌；清水洗滌40 min ，可將渣中水溶鋅質量分數由4．40％降至0．101％，水溶鋅迴收率達97．5％，而且整箇濾餅的洗滌均勻性非常好。

By the membrane filter press with washing function ,the feasibility of recovery water-soluble zinc from leaching residue using clean water was investigated .Results indicate that the monofilament filter cloth with 80 L/(m2 · s) is more suitable for hot acid leaching pulp for the uniformity and filter performance of cake .The content of water-soluble zinc can reduce from 4 .40% to 0 .101% and the recovery of water-soluble zinc can reach 97 .5% using clean water to wash 40 min .Besides ,the homogeneity of the cake after washing is quite well .
