摘要
测定了干木薯酒精废醪在多种条件下的过滤比阻，结果表明，在过滤温度不低于６０℃时，用饱和石灰乳（石灰２ｇ／Ｌ）复配两性聚丙烯酰胺（ＡＰＡＭ５ｍｇ／Ｌ）或单独用ＡＰＡＭ（１５ｍｇ／Ｌ）作为脱水助滤剂，废醪调质后过滤比阻降至４×１０１１ｍ／ｋｇ以下，适合于真空过滤固液分离。调质药剂费０６元／ｔ。
The specific resistance of waste distillers from alcohol production with dry cassva was measured in various conditions.The results showed that the specific resistance of waste distillers reduced to below 4×1011 m/kg after being coagulated with saturated lime liquor(lime 2g/L)and amphoteric polyacrylamide(APAM 5 mg/L)or only APAM(15 mg/L) at temperature over 60℃,and then waste distillers could be separated by vacuum filtration with chemicals cost of 06 RMB/t.
