无机陶瓷膜处理冷轧乳化液废水

Treatment of Cool Rolling Emulsion with Inorganic Ceramic Membranes

１前言在钢铁厂，为了消除带钢冷轧时产生的变形热，常以乳化液作润滑、冷却剂。乳化液主要由２１０％的矿物油或植物油、乳化剂和水组成。由于乳化液因水分受热蒸发，使盐含量增加、稳定性降低，也会因氧化或细菌作用而变质，所以要连续排出一部分老的乳化液，补充新的乳...

Investigations on treatment of cool rolling emulsion with inorganic ceramic membranes have been conducted. For this system, we found that zirconia membranes have advantages over alumina membranes, that is, the flux through the former was higher than that of the latter. The effects of cross flow velocity, transpressure, temperature have been studied and the operating conditions were optimized. Chemical cleanings have been used to membranes and the methods for membrane regeneration were established. It was shown that the Zirconia ceramic membrane filtration is feasible to the treatment of cool rolling emulsion.
