含汞废水深度处理技术在电石法PVC汞减排体系中的应用

Application of an advanced treatment technique for the reduction of mercury emission in production of PVC by calcium carbide method

介绍了一种沉淀法与过滤法(过滤采用膜材料或特殊活性炭)相结合处理含汞废水的新技术,可以将含汞废水中的汞质量浓度处理到0.005 mg/L以下,较好地解决了含汞废水对环境造成污染的问题,这对于企业健康可持续发展具有非常重要的意义。

A new technique, which combined precipitation method with filtration method, for the treatment of mercury-containing waste water was introduced. By the technique the contents of mercury in mercury-containing waste water could be below 0. 005 mg/L, and the environmental pollution problem of mercury-containing waste water was solved satisfactorily, which was of great significance to the healthy and sustainable development of enterprise.
