我国硫酸工业废水处理技术综述

Overview of waste water treatment technologies in China's sulphuric acid industry

介绍了我国硫酸工业废水情况及废水处理工艺技术,重点论述了石灰法、石灰-铁盐法、硫化法和三段逆流石灰法等中和处理工艺,以及污泥处理工艺。根据废水水质和出水要求,可选择不同废水处理工艺技术,实现废水达标排放。

Waste water treatment status and treatment technologies in China＇s sulphuric acid industry are introduced with the emphasis on some neutralizing treatment processes including lime and lime-ferric salt process, sulfide process and three-stage back flow lime process, and sludge treatment processes. According to different waste water quality and effluent requirement, different waste water treatment processes can be chosen to guarantee effluent to be up to the discharge standard.
