本文报导了酸法提纯硅藻土和废酸综合利用的研究工作．文中介绍了高浓度废酸循环利用和利用废酸生产硅藻土水净化剂、硫酸钙的方法．由于废酸综合利用．不仅可避免大量废酸排放造成的环境污染，而且降低了酸法提纯硅藻土的成本．
This paper reports the research work on the comprehensive utilization of diatomite and waste acid by acid method. This article describes the high concentration of waste acid recycling and use of waste acid production of diatomite water purification agent, calcium sulfate method. Due to the comprehensive utilization of waste acid. Not only to avoid a large number of waste acid emissions caused by environmental pollution, but also reduces the cost of acid purification of diatomite.
