Research of Producing Liquid Polyaluminum Chloride from Aluminum-Containing Tail Liquid and Its Industrial Application
The development of liquid polyaluminum chloride for sewage treatment plant by using aluminum-containing tail liquid as a by-product produced in the process of comprehensive utilization of waste catalyst was introduced.The process can effectively utilize the aluminum-containing tail liquid with low added value,and the product quality is stable,reaching the national standard,and the preparation process is reliable and the production cost is low.After small-scale test and industrial scale-up,the water purification effect of industrial oily sewage samples was evaluated.The results showed that the parameters and appearance of the purified water met the purification requirements of industrial sewage,and the sewage purification effect of small-scale test and industrial products was equal to or higher than that of reference agent,which had a good application prospect.
