Description
Summary:In this paper, PAC was prepared from kaolin. The control experiment was carried out by controlling a single variable to find the most suitable conditions for processing simulation. The main reference indicators were pretreatment ratio, calcination temperature, calcination time, acid dissolution time, and acid dissolution ratio, acid. Specific parameters such as solution temperature, and then complete data to process polyaluminum chloride products with a certain degree of alkalinity. On this basis, this paper uses the experimentally prepared polyaluminum chloride product for coagulation experiments to test the treatment of P element in wastewater by PAC.
