Description

technical field

[0001] The invention belongs to the field of sewage treatment, in particular to a chemical dissolving tank for sewage treatment and a method for controlling the dosing thereof. Background technique

[0002] At present, when people treat sewage, it is necessary to add various chemical agents to the sewage as coagulation, flocculation, and coagulant aids for disinfection and sterilization to achieve the purpose of water purification; for some granular solid chemical agents (later Dissolution is generally carried out first, and the concentration of dissolution can be controlled, and then put into the reaction tank according to a certain ratio for coagulation or flocculation or coagulation aid. If the dosing amount of the chemical is not properly controlled during the dissolution process, it will affect the treatment effect of the wastewater in the subsequent reaction tank, and if the dosage is too much, the cost of using the relevant chemical agent will be incre...
