The invention discloses a treatment and reuse system and a treatment and reuse method for high-arsenic and high-fluorine polluted acid, which belong to the technical field of comprehensive utilization of metallurgical resources. The unit, the CO 2 hardness reduction unit, and the deep desalination unit are connected in sequence. The acid sludge produced in the treatment process is sold under pressure filtration, the neutralized slag is shipped and stored, and the lime emulsion is recycled; Effectively improve the use efficiency of neutralizing agents and the efficiency of neutralization and impurity removal, and significantly reduce the production cost; the method is simple to operate, and can ensure the effective treatment of polluted acid, and finally all the effluent is returned to the production system for targeted utilization, which provides a guarantee for the zero discharge of water in the enterprise. Has good social and economic benefits. |
