Problems solved by technology

[0010] One of the problems to be solved by the present invention is: in the existing fluorine-containing wastewater treatment method, the opening of the dosing pump is adjusted manually, which not only makes it inconvenient to adjust the opening of the dosing pump, cannot realize automatic control, and wastes manpower, but also The opening adjustment time of the dosing pump lags behind, and it is impossible to achieve a good balance between the emission not exceeding the standard and controlling the cost of wastewater treatment

Abstract

The invention provides a fluoride-containing wastewater treatment system and method. The system comprises an agent-feeding device; a measuring device; a control device; the agent-feeding device is used for adding an agent into a primary fluorinion removal device, the primary fluorinion removal device is used for performing primary fluorinion treatment on input fluoride-containing wastewater by using the agent, and discharging the fluoride-containing wastewater; the measuring device is used for measuring the fluorinion concentration of the fluoride-containing wastewater after the primary fluorinion treatment in real time to obtain a primary measuring value; the control device is used for adjusting the amount of the agent added in the primary fluorinion removal device by the agent-feeding device according to the primary measuring value, so as to enable the fluorinion concentration in the fluoride-containing wastewater after the primary fluorinion treatment to reach a target value. The agent amount is automatically adjusted according to the fluorinion concentration in the fluoride-containing wastewater in real time, so that the automatic control on the agent amount is realized, the manpower is saved, the using is more convenient, and the adjustment of the agent amount is not delayed. In addition, good balance between not exceeding a discharge standard and controlling wastewater treatment cost is obtained.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a system and method for treating fluorine-containing wastewater. Background technique [0002] In industrial activities, such as glass production, electroplating production, aluminum and steel refining, and semiconductor component production, etc., a large amount of fluoride-based chemicals are commonly used, which leads to the treatment of fluorine-containing wastewater. In order to prevent the fluoride ions in the fluorine-containing wastewater from polluting the environment and make the discharged industrial wastewater comply with the discharge standards, the industry has carefully studied the relevant treatment procedures to minimize the adverse impact of the discharged wastewater on the environment. [0003] A current method for treating fluorine-containing wastewater includes: introducing fluoride-containing wastewater produced by industrial activities into a r...
