Description

Technical Field

[0001] The utility model relates to the technical field of regulating tanks, in particular to a regulating tank for chemical wastewater. Background Art

[0002] During the discharge process of industrial wastewater, as the production conditions change, there is uneven water quality and unstable water quantity. In order to make the treatment process work normally and not be affected by changes in the peak flow or peak concentration of wastewater, it is necessary to use a regulating tank to adjust the water quality and water quantity before wastewater treatment.

[0003] After searching, Chinese patent CN214808790U was found and announced, which is a regulating tank for industrial sewage treatment. The rectangular frame is placed obliquely, so the garbage blocked by the wire mesh will slide down along the wire mesh to the cavity of the collection box for storage, reducing the garbage falling into the bottom of the regulating tank body. The cover is opened, and the second spring is restored to generate an upward impact force, pushing the connecting block along the limit column to drive the collection box to move up. Since the garbage in the regulating tank body is concentrated in the collection box, it is only necessary to dig out the garbage in the collection box when cleaning, shortening the cleaning time. At the same time, the rotating rod will push the slider during the upward movement of the collection box Sliding along the slide bar pushes one end of the rectangular frame upward to a horizontal state, making it convenient for the staff to clean or replace the wire mesh. It can be seen that the patent realizes the convenience of discharging the garbage blocked by the wire mesh and cleaning and replacing the wire mesh. As a regulating tank, it is necessary to treat the pollutants in the chemical wastewater, so that they are combined with the precipitant to form a precipitate and discharged, so as to meet the requirements of the emission standards. Since the patent does not realize the treatment of chemical wastewater, in order to add an appropriate amount of precipitant according to the amount of chemical wastewater flowing into the regulating tank, a regulating tank for chemical wastewater is proposed.
