Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a purification device for industrial wastewater discharge. Background Art

[0002] Sewage treatment devices are common equipment in our lives, mainly used for domestic or industrial sewage treatment. Since there are many impurities in sewage, the sewage treatment device generally needs to perform regular purification on the bottom of the sewage treatment tank after a period of use, so that the sewage treatment device can operate better. In the existing sewage treatment process, special flocculants are usually added to carry out preliminary sedimentation of pollutants, which can reduce or eliminate the precipitation stability and polymerization stability of dispersed particles in petrochemical sewage, so that the dispersed particles can coagulate and flocculate into aggregates, which is convenient for filtering and removing solid pollutants in the form of dispersed particles in chemical sewage. At the same time, flocculants can also effectively remove microorganisms and pathogens in water, and can remove emulsified oil, chroma, heavy metal ions and some other pollutants in sewage.

[0003] However, in the existing flocculation process, the flocculant cannot be fully mixed with the sewage water, resulting in low flocculation efficiency.

[0004] The existing Chinese patent with the announcement number CN218435169U discloses an industrial wastewater purification device, including: a coagulation tank, on which a water inlet and a water outlet are arranged relatively, and the water inlet is higher than the water outlet; a stirring part, the stirring part is arranged in the coagulation tank, and the stirring part is in a mesh to cover the water space of the coagulation tank; a driving device, the driving device includes a driving mechanism and a transmission mechanism, the driving mechanism drives and connects the transmission mechanism; the driving mechanism is fixedly arranged on the wall of the coagulation tank; one end of the transmission mechanism is connected to the driving mechanism, and the other end of the transmission mechanism is connected to the fixed part of the stirring part. The stirring part can be set as a mesh structure with almost the same area as the water space, and it can be moved up and down by the driving device, so that the water in the water space can be completely mixed, and the coagulation efficiency is improved after the flocculant is added.

[0005] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device stirs up and down through a mesh structure that is almost the same area as the water space, and the mesh structure will relatively block the dredging operation at the bottom of the pool, which needs to be improved; therefore, a purification device for industrial wastewater discharge is proposed to address the above-mentioned problems.
