Description

Technical Field

[0001] The utility model relates to the technical field of chemical wastewater treatment, and more specifically to a chemical wastewater flocculation device. Background Art

[0002] Chemical wastewater refers to wastewater generated during chemical production, primarily including process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site flushing water. This wastewater typically requires treatment before discharge. Chemical wastewater flocculation equipment is used to treat chemical wastewater. This equipment uses physical or chemical methods to aggregate suspended solids and pollutants into larger particles, facilitating subsequent sedimentation and filtration.

[0003] For example, the Chinese patent application number "CN202020111094.0" discloses a coagulation and flocculation device for chemical wastewater treatment; it can effectively prevent the solid flocculant from forming lumps when added to the wastewater, and at the same time prevent the solid flocculant from being insufficiently dissolved and adhering to the rotating shaft, thereby ensuring the flocculation effect on the wastewater.

[0004] After the product is improved, the coagulation and flocculation device for chemical wastewater treatment can put the flocculant into the mixing box for preliminary mixing with the wastewater and then discharge it into the placement cavity of the flocculation box for further mixing. However, the flocculant usually needs to be fully dissolved in clean water and then put into the sewage for flocculation, and the dissolution time of the flocculant is ten to thirty minutes. If the flocculant of the coagulation and flocculation device is mixed with the wastewater without being fully dissolved, it is easy to affect the flocculation effect of the flocculant on the wastewater, which needs to be improved.
