Description

Technical Field

[0001] The utility model relates to the technical field of chemical wastewater treatment, and more specifically, to anti-precipitation chemical wastewater treatment equipment. Background Art

[0002] Chemical wastewater is a general term for all types of wastewater generated during chemical production. It comes from a wide range of sources, has complex composition, and experiences significant variability in both quality and quantity. Chemical wastewater contains a variety of organic and inorganic pollutants. Organic pollutants include organic acids and esters, most of which are toxic and difficult to biodegrade. Inorganic pollutants include heavy metal ions, which pose serious risks to the environment and human health.

[0003] Chemical wastewater treatment requires the addition of coagulants and stirring to aggregate the colloidal particles and fine suspended matter in the wastewater into larger flocs. However, during the treatment process, some impurities or solid particulate matter will precipitate, preventing some pollutants in the wastewater from fully contacting the coagulant. These impurities and pollutants can enter subsequent treatment units, affecting subsequent treatment results and even causing the final effluent water quality to substandard. In view of this, we propose a chemical wastewater treatment equipment that prevents precipitation. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide an anti-sedimentation chemical wastewater treatment equipment to solve the technical problem that some impurities or solid particulate matter will precipitate in the current wastewater treatment process, resulting in some pollutants in the wastewater cannot fully contact with the coagulant.

A filter plate is provided in the drain pipe, and the filter plate is flush with the inner wall of the bottom end of the treatment tank.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model designs an anti-sinking plate structure. When multiple anti-sinking plates move, the shovel plate part of the anti-sinking plate can shovel up impurities at the bottom of the treatment tank. The first arc part and the second arc part of the anti-sinking plate can make the anti-sinking plate exert an upward force on the industrial wastewater, so that the impurities at the bottom of the treatment tank move upward, which can effectively prevent the pollutants in the wastewater from settling, and make the pollutants in the industrial wastewater fully contact with the coagulant, thereby ensuring the industrial wastewater treatment effect, and solving the problem that some impurities or solid particulate matter will precipitate in the current wastewater treatment process, resulting in some pollutants in the wastewater not being able to fully contact with the coagulant.

[0012] 2. The utility model also designs an arc-shaped plate structure. When multiple anti-sinking plates move, the sliding ball can slide in the limit groove. Under the action of multiple arc-shaped plates, the sliding ball can continuously rise and fall, so that the front end of the anti-sinking plate can be swung upward, further pushing the pollutants settled at the bottom of the treatment tank to move upward, which can effectively prevent the sedimentation of pollutants in the wastewater.
