[0002] Chemical engineering wastewater refers to wastewater containing chemicals and pollutants generated during chemical industrial production. This type of wastewater typically originates from chemical manufacturing, processing, production, and related industrial processes. Chemical engineering wastewater may contain various organic and inorganic compounds, heavy metals, dissolved salts, oils, and other substances.

[0003] A Chinese patent document with authorization announcement number CN211035267U discloses a sewage treatment device for chemical engineering, comprising a treatment box, a cover plate, and a water-conducting sleeve. The treatment box is a hollow cylindrical structure, and the water-conducting sleeve is fixedly connected to the inner bottom of the treatment box. Regarding the above technical solution, the following defects still exist: when treating chemical sewage, precipitants such as iron hydroxide, iron oxide, aluminum oxide, etc. are often added. These precipitants can react with target pollutants in the wastewater to form insoluble precipitates, thereby achieving sewage treatment. However, the chemical precipitates produced by existing devices easily accumulate inside the device, making it difficult to remove the precipitates from the inside of the device, resulting in inconvenience in use.

[0004] For this reason, a sewage treatment device for chemical engineering is proposed. Utility Model Content
