[0002] Cold rolling wastewater refers to wastewater generated during the production of cold-rolled steel, mainly including cold rolling lubricants, cooling water, cold rolling fluid, etc. The wastewater contains a large amount of suspended solids, grease, heavy metals and other harmful substances, and has the characteristics of high concentration, high temperature, high pH, ​​etc. Cold rolling wastewater causes serious pollution to the environment and needs to be treated to meet the emission standards. Common treatment methods include sedimentation, filtration, biological treatment, etc.

[0003] The patent with publication number CN 216584529 U discloses a steel cold rolling wastewater reuse pretreatment softening treatment device, which includes a box-shaped pretreatment tank with openings at the top, bottom and side bottoms, a base is sealed at the bottom of the pretreatment tank, a support frame is installed on the top of the base, and a motor is installed on the side of the pretreatment tank. The device can efficiently and quickly filter out suspended matter after the dosing reaction, thereby improving the pretreatment efficiency of the steel cold rolling wastewater. However, the device has the problem of directly introducing the steel cold rolling wastewater into the pretreatment tank, adding an appropriate amount of softening agent, and then precipitating calcium and magnesium plasma in the wastewater. However, both the filter box and the filter screen in the device are directly welded to the pretreatment tank or the filter box, which makes it difficult to clean out the filtered sediment left in the pretreatment tank, thereby affecting the subsequent wastewater treatment work. For this reason, a steel cold rolling wastewater reuse pretreatment softening treatment device is proposed to solve the problem that the existing wastewater softening device is difficult to quickly discharge the sediment.
