Since industrial wastewater often contains a variety of toxic and harmful substances that pose a great threat to the environment, it can only be discharged after appropriate purification treatment.

[0003] Currently, flocculation and sedimentation methods are used for wastewater treatment. Flocculants are added to the wastewater to cause impurities in the wastewater to condense into flocs, which are then filtered to separate the flocs from water to achieve wastewater purification. However, traditional flocculation and sedimentation and filtration operations are carried out in sedimentation tanks and filtration tanks respectively, which affects work efficiency. In addition, this set of treatment equipment occupies a large space and has a high construction cost, making it unsuitable for small factories to treat wastewater.

[0004] Therefore, there is an urgent need to provide an industrial wastewater treatment device that integrates sedimentation and filtration treatment. Utility Model Content
