AI Technical Summary

Technical Problem

Existing inclined plate flocculation sedimentation equipment suffers from problems such as impurity adhesion leading to blockage of water flow channels, incomplete sedimentation, and reduced equipment efficiency when treating recalcitrant petrochemical wastewater, and cannot meet the long-term, stable, and efficient pretreatment requirements.

Method used

It adopts a stirring and mixing structure and a dynamically adjustable inclined plate structure. Through mixing by the stirring shaft, gear and rack meshing transmission, and baffle plate cooperation, it can automatically clear the gap between the inclined plates, ensuring smooth water flow and efficient sedimentation of impurities.

Benefits of technology

It achieves efficient flocculation and sedimentation of wastewater, automatically clears the gaps between inclined plates, prevents material blockage, continuously ensures purification efficiency and smooth treatment, reduces operation and maintenance costs, and meets the needs of long-term continuous and stable wastewater treatment.
