沉砂池装置
By introducing an agitator and a material distribution trough into the grit chamber, the inlet angle and distribution of wastewater are adjusted, solving the problem that existing grit chambers cannot effectively separate organic matter from sand. This achieves uniformity and effectiveness in wastewater treatment and protects subsequent equipment and processes.

AI Technical Summary
Existing grit chamber devices cannot effectively separate organic matter attached to sand in sandy wastewater, leading to wear and tear on pumps, blockage of pipe networks, and interference with the biological treatment process.
A sedimentation tank device including an agitator and a feeding trough was designed. The feeding position and water inlet angle of the feeding trough are adjusted by a linear motor assembly and an angle adjustment device. Combined with the design of the agitator and the jet pipe, the wastewater is evenly distributed and the organic matter attached to the sand is effectively separated.
It achieves uniform distribution and effective separation of sand-containing wastewater, protects subsequent treatment equipment, prevents wear and blockage, and ensures the smooth operation of the biochemical treatment process.
