Problems solved by technology

[0002] The sludge concentration of biochemical process is about 2500-3500mg / L. If the sludge concentration is too high, it will affect the sedimentation effect of the subsequent secondary sedimentation tank. The existing magnetic coagulation sedimentation treatment effect is limited, and the waste of magnetic powder is serious
