Pretreatment part of printing and dyeing wastewater treatment equipment

Pretreatment part of printing and dyeing sewage treatment equipment ①Grid well. Grate well dimensions are. Assume that there is one coarse and one fine grid each, the grid gap of the front coarse grid is, and the grid gap of the rear fine grid is. Angle tilt, manual cleaning.
②Adjusting pool. Volume is, underground type, hydraulic retention time. There is a perforated tube inside for aeration and stirring to prevent sedimentation, and at the same time it plays the role of pre-aeration and removes parts. ?
③Vertical flow sedimentation tank. The volume is , the upward flow rate is , and a vortex reactor is installed in the middle. The mud collection method is gravity mud discharge. Strengthening the primary treatment by adding chemicals (iron-based coagulant) before the pump can remove ~ and greatly reduce the chroma. Equipped with a Chinese intelligent online monitor developed by our institute to control the value at ~, a stable dosing removal effect can be obtained to ensure that the subsequent biochemical process is in good condition.
