It is possible to improve the efficiency of physics, chemistry, and operation management in three areas:
1. Improving physical structure
1) Increased slanted plate/slanted pipe: Larger slant surface, shorter slant diameter, improved solid-liquid separation efficiency.
2) Improved water flow equipment: Perforated holes for sills, subhole rectification, and other technologies for evenly distributed water flow, short flow relief, and uniform flow selection.
3) Control flow speed: Overall average horizontal flow speed control control 10-25mm/s, extended descending time.
2. Chemical aids
1) Add flocculants (such as PAC, PAM) : Promote the aggregation of fine particles into large flocs, accelerates the descending speed.
2) Fine sand circulation and sand processing: Continuous fine sand production, crystal nucleus enhancement, solid body density, dredging speed up to 20-40m/h, removal rate up to 80%-95%.
3, Operational management
1) Periodic sludge removal: Prevent sludge accumulation and sludge efficiency.
2) Holding temperature determination: Temperature reduction and flow control, constant temperature for the required time.
3) Complete control: Periodic monitoring, flow rate information, mixing ratio, and time adjustment.
The above-mentioned measures can be implemented to achieve floating object removal rate of 80%-95%, anti-dropping capacity of more than 30%, and annual drop rate of 10%-30%.
