The axis angle in two apertures in above-mentioned each reaction lattice 8 is 90 degree.Because the aperture is staggered a pond body interior opposite angle, the aperture jet action is stronger, and the current order produces swirling flow in each reaction lattice 8, and the suspended substance flocculation is quickened, and increases precipitation capacity.
Above-mentioned reaction zone, reaction lattice 8 are rectangle.Be easy to arrange, save the floor space of total system.
A plurality of orifice area in the above-mentioned reaction zone increase successively along water (flow) direction.Because of orifice area progressively increases, thereby current gradient from big to small, helps flocculation.
The structure of above-mentioned settling region is the structure of tube settler 9.Be beneficial to precipitation.
Also be connected with coal water equalizing tank 1 before the above-mentioned water inlet pipe.To contain the coal Waste Water Centralized and regulate water quality and quantity, and carry out preliminary sedimentation to coal water equalizing tank 1.
Between above-mentioned coal water equalizing tank 1 and the coal water comprehensive treating process device 3 static mixer 2 can also be set.In static mixer 2, can add flocculation agent, than directly adding by pipeline conveniently, and be convenient to control.
Above-mentioned water outlet 11 can also be connected with reuse pool by strainer." clear liquid " sent by tube settler 9 enters sends into the reuse pool reuse after strainer filters.
Above-mentioned strainer adopts the quartz sand filtration device.After filtering, suspended substance≤10mg/L in the water.
Above-mentioned mud discharging mouth 7 is connected with the coal slime dewatering device.The coal slime that post precipitation produces reclaims use after centrifuge dehydration.
Compared with prior art, the utility model has the advantages that:
1, good waste water treatment effect: contain that the suspended substance removal rate is up to 99.5% in the coal waste water after using the utility model to handle, its suspended substance mean value only is 10mg/L, and the pH value is on average about 7.8, and all the other indexs all reach or are lower than discharging standards; 2, realize waste water recycling: this treatment process has not only solved the fuel-burning power plant and has contained coal standard wastewater discharge problem, has also realized waste water recycling, has saved the consumption of power plant's service water; 3, realize the coal slime direct reuse:, realize energy second stage employ by the recyclable thin buckwheat coal of the utility model; 4, reduce production costs: service life of equipment is long, has reduced cost for wastewater treatment, has also just reduced the whole production cost; 5, total system can adopt the PLC automatic control system, can reach the unattended duty fully automatic operation.
