Rectangle, length-width ratio are 3 ~ 10:1, and top is opened wide, internal to inflow direction inclination 10 ~ 20%, so as to sludge settling, total measurement (volume)
Water can be made to stop 10 ~ 50 hours；Wherein boundary is not obviously divided in sludge area and settling zone, natural in pond according to gravity
It separates；
Water is equipped with automatically-controlled door, after settling zone precipitates 10 ~ 50 hours, after natural separation clarification；Settling zone according to height,
Equipped with 3 ~ 10 automatic valves, it is equipped with strainer before automatic valve, is separately turned on according to liquidometer height, is opened when high-order high-order automatic
Valve opens low level automatic valve when low level, so that water slowly flows into clear water zone, to not influence the separating effect of settling zone；
Sludge laydown area is on ground, while slope aspect sludge area, is equipped with strainer with sludge area junction thereon, is worked as sludge
Stacking is that water flow to sludge area by strainer herein；
The super primary sedimentation tank of desulfurization wastewater integrally uses PE to carry out anti-corrosion；
It is convenient for clearing up sludge by mechanical equipment convenient for accumulation in sludge area；
Clear water zone delivery turbidity is less than 1000NTU.
Compared with prior art, of the invention to be advantageous in that:
(1) the super primary sedimentation tank of desulfurization wastewater is added in desulfurization wastewater processing front end, effluent quality is more stable, is less than
1000NTU mitigates back-end processing load, guarantees the normal operation of back-end processing.
(2) sludge area is convenient for accumulation, while being convenient for clearing up sludge by mechanical equipment；
(3) settling zone is equipped with the drainage door set automatically according to height of liquid level, settling zone when draining can be effectively reduced
Separating effect；
(4) water is equipped with automatically-controlled door, chain by liquidometer according to sedimentation effect, after sedimentation basin full water, can close water
Automatically-controlled door is effectively precipitated, and after area's water to be precipitated drains into clear water zone, is then intake；
(5) device is simple, and regulating power is stronger；
(6) process flow is relatively short, reduces investment outlay and operating cost.
