intake Outlet under guide shell be equipped with umbrella-shaped baffle, be uniformly distributed waste water in pond, then the entire section along pond slowly rises.It is outstanding Floating object is settled under the effect of gravity in bottom of pond taper sludge bucket, and primary water is discharged to coagulation from the overflow weir around the upper end of pond Sludge in mudpan is discharged in biochemistry pool by sedimentation basin by air lift, supplements sludge concentration, and excess sludge is drained into sludge In concentration basin.By adding alkali, PAM and ferrous sulfate in coagulative precipitation tank, starting blender uniform stirring reaction goes to remove water In SS and reduce COD;Inclined plate packing blocked by blower air lift and is deposited on the sludge of bottom and is discharged into sludge concentration tank, on Clear liquid is entered by pipeline self in the clear water reserviors of the advanced treatment unit of active carbon filtering, is thrown into charcoal canister by pump Filtering, standard discharge.Sludge in sludge concentration tank is thrown into sludge tank by pump, is delivered to filter press through pneumatic diaphragm pump Inside it is compressed into mud cake outward transport.
Embodiment 2
Experimental applications example: the efficient process system of pharmaceutical industry production of raw medicine organic wastewater.
Certain northern drugmaker, high concentrated organic wastewater discharge amount about 50t/d, about 150 t/d of low concentration wastewater discharge amount, Waste water processing station, design scale 200m are established using the utility model processing system3/ d, wherein high concentrated organic wastewater After pretreatment of High Concentration Wastewater unit, dosing unit, triple effect evaporation unit process, converge in low concentration wastewater Unified Set into Enter the advanced treatment unit processing of biochemical treatment unit, sludge press filtration unit and active carbon filtering, final water quality reaching standard discharge is dirty Mud filters pressing outward transport.
The efficient process system water quality indicator such as table 1,2 of pharmaceutical industry production of raw medicine organic wastewater:
The main influent quality index of table 1. summarizes
The main effluent quality index of table 2. summarizes
To sum up, after this system, COD removal rate can reach 96%, BOD removal rate, and to can reach 86%, SS removal rate reachable To 54%, for ammonia nitrogen removal frank up to 82%, high concentrated organic wastewater and the low concentration for meeting the discharge of drugmaker's production of raw medicine are useless The efficient process system of water.
Although the utility model is described above in conjunction with attached drawing, the utility model is not limited to above-mentioned Specific embodiment, the above mentioned embodiment is only schematical, rather than restrictive, the ordinary skill of this field Personnel are under the enlightenment of the utility model, in the case where not departing from the utility model aims, can also make many variations, this It belongs within the protection of the utility model a bit.
