Paper industry uses timber, straw, reed, rag etc. to be raw material, isolates Mierocrystalline cellulose through the High Temperature High Pressure boiling, makes paper pulp.In process of production, the non-cellulose of discharging at last in the raw material partly becomes black liquid.Contain xylogen, Mierocrystalline cellulose, VFA etc. in the black liquor, frowziness, contaminative is very strong.Therefore, need deal carefully with paper waste, the waste water aerobic biologic treating technique that utilizes microorganism in the water to handle waste water extensively applies to various wastewater treatments.Traditional aerobe treatment technology comprises activated sludge process, biomembrance process etc., but common activated sludge process, biomembrance process processing efficiency are low, occupation area of equipment is big, the aeration aerating power consumption generally accounts for 60～70% of total electricity consumption, and capacity usage ratio has only percentum, and energy expenditure is big.Though the internal circulation gas-lift type recirculation reactor can improve the capacity usage ratio in the wastewater treatment process effectively, but for reactor and settling tank Round Sump, though can not establish mud backflow facility, but exist carrier current to become estranged the subregion because of forming the problem that anaerobic zone produces the mud come-up, reactor and settling tank branch are built then and are built a settling tank and increase mud backflow facility more again.
The utility model content
The utility model is exactly in order to solve above-mentioned the deficiencies in the prior art part, and a kind of paper waste biochemical processing device is provided.This equipment combines the air lift type recirculation reactor and intakes continuously, the characteristics of the extended aeration sequencing batch active sludge of cycle draining, the technological process of gas stripping type recirculation reactor is intake continuously, handle at same reaction unit, thereby improved paper waste biochemical treatment efficient.
The technical solution of the utility model is:
Technological process for the treatment of papermaking device of the present utility model comprises by the outer cylinder body of stent support and is built in outer cylinder body and by the fixedly connected inner barrel of back up pad, the bottom of described inner barrel is provided with diffusion sprayer and filtering net, described outer cylinder body top is provided with level switch, the import of described diffusion sprayer is connected on the water circulating pump by the circulating water inlet road, the certain altitude place, middle part of described outer cylinder body is provided with water outlet and is connected in by circulating water outlet pipe road and recirculated water valve and carries out effluent cycle on the water circulating pump and flow, the water-in of described water circulating pump also connects the sewage water inlet pipe road and flows into sewage, the bottom of described inner barrel is provided with the mud relief outlet and is connected in the spoil disposal valve by the mud discharge line discharges mud, the top of described outer cylinder body is provided with water outlet and is connected in the discharge of water purification valve by the water purification outlet conduit and purifies waste water, and the certain altitude place, middle part of described inner barrel is provided with inlet mouth and is connected in pneumatic pump by air intake pipe and air door and pumps into air.
Further, described spoil disposal valve also connects mud extraction pipeline discharge mud.
Further, described water purification valve also connects an outlet conduit and discharges and to purify waste water.
The utility model compared with prior art, the advantage that has is: compare with common activated sludge process and gas stripping type aerobic treatment, the utility model does not need to establish secondary sedimentation basins, primary sedimentation pond, mud backflow and mud refluxing unit, has significantly reduced the initial cost and the working cost of reactor.And the utility model is to handle at same reaction unit, thereby has improved paper waste biochemical treatment efficient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
Technological process for the treatment of papermaking device of the present utility model comprises the outer cylinder body 1 that is supported by support 6 and is built in outer cylinder body 1 and by the fixedly connected inner barrel 2 of back up pad 3, the bottom of described inner barrel 2 is provided with diffusion sprayer 4 and filtering net 5, described outer cylinder body 1 top is provided with level switch 11, the import of described diffusion sprayer 4 is connected on the water circulating pump 803 by circulating water inlet road 801, the certain altitude place, middle part of described outer cylinder body 1 is provided with water outlet and is connected in by circulating water outlet pipe road 805 and recirculated water valve 804 and carries out effluent cycle on the water circulating pump 803 and flow, the water-in of described water circulating pump 803 also connects sewage water inlet pipe road 802 and flows into sewage, the bottom of described inner barrel 2 is provided with the mud relief outlet and is connected in spoil disposal valve 902 by mud discharge line 901 discharges mud, the top of described outer cylinder body 1 is provided with water outlet and is connected in 1002 discharges of water purification valve by water purification outlet conduit 1001 and purifies waste water, and the certain altitude place, middle part of described inner barrel 2 is provided with inlet mouth and is connected in pneumatic pump 703 by air intake pipe 701 and air door 702 and pumps into air.Described spoil disposal valve 902 also connects a mud extraction pipeline 903 and discharges mud.Described water purification valve 1002 also connects an outlet conduit 1003 discharges and purifies waste water.
The utility model combines facilities such as preliminary sedimentation tank, second pond, sludge digestion tank, control by robot control system(RCS), the intravital sewage of technological process for the treatment of papermaking device tube is criticized formula ground carry out aeration, precipitate and strain water, constantly experiencing aerobic-anoxic-anaerobism cycle change procedure.In the working cycle, continuously enter reaction inner barrel 2 through the diffusion sprayer 4 of the waste water after the scalping through being installed in the cylindrical shell bottom, at aeration phase, by opening air door 702 and pneumatic pump 703 pumps into a large amount of air, current and the acting in conjunction of air-flow ground make the shower nozzle below form high speed turbulent shear district again, make the refinement of bubble height and the homodisperse that are sucked, utilize the pressure head dissolved oxygen simultaneously, greatly improved the utilization ratio of oxygen in the air, the combined sewage that is rich in dissolved oxygen is got back to the bottom by the district that descends after guide shell reaches reactor head, form circulation, jet on shearing again, operation so moves in circles.Water level rises to the design top water-level with water inlet gradually by the lowest water level of design.After system stopped aeration, system entered the sedimentation and drawing stage, at precipitate phase, made the active sludge flocculation under the immobilized condition, and mud sinks with the form of regional subsidence, thereby formed sludge concentration is higher.Mud also filters through filtering net 5, after precipitation finishes, purifies waste water by water purification outlet conduit 1001 and 1002 discharges of water purification valve, and makes water level return to the design lowest water level.Be untreated the completely successive ground warp circulating water outlet pipe of waste water road 805, recirculated water valve 804 and water circulating pump 803 comes back in the reacting cylinder body and handles.
