The device has the following characteristics: the sedimentation pool is orderly connected with a water storage pool, an air floatation device and a return water pool through a pipeline; the upper part of the air floatation device is connected with the sludge pool through a pipeline; and the sludge pool is connected with a concentrating belt type filter press through a pipeline. The device has the advantages of low cost, wastewater zero-drainage and environment protection.
Description
Technical field
The utility model belongs to waste disposal plant, is specifically related to a kind of paper making wastewater zero discharge device.
Background technology
The production of Corrugating Base Paper is to be raw material to reclaim domestic waste and old Corrugated Box, by a series of Waste Paper Handling technology, produces qualified Corrugating Base Paper.Principal pollutant in the waste water are SS and COD that fiber fines and mineral filler, impurity etc. form.The method of wastewater treatment of existing enterprise is generally the processing mode of materialization, comprises that water collecting basin, oblique net drag for oar pond, settling tank, chemicals dosing plant, sludge sump.The sewage of slip house is earlier by spacing grid or mechanical grille, enter water collecting basin behind the bulk buoyant dirt in the interception sewage, enter oblique net and drag for the oar pond, adopt the oblique net of 60-80 order or drag for fiber fines, impurity in the pulp grinder filtered wastewater, add flocculation agent after entering settling tank, further remove part SS and COD by precipitation, this kind wastewater treatment equipment is simple in structure, part that can be removed SS and COD, but processed waste water SS and COD are still higher, both not reached the reuse requirement can not 100% reuse, does not reach national specified discharge standard again; The enterprise that also has adopts materialization to add biochemical method and disposes of sewage, this kind wastewater treatment complex manufacturing, and processed waste water SS and COD reach national specified discharge standard, but the cost of investment height, the operational management difficulty is big.
Summary of the invention
The purpose of this utility model provides the paper making wastewater zero discharge device of a kind of waste water 100% recycle, environmental protection.
The utility model is achieved through the following technical solutions:
It is a kind of paper making wastewater zero discharge device, comprise that grid, water collecting basin, oblique net drag for oar pond, settling tank, sludge sump, it is characterized in that settling tank passes through pipeline and is connected with the pond with storage pond, air-floating apparatus, backwater successively, described air-floating apparatus top is by pipeline and sludge sump, and described sludge sump is connected with concentrated belt filter press by pipeline.
Described air-floating apparatus is the super efficiency shallow air flotation machine.Utilize the micropore gas distribution, produce micro-bubble, the small suspended matter in the waste water is attached on the bubble as carrier, form the flotation body, utilize the buoyance lift effect of bubble, rise to the water surface, by collecting the purpose that foam on the water surface or scum silica frost reach separating impurity, purify liquid waste.Foam or the scum silica frost collected enter sludge sump by pipeline, and the water of handling the back cleaning enters backwater and uses the pond.
The strainer of described concentrated belt filter press is arranged for S shape.Roll shaft and strainer contact area are big, and the squeezing time is long, and the suffered pressure of mud relaxes.The water ratio of dehydrated sludge is low, generally is controlled in 75%, becomes the cake rate higher more than 90%, and treatment effect is better.
The utlity model has that cost is low, the advantage of wastewater zero discharge, environmental protection.Water in the settling tank enters and stores the pond through the laggard excess of imports effect of redeposition shallow air-floatation machine, after handling, air supporting reaches the requirement of reuse water, enter backwater and use the pond, be pumped to slip house, as the slurry dilution water by reuse water, high-low pressure rinse water, mechanical seal water etc. recycle, when accomplishing wastewater zero discharge, reduced the consumption of slip house water of productive use, not only environmental protection but also reduced production cost, the utility model adds biochemical process with respect to materialization and handles waste water, less investment, cost is low.
Description of drawings
Accompanying drawing is a synoptic diagram of the present utility model.
As shown in FIG.: 1 grid, 2 water collecting basins, 3 oblique nets drag for the oar pond, 4 settling tanks, 5 sludge sumps, 6 store the pond, 7 super efficiency shallow air flotation machines, 8 backwater are used the pond, and 9 concentrate the belt compressor.
Embodiment
As shown in drawings: grid 1, water collecting basin 2, tiltedly net drags for oar pond 3, settling tank 4, sludge sump 5, stores pond 6, super efficiency shallow air flotation machine 7, backwater connect by pipeline successively with pond 8, gas super efficiency shallow air flotation machine 7 tops are connected with sludge sump 5 by pipeline, sludge sump 5 is connected with concentrated belt filter press 9 by pipeline, is equipped with the pump group on the described pipeline.
When the utility model used, waste water was 10-20mm grid 1 by the lattice distance at first, and the bulk in the interception waste water suspends or the buoyant dirt, prevents block pumps group or pipeline.Waste water through grid 1 enters water collecting basin 2, after mixing, carry out the storage homogeneous of waste water, part waste water is as the dilution water reuse Workshop Production of operations such as pulping in the water collecting basin 2, residue waste water rises to oblique net by pump and drags for stock tank 3 places, tiltedly net adopts the fiber fines in the 100 order net filtration water, fiber fines in the water and big particle and impurity are held back by oblique net, carry to processing back, workshop fully recovering by the pump group, clean relatively waste water by oblique net enters that to add with polymerize aluminum chloride and polyacrylamide before the settling tank 4 be the flocculation agent of main component, make the fiber fines wadding in the water poly-agglomerating, waste water is promoted to settling tank 4 through pipeline and carries out the center water distribution, waste water is through after about 4.5 hours residence time, under the assist process of polymerize aluminum chloride and polyacrylamide, part SS and silt particle etc. be deposited at the bottom of the pond through Scraping device be collected into settling tank 4 central bottom most position by tubes rows to sludge sump 5, primary water by around weir plate evenly overflow to enter and store pond 6, shallow air-floatation machine 7 is imitated in the laggard excess of imports of precipitation process.Super efficiency shallow air flotation machine 7 utilizes the micropore gas distribution, produce micro-bubble as carrier, small suspended matter in the waste water is attached on the bubble, form the buoyance lift effect that the flotation body utilizes bubble, rise to the water surface, foam on the water surface or scum silica frost enter sludge sump 5 by pipeline, handle the clean waste water in back and enter reuse pool 8, be transported to the workshop by the pump group, as the slurry dilution water, high-low pressure rinse water, mechanical seal water etc. recycles.Be promoted to concentrated belt compressor 9 after the mud that sludge sump is 5 li mixes and carry out concentration.The strainer of pre-concentration belt filter press 9 arranges that for S shape roll shaft and strainer contact area are big, and the squeezing time is long, and the suffered pressure of mud relaxes.The water ratio of dehydrated sludge is low, generally is controlled in 75%, becomes the cake rate higher more than 90%, and treatment effect is better.
