Abstract
The utility model relates to a wastewater treatment device made of corrugated paper, which comprises a water collection tank, a mesh screen filtering device, a primary sedimentation tank, a hydrolysis acidification tank and a secondary sedimentation tank connected in sequence. The upper part of the water collection tank is provided with a grille. The wastewater treatment device is characterized in that an anaerobic reactor and an aerobic aeration tank are arranged between the hydrolysis acidification tank and the secondary sedimentation tank, and all the components are communicated through pumps and pipelines. The utility model has the advantages of low investment and low operating cost. Due to the three-level treatment of the grille, the mesh screen and sedimentation tanks and the additional arrangement of the anaerobic reactor and the aerobic aeration tank, the utility model can effectively eliminate SS and impurities in water, reduce the content of COD and achieve good sewage treatment effect. Moreover, the sewage can be recycled after treatment.
Description
Technical field
The utility model relates to a kind of fluting board wastewater treatment equipment.
Background technology
The production of fluting board generally is to be raw material to reclaim domestic waste and old Corrugated Box, and the principal pollutant of factory effluent are SS (suspended substance in the water quality) and a large amount of reducing substanceses, and COD (chemical oxygen demand (COD)) weighs what index of reducing substances in the water.Existing method of wastewater treatment is a kind of to be the materialization processing mode, and this kind wastewater treatment equipment is simple in structure, and SS and COD are still higher in the processed waste water, promptly can not qualified discharge, and again can not complete-reclaiming.Another kind of processing mode is that materialization adds the method that biochemical plus depth is handled, this kind waste water treatment process complexity, and processed waste water SS and COD can qualified discharges, but the cost of investment height, the operational management difficulty is big.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the fluting board wastewater treatment equipment that provide a kind of less investment, running cost is low and it is effective to dispose of sewage, processing back sewage can reach the reuse requirement.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of fluting board wastewater treatment equipment, comprise that the water collecting basin, the screen cloth that connect in turn drag for stock tank, preliminary sedimentation tank, hydrolysis acidification pool and second pond, the water collecting basin top is provided with grid, it is characterized in that: anaerobic reactor and aerobic aeration tank are set between hydrolysis acidification pool and the second pond, each the device between by pump and pipeline connection.
Screen cloth connects the recovery stock tank after dragging for stock tank, and waste water is behind screen cloth, and solid matters such as fiber fines in the water and big particle and impurity are retained in the screen cloth wire side and enter the recovery stock tank, and by the pumped back slip house, processed waste water enters in the preliminary sedimentation tank.Wherein, screen cloth drags for the preferred tiltedly net of screen cloth in the stock tank, and is simple and practical, can solve problems such as power consumption that decker and many disks thickner exist is big.
Principle of work and process:
Waste water is the 10-20mm grid by the lattice distance at first, and the bulk in the interception waste water suspends or the buoyant dirt, prevents block pumps or pipeline.Waste water through grid enters water collecting basin, carries out the storage homogeneous of waste water after mixing.Waste water rises to screen cloth by pump and drags for the stock tank place, and fiber fines in the water and big particle and impurity are held back by oblique net, and carries to processing back, workshop fully recovering by pump.Clean relatively waste water by oblique net enters preliminary sedimentation tank, through after about 4-5 hour the residence time, part SS and silt particle etc. be deposited at the bottom of the pond be collected into the bottom through Scraping device and by tubes rows to sludge sump.Primary water by around weir plate evenly overflow and enter hydrolysis acidification pool, in hydrolysis acidification pool, add nutritive salt etc., enter anaerobic reactor by pumping then, COD in the waste water is transformed biogas and anaerobic grain sludge, the waste water gravity flow enters the aerobic aeration pond, further resultant product such as COD chemical recycling of carbon dioxide, water, aerobic sludge in the waste water are removed by aerobic bacteria, be able to effective removal through most COD after anaerobism and the aerobic treatment like this.Afterwards, waste water enters second pond by the aerobic aeration pond to carry out final sedimentation and handles, mud be collected into the bottom equally and by tubes rows to sludge sump, SS and COD in the waste water reduce once more, reach reuse standard.Handle the clean waste water in back and enter reuse pool, to the workshop, as the slurry dilution water, high-low pressure rinse water, mechanical seal water etc. recycles by pump delivery.Being promoted to dehydration after mud in the sludge sump mixes presses the mud machine to carry out concentration.
The beneficial effect that the utility model had is: a kind of fluting board wastewater treatment equipment is provided, complete assembly less investment, running cost are low, by adopting grid, screen cloth, sedimentary tertiary treatment mode, and interpolation anaerobic reactor and aerobic aeration tank, can effectively remove SS and foreign matter content in the water, reduce COD content, good sewage processing effect, sewage can reach the reuse requirement after treatment.
