Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, a kind of Wastewater zero-discharge treatment system, comprises the equalizing tank 1 for being carried out adjusting by raw wastewater pH value, and the water outlet of described equalizing tank 1 is connected with the first reaction tank 2 of the first whipping appts; In first reaction tank 2, both sides are provided with protection against corrosion DC electrode, and the water outlet of described first reaction tank 2 is connected with the second reaction tank 3; Be provided with the luminescence-utraviolet device for changing carrier affinity in described second reaction tank 3, the water outlet of described second reaction tank 3 is connected with circulation concentrating unit 4; Be provided with functional film strainer in described circulation concentrating unit 4, the water outlet of described circulation concentrating unit 4 is connected with the settling tank 5 of the second whipping appts; Described settling tank 5 is connected with the filter-press arrangement 12 for settling tank base sludge being carried out press filtration; Described filter-press arrangement 12 is provided with the press filtration pipeline for the filtrate produced after press filtration being back to equalizing tank 1, and the water outlet of described settling tank 5 is connected with the tubular filter film device 6 for mud-water separation; The water outlet of described tubular filter film device 6 is connected with the first-stage reverse osmosis device 8 for purifying water, and is provided with for not filtering clean muddy water and carry out the first pipeline of reflux and filter in tubular filter film device 6 between described circulation concentrating unit 4 and tubular filter film device 6; The outlet of described first-stage reverse osmosis device 8 is connected with the second level reverse osmosis apparatus 10 purified water, and the water outlet of described second level reverse osmosis apparatus 10 is connected with water reservoir 11; The first transfer pond 7 is provided with between described tubular filter film device 6 and first-stage reverse osmosis device 8, described first transfer pond 7 is provided with for the high pressure pumping apparatus by current high-pressure delivery, the second transfer pond 9 is provided with between described first-stage reverse osmosis device 8 and second level reverse osmosis apparatus 10, the described second transfer pond 9 below standard water quality be also provided with for being flowed into by first-stage reverse osmosis device 8 carries out the second pipe being back to equalizing tank 1, described functional film strainer is curtain plates, and described luminescence-utraviolet device is cylinder.
In reaction tank 1, protection against corrosion DC electrode first DC electrode and the second DC electrode are installed in both sides, through its voltage of power supply unit adjustable.Its shape of branch of both sides protection against corrosion electrode and scale visual reaction tank body size determine, are suitably distributed in reaction tank to make Pollutants in Wastewater fully reach potential balance by voltage.
Luminescence-utraviolet device is installed in reaction tank 2, there is the wavelength that two kinds different, wavelength 185nm first luminescence-utraviolet device and wavelength 254nm second luminescence-utraviolet device are staggered and are placed in reaction tank, the ultraviolet of different wave length can change the affinity of carrier, water pollutant and carrier are combined closely, improves pollutants removal rate.
Installation functionality membrane filter (FMF) in concentration basin, this membrane filter has characteristic species filtering function, film is the hollow-fibre membrane after upgrading, pore diameter range is at 0.01 ~ 0.05 μm, belong to ultra-filtration film, film after upgrading, with electric charge, can filter predetermined substance and be isolated removal, reach the mass balance of water pollutant.
The raw wastewater that factory produces does runoff investigation and pH value adjustment after flowing into equalizing tank, add dilute sulphuric acid and water pH value is adjusted to about 3, rear inflow first reaction tank adds HE-PAC medicament simultaneously, and makes waste water and HE-PAC fully react to remove water pollutant with stirring or aeration mode.Flow into the second reaction tank afterwards, and add sodium hydroxide solution and make to produce flocs unit in water, be easy to the continuous precipitation of postorder.Flow into circulation concentrating unit afterwards, because still having the part HE-PAC medicament that not yet complete reaction is complete in concentrating unit, waste water in this device still sustainable reaction to improve processing efficiency.
Waste water after concentrated flows into settling tank again, native system settling tank still accompanies by stirring or aeration mode operation when usually running, as transition pond, muddy water mixed solution directly enters tubular filter film and carries out mud-water separation operation, product water after tubular membrane filter device flows into the first transfer pond, and as the water inlet of first-stage reverse osmosis device, tubular membrane filter after concentrated muddy water be then back in circulation concentration basin and again react.
Product water in first transfer pond sends into first-stage reverse osmosis device with high-pressure pump, and it produces water and flows into the second transfer pond, and as the water inlet of two-pass reverse osmosis, reached pure water grade because it produces water, visual workshop water water quality requirement again row utilizes.First-stage reverse osmosis filters the concentrated solution produced and is then back to equalizing tank and again processes.For guaranteeing that water quality is more pure, the product water in the second transfer pond sends into second level reverse osmosis apparatus with high-pressure pump, and its product water water quality can be used as the high-order water in processing procedure.Two-pass reverse osmosis filters the concentrated solution produced and is then back to equalizing tank and again processes.
Operationally, when in this pond, sludge concentration reaches 30% ratio, then stop stirring or aeration, and base sludge is delivered to pressure filter and carry out press filtration, filtrate is back to equalizing tank and again processes the settling tank of present treatment system, and dry mud is then cleared.
