The wastewater treating device comprises a magnetic grate 1, a reservoir 2, a magnetizer 3, a primary reaction tank 4, a secondary reaction tank 5, a bio-carbon tank 6, a filter 7 and a decolorant storage basin 8; the wastewater sequentially undergoes processes such as magnetizing treatment, gradient reaction system, bio-carbon treatment, filtering treatment and the like. Compared with the prior art, the pulping and papermaking wastewater advanced treatment unit has the advantages of scientific design, high atomization level, advanced technology, good treating effects and low treating cost, etc.
Description
Technical field
The utility model relates to a kind of paper-making effluent advanced treatment apparatus, is a kind of waste water advanced treatment unit that effectively designs at the paper-making effluent features of pollution after secondary biochemical treatment.
Background technology
At present; the technology of paper-making effluent advanced treatment mainly contains high-level oxidation technology, flocculation sediment technology, adsorption filtration technology, membrane filtration technique and biological reinforced treatment technology etc.; because aforesaid method is limited in one's ability to the removal of pollutent in the paper-making effluent after secondary biochemical treatment, the system handles expense is higher and the problems such as less stable of system; these technology all do not have the application of mass-producing, just rest on lab scale, pilot scale stage.Reasonable economically, technical reliable paper-making effluent advanced treatment technology is in blank at home.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and the paper-making effluent that a kind of system stability is good, processing costs is low, treatment effect is good advanced treatment apparatus is provided.The technical scheme that its technical problem that solves the utility model adopts is: according to the molecular structure characteristics of main color development pollutent (lignin of solubilised state and the derivative after the biochemical treatment, polyphenol etc.) in the paper-making effluent after secondary biochemical treatment, developing can be effectively and the discoloring agent of this pollutant generation chelating complex reaction generation insoluble substance.Waste water is successively handled through magnetizing apparatus processing, gradient reactive system (I and II reaction tank), biological carbon processing, four workshop sections of filter process.The slot grid are installed in the water inlet gallery of tank front; One end of magnetizing apparatus is by the pipe connection between the lift pump in flange plate and the tank, the other end joint flange sheet of magnetizing apparatus is connecting tube again, be connected with the exit end of sludge reflux pump in the second order reaction pond again, by the inlet in pipe connection first order reaction pond, sludge pump is established in bottom, first order reaction pond again; Discoloring agent storage pond connects dosing pump, and the outlet conduit of dosing pump is connected with the outlet in first order reaction pond, connects the inlet in second order reaction pond again, and sludge reflux pump is established in the bottom of two-stage coagulation settling tank; The biological carbon pond is connected by pipeline with gas blower, and micro-hole aerator and back-purge system are established in the bottom in biological carbon pond, is connected with high-pressure pump on the pipeline between biological carbon pond and the strainer.Magnetization is handled and is made waste water pass through magnetizing apparatus with higher speed, and the avtive spot of color development pollutent in the waste water is excited, and strengthens the chelating complex ability of pollutent and discoloring agent, saves the discoloring agent consumption; The gradient reactive system adopts two-stage " V-type " inclined-plate clarifying basin to form, the flco that " V-type " inclined-plate clarifying basin generates the color development pollutent in discoloring agent and the waste water forms the stable mud layer of a dynamic change in the pond, the waste water of handling passes from the mud layer of continuous replacement, discharge system after absorption, filtration, the body refuse that the two-stage reaction design generates second order reaction is back to the first order reaction system, bring into play the absorption net of chelating complexing product once more and catch effect, give full play to the effect of discoloring agent, reduce the discoloring agent consumption; The biological carbon treatment system adopts special gac as bio-carrier, and the characteristics little according to contaminant molecule in the waste water, that concentration is low, biological carbon integrate enriching pollutants and biological degradation, removes pollutants in waste water, purifying water body efficiently; Filtration treatment system adopts disc-type strainer, the suspended contaminant in the waste water that dams efficiently.
Paper-making effluent advanced treatment apparatus of the present utility model is compared with prior art, has following characteristics: one, the utility model design science rationally, guarantee the good result of waste water advanced processing; Two, the utility model is simple in structure, floor space is little, level of automation is high; Three, the utility model greatly reduces the advanced treatment expense when guaranteeing paper-making effluent advanced treatment effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a kind of structural representation of paper-making effluent advanced treatment apparatus.
Embodiment
