Description
Technical field
The present invention relates to a kind of wastewater treatment equipment, be specifically related to a kind of paint of coating wastewater treatment equipment.
Background technology
The existing long history of the production of paint and application, China has just brought into use paint before several thousand, and the paint that uses at that time was to be processed into lacquer from the lacquer liquid that lacquer tree is taked.It is modern because the appearance of synthetic materials has been opened up new source to paint raw materials.After---synthetic resins, pigment and organic solvent etc.---were made paint when utilizing various synthetic materialss widely, the new variety with diversified performance had been got up with regard to the increase of making rapid progress.The coating that these just present people are familiar with.
Paint waste water is mainly derived from paint, coating material production enterprise, and is the waste water that discharges in all kinds of industry production processes of raw material with paint, and such waste water is intermittently discharged normally, and the water quality and quantity fluctuation is big.In the coating material production process, produce the waste water of discharging, wherein often contain phenols, benzene class and heavy metal hazardous and noxious substances such as (surface treatments), waste water COD cr=2000～4000mg/L BOD
5=1000～1200mg/L, pH=4-12.5 do not wait.Phenol is a kind of chemical auxocarcinogen, if the phenolic wastewater of high density is discharged into aquatic organism is suffered damage.Also contain lead and chromium in the pigment that coatings industry uses at present.Lead is pollution element the most widely at present, and its damaging effect to hemopoietic system relates generally to brain, cerebellum and spinal cord and peripheral nerve.Chromium compounds toxicity is very big, mainly gets into human body through tap water and food.Therefore coating waste-water is very serious to the harm in waters.The main raw material of paint---oil, resin and dyestuff.The component of paint has determined the composition of paint waste water.Make that the organism kinds in the waste water is many, complicated component, COD content is high, and has certain toxicity, and the characteristics of this type of waste water are: the waste water generation of (1) unit product is few, but pollutent is formed very complicacy; (2) contain multiple virose, the macromolecular organic compound that is difficult to biochemical degradation, and dense (COD＞10
20g/L); (3) solid contents is also very high in the waste water.The treatment process of paint waste water has physico-chemical process and biochemical process; The materialization partition method mainly contains air supporting, coagulating sedimentation, absorption, micro-filtration, ultrafiltration, reverse osmosis membrane separation etc.; Biochemical treatment process mainly contains aerobe processing, anaerobic biological treatment etc., the many paint waste water treatment process of the combined formation of these technologies.But exist technical process tediously long, equipment can not play one's part to the full, and processing cost is high, the qualified discharge poor stability, and treatment effect has much room for improvement.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of rational in infrastructure, flow process is simple, the new coating wastewater treatment equipment that treatment effect is good.
Technical scheme: in order to solve the problems of the technologies described above; New coating wastewater treatment equipment of the present invention; It comprises efficient air-floating water purifier, water leg, vapour and water mixed heater, up flow anaerobic sludge blanket reactor, blow-off groove, contact aerobic oxidation groove and tube settler; They are successively through pipe connection, and said contact aerobic oxidation groove comprises that one-level contact aerobic oxidation groove contacts the aerobic oxidation groove with secondary.
Said efficient air-floating water purifier, water leg, vapour and water mixed heater, up flow anaerobic sludge blanket reactor, blow-off groove, contact aerobic oxidation groove and tube settler all are to control automatically through PLC.
Be provided with the waste water import in said efficient air-floating water purifier one side, be provided with dog-house on said efficient air-floating water purifier top.
The temperature of said vapour and water mixed heater is controlled between 20-30 °.
In said up flow anaerobic sludge blanket reactor, be provided with the waste water recycle pump.
Be provided with aerating apparatus in said blow-off groove bottom.
In said contact aerobic oxidation groove, be provided with combined stuffing.
Be provided with honeycomb inclined-tube in said tube settler inside, in this honeycomb inclined-tube, be provided with filler.
Paint waste water at first gets into the efficient air-floating water purifier; Add in PAC and the extremely efficient air-floatation water purifier of PAM through volume pump; From flowing in the water leg, through steam-water injection waste water is heated to entering anaerobic mud bed reactor in back about 25 ℃ again behind grease in the removal waste water and the suspended substance.In anaerobic mud bed reactor, utilize anerobes that the organism in the waste water is decomposed into methyl etc., discharge from water with the form of gas, can remove in the waste water about 70% CODcr.Simultaneously, can also with the aromatic hydrocarbons in the waste water organic with rings such as benzene, naphthalene, anthraquinone open, improve the aerobic degradation performance of hardly degraded organic substance, for follow-up aerobic microbiological processing creating good conditions.The anaerobic mud bed reactor water outlet gets in the blow-off groove, and being provided with the stripping device at bottom land can come out the easy volatile material stripping in the waste water effectively, improves the growing environment of follow-up aerobe.Waste water gets into follow-up two-stage contact aerobic oxidation groove again, and combined stuffing is housed in the groove, is used for the aerobic microbiological apposition growth, and waste water is further removed CODcr and BOD in two-stage contact aerobic oxidation groove
5At last, waste water entering tube settler carries out getting final product qualified discharge after the solid-liquid separation.Can reduce to below the 100mg/L BOD through CODcr after this art breading
5Can reduce to below the 30mg/L.
Tube settler of the present invention bottom is provided with sludge outlet, and body refuse gets into pressure filter, realizes transporting outward disposal behind the mechanical dehydration.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: the supporting blow-off groove of anaerobic mud bed reactor is incorporated in the paint waste water treatment process, and in conjunction with air supporting, contact aerobic oxidation, tube settling technology, treatment effect is good; The complete assembly flow process is simple, and cost is reasonable.
