Description
Technical field
The utility model belongs to the environmental technology field in floride-free the no ammonia four unification aluminium shape surface treatment process, and more specifically relating to does not a kind ofly have ammonia four in free-floride and unify the online water cycle refining plant that uses in the aluminium shape surface treatment process.
Background technology
Surface treatment be utilize physics, chemistry, perhaps additive method, the one deck that forms in the metallic surface has certain thickness, is different from body material and the tectum of certain reinforcement, protection or specific function is arranged.Process of surface treatment comprises matrix pre-treatment, coating prepn, three parts of coating aftertreatment.The master operation that typical aluminium shape surface is handled comprises chemical rightenning, oil removing, alkali erosion, pickling, neutralization, oxidation, sealing of hole, painted, passivation etc.In each operation, all use various soda acids to make surperficial treatment solution; Because the viscosity of various treatment solutions and physicochemical property are different; Aluminium shape surface can be handled the thick liquid membrane of taking different amounts the tank liquor out of from these viscosity; Need a large amount of clear water to clean and remove these liquid films, handle aluminium per ton and consume 25～30 cubic metres of water approximately, the water after cleaning becomes the main waste water that aluminium shape surface is handled.The aluminium shape surface treatment process is traditional is divided into alkali etching technique and acid etching technology, no matter which kind of mode, each road technology that aluminium shape surface is handled includes handles and clean, and produces a large amount of Cleaning Wastewater and dense waste liquid.Present aluminium section bar manufacturing enterprise more than 90% adopts fluorine-containing technology that aluminium shape surface is handled, and produces waste water containing fluorine, because the chemical agent that each operation is added in chemical liquid groove is different, and the composition more complicated of pollutent.The major pollution thing comprises fluorion, ammonia nitrogen, COD, sexavalent chrome, organism, sulfate radical, phosphate radical etc. in the aluminium factory effluent; Know according to preceding surface analysis: even discharge by the secondary discharge standard of requirement at present; Still can cause certain pollution to water body, failing qualified discharge then endangers bigger.China has become the big producing country of world aluminum section bar through the great development of two more than ten years, and aluminium section bar output was sure to occupy the No. 1 in the world in continuous 5 years.Present national aluminium shape surface is handled annual 9200000 tons, and Guangdong Province's yearly capacity is above more than 200 ten thousand tons.Aluminium per ton consumes 15～40 kilograms of aluminium through surface treatment, produces 150～400 kilograms of waste slag of aluminum simultaneously.Calculate with this, national annual waste residue amount 138～3,680,000 tons be equivalent to several large-scale aluminium ores, and the bauxite resource of China is poor, is again simultaneously that aluminium consumes big country.Therefore should only not be conceived to how to handle making its emission standard that reaches regulation in China's Study on wastewater that processing is discharged to aluminium shape surface, more should pay attention to cycling utilization of wastewater research and waste reside comprehensive utilization.The waste residue combination treatment of at present many aluminium section bar manufacturing enterprises is stacked and is unfavorable for very much waste reside comprehensive utilization.
Tradition acid etching and alkali etching technique, water quality is good inadequately after treatment for the waste water of each operation discharging, causes the water of ability reuse less, and most of directly outwards discharging not only causes water pollution but also waste great amount of water resources.The viewpoint that floride-free no ammonia four unifications in 2010 are handled is suggested, and its advantage is: the first pair of waste water carries out filter operation (through the scum silica frost filter bag is set) thereby the cyclically utilizing water displacement of trying one's best is few; Second adopts and to add the flocculation agent mode waste residue is dewatered, but adds the performance that flocculation agent itself can destroy tank liquor, and making it not only can not reuse be to make that waste residue can not the efficient resource utilization on the contrary, and to the extra difficulty of waste residue dehydration generation.This new aluminium shape surface treatment process still has discharge of wastewater, also wastes resource.
In sum, China is as aluminium section bar big producing country, and its waste water circulation and waste reside comprehensive utilization all have very significant meaning for healthy Sustainable development of aluminium section bar production and environment protection.Can the usefulness that be recycled up to standard after the waste water that each operation produced of therefore hoping the aluminium shape surface treatment process in a hurry purifies, and waste residue fully utilized, also there is not technology can accomplish this step at present.Handle the online water cycle refining plant of floride-free no ammonia four unification technologies at following novel proposition aluminium shape surface of this background and realize wastewater zero discharge; Each operation that aluminium shape surface is handled realizes that online water cycle purifies; And dewater and become useful waste residue purifying trapped substance; Really accomplish waste water circulation and waste reside comprehensive utilization purpose that aluminium shape surface is handled, kill two birds with one stone.
The utility model content
Still there are discharge of wastewater and the unserviceable problem of waste residue in order to solve the floride-free no ammonia four unification technologies of aluminium shape surface processing; The purpose of the utility model is to provide a kind of aluminium shape surface to handle the online water cycle refining plant that uses in the floride-free no ammonia four unification technologies; A kind ofly can realize wastewater zero discharge; Each operation that aluminium shape surface is handled realizes that online water cycle purifies; And dewater and become useful waste residue purifying trapped substance, accomplish that really the waste water circulation that aluminium shape surface is handled and the aluminium shape surface of waste reside comprehensive utilization handle online water cycle purification system.For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of do not have the online water cycle refining plant that uses in the ammonia four unification aluminium shape surface treatment process in free-floride; Floride-free no ammonia four unification aluminium shape surface treatment process comprise alkaline degreasing groove 1, alkali accumulator tank 2, take out slag chute 3, clear liquid backflash 4, washing are treated hopper 5, oxidation trough 6, sour backflash 7, acid recovery moisturizing groove 8, painted groove 9, take out slag chute 10, clear liquid backflash 11, pH value control flume 12, sealing of hole groove 13, sealing of hole accumulator tank 14 and sealing of hole recovery moisturizing groove 15; It is characterized in that; Said online water cycle refining plant comprise respectively with air E1, sour backflash 7, painted groove 9 and take out the colouring slot liquid clearing machine 19 that slag chute 10 is connected, the oxidation tank liquor clearing machine 18 that is connected with air E1, sour backflash 7 and oxidation trough 6 respectively, respectively with air E1, sour backflash 7, clear liquid backflash 4 and take out slag chute 3 alkali tank liquor clearing machine 17 that is connected and the liquor of hole-sealing tank clearing machine 20 that is connected with air E1, sour backflash 7, sealing of hole groove 13 and sealing of hole accumulator tank 14 respectively, said alkali tank liquor clearing machine 17, oxidation tank liquor clearing machine 18, colouring slot liquid clearing machine 19 all are connected dashpot 16 and air E1 with liquor of hole-sealing tank clearing machine 20.Said alkali tank liquor clearing machine 17 comprises microfiltration membrane tank body E11, switch-valve (V101, V102, V103, V104, V105, V106, V107, V108, V109, V110), pump (P3, P11, P12), belt filtering unit E12, cylinder C1 and cylinder C2.
