Abstract

The invention provides a method for treating electroplating wastewater. The method for treating the electroplating wastewater is characterized in that the electroplating wastewater is treated by a composite comprising the following components: active carbon, zeolite ore, montmorillonite, polyacrylamide and sodium sulfide. According to the method for treating the electroplating wastewater, disclosed by the invention, impurities, such as heavy metal ions, organic matters and other inorganic matters, in the electroplating wastewater can be highly efficiently and quickly adsorbed and removed, and the standard drainage of waste water is realized; and the method for treating the electroplating wastewater, disclosed by the invention, has the advantages of low cost, no toxicity and no corrosiveness.

Description

A kind of method of processing electroplating wastewater
Technical field
The invention belongs to technical field of waste water processing, be specifically related to a kind of method of processing electroplating wastewater.
Background technology
Existing method of wastewater treatment has physical treatment process, method of chemical treatment, biological treatment.
Physical treatment process is the most original water treatment method, is the method for separating, reclaim undissolved suspended state pollutent in the sewage by modes such as gravity stratification, centrifugal or filtrations.The method is simple, but can only do some simple wastewater treatments, and processing is very incomplete, is difficult to qualified discharge.
Method of chemical treatment mainly is the method with medicament and the pollutent thrown in neutralize, the chemical reactions such as coagulation, redox carry out wastewater treatment.But the method process range is narrow, the wastewater treatment ability many to organism.
Biological treatment is that the metabolism by microorganism makes organic pollutant in the sewage be converted into the method for stable harmless object.But the method treatment scheme is long, facility investment is large, operating cost is high, heavy metal ion is difficult to remove.
Summary of the invention
The present invention aims to provide the method for a kind of high-level efficiency, low-cost processes electroplating wastewater.
Particularly, the present invention is a kind of method of processing electroplating wastewater, it is characterized in that, uses the compositions-treated electroplating wastewater of following component: gac, zeolite group mineral, montmorillonite, polyacrylamide, sodium sulphite.
Wherein, each constituent mass proportion optimization of described composition is: gac 15-25 part, zeolite group mineral 15-20 part, montmorillonite 15-25 part, polyacrylamide 5-10 part, sodium sulphite 2-8 part, more preferably: gac 20-25 part, zeolite group mineral 18-20 part, montmorillonite 15-18 part, polyacrylamide 5-8 part, sodium sulphite 3-5 part are particularly preferably: 22 parts of gacs, 19 parts of zeolite group minerals, 16 parts of montmorillonites, 6 parts of polyacrylamides, 4 parts in sodium sulphite.
Gac claims again active black, is black powder shape or the granular decolorizing carbon that obtains through charing, activation and aftertreatment with raw materials such as coal, timber and shells.Gac has pore structurally because the microcrystalline carbon irregular alignment between cross connection, can produce the carbon tissue defects during activation, so it is a kind of porous carbon, and tap density is low, and pore texture is flourishing, the large (1500m of specific surface area 2More than/the g), high adsorption capacity, be widely used in the deep purifying of tap water, process water and waste water, industrial purification of water quality and the Gas Phase Adsorption, such as power plant, petrochemical industry, refinery, food-drink, sugaring alcoholic, medicine, electronics, breed fish, the purification of water quality of the industry such as sea-freight processes, free chlorine, phenol, sulphur and other organic pollutant in the energy active adsorption water, particularly the precursor of mutagen (THM) reaches the purpose that purification and impurity removal removes peculiar smell.
Zeolite group mineral is a kind of moisture basic metal or the manosil AS mineral of alkaline-earth metal, has the three-dimensional framework that is consisted of by silicon (aluminium) oxygen tetrahedron, hole of all sizes and passage are arranged in the skeleton, these holes and passage play the effect of strainer and molecular sieve, can optionally adsorb or filtered wastewater in organism or inorganics, therefore be widely used in the aspects such as sewage purification.
Montmorillonite has another name called montmorillonite, is the layer mineral that is made of the superfine hydrous alumino silicates of particle, has very strong adsorptive power and cation exchange property, is extensively applied in the chemical reaction to produce adsorption and cleaning action.When montmorillonite and zeolite group mineral use together, can make montmorillonite and zeolite group mineral play complementary collaborative effect by micro-porous adsorption and ion-exchange.
Polyacrylamide is that molecular weight has good flocculence by millions of to several macromolecular water-soluble organic polymers of ten million, can reduce the frictional resistance between the liquid, forms larger flco and produce thus huge surface adsorption effect between particle.Use polyacrylamide generally to be divided into two processes for electroplating wastewater processing: the one, the charge neutralization of polymer electrolyte and particle surface; The 2nd, the long-chain of polymer electrolyte and tiny suspended particles are built bridge and are formed thicker floc sedimentation, and along with the increase of floc sedimentation, settling velocity increases gradually.Domestic representational high polymer polyacrylamide has at present: non-ionic polyacrylamide (is write a Chinese character in simplified form NPAM, molecular weight 800-1500 ten thousand), anion-polyacrylamide (is write a Chinese character in simplified form APAM, molecular weight 800-2000 ten thousand), cationic polyacrylamide (is write a Chinese character in simplified form CPAM, molecular weight 800-1200 ten thousand, ion degree 10%-80%).
Sodium sulphite can with waste water in cupric ion, lead ion, zine ion, mercury ion and nickel ion etc. react, generate precipitation, realize effective removal of heavy metal out of electroplating wastewater ion.
The present invention can be efficiently, adsorb rapidly, remove the impurity such as heavy metal ion, organism and other inorganics in the electroplating wastewater, realize the qualified discharge of waste water, and the method cost is low, nontoxic, non-corrosiveness.
