Abstract
The invention provides a method for processing municipal wastewater, which is characterized in that the municipal wastewater is treated by a composition composed of the following components: active carbon, zeolite mineral, montmorillonite and polyacrylamide. The method for processing municipal wastewater is capable of rapidly absorbing the impurities such as organic substances and inorganic substances in municipal wastewater, and can realize standard discharge of the sewage, and the method has the advantages of low cost, non toxicity and no corrosion.
Description
Technical field
The invention belongs to technical field of waste water processing, be specifically related to a kind of method of processing city domestic sewage.
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 that is separated, reclaimed undissolved suspended state pollutent in 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 is mainly the method with medicament and the pollutent thrown in neutralize, the chemical reaction such as coagulation, redox carries out wastewater treatment.But the method process range is narrow, the wastewater treatment ability many to organism.
Biological treatment is to make organic pollutant in sewage be converted into the method for stable harmless object by the metabolism of microorganism.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 a kind of method of high-level efficiency, low-cost processes city domestic sewage.
Particularly, the present invention is a kind of method of processing city domestic sewage, it is characterized in that, uses the compositions-treated city domestic sewage of following component: gac, zeolite group mineral, montmorillonite, polyacrylamide.
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, more preferably: gac 20-25 part, zeolite group mineral 18-20 part, montmorillonite 15-18 part, polyacrylamide 5-8 part, be particularly preferably: 22 parts of gacs, 19 parts of zeolite group minerals, 16 parts of montmorillonites, 6 parts of polyacrylamides.
Gac claims again active black, is black powder shape or the granular decolorizing carbon obtaining through charing, activation and aftertreatment with raw materials such as coal, timber and shells.Gac, structurally due to microcrystalline carbon irregular alignment, has pore between cross connection, when activation, can produce carbon tissue defects, and therefore it is a kind of porous carbon, and tap density is low, pore texture prosperity, the large (1500m of specific surface area
2more than/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 Gas Phase Adsorption, as power plant, petrochemical industry, refinery, food-drink, sugaring alcoholic, medicine, electronics, breed fish, the purification of water quality processing of the industry such as sea-freight, free chlorine, phenol, sulphur and other organic pollutant in energy active adsorption water, the particularly precursor of mutagen (THM), the object that reaches purification and impurity removal and remove peculiar smell.
Zeolite group mineral is the manosil AS mineral of a kind of moisture basic metal or alkaline-earth metal, there is the three-dimensional framework being formed by silicon (aluminium) oxygen tetrahedron, in skeleton, there are hole of all sizes and passage, these holes and passage play the effect of strainer and molecular sieve, can optionally adsorb or filtered wastewater in organism or inorganics, be therefore widely used in the aspects such as sewage purification.
Montmorillonite has another name called montmorillonite, is the layer mineral being made up of the superfine hydrous alumino silicates of particle, has very strong adsorptive power and cation exchange property, is widely used in chemical reaction to produce adsorption and cleaning action.In the time that montmorillonite uses together with zeolite group mineral, 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 liquid, forms larger flco and produce thus huge surface adsorption effect between particle.Process and use polyacrylamide to be generally divided into two processes for city domestic sewage: 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 (writes a Chinese character in simplified form APAM, molecular weight 800-2000 ten thousand), cationic polyacrylamide (writes a Chinese character in simplified form CPAM, molecular weight 800-1200 ten thousand, ion degree 10%-80%).
The present invention can be adsorbed the impurity such as organism and inorganics in city domestic sewage efficiently, rapidly, realizes the qualified discharge of sewage, and the method cost is low, nontoxic, non-corrosiveness.
