Abstract
The present invention provides a kind of clothes dyeing and printing sewage to process technique, and it includes the modes such as filtration, discoloration, flocculation reaction, separation of solid and liquid and processes.Wherein, decolourizing agent A and B is added during discoloration, decolourizing agent A by potassium permanganate, that 1:1 pressed by bodied ferric sulfate is formulated, decolourizing agent B by melamine, glyoxal, that ammonium chloride presses 10:2:3 is formulated, the processing method of this programme is simple and practical, convenient management, and operational stability is strong, maintenance workload is little, adapts to sewage quality and feature that the water yield changes greatly simultaneously.Discharge water quality after process reaches " textile dyeing and finishing emission of industrial pollutants standard ".
Description
Technical field
The present invention relates to technical field of sewage, refer in particular to a kind of clothes dyeing and printing sewage and process technique.
Background technology
Needs due to production technology, printing and dyeing workshop to discharge a certain amount of waste water, these waste water contain substantial amounts of organic matter, colourity, sulfide, dyestuff and part of auxiliary, alkali etc., these waste water directly discharge certainly will cause severe contamination to surrounding environment without any process, the selection of sewage treatment process is the key that dyeing and printing sewage processes engineering construction, whether proper process process choice, not only affect treatment effect, but also the capital expenditure of impact whole process engineering is how many, process the degree of reliability of process operation, operating cost height and the complexity of management operation.
Content of the invention
It is an object of the invention to provide a kind of high treating effect, fireballing clothes dyeing and printing sewage processes technique.
For achieving the above object, technical scheme provided by the present invention is: a kind of clothes dyeing and printing sewage processes technique, and it includes following steps:
1) filtering: sewage enters in grille well, the grid filtration in grille well removes the bulk solid foreign material in sewage and fraction solids suspension；
2) discoloration: the sewage of above-mentioned removal bulk solid foreign material and fraction solids suspension enters in regulating reservoir A, decolourizing agent A is added in regulating reservoir A, decolourizing agent A by potassium permanganate, that 1:1 pressed by bodied ferric sulfate is formulated, adds 25 ~ 100mg decolourizing agent A in every liter of waste water；Suction regulating reservoir B after stirring, adds decolourizing agent B in regulating reservoir B, decolourizing agent B by melamine, glyoxal, that ammonium chloride press 10:2:3 is formulated, in every liter of waste water, addition 55 ~ 100mg decolourizing agent B, stirs；
3) flocculation reaction: the sewage after being adjusted enters in flocculation tank, adds flocculant, and flocculant is added water by PAFC, polyacrylamide and makes, and its ratio is 10:2:88, and the addition of flocculant is 65 ~ 110mg/L waste water；Stir, make the colloidal substance in sewage and solid suspension and flocculant be sufficiently mixed, form solid floccule body；
4) separation of solid and liquid: the above-mentioned sewage containing solid floccule body enters sedimentation basin and carries out separation of solid and liquid, adds alum and lime by sedimentation basin capacity, and alum addition is 1950mg/L, and lime adding amount is 500mg/L；Make the solid floccule body in sewage settle formation solid sludges in sedimentation basin, be deposited at the bottom of pond；Solid sludges after sedimentation is processed by sludge treating system.
The sewage water treatment method of this programme is simple and practical, convenient management, and operational stability is strong, and maintenance workload is little, adapts to sewage quality and feature that the water yield changes greatly simultaneously.Discharge water quality after process reaches " textile dyeing and finishing emission of industrial pollutants standard ".
Detailed description of the invention
The invention will be further described below, and presently preferred embodiments of the present invention is: clothes dyeing and printing sewage described in the present embodiment processes technique and includes following steps:
1) filtering: sewage enters in grille well, the grid filtration in grille well removes the bulk solid foreign material in sewage and fraction solids suspension；
2) discoloration: the sewage of above-mentioned removal bulk solid foreign material and fraction solids suspension enters in regulating reservoir A, adds decolourizing agent A in regulating reservoir A, decolourizing agent A by potassium permanganate, that 1:1 press by bodied ferric sulfate is formulated, addition 25mg decolourizing agent A in every liter of waste water；Suction regulating reservoir B after stirring, adds decolourizing agent B in regulating reservoir B, decolourizing agent B by melamine, glyoxal, that ammonium chloride press 10:2:3 is formulated, in every liter of waste water, addition 55mg decolourizing agent B, stirs；
3) flocculation reaction: the sewage after being adjusted enters in flocculation tank, adds flocculant, and flocculant is added water by PAFC, polyacrylamide and makes, and its ratio is 10:2:88, and the addition of flocculant is 650mg/L waste water；Stir, make the colloidal substance in sewage and solid suspension and flocculant be sufficiently mixed, form solid floccule body；
4) separation of solid and liquid: the above-mentioned sewage containing solid floccule body enters sedimentation basin and carries out separation of solid and liquid, adds alum and lime by sedimentation basin capacity, and alum addition is 1950mg/L, and lime adding amount is 500mg/L；Make the solid floccule body in sewage settle formation solid sludges in sedimentation basin, be deposited at the bottom of pond；Solid sludges after sedimentation is processed by sludge treating system.
The sewage water treatment method of this programme is simple and practical, convenient management, and operational stability is strong, and maintenance workload is little, adapts to sewage quality and feature that the water yield changes greatly simultaneously.Discharge water quality after process reaches " textile dyeing and finishing emission of industrial pollutants standard ".
