Description
Technical field
The invention discloses the processing method of a kind of dyeing waste water, particularly relate to the processing method of a kind of copper phthalocyaine dye stamp washing waste water.
Background technology
Copper phthalocyaine dye is bright in colour, strong coloring force, has the fastness of excellence, is irreplaceable blue kind.While its use brings distinct economic, the waste water produced after washing due to copper phthalocyaine dye textile printing, acid strong, colourity is big, and biodegradability is low also causes the most serious pollution to environment.At present, the processing method that copper phthalocyaine dye stamp washing waste water is main is materialization Coagulation Method, two-stage activated sludge process, materialization+biochemistry, Fe-C micro electrolysis etc..Biochemical process floor space is big, and narrow application range, effect is the most undesirable；Although electrolysis effect is preferable, but energy resource consumption is big, Difficulty.Patent CN103663781A discloses " a kind of Treatment method for copper phthalocyanine BGS production wastewater ", the method uses calcium hydroxide to be neutralized, add appropriate sodium sulfide copper removal, filtrate is concentrated by concentration systems, obtain distilled water and concentrated solution, distilled water directly reclaims, and through oven drying, concentrated solution is obtained Blocky chlorinated calcium.But, materialization complex steps, it is difficult to operation.China's plumbing paper discloses " light electrolysis/stripping/precipitation/AO PROCESS FOR TREATMENT Copper Phthalocyanine Wastewater ", and copper phthalocyanine produces the mother solution of waste water through reclaiming CaCl2After condensed fluid and flushing waste water mixing, composite waste is processed by the technique using light electrolysis, stripping, precipitation, A/O method to combine, effluent quality is made to reach the primary standard of integrated wastewater discharge standard (GB 8978-1996), this technique floor space is big, energy consumption is high, and cost is high.Patent CN 103523960A discloses " C.I. Pigment Blue 15 mother liquid disposal system ", C.I. Pigment Blue 15 mother liquid disposal system, use connected collecting-tank successively, reaction tank, filter press, pH regulator pond, ammonia-nitrogen stripping tower, C.I. Pigment Blue 15 mother solution is processed by two Buffer Pools, it is possible to reclaim copper and ammonium is that good condition is created in follow-up biochemical treatment simultaneously.But it is big to there is investment in fixed assets, and copper and ammonium reuse are relatively costly, the shortcoming that reclamation rate is on the low side.
Summary of the invention
The problem existed for above-mentioned prior art, the invention provides the processing method of a kind of copper phthalocyaine dye stamp washing waste water, the printing and dyeing alkaline waste water that basicity is big, float is high, biodegradability is low is used to mix generation precipitation according to a certain percentage with copper phthalocyaine dye stamp washing waste water, there is good removal effect after filtering, can be that good condition is created in follow-up biochemical treatment, biochemical treatment system can be directly entered and carry out a biological disposal upon；Also printing and dyeing alkaline waste water can be made effectively to be administered and not produce extra-pay simultaneously.Copper phthalocyaine dye stamp washing waste water and printing and dyeing alkaline waste water are all very difficult to the waste water processed, the most any waste water individual processing not only treatment effect is undesirable, and expense can be the highest, both can reduce the content of both Pollutants in Wastewaters through certain proportion mixing simultaneously, reduce COD (COD) and the colourity of waste water, improve the biodegradability of waste water.Iron salt or aluminum salt flocculant can also be coordinated during the mixing of both waste water to use, improve COD and the clearance of colourity.Printing and dyeing alkaline waste water is one or more in alkaline scouring waste water, mercerising washing waste water or batik alkali-wash waste water.The method of wastewater treatment of this treatment of wastes with processes of wastes against one another is simple to operation, is nearly free from expense, it is easy to promote.
The present invention uses printing and dyeing alkaline waste water and copper phthalocyaine dye stamp washing waste water to mix according to certain ratio, and to make pH be 7-10, the ammonia that recycling blow-off method will be present in copper phthalocyaine dye stamp washing waste water is got rid of, precipitation 5-10min, precipitate is filtered out, reduce COD (COD) and the colourity of waste water, improve the biodegradability of waste water after mixing simultaneously.
The present invention is realized by the following technical programs, the processing method of a kind of copper phthalocyaine dye stamp washing waste water, comprises the following steps:
(1) printing and dyeing alkalescence washing waste water is mixed according to the ratio of 1:4-8 with copper phthalocyaine dye stamp washing waste water, in the range of making pH be 7-10；
(2) ammonia using blow-off method to will be present in copper phthalocyaine dye stamp washing waste water is got rid of, and precipitates 5-10min；
(3) precipitate is filtered out, reduce COD (COD) and the colourity of waste water, improve the biodegradability of waste water；
(4) supernatant effluent after precipitation can be directly entered biological treatment system.
Described printing and dyeing alkaline waste water is one or more in alkaline scouring waste water, mercerising washing waste water or batik alkali-wash waste water.
Beneficial effect of the present invention
1. the present invention also makes printing and dyeing alkaline waste water difficult to deal be effectively addressed while processing copper phthalocyaine dye stamp washing waste water, reaches the effect of the treatment of wastes with processes of wastes against one another, and does not produce extra charge.
2. to process technique simple to operation for the present invention, it is simple to promotes；Cost is extremely low.
3. the present invention is after the COD (COD) reducing copper phthalocyaine dye stamp washing waste water and colourity, improves the biodegradability of waste water, can be directly entered biological treatment system.
