Description
Technical field
The utility model relates to dyeing apparatus field, particularly relates to a kind of dyeing waste water heat recovery system.
Background technology
Dyeing waste water is processing cotton, fiber crops, chemical fibre and blending product thereof is the waste water that main printing and dyeing mill discharges.The dyeing waste water water yield is comparatively large, and every dyeing and printing process 1 ton of textiles water consumption 100 ~ 200 tons, wherein 80 ~ 90% become waste water.Textile printing and dyeing wastewater has the features such as the water yield is large, organic pollution content is high, alkalescence is large, change of water quality is large, belong to one of unmanageable industrial wastewater, containing dyestuff, slurry, auxiliary agent, finish, soda acid, fiber impurity, sand class material, inorganic salts etc. in waste water.
The processing method that main method for treatment of dyeing wastewater has physico-chemical process, biochemical process, chemical method and several technique to combine, and the preliminary treatment in wastewater treatment is mainly in order to improve waste water quality, remove suspended matter and can the impurity of direct sedimentation, regulate waste water quality and the water yield, reduction wastewater temperature etc., improve the whole structure of wastewater treatment, guarantee the stability of whole treatment system, therefore preliminary treatment has extremely important status in treatment of dyeing wastewater.
Dyeing is industrial wastewater discharge rich and influential family, and according to incompletely statistics, national dyeing waste water discharge capacity every day is 3 × 106 ~ 4 × 106m3.Dyeing waste water has the features such as the water yield is large, organic pollution content is high, colourity is dark, alkalescence is large, change of water quality is large, belongs to unmanageable industrial wastewater.
The kind of dyeing waste water generally has following several:
1. desized wastewater, the water yield is less, and pollutant levels are high, and main containing slurry and analyte, Soft flocks, acid, starch alkali and enzyme pollutant, turbidity is large.Waste water is in alkalescence, and pH value is about 12.All high with BOD, COD during starch size, good biodegradability; Very high with COD during synthetic slurry, BOD is less than 5mg/L, and water biodegradability is poor;
2. boiled-off waste water, the water yield is large, and pollutant levels are high, mainly containing cellulose, tartaric acid, wax, grease, alkali, surfactant, nitrogen-containing compound etc.Waste water alkalescence is very strong, and water temperature is high, and in brown, COD and BOD is very high, reaches often liter of thousands of milligram.The pollution of chemical fibre boiled-off waste water is lighter;
3. bleaching effluent, the water yield is large, pollutes comparatively light, main containing remaining bleaching agent, a small amount of acetic acid, oxalic acid, sodium thiosulfate etc.;
4. mercerizing waste water, alkalinity is high, and NaOH content is at 3%-5%, and most printing and dyeing mill reclaims NaOH by evaporation and concentration, so mercerizing waste water generally little discharge, repeatedly use final waste water of discharging still in strong basicity through technique, BOD, COD, SS are all higher;
5. dyeing waste-water, water quality is changeable, sometimes containing the noxious material (akali sulphide, tartar emetic, aniline, copper sulphate, phenol etc.) during the various dyestuff of use, and alkalescence, PH reaches more than 10 (when adopting sulfuration, reducing dye) sometimes, containing organic dyestuff, surfactant etc.Colourity is very high, and SS is few, and COD comparatively BOD is high, and biodegradability is poor;
6. printing waste water, containing slurry, BOD, COD are high;
7. arranging process waste water, mainly containing Soft flocks, resin, formaldehyde, finish and slurry, the water yield is few;
8. alkali decrement waste water: be that terylene artificial silk Alkali reduction operation produces, main containing terylene hydrolysate terephthalic acid (TPA), ethylene glycol etc., wherein terephthaldehyde's acid content is up to 75%.Alkali decrement waste water is pH value high (general >12) not only, and organic concentration is high, the CODCr in wastewater of Alkali reduction operation discharge can up to 90,000 mg/L, macromolecule organic and some dyes are difficult to be biodegradable, and this kind of waste water belongs to high concentration hard-degraded organic waste water.
Existing printing and dyeing wastewater treatment system generally directly processes boiled-off waste water, then get rid of, on the one hand, the waste heat of boiled-off waste water is very high, generally has 50 degree to 60 degree, do not make full use of its waste heat just directly to get rid of, extremely waste, on the other hand, because dyeing waste water needs to carry out biochemical treatment, too high water temperature easily will make biochemical bacterial death, affect wastewater treatment process.
