Abstract
The invention discloses a method of realizing zero emission by advanced treatment and reuse of dyeing waste water. Two kinds of liquids are obtained by pretreatment for filtration: one liquid is the liquid obtained by removing impurities and pollutants, then the liquid is extracted, impurities are separated, and purification and concentration are performed to obtain pure water and dye solution; the other liquid is the liquid containing impurities and pollutants, the liquid is processed by a biological processor and separated by a granule separator, the separated granular-type matter is dried into solid matters, and separated liquid is sent to a pretreatment link for reuse. The invention has simple equipment mating, easy assembly, thorough pollutant treatment and no secondary pollution, equipment is energy saving and has high efficiency and low treatment cost. The invention is suitable for industrialization and automation and realizes the liquid zero emission of dyeing waste water.
Description
Technical field
The present invention relates to a kind of method of dyeing waste water advanced treatment, specifically is the method that a kind of advanced treatment and reuse of dyeing waste water is realized zero release.
Background technology
Dyeing waste water is big with quantity discharged always, and intractability is high and become the emphasis and the difficult point of waste water treatment technical study.Particularly development of chemical ﹠ blended fabric in recent years and finishing process in printing and dye-ing development of technology make the organism of bio-refractories such as PVA slurry, New-type adjuvant enter dyeing waste water in a large number, have increased difficulty to wastewater treatment.Because advanced treatment and reuse of dyeing waste water never causes the attention that people are enough, processing backward in technique in other industry.Along with the strictness day by day of emission standard and rising steadily of water rate, people turn one's attention in dyeing waste water advanced treatment and the reuse gradually.
Summary of the invention
The invention provides a kind of advanced treatment and reuse of dyeing waste water and realize the method for zero release, little, the instant effect of its investment, energy-conservation, efficient, non-secondary pollution.
Technical scheme of the present invention is:
Advanced treatment and reuse of dyeing waste water is realized the method for zero release, it is characterized in that: be to adopt 600 purpose membrane filters to filter pre-treatment dyeing waste water, obtain two kinds of liquid: a kind of is the liquid of removing behind foreign material and the pollutent, this liquid extract, separating impurity, after removing the above impurity of molecular weight 200,000 dalton, through purifying, concentrate the material of removing below molecular weight 150 dalton, get dye solution then; Another kind is the liquid that contains foreign material, pollutent, impurity more than molecular weight 200,000 dalton, handle with biological processor, separate through the particle separation machine then, isolated granule type material is dried to solids, isolated liquid is sent into the pre-treatment link and carried out reuse.
Present device supporting simple, be easy to integrated; Pollutant Treatment is thorough, non-secondary pollution; Device energy conservation, efficient, processing cost is low; Be suitable for industrialization, automatization, realized liquid zero emission of dyeing waste water.
Embodiment
Advanced treatment and reuse of dyeing waste water is realized the method for zero release:
Get 50 tons of dyeing waste waters, adopt membrane filter that dyeing waste water is carried out pre-treatment earlier, remove the foreign material of bringing in the dyeing process, pre-treatment is the critical process of dyeing waste water advanced treatment, directly affects the recovery purity of dyestuff and the work-ing life of equipment;
Dyeing waste water is through being divided into two kinds of liquid after the pre-treatment: a kind of is the liquid of removing behind foreign material, the pollutent, the FSX-2 type dye withdrawer of this liquid being sent into 200,000 D extracts, separates, and remove greater than the impurity more than 200,000 D, receive the liquid behind the removal of contamination, QTX-2 type dye withdrawer with 150D purifies, concentrates then, get spissated dye solution, but direct reuse or spraying drying get solid-state dye and water purification, store reuse respectively; Another kind is to contain the liquid of foreign material, pollutent and reinstate SWX-B2 type biological processor with the impurity one that the FSX-2 type dye withdrawer of 200,000 D is cleared out of and make advanced treatment; Mixing liquid after biological processor is handled is separated by KLF-1 type particle separation machine, and the granule type material is dried to solids, liquid is sent into the reuse of pretreatment system circular treatment, realizes liquid zero emission.Whole process machine loss is about 2.7%.
Membrane filter is by Zhejiang Xinsheng Biological Technology Co., Ltd. development and produce, and characteristics are that into the water index is not subjected to the restriction of COD content in the waste water, do not stop up, applied widely, and be the pretreated preferred unit of trade effluent.
The dyestuff withdrawer is applicable to the recovery of polytype dyestuff by Zhejiang Xinsheng Biological Technology Co., Ltd.'s development and production.
Biological processor is developed and is produced together with how tame R﹠D institution by Hefei Jiuxin Biotechnology Co., Ltd., by selecting the processing of different engineering bacterias applicable to different trade effluents for use.
The particle separation machine is and the matching used general-purpose equipment of biological processor.By Zhejiang Xinsheng Biological Technology Co., Ltd.'s development and production.
