Chemical synthetic fibre factory waste water containing phenol removal process
The definition of synthetic fiber synthetic fiber (
Is one of the types of chemical fiber, are made from synthetic polymer made by raw materials chemical fiber.
It with small molecule organic compounds as raw material, through the addition polymerization and polycondensation reaction in the synthesis of linear organic polymer compounds, such as polyacrylonitrile, polyester, polyamide, etc.
Can be seen from the classification of fiber it belongs to a category of chemical fiber.
the preparation method of synthetic fiber the chemical composition of synthetic fiber and natural fiber, a completely different from some itself does not contain cellulose and protein substances such as oil, coal, natural gas, limestone, or agricultural and sideline products, processing of organic material, then made fiber chemical synthesis and the method of mechanical processing.
Such as polyester, polyamide, acrylic, polypropylene and chlorofibre.
the purpose of the synthetic fiber as a result of synthetic fibre is a synthetic, have appropriate molecular weight and soluble (
Linear polymers, sex by spinning forming and post-processing of chemical fiber.
Usually such as into polymer called fiber forming polymer fiber performance.
Compared with natural fiber and synthetic fiber, synthetic fiber raw material is made, synthetic method, the production is not restricted by natural conditions.
Synthetic fiber in addition to the general superior performance of chemical fiber, such as high strength, light weight, easy to wash quick drying, good elasticity, does not fear the mold cavity thereof, different varieties of synthetic fiber has some unique properties.
chemical pollutants in the process of synthetic fiber synthetic fiber factory produces chlorine, ammonia, sulfur dioxide, carbon dioxide, hydrogen sulphide, aniline, nitrobenzene and benzene, nitric acid if long-term living in such an environment, is bound to respiratory tract infection, unavoidably have lupus, or skin ulcers, noise pollution will affect the surrounding residential areas, chemical synthetic fibre factory will cause the water pollution, disorderly discharge can cause water pollution.
element analysis in the process of synthetic fiber sewage chemical synthetic fibre factory production process of all kinds of waste water, such as PET waste water, PTA wastewater, cotton pulp black liquor, viscose wastewater, etc.
The wastewater composition complex, often contain strong acid, strong alkali, cellulose and hemicellulose, alcohols, pectin, etc. , as well as a variety of toxic substances, such as PET main pollutants in the waste water for b two vinegar, ethylene glycol, ethylene glycol acetate, terephthalic acid and its intermediate and oligomer;
In the PTA wastewater mainly contain phthalate, p-xylene, benzoic acid, acetic acid lipid, acetic acid and other pollutants;
Wastewater containing poly vinegar, PTA, acetaldehyde, EG, diethylene glycol, triethylene glycol and spinning oil pollutants.
complexation extraction chemical synthetic fibre factory waste water containing phenol removal process the core of the technology for the new type of chelating extraction agent and high efficient centrifugal extraction machine, complexation extraction processing technology of wastewater containing phenol chemical fiber factory is reversible complex should be combined with extraction separation process.
complexation extraction processing technology of wastewater containing phenol chemical synthetic fibre factory, simple operation, less equipment investment, low consumption, recycling phenol can reuse, extraction raffinate phenol is lower than the emission standards, to create a direct social and economic benefits, is better than that of other domestic extraction technology of removing phenol.
the characteristics of phenol wastewater treatment equipment . cwl type centrifugal extraction machine mixing and separation in one multi-function extraction equipment.
Is mainly used in environmental protection, fine chemical, petrochemical, pharmaceutical, wet metallurgy industries of liquid liquid extraction, neutralize or water purification process.
. cwl type centrifugal extraction machine compared with other extraction equipment are: the equipment is small in size, high extraction efficiency, extraction flow than the big, wide applicable scope of materials handling system, etc, to improve product quality, reduce consumption, simplify the process, convenient operation, the expansion of production capacity, reduce the area has a better effect.
