Abstract
The invention belongs to filter cloth preparing technical fields of weaving, and provide a kind of efficient catalytic weaving filter cloth and preparation method for sewage disposal.Catalyst and inorfil are uniformly dispersed by this method first, and under high speed dispersion state, inorfil catalyst is formed by the laser sintered surface for quickly catalyst being made to be connected to inorfil；Then biomass cellulose is configured to spinning solution, addition inorfil catalyst, by spinning, the fiber inner core of formation is inorfil catalyst, and outer layer is the fiber of cellulose, and further weaving obtains the efficient catalytic weaving filter cloth for sewage disposal.Compared with conventional method; the present invention can prevent catalyst attachment insecure and fall off using laser sintering processes; obtained product adsorbs pollutant good; high strength, service life is long, and tearing-resistant performance is good; and raw material, equipment and the technique used; cost is relatively low, easily controllable, it can be achieved that industrialization, large-scale production.
Description
Technical field
The invention belongs to filter cloth preparing technical fields of weaving, and provide a kind of efficient catalytic weaving filter for sewage disposal
Cloth and preparation method.
Background technology
Industrial wastewater refers to the waste water, sewage and waste liquid generated in industrial processes, wherein containing the work outflowed with water
The pollutant generated in industry production materials, intermediate product and product and production process.With industry rapid development, waste water
Type and quantity rapidly increase, also increasingly extensively and serious to the pollution of water body, threaten the health and safety of the mankind.
Process for treating industrial waste water can be divided into four major class by its action principle：(1) physical treatment process, by physical action,
It is in suspended state polluter (including oil film and oil droplet) to detach, recycle and is undissolved in waste water, there are commonly Gravity Separations
Method, centrifugal separation, filtration method etc..(2) method of chemical treatment adds certain chemical substance into sewage, using chemical reaction come
Polluter in separation, recycling sewage, there are commonly chemical precipitation method, Coagulation Method, neutralisation, redox (including electrolysis)
Method etc..(3) physicochemical treatment method, using physics chemical action remove waste water in polluter, mainly have absorption method, from
Sub- exchange process, membrane separation process, extraction etc..(4) biological treatment is made in waste water by the metabolism of microorganism in molten
The Organic polluter of liquid, colloid and fine suspended state is converted into stable, harmless substance, can be divided at aerobe
Logos and Anaerobic biotreatment method.
Sewage contains the organic matter for being difficult to degrade and water soluble organic substance such as benzene, toluene, nitrobenzene, carbon tetrachloride, trichlorine
Methane, sulfide, dyestuff, amine, heavy metal ion etc., it is difficult to by simply precipitating or being filtered to remove.It is existing for height
The processing of concentration waste water, the main method using chemistry, biology, physics are eliminated.Chemical Treatment launches chemical agent, operation
It is costly；Biochemical method operational management is more complex, environmental adaptability is poor, floor space is larger.Physical is at low cost, holds
Manageability, but due to the limited material of high efficiency filter, wastewater purifying efficiency is not obvious.Suzhou has at a kind of waste water at present
The filtering material of reason, mainly this filtering material by porosity be 35% ~ 85% porous ceramic matrices suitable and in porous ceramic matrices suitable
The nanometer nulvalent iron particle that generates of internal in-situ constitute, the micropore size of porous ceramic matrices suitable is 2 ~ 10 microns, and in micropore
It is inside formed with velvet-like unformed silicon-iron-carbon structure, velvet-like unformed silicon-iron-carbon structure in the micropore is after absorbing water
Adsorbed film can be formed, in parts by weight, the material group of porous ceramic matrices suitable becomes：55 ~ 65 parts of diatomite, calcium-base bentonite 12
~ 15 parts, 7 ~ 12 parts of powdered carbon, 2 ~ 3 parts of starch, 4 ~ 6 parts of kaolin.
Although textile material is as effluent treatment and filtering membrane material, not only high treating effect, adaptable and at low cost
Operating personnel are required low.However, when adding and being attached to textile material progress sewage disposal by catalyst, how to make catalysis
Agent is evenly dispersed and adheres to as key.Directly not only dispersion is uneven for addition, and be difficult to fiber firm attachment, therefore decay
Loss is exceedingly fast.And disperse in the form of predecessor oxide catalyst to be attached to textile fabric, low-temperature hydrothermal reacts to be formed
