Abstract
The invention discloses a photocatalytic filter felt for processing sewage and a preparation method thereof. According to a filter screen provided by the invention, the high-efficient water-processing filter felt which has corresponding photocatalytic effects of visible light and UV is prepared by using a mesoporous material whose surface is plated with cuprous oxide and a titanium dioxide gel as the photocatalyst and using the filter felt as the carrier. The weight ratio of a composite material to a filter felt substrate is 500-50000ppm. By using the mesoporous material and the gel material as the carriers of the catalyst, the catalyst loss due to current is effectively avoided; the photocatalytic filter felt for processing sewage has advantages of high catalytic efficiency and long-lasting effects, and is especially used for the treatment of printing and dyeing organic sewage.
Description
Affiliated technical field
The present invention relates to a kind of preparation method of filter felt, relate in particular to a kind of photoresponse that has, the catalytic efficiency height, good stability is mainly used in novel filter felt that the textile industry organic sewage handles and preparation method thereof.
Background technology
Scientific research is found: Red copper oxide can respond sunlight, has good photocatalytic degradation characteristic for organic phenols, but people are for cuprous oxide catalysis degraded p-nitrophenyl class material at present, the research of methylene blue etc. only limits to nano cuprous oxide is placed organic sewage, utilizes the organic pollutant in the photocatalytic degradation organic sewage then.Efficient is not high, and makes a large amount of nanometer copper and salt thereof enter water cycle easily, causes the rich copper of water body, influences the eubiosis.The method of a kind of grade cuprous oxide machinery catalyzed degradation p-nitrophenyl class material is for example disclosed among the Chinese patent CN1657427A, disclosure of the Invention relate to the degradation method of p-nitrophenyl class material in the water body.Step comprises: (1) places reactor with p-nitrophenyl class material waste water; (2) ratio with 0.50g/L-4g/L adds grade cuprous oxide; (3) adopt additionaling power to make friction gear and reactor ground friction.Invention can realize that p-nitrophenyl class material catalyzed degradation efficient reaches more than 70%, but owing to be directly nano-powder to be added in the water body, though so realized catalyzed degradation, but polluted water body simultaneously, be difficult to realize industrialization promotion to p-nitrophenyl class material.
Titanium dioxide can effectively absorb sunlight, realizes the photochemical catalysis effect.But titanium dioxide can only effectively utilize the ultraviolet band in the sunlight, then can be not corresponding for visible light wave range.Chinese patent CN1980729 discloses a kind of resin porous-film that utilizes titanium dioxide to carry out clean water treatment, but owing to just utilized titanium dioxide to carry out photochemical catalysis, so photocatalysis efficiency is not high.Simultaneously, directly utilize nano titanium oxide also to have the big problem that runs off
Summary of the invention
The present invention is directed to the problem that exists in the background technology, a kind of photoresponse of having has been proposed, the catalytic efficiency height, good stability, be mainly used in novel filter felt of textile industry organic sewage processing and preparation method thereof, this photocatalysis sewage is handled with filter felt and preparation method thereof, and it is characterized in that: the method includes the steps of:
(1) surface is coated with the mesopore molecular sieve of nano cuprous oxide, tensio-active agent, the tetrabutyl titanate ultra-sonic dispersion forms suspension in water;
(2) filter felt is kept flat adjusting pH value 5-9 in the above solution of immersion, normal pressure or high pressure warming keep 30-60min after 60-80 ℃;
(3) take out that gadolinium is done, get final product after the drying.
The mesopore molecular sieve of surface plating nano cuprous oxide is 10 with the mass ratio of too sour positive butyl ester: 1-2;
Used surface stabilizer can be fatty alcohol-polyoxyethylene ether (AEO) in the step (1), alkylphenol polyoxyethylene (TX-10, OP-10, O ∏-10), aliphatic acid polyethenoxy (SE-10), aliphatic amine polyoxyethylene ether (levelling agent AN), alkylol amide polyoxy ethane ether, block polyoxyethylene polyoxypropylene ether nonionogenic tensides such as (PO-EO multipolymers), the mol ratio of its addition and tetrabutyl titanate is 1: 10-10: 1;
Used filter felt material is polyethylene (PE) in the step (2), polypropylene (PP), polyester (PET, PBT, PTT) fiber, one or several of glass fibre;
The weight ratio of nano composite material and filter felt is in the filter felt: 500-50000ppm;
Drying temperature is 100-150 ℃ in the step (3);
This filter felt is mainly used in the processing and the purification of weaving organic sewage.
Beneficial effect of the present invention:
1, technology of the present invention is simple, and operability is extremely strong, is fit to large-scale promotion application;
2, the nano composite material of the present invention's employing is that carrier is compound, and is safe, is difficult for running off;
3, product of the present invention can realize utilizing the efficient purifying treatment of photochemical catalysis to organic sewage, for solving environmental problem, promotes the construction of environmental protection of society to have great positive effect.
