Background technology
In the sewage purification treatment technology, biomembrance process is a kind of common treatment process, and is good to being rich in organic high-leveled and difficult water treatment effect, is widely used in the processing of municipal effluent and high-concentration organic industrial waste water.Biomembrance process is meant that in effluent stream through locating to be provided with the method that surface growth has biomembranous immobilization carrier, its principle is that effluent stream is utilized the organic pollutant in the biological oxidation degradation of sewage when microbial film.The essence of this treatment process is to make microfaunas such as microorganism and protozoon, metazoan attached to growing on filler or other carriers, and forms membranaceous biological sludge---microbial film thereon.Sewage is with after microbial film contacts, and the organic pollutant in the sewage by the picked-up of the Institute of Micro-biology on the microbial film, is purified sewage as nutritive substance.
Filler is as biomembranous main carrier, and the quality of its performance directly has influence on the effect of sewage disposal.The filler of using in the existing sewage disposal generally can only play simple carrier about, how much absorption microorganism and microfauna depends on microorganism concn and microfauna concentration in the sewage fully on the filler.Microorganism concn is all lower in multiple high-leveled and difficult waste water, and its breeding speed of growth is slow, can the serious effect that limits sewage disposal.In addition, filler itself is generally not charged, only leans on the adsorption of the negative charge on microorganism surface, and the affinity of filling surface and microorganism is limited, and biomembranous absorption sedimentation velocity is slower, also can limit the speed and the effect of sewage purification.
Summary of the invention
The manufacture method that the purpose of this invention is to provide the ionic enzymatic suspended filler that is applied to high-leveled and difficult wastewater treatment efficiently solves that biofilm packing surface adsorption microorganism speed of the prior art is slow, the problems such as affinity difference of filling surface and microorganism.
The present invention relates to a kind of manufacture method that is applied to the ionic enzymatic suspended filler of high-leveled and difficult wastewater treatment, it is characterized in that, comprise the steps:
1) in 10000 parts of (weight part) polyolefin resin section, the wetting ability superpolymer polyethylene alcohol or the polyacrylamide that add 500-4500 part, add the polyvinylpyridine salt of 300-2000 part, the microorganism growth promotor of adding 5-500 part, mix the back high-speed stirring, obtain first fiber behind the melt-spinning;
2) with the ES fiber as second fiber, get first fiber and become fabric with second fibrage, wherein first fiber and second fibre weight ratio are 0.667: 1～4: 1;
3) get polypropylene non-woven fabric as supatex fabric, as bottom, it is alternately laminated that fabric is positioned over supatex fabric, with rope fabric and supatex fabric is fixed together, and obtains the duplexer of fabric and supatex fabric with supatex fabric.
4) use the fluffing pin from fabric one side acupuncture duplexer, the fluffing of first fiber is set on the surface of supatex fabric.
5) do not have nappy duplexer with the heating of 100-170 ℃ temperature, fusion second fiber makes between first fiber bondingly mutually, and the fiber of winning is bonded on the supatex fabric.
Described filler is a kind of ionic enzymatic polymer fiber filler.Described wetting ability superpolymer polyethylene alcohol can replace with polyacrylamide.Described wetting ability superpolymer polyethylene alcohol can replace with the mixture of the pure and mild polyacrylamide of wetting ability superpolymer polyethylene.The rugosity of described first fiber was 40～400 dawn.The rugosity of described second fiber was 3～20 dawn.The weight of the supatex fabric of described bottom is 20-600g/m2.
The invention has the advantages that: the principle that can utilize different electric charge to inhale mutually effectively improves the affinity of filling surface and microorganism, accelerates the microorganism rate of adsorption of filling surface; Filling surface is rich in the ionic enzyme, has the enzymatic effect, and effectively catalysis microorganism growth and reproduction speed have accelerated to improve the speed of microorganism concn, have effectively improved the effect of sewage disposal.
