Description

A kind of preparation method of porous spherical environmental protection filtrate
Technical field
The present invention relates to a kind of preparation methods of porous spherical environmental protection filtrate.
Background technique
With the fast development of modern industry, the surge of population, energy problem is increasingly severe, meanwhile, environmental pollution Problem is also being further exacerbated by, and water resources crisis also has become a worldwide problem urgently to be resolved.With industrial or agricultural and The rapid development in city, the discharge of a large amount of pollutants, natural water decline by serious pollution, the utilization rate of water resource, The problem of even more exacerbating China's shortage of water resources.Pollution entering the water includes industrial pollution source, agricultural pollution source and domestic pollution source Three parts, and according to polluter difference, water pollution is broadly divided into chemical contamination, physical pollution and biologic contamination again Three categories.In recent years, the discharge amount of China's industrial wastewater and municipal wastewater is about 57,200,000,000 tons, and water pollution is processed into order to urgently Problem to be solved.Filtrate as processing waste water a kind of mode, at present mainly using glass reinforced plastic filtrate, plastic honeycomb filtrate, Stereo corrugated filtrate, soft fiber filtrate, irregular particulate filter etc..Glass reinforced plastic filtrate and plastic honeycomb filter material surface are smooth, Biomembrane poor adhesive force, it is easy to aging, and tend to generate different degrees of blocking in practical applications.Water in soft filtrate Stream mode is undesirable, is easily bonded together by biomembrane, generates balling phenomenon, greatly reduces its surface area, and then in balling Inside generates anaerobic effect, influences treatment effect.Irregular particulate filter resistance to water-flow is big, easily causes to block.China in recent years Also carried out and handled sewage using ceramic grain filter, but, but its resistance to water-flow is big, is easy blocking, therefore, researchs and develops novel filter Material is that new road is opened up in sewage treatment.
Summary of the invention
Technical problems to be solved: a kind of preparation method of porous spherical environmental protection filtrate, gained porous spherical environmental protection are provided Filtrate is for COD, BOD and NH4- N has extraordinary filter effect.
Technical solution: a kind of preparation method of porous spherical environmental protection filtrate, ingredient is by weight, comprising the following steps:
(1) by 5-10 parts of clays, 2-5 parts of polycrystalline mullite fibres, 2-5 parts of cow dung charcoals, 3-7 parts of silicon powders and 3-6 parts of barium Feldspar powder mixing, is ground to fineness < 0.1mm;
(2) plus water polo is milled to partial size≤5 μm, dries to obtain mixed powder;
(3) 5-10 parts of zasiokaurins and dehydrated alcohol are sufficiently mixed in the ratio that mass volume ratio is 1g:10-14mL, and Magnetic agitation effect is lower to wash 10h, in triplicate;
(4) filtration drying is soaked in 3-4h in 5% hydrochloric acid solution, is washed with deionized water to neutrality, is put into drying box, It is dried at 80-85 DEG C;
(5) it is equably laid on the ground electrode in low-temperature plasma processing unit, in supply frequency 8-10kHz, operating voltage 6-9min is handled under the conditions of 20kV, discharge power 70-80W obtains modified corn pollen;
(6) mixed powder, zasiokaurin, 5-10 parts of guar gums and 50-80 parts of deionized waters are mixed, in revolving speed 500-600rpm Lower stirring 1-2h;
(7) dry after filtering;
(8) it is put into silicon carbon rod electric furnace and is burnt into, the first stage: being warming up to 90-100 DEG C, keeps the temperature 60min;Second stage: it rises Temperature keeps the temperature 30min to 500-600 DEG C;Phase III: being warming up to 1100-1150 DEG C, keeps the temperature 30-40min;
(9) it is cooled to room temperature, coupling agent KH550 and deionized water is added, stir 20-30min;
(10) it filters, is put into porous spherical environmental protection filtrate obtained by drying in baking oven.
Further, the cow dung charcoal the preparation method comprises the following steps:
Step 1: take cow dung, picks and carry out after the sundries such as stone air-dried, be crushed to partial size less than 20 mesh;
6h is carbonized step 2: being put into Muffle furnace, is taken out after being cooled to room temperature, 60 meshes are crossed;
Step 3: being washed with deionized water after filtering with salt acid elution 5 times of 1mol/L to neutrality;
Step 4: porous spherical environmental protection filtrate obtained by drying.
Further, the partial size of the porous spherical environmental protection filtrate is 150-200 μm.
Further, in the step (5) supply frequency be 7kHz, discharge power 75W.
Further, the first stage in the step (8): being warming up to 95 DEG C, keeps the temperature 60min;Second stage: being warming up to 550 DEG C, Keep the temperature 30min;Phase III: being warming up to 1130 DEG C, keeps the temperature 35min.
The utility model has the advantages that
1. joined cow dung charcoal, novel structure is introduced, increases surface area.
2. introducing completely new biological structure, while spherical surface area is big using zasiokaurin as biological template, filter effect is good.
3. generating intensive and uniform aperture after the processing of low-temperature plasma processing unit, filter effect is more preferable.
4. through porous spherical environmental protection filtrate prepared by the present invention for COD, BOD and NH4- N has extraordinary filter effect, After filtering, COD, BOD and NH4The amount of-N is all down to 25.9mg/L, 18.7mg/L and 1.07mg/L.
