Abstract
The lipophobic filtering material preparing process includes the following steps: 1. washing ceramic filter ball of 3-5 mm granularity in water and stoving to obtain ceramic filter material; 2. compounding modifying solution with no-benzene eco-friendly paint, curing agent and diluent in the volume ratio of 1 to 0.5-0.8 to 0.6-1, and through mixing; and 3. soaking the ceramic filter material inside the modifying solution through stirring at room temperature and drying naturally to obtain the lipophobic filtering material. Thus obtained lipophobic filtering material has the features of high oil eliminating rate, easy cleaning, high mechanical strength and long service life.
Description
Technical field
The present invention relates to a kind of preparation technology of oleophobic property filtrate.
Background technology
Oily waste water treatment process commonly used is at present: oil removal one coagulation (air supporting) filters.Wherein air supporting is to utilize particular device, under certain pressure with air dissolves in water, preparation meets the dissolved air water of air supporting requirement; In oily waste water, feed the dissolved air water that contains a large amount of micro-bubbles again, utilize micro-bubble to catch and adhere in the waste water and take off steady little oil droplet, form whole proportion less than the buoyancy aid of water and rely on buoyancy to float to obtain to the water surface oil, moisture from a kind of method, but conventional press dissolved air flotation treating apparatus is scraped the slag residue extraction mechanism and is constituted by air compressor, pressure air-dissolving jar, decompression release device, flotation tank, machinery, equipment is many, long flow path, volume is big.
Summary of the invention
The object of the present invention is to provide that a kind of deoiling effect is good, the preparation technology of the sparse oil porous ceramic filtering material of easy cleaning, mechanical strength height, long service life.
To achieve these goals, technical scheme of the present invention is: a kind of preparation technology of sparse oil porous ceramic filtering material is characterized in that it comprises the steps:
1) be that the ceramic filtration ball of 3～5mm is scrubbed with clear water with particle diameter, then 100～110 ℃ of oven dry down, pretreated ceramic filter material;
2) preparation modified solution: press no benzene ecological paint: curing agent:: no benzene ecological paint, curing agent and diluent are chosen in the volume ratio of diluent=1: 0.5～0.8: 0.6～1, curing agent is mixed with no benzene ecological paint, add diluent after stirring again, after fully stirring once more, get modified solution; Described curing agent is PIC or polyamide, and described diluent is butyl acetate or acrylate monomer;
3) pretreated ceramic filter material is joined in the modified solution, the addition of pretreated ceramic filter material is as the criterion so that pretreated ceramic filter material is just wetting, at room temperature stirs, and spreads out then, after the air dry, gets sparse oil porous ceramic filtering material.
Described ceramic filtration ball is a Chinese invention patent number: ZL200310111209.7 (inventor: Wu Jianfeng) the enviroment protective ceramic filter bulb of manufacturing.
The invention has the beneficial effects as follows: by to hydrophilic ceramic filtration ball (Chinese invention patent number: the enviroment protective ceramic filter bulb of ZL200310111209.7 manufacturing) carry out modification, make hydrophilic ceramic filtration ball become oleophobic property filtrate (being sparse oil porous ceramic filtering material).The sparse oil porous ceramic filtering material of the present invention's preparation is applied to the coarse of oily waste water, one side can be agglomerated into big particle diameter oil droplet with the dispersed oil of oil emulsion through taking off steady (polyaddition aluminium chloride) processing and small particle diameter and remove, thereby increase the clearance (clearance that does not have the ceramic filtration ball of modification under same experiment condition is 22.8%, and the oil removal rate of the sparse oil porous ceramic filtering material after the modification is 66.67%) of oil; Tackle the suspension of big particle diameter on the other hand by machinery, thereby alleviated the load of follow-up technology of fine filtering effectively.[use the clear water backwash, intensity is 20L/ (m to the sparse oil porous ceramic filtering material easy cleaning simultaneously
2S), the backwash time is 15min], mechanical strength higher (crushing strength is 18.2MPa), long service life (minimum) more than 1 year.
The coarse technology of using the sparse oil porous ceramic filtering material of the present invention's preparation and forming, technology is simple, and is applied widely, all can adopt oily waste water.
