The present invention also provides the method for the flyash composite filter material described in preparation, comprises the following steps:
1) first soaked with clear water in sedimentation basin by flyash, removing surface dust, pull flyash out, draining dries;
2) flyash of step 1) process is added obtained fly ash grain in comminutor;
3) to step 2) add atlapulgite, silica and silicate in described ratio in the fly ash grain that obtains and prepare hybrid particles;
4) be dispersed in water by the hybrid particles that step 3) obtains, the addition of water accounts for the 15%-20% of total quality of material, forms solution, add expanding agent, be uniformly mixed rear dropping ethyl orthosilicate, reaction 3-5 hour, filter, vacuum drying obtains preliminary composite filter material;
5) preliminary composite filter material step 4) obtained is dried and is removed moisture, then roasting 3-4 hour at 200-250 DEG C in 3-5 hour at 120-160 DEG C, i.e. obtained described flyash composite filter material.
Expanding agent described in step 4) is preferably 3,4,5-trimethoxybenzoic acid, and addition is 2% of described liquor capacity.
Ethyl orthosilicate addition described in step 4) is preferably 0.5% of described liquor capacity.
The present invention also provides described flyash composite filter material as the application of water treatment agent in sewage purification.
In composite filter material obtained by the inventive method, flyash forms the particle that particle diameter is less than 6 millimeters, described atlapulgite, silica and silicate are wrapped in the surface of flyash and through sintering the porcelain layer forming adsorptivity micropore, therefore flyash composite filter material of the present invention is a kind of surperficial porcelain and has the material of a large amount of hole.Compared with prior art, flyash composite filter material of the present invention has following several respects beneficial effect:
1. composite filter material of the present invention has the adsorptivity of flyash and the adsorptivity of micropore thing simultaneously, and has flocculability.The active material of flocculating property is solidificated in micropore, can slow releasing, and make the oxidized degraded of pollutant be adsorbed in micropore, the shortcoming of luxus consumption flocculant when avoiding disposing of sewage, can save the consumption of flocculant.
2. composite filter material of the present invention, is fired by flyash, silicate and atlapulgite compound and forms, have triplen, polluter is had to the effect of adsorption-decomposition function simultaneously, significantly enhance the pollutant disposal ability of flyash.
3. the technique prepared of composite filter material of the present invention is simple, and can not produce secondary pollution.
4. combined filtration process range of the present invention is wide, can integrated treatment municipal sewage; Treatment effect is good, and removal efficiency is more than 99%, and the flco of generation is few, and precipitation is fast.
