Description

A kind of sewage treatment ceramic foam filter and preparation method thereof
Technical field
The present invention relates to a kind of ceramic material and arts, specifically a kind of sewage treatment ceramic foam filter and Preparation method.
Background technique
The foam of general sewage treatment is all that common foam sponge is put into treatment tank, is held after a certain period of time It easily causes foam to block, influences wastewater treatment efficiency, replacement foam not only wasted time, but also increased entreprise cost, but also can make At the secondary pollution for the treatment of tank.
Currently, domestic sewage water filtration mainly uses flat ceramic filter, penetrating amount, specific surface area are smaller, filtering effect Fruit is poor.And foam ceramic filter material has preferable penetrating amount, biggish specific surface face compared to flat ceramic filter Product more preferably intercepts adsorption filtration effect, and therefore, foam ceramic filter material is mainly used for various smelting non-ferrous metal castings Purification, however, when doing foamed ceramics presoma using polyurethane foam sponge, it is desirable to which sponge has three-dimensional netted more The shape in hole, it is desirable that there is sponge itself preferable elastic property, higher tensile strength, high through-hole rate and good slurry to inhale Attached performance.This is because sponge plays two important roles in the production process of foamed ceramics: first is that hanging Effect, in the process, sponge need the elastic property having had；Because when ceramic slurry is evenly distributed to sponge by roll-in When on channels and collaterals and node, sponge needs to bear slurry specific gravity bring gravity；If elasticity is bad, ceramic body be will be unable into Type.Second is that the effect of skeleton, dried foamed ceramics green body will finally be put into high temperature firing in kiln, in sintering process, Sponge can slowly melt with being stepped up for temperature；If melting process is too fast or sponge itself heat resistance is inadequate, all It will lead to ceramic body to collapse or seriously crack, so needing reticulated polyurethane foam that there is good presoma effect.
There are many preparation process of foamed ceramics, such as add pore creating material technique, foam process, Foam dipping method, molten Glue-gel process, solid granulates sintering process etc., wherein foam process and Foam dipping method are to prepare high porosity The effective ways of porous ceramics generally reach 50 μm -500 μm with foamed ceramics aperture prepared by both methods, but it is anti-to foam The shortcomings that answering method is to ingredient requirement height, and process conditions are not easy to control.
Summary of the invention
The present invention is provided and a kind of prepares simple, percent opening to solve above-mentioned existing deficiencies in the technology High, intensity height, sewage treatment ceramic foam filter at low cost and preparation method thereof.
The present invention provides a kind of sewage treatment ceramic foam filters, including polyethers to filter sponge and be attached to polyethers The ceramic material on sponge is filtered, the ceramic material is by various ceramic raw materials with special formula combination and special processing work Skill is made, and the ceramic material is made of the composition of raw materials of following mass fraction:

The water of 15%-20%；
The degumming agent of 0-1%.
The present invention also provides a kind of preparation methods of sewage treatment ceramic foam filter, comprising the following steps:
It 1) is the common black mud of 10%-20% by mass fraction, the stone of the potassium albite of 25%-35%, 20%-30% English, the wollastonite of 2%-5%, the calcined kaolin of 30%-40%, the negative ion powder of 1%-2%, the water of 15%-20%, 0- 1% degumming agent is added to quick stirring dispersion machine and stirs the slurry for being formed with certain viscosity, wherein the control of slurry fineness exists 325 mesh are tailed over less than 0.5%, specific gravity control in 1.9-2.0g/cm3, viscosity control is in 2000-2200mPas；
2) choosing mass fraction is the nano-anatase titanium dioxide of 2%-10%, the low viscosity resin of 15%-43%, 0- The water of 5% hyper-dispersant, 50%-60%, is added to quick mixer, and ultra-dispersed liquid coating is made in stirring 2h；
3) slurry of certain mass in step 1) is taken, the PVA glue that mass fraction is 5%-20% is added and is made to have and glues Property and mobility slurry, choose polyethers filtering sponge be sufficiently impregnated in above-mentioned slurry, dipping completely after, with three-wheel to roller Machine squeezes additional size, obtains the uniform foamed ceramics green body of immersion coating；
4) the foamed ceramics green body in step 3) is stood at 20-30 DEG C 2-3h, is then placed in constant temperature and humidity drying case Dry, drying time is determined by foamed ceramics size and thickness；
5) the foamed ceramics idiosome after will be dry in step 4) is put into roller kilns kiln, and 3h is fired at 1200 DEG C, is fired At with good adsorption properties, the uniform foamed ceramic carrier of mesh；
6) by the foamed ceramic carrier after firing be immersed in the ultra-dispersed coating in step 2) it is primary after, in freeze-day with constant temperature 200 DEG C of drying 2h, repeat impregnation steps 1 in case) in slurry is primary and 200 DEG C of drying 2h in thermostatic drying chamber, dry Product afterwards is burnt with the heating rate of 10 DEG C/min to 450 DEG C in shuttle-type electric furnace, and then natural cooling, is prepared into sewage treatment Use ceramic foam filter.
Further, the PVA glue solid content in step 3) is 15%.
Compared with prior art, the sewage treatment obtained by the present invention has three-dimensional with ceramic foam filter uniform pore diameter Space network possesses preferable filtering and intercepts performance；Pore size can according to cavernous body aperture adjustment to micron order, tool There is high penetrating amount；The ceramic foam filter is resistant to 800-1100 DEG C of high temperature, can be by making repeatedly after high-temperature heat treatment With cost is relatively low；In addition, the material property of ceramic grid itself can endlessly generate a large amount of anions, have preferable Adsorptivity, ion-exchange capacity and photo-catalysis capability make ceramic foam filter have good sterilization, deodorization, detergent power While, it also reduces ordinary flat ceramic filter plate and is easy the series of problems such as blocking, production cost height, greatly improve at sewage Efficiency is managed, is a kind of ideal sewage treatment purifier；In addition, sewage treatment of the invention ceramic foam filter preparation side Method uses Foam dipping method, and simple operations are feasible, and the ceramic foam filter of preparation is not easy get dirty water erosion, stability It is higher, secondary pollution will not be generated to water body.
