Description
Technical field
The present invention relates to a kind of manufacture method of material of construction, be specifically related to the method that a kind of municipal sludge is made floor tile.
Background technology
Along with the quickening of Urbanization in China, treatment rate of domestic sewage improves year by year, and the number of municipal sewage plant and sludge yield also increase thereupon.At present, the sludge quantity (dry mass) of the annual discharging in China municipal sewage plant is about 1,300,000 t, and increases rapidly with the speed of annual growth 10%.The mud pollutent has long term toxicity and non-biodegradable, if let alone unordered discharging, will become dangerous secondary pollution source, enters food chain by media such as atmosphere, underground water, surface water and soil, and serious threat is to human health.Therefore, how properly to dispose municipal sludge, become the problem of domestic and international extensive concern.At present, be one of important channel of city sewage sludge reclamation with sludge incineration ash as the spike of vitrified brick, but because its production process energy consumption is excessive, required high cost is not promoted effectively in China so far.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing municipal sludge to produce excellent property, energy-conserving and environment-protective, floor tile that cost is low.
A kind of municipal sludge is made the method for floor tile, may further comprise the steps:
(1) be that municipal sludge more than 80% adds and to be equivalent to the unslaked lime of mud weight 28-35%, the plant ash mixing and stirring of 5-8% with water ratio, ageing was deposited 7-10 days, made its water ratio≤60%;
(2) municipal sludge with water ratio≤60% is sent in the agitator through conveying belt, add stalk coatedparticles, cement slurry, river sand, alum ore deposit tailings, potter's clay, modified meerschaum, volcanics, zeolite, coconut husk charcoal to agitator simultaneously, be stirred into the mixing pug under the 150-200r/min rotating speed, wherein the weight part of each raw material is as follows: municipal sludge 50-60, stalk coatedparticles 5-8, cement slurry 5-10, river sand 14-16, alum ore deposit tailings 12-15, potter's clay 8-10, modified meerschaum 3-5, volcanics 10-15, zeolite 15-25, coconut husk charcoal 5-10;
(3) the above-mentioned compound that makes is stacked ageing 2-3 days;
(4) mud after the ageing is carried out pugging after, send into brick press, by extruding be cut into adobe;
(5) the moulding adobe is piled up neatly, after drying in the shade 3-5 days under the natural condition, at 105-120 ℃ of lower forced air drying 20-24h, making its water ratio is 10-15%;
(6) send into the stove sintering, sintering temperature is 1020-1040 ℃, grill thoroughly adobe after, be cooled to the room temperature kiln discharge brick that gets product.
Described stalk coatedparticles is made by the raw material of following weight part: wilkinite 20-30, plant straw powder 18-24, water glass 20-25, carboxymethyl cellulose 0.5-1, clay 5-8; Preparation process is as follows: will add in the high-speed mixer with carboxymethyl cellulose after the wilkinite drying; speed with 500-800rpm under 110-120 ℃ mixes 20-30min; after adding again water glass continuation stirring 10-15min; then add plant straw powder, clay with the speed blend 5-10min of 1000-1500rpm; send into granulation in the tablets press after the oven dry; particle diameter is controlled at 2-4mm, namely gets the stalk coatedparticles.
Described modified meerschaum is prepared by following method: place 400-450 ℃ of kiln roasting 2-3h, pulverize and grind to form 100-150 order powder, namely get modified meerschaum behind the porphyrize.
Beneficial effect of the present invention:
The present invention utilizes plant straw powder to coat wilkinite by to formula adjustment and process modification, can obviously improve water tolerance and the intensity of floor tile; Sepiolite is carried out modification, can improve the adsorptivity of the objectionable impuritiess such as its obnoxious flavour that floor tile is discharged in use, heavy metal.The produced floor tile of the present invention has light weight, intensity is large, water-tolerant, not yielding, the advantages such as safety nuisance free, environmental protection and energy saving.The inventive method is simple, and is easy to operate, and raw material sources are extensive, with low cost, and save energy has reduced any discharging of municipal sludge, has good Social benefit and economic benefit.
