Description
Technical field
The invention belongs to industrial solid wastes innoxious use technical field, particularly a kind of is raw material production environmental protection brick and preparation method thereof with municipal sludge and industrial sludge.
Technical background
Mud is that industry and sanitary sewage produce, and wherein contains hazardous substancess such as large amount of organic and heavy metal, and is difficult to decompose and absorb under natural environment, easily produces secondary pollution.The recycling sludge utilization has been become the environmental problem that present urgent need solves.At present recycling sludge utilizes mode to mainly contain: agricultural, producing building material, heat energy utilization, produce active carbon etc.
Chinese patent publication number CN101219887A, an open day 2008.07.16, the name of innovation and creation is called " preparation method of municipal sludge brick and municipal sludge brick ", and to disclose with municipal sludge and shale powder be primary raw material, through moulding with fire and form.Various proportion of raw materials scopes are 30 parts of municipal sludges; Shale powder 40-80 part, preferred 55-65 part; Alundum (Al 0-5 part, preferred 2-4 part; Di-iron trioxide 0-4 part, preferred 1-3 part; Calcium oxide 0-8 part, preferred 4-6 part.The invention still further relates to a kind of preparation method of municipal sludge brick, it adopts the various raw materials of above-mentioned municipal sludge brick, after various raw materials are added water and mix, makes half-finished adobe, and adobe is dried and roasting, forms the finished product of brick.
Chinese patent patent publication No. CN101318805A, open day 2008.12.10, the name of innovation and creation is called " utilizing municipal sludge and wet-discharged coal ash to produce the method for sintering brick permeable to water ", and to disclose method step as follows: (1) presses municipal sludge 30～50%, wet-discharged coal ash 45～65%, pore creating material 3～10%, mix, control mixes mixes moisture content about 18%; The material input hydraulic pressure formula that (2) will mix or extrude brickmaking machine, the moulding adobe; (3), the adobe moisture content is reduced to below the 6%c by air dry or utilize using residual heat from kiln furnace that drying is carried out in adobe; (4) dried adobe is sent in the kiln 1050～1180 ℃ of roastings of high temperature and promptly burnt till finished product in 3～4 hours.
The open day 2008.09.03 of Chinese patent publication number CN101255050A, the name of innovation and creation is called " method of sintering bricks by high-doping aluminium hydroxide industrial sludge clay ", it is as follows to disclose this method step: the dehydration of 5-15% aluminium hydroxide industrial sludge, and 85-95% adds clay and mixes, the 0.1-0.15% reinforcing agent of two kinds of raw material total amounts, adjust humidity 12～16%, adjust Acidity of Aikalinity 6.5～8, mix and stir 5～10min, moulding, be dried to moisture content to 1～5%, 900-1020 ℃ of roasting.
Above-mentioned present technology discloses the certain methods of handling various mud, and core technology content wherein is proportion of raw materials and sintering temperature.For different raw materials, may take different proportionings and sintering temperature to reach each target effect.But it is exactly that the heavy metal of the finished bricks produced leaches toxicity and remains conclusive that said method all has a tangible deficiency.
Summary of the invention
Technical problem to be solved: the present invention is directed to the prior art deficiency, provide and adopted the effective curing heavy metal ion of curing compound in a kind of its component, make heavy metal leach low sludge brick of toxicity and preparation method thereof.
Technical scheme: sludge brick of the present invention is characterized in that its component and content are:
Mud 30%～40%, curing compound 10%～20%, flyash 15%～25%, clay 5%～15%, industrial residue 0%～10%, all percentages are mass percent.
Preferably, mud 38%, curing compound 18%, flyash 23%, clay 13%, industrial residue 8%.
Described mud is municipal sludge or industrial sludge or its both mixtures, and curing compound is a portland cement, and it is pyrite slag or aluminium sulfate slag or aluminium chloride slag that the worker comes waste residue.
The preparation method of sludge brick of the present invention is:
(1) with mud, curing compound, flyash, clay, industrial residue stirs in mixing plant;
(2) the said mixture material is crushed to the adobe of difformity and size with fluid pressure type or extruded type brickmaking machine;
(3) air dry or utilize the roasting using residual heat from kiln furnace that drying is carried out in adobe makes the adobe moisture content below 15%;
(4) dried adobe was got product with 900 ℃～1100 ℃ high temperature sinterings in 2～3 hours.
The present invention compared with prior art has following advantage:
The present invention is a technology of handling other industrial residue such as flyash in a large number, and it is innoxious mainly to solve municipal sludge, industrial sludge and other industrial residue, problem of complex utilization.Adopt the effective curing heavy metal ion of curing compound, it is low that heavy metal leaches toxicity.The raw material that production environmental protection brick adopts not only can be a municipal sludge but also can be industrial sludge, can handle other industrial residue again, not only effectively reduces cost, and plays the purpose of protection environment.Need not mud is carried out processed, have heat-insulating property because of in the sinter process, forming internal void.Production technology is simple, and cost is low, has good economic benefit and environmental benefit.
