Abstract
The invention relates to a brick making method using sludge of a wastewater treatment plant. The method comprises: 1) radiating sludge of a wastewater treatment plant with supersonic wave for 30-90 min, wherein the sound energy density of the supersonic wave is 0.5-3 w/ml; 2) performing mixing and stirring of radiated sludge, coal slag and pulverized building garbage according to a volume ratio of 10:5:3 to obtain a brick making raw material; 3) pressing the brick making raw material with a die to prepare a brick blank; and 4) roasting the brick blank in a condition with the vacuum degree less than 0.1 and the roasting temperate being 700-800 DEG C to obtain a final brick product. The method is green and eco-friendly and is high in brick making efficiency.
Description
Technical field
The present invention relates to a kind of brick-making method of sludge of sewage treatment plant, belongs to technical field of municipal refuse treatment.
Background technology
A large amount of sanitary sewage disposals are filled out in current city --- precipitating sludge Jing after pressure, filter predrainage moisture content still 60-85% it
Between（Containing the crystallization water）Sludge silt because wherein containing the harmful substance such as heavy metal, various places government forbids to fill on the spot, though it is useful
Chemical method dehydration fed to boiler is burned or disposed by cement plant, but its amount of clearing up is far from meeting yield.
It is the also difficult crystallization evaporated of exposure in the sun to be full of big portion in 80% moisture content in the sludge of sewage treatment plants
Shape water body, even if be exposed to the sun can only also dissipate a small amount of crystalloid water body, and is up to 80% town domestic sewage factory to moisture content
Sludge is its moisture content of reduction（Even if by 80% to 60% moisture content）, its required energy is seriously to lose more than gain with the input of fund
, and secondary pollution is also extremely difficult avoids.Therefore, disposal and the recycling of reasonable environmental protection how are carried out to sludge, is very
Big problem.
The content of the invention
The invention solves the problems that technical problem is：Overcome the shortcoming of above-mentioned technology, there is provided a kind of brick-making method of environmental protection.
In order to solve above-mentioned technical problem, technical scheme proposed by the present invention is：A kind of brickmaking of sludge of sewage treatment plant
Method, comprises the following steps：
1) by the sludge of sewage treatment plant by Ultrasonic Radiation 30-90 minutes, the acoustic density of ultrasonic wave is 0.5w/mL-3w/
mL；
2）Building waste by the sludge after radiation and cinder, after crushing presses 10:5:3 volume ratio carries out mixing system
Brick raw material；
3）Brick-making raw material is pressed into adobe by mould；
4）Adobe is carried out into roasting under conditions of vacuum is less than 0.1, sintering temperature is 700-800 DEG C, obtains finished bricks.
Contain substantial amounts of poisonous and harmful substance, such as pathogenic microorganism, bacterium, parasitic ovum, synthesis of organic substance in sludge.
The present invention kills the bacterium in sludge by ultrasonic wave, eliminates virus, decomposes the material for producing foul smell, so as to eliminate the root of foul smell
Source, kills algae, eliminates suspension, improves the resolvability of COD, can be effectively prevented the propagation of pathogen.The present invention is logical
Crossing sludge after Ultrasonic Radiation carries out manufacturing bricks by mixing with cinder, building waste, and the sludge crystallization water is mixed into cinder, building rubbish
Densification is combined with sludge in rubbish, and brickmaking is carried out by roasting, the sludge of sewage treatment plant can be made full use of, prevent it from causing
Environmental pollution, will not produce secondary pollution again.
Roasting under vacuum, there is following advantage：1）The more conventional method of sintering temperature is reduced；2）Improve brickmaking effect
Rate is improved, and moisture easily evaporates, and accelerates brickmaking speed；3）Allow to vacuumize the steam for obtaining and be sufficiently used for generating electricity or take
Warm up, environmental protection.
Preferably, step 3）In make after adobe, by adobe be placed into drying hole concentrate humidity discharging be dried.
Specific embodiment
Embodiment
The brick-making method of the sludge of sewage treatment plant of the present embodiment, comprises the following steps：
1) by the sludge of sewage treatment plant by Ultrasonic Radiation 30-90 minutes, the acoustic density of ultrasonic wave is 0.5w/mL-3w/
mL；
2）Building waste, wood chip by the sludge after radiation and cinder, after crushing presses 10:5:3 volume ratio is mixed
Obtain brick-making raw material；
3）Brick-making raw material is pressed into adobe by mould, then adobe is placed into drying hole and is concentrated humidity discharging to be dried；
4）Adobe is carried out into roasting under conditions of vacuum is less than 0.1, sintering temperature is 700-800 DEG C, obtains finished bricks.
The present invention is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the present invention may be used also
To there is other embodiment.The technical scheme that all employing equivalents are formed, is the protection domain of application claims.
