Abstract
The invention relates to a brick making method for sludge of a sewage treatment plant. The method comprises the steps: (1) subjecting the sludge of the sewage treatment plant to ultrasonic wave radiation for 30 to 90 minutes, wherein the sound energy density of ultrasonic waves is 0.5w/mL to 3w/mL; (2) mixing the radiated sludge, coal cinder, crushed construction waste and wood sawdust according to the volume ratio of 10: 5: 3: 1, and carrying out stirring, so as to obtain a brick making raw material; (3) preparing unburnt bricks from the brick making raw material through die pressing; (4) roasting the unburnt bricks at the roasting temperature of 700 DEG C to 800 DEG C under the condition that the degree of vacuum is smaller than 0.1, thereby obtaining finished bricks. The method is not only environmentally friendly, but also 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 water of crystallization）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 is disposed by cement plant, but its amount of clearing up is far from meeting yield.
In being full of 80% moisture content in the sludge of sewage treatment plants, big portion is the also difficult crystallization evaporated of exposure in the sun
Shape water body, even if being exposed to the sun can only also dissipate a small amount of crystalloid water body, and the town domestic sewage factory to moisture content up to 80%
Sludge is its moisture content of reduction（Even if by 80% to 60% moisture content）, the energy needed for which 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 ultrasound wave is 0.5w/mL-3w/
mL；
2）Building waste, wood flour by the sludge after radiation and cinder, after crushing presses 10:5:3:1 volume ratio carries out mixing and stirs
Mix and obtain brick-making raw material；
3）Brick-making raw material is pressed into 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, antibacterial, parasitic ovum, synthesis of organic substance etc. in sludge.
The present invention kills the antibacterial in sludge by ultrasound wave, eliminates virus, decomposes the material for producing foul smell, so as to eliminate the root of foul smell
Source, kills algae, eliminates float, improves the resolvability of COD, can be effectively prevented the propagation of pathogen.The present invention is logical
To cross sludge, sludge water of crystallization is mixed into cinder, building rubbish
Densification is combined in rubbish with sludge, and brickmaking is carried out by roasting, the sludge of sewage treatment plant can be made full use of, prevent which from causing
Environmental pollution, will not produce secondary pollution again.
In addition, add wood flour in sludge, can make obtained finished bricks that there is higher porosity, improve obtained in build
Build the heat insulation effect of thing.
Roasting under vacuum, has 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）The steam that evacuation is obtained is allow to be sufficiently used for generating electricity or take
Warm up, environmental protection.
Preferably, the wood flour is fallen leaves by straw, branch, waste wood furniture is broken makes.
Preferably, step 3）In make adobe after, by adobe be placed in 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 ultrasound wave is 0.5w/mL-3w/
mL；
2）Building waste, wood flour by the sludge after radiation and cinder, after crushing presses 10:5:3:1 volume ratio carries out mixing and stirs
Mix and obtain brick-making raw material；The wood flour is fallen leaves by straw, branch, waste wood furniture is broken makes.
3）Brick-making raw material is pressed into into adobe by mould, then adobe is placed in 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.
