Description
Technical field
The present invention relates to field of Environment Protection, in particular it relates to using special soil body stabilizing agent recycling treatment municipal sludge system
That makes is non-burning brick.
Background technology
Municipal sludge refers to the clod or mud cake of discharge after the concentrated dehydration in municipal sewage plant, and general moisture content exists
80% or so, and containing nutrients such as abundant organic matters and N, P, K, also contain the nuisance such as heavy metal and pathogen
Matter, if mishandling, not only easily causes environmental pollution, also can waste of resources is caused.With China's economy and urbanization
Fast development, the generation of municipal wastewater and its quantity are sharply increased.
With being further exacerbated by for urbanization, the municipal sludge of China is more and more, is badly in need of a kind of new technique and technology,
So that municipal sludge obtains disposal of resources.
The content of the invention
In order to solve the above problems, special soil body stabilizing agent recycling treatment municipal sludge is used the invention provides one kind
Manufacture it is non-burning brick, it is described it is non-burning brick prepare material by the primary compound of 100 weight portions, the cement of 5-10 weight portions and
The soil body stabilizing agent composition of 0.01-0.1 weight portions, municipal wet mud, 15-20 weight of the primary compound by 100 weight portions
Measure part quick lime and solid waste composition, the soil body stabilizing agent by 100 weight portions water, the table of 1-15 weight portions
Face activating agent, boric acid or the borate composition of 0.1-10 weight portions, the consumption of the solid waste is municipal wet mud and life
7-13 times of the mixed cumulative volume of lime.
The moisture content of the municipal wet mud is 70-85%.
The cement is 425# Portland cements.
The pH value of the soil body stabilizing agent is adjusted to 8-10.
The solid waste is one or more in metal tailings, industrial residue, building waste.
The surfactant is butyl naphthalene sulfonate.
Surfactant of the invention can be adsorbed in the surface of bulky grain, change the hydrophily of particle surface so that
Grain has the effect of shield water, reduces the water imbibition of particle, and what is prepared is non-burning brick with good permeability resistance, and then has
There is good compression strength.Present invention employs a small amount of cement, boric acid or borate are added, substantially increased non-burning brick
Compression strength, employs soil body stabilizing agent of the invention, and the usage amount that can in large quantities reduce cement is unburned without reducing shaping
The compression strength of brick.
The non-burning brick material for preparing also includes terminal hydroxy group siloxanes and the 0.001-0.005 weight of 0.01-0.8 weight portions
Measure the curing agent of part.The curing agent is alpha-amido silane coupler, and terminal hydroxy group siloxanes, curing agent and soil body stabilizing agent are simultaneously
Add to the second blending bunker.Using the solution of the present invention prepare it is non-burning brick be destitute of smell substantially, because sludge contains greatly
The organic matter of amount, and oxygen-containing ratio is high, such organic matter easily sends corruption and discharges stink.Present invention employs can
The terminal hydroxy group siloxanes of solidification can avoid mud organic substance that aminocarbonyl reaction occurs.
A kind of non-burning brick preparation method, comprises the following steps：
Municipal wet mud, the quick lime of 15-20 weight portions of 100 weight portions are added in the first blending bunker, sludge is mixed to get
Compound；
The solid waste of 7-13 times of sludge mixture volume is added in the first blending bunker, primary compound is mixed to get；
The primary compound is stacked 5-30 days；
The cement of primary compound, 5-10 weight portions after 100 weight portions are stacked mixes 3-15 minutes in the second blending bunker
Afterwards, the soil body stabilizing agent mixing of 0.01-0.1 weight portions 3-15 minutes is added, non-burning brick compound is obtained；
Compressing, natural curing under non-burning brick compound normal temperature is obtained into non-burning brick finished product.
Due to containing substantial amounts of harmful bacteria, heavy metal in municipal sludge, it is impossible to used as agricultural fertilizer source.This hair
It is bright directly to make non-burning brick using municipal wet mud, wet mud concentration, dewatering process are eliminated, high temperature sintering brickmaker is not used
Skill, cost is substantially reduced.Making obtain it is non-burning brick meet national standard requirement, excellent mechanical.
The above-mentioned of the application and other features, aspect and advantage is more readily understood with reference to described further below.
Specific embodiment
Unless otherwise defined, all technologies used herein and scientific terminology have and the common skill of art of the present invention
The identical implication that art personnel are generally understood that.When there is contradiction, the definition in this specification is defined.
Those methods that non-burning brick forming method of the invention can be commonly used using other prior arts are molded.City
Particle diameter after the crushing of political affairs sludge is 0.1-2mm, when municipal sludge level is unfavorable for obtaining more preferable resistance to compression with powder particle size more than 2mm
Intensity.The method mixed using two benches can improve non-burning brick mechanical strength.Compared with being mixed together, can improve and exempt from
Bake bricks the compression strength of 10%-25% or so.
