Description
Technical field
The present invention relates to a kind of roadbase compound, especially, it is related to using special soil body stabilizing agent recycling treatment
The roadbase mixing of municipal sludge manufacture.
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.
Existing road building technology, constructs roadbase（Upper and lower basic unit, underlayment）All it is with graded broken stone（Primary rock
Stone, through broken, screening composition graded broken stone）It is material of main part, then lime is mixed by match ratio, flyash, cement, is made " two
Ash broken stones " or " cement stabilized grading crushed stones ", as the material for constructing roadbase.The major defect of this technology, is destruction
Ecological environment（Fried mountain takes stone or digs river and takes stone）, largely consume Resources and cost be too high.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of special soil body stabilizing agent recycling treatment municipal sludge
The roadbase compound of manufacture, the roadbase compound prepares primary compound, 3-8 of the material by 100 weight portions
The soil body stabilizing agent composition of the cement of weight portion and 0.01-0.1 weight portions, the primary compound by 100 weight portions city
Political affairs wet mud, the quick lime of 15-20 weight portions and solid waste composition, the soil body stabilizing agent is by 100 weight portions
Water, the surfactant of 1-15 weight portions, boric acid or the borate composition of 0.1-10 weight portions, the consumption of the solid waste
It is 7-13 times of municipal wet mud and the mixed cumulative volume of quick 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 porous calcium silicate for preparing material also including 1-5 weight portions and 0.01-0.5 weight portions to ammonia
Base salicylic acid.
Due to containing substantial amounts of heavy metal in municipal sludge, relative to the heavy metal that other are originated, the weight in municipal sludge
The dissolution of metal is more easy, can effectively reduce municipal sludge roadbase heavy metal using above-mentioned scheme, especially zinc
Dissolution.
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.
Existing road building technology, constructs roadbase（Upper and lower basic unit, underlayment）All it is with graded broken stone（Primary rock
Stone, through broken, screening composition graded broken stone）It is material of main part, then lime is mixed by match ratio, flyash, cement, is made " two
Ash broken stones " or " cement stabilized grading crushed stones ", as the material for constructing roadbase.The present invention is only with municipal sludge powder conduct
The material of main part of roadbase compound, takes full advantage of municipal sludge.The road that disposal of resources municipal sludge is prepared
Basic unit meets the requirement of national standard.
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.
Optimum moisture content of the invention refers to that compound reaches measured during maximum dry density indoors under compaction test
Water content is optimum moisture content, and due to the presence for having cement, optimum moisture content can be converted using filler optimum moisture content.
Optimum moisture content can be obtained by actual tests.
It is the soil body stabilizing agent of main body that the present invention uses boric acid or borate, substantially increases municipal sludge non-active ingredient
Crosslinking active, coordinate with a small amount of cement, the roadbase compound being prepared from meets the relevant criterion of country.
Those methods that the forming method of roadbase compound of the invention can be commonly used using other prior arts are entered
Row shaping.The method that the present invention is mixed using two benches, the particle diameter after the crushing of municipal sludge is 0.1-3mm, works as municipal sludge
Level is unfavorable for obtaining more preferable compression strength with powder particle size more than 3mm.The method mixed using two benches can improve unburned
The mechanical strength of brick.Compared with being mixed together, the compression strength of roadbase 10%-25% or so can be improved.
