Abstract
The invention discloses an inorganic curing agent. The inorganic curing agent is prepared from magnesium chloride, aluminum sulfate, calcium chloride and a naphthalene water reducer. The mass ratio of magnesium chloride to aluminum sulfate to calcium chloride to the naphthalene water reducer is 1:4:1:1. The inorganic curing agent is good in economic benefit, high in dewatering performance and large in flocculation sweeping effect, the compressive property of cured sludge can be greatly improved, the content of heavy metals of the sludge can be reduced, and heavy metal ions in the sludge can be hardly dissolved out.
Description
Technical field
The present invention relates to field of sludge treatment, more specifically, it relates to a kind of inorganic solidification agent and application thereof.
Background technology
China is the developing country that the whole world is maximum, populous, the problem of environmental pollution thus brought is on the rise, the acceleration of urbanization progress, urban infrastructure and the development construction item such as industry, real estate increasing, producing substantial amounts of building waste, the waste mud that wherein building pile foundation produces just seems especially prominent.Waste mud is the product after drilling well piling, is a kind of extremely complex heterogeneous body being made up of organic relic, microorganism, inorganic particle, colloid etc..Not only contaminated environment, destroys ecological balance, affects people's life, and consumes a large amount of manpower and materials.For Wenzhou City's Wenruitang river, government spends more than one hundred million unit's funds and substantial amounts of manpower to administer every year, but pollution of estuary situation does not still have basic change, along the river resident complaints are heard everywhere.Tracing it to its cause, thoroughly do not administered from source, the unrest discharge phenomenon of waste mud is comparatively serious.
The moisture content of sludge from wastewater treatment plant (abbreviation municipal sludge) is general all about 75%, and containing a large amount of hardly degraded organic substances, pathogenic microorganism, heavy metal, and nitrogen, phosphorus etc., serious secondary pollution can be caused if do not carried out dealing carefully with.At present, the Main Means of sludge treatment has compost, landfill, burning, Land_use change etc., wherein fills because of convenient operation and management, and operating cost is relatively low and is more adopted.But, municipal sludge soil mechanics intensity is unable to reach landfill requirement, and easily by rain drop erosion, the harmful substance such as heavy metal easily leaches in rainwater immersion process, therefore the safety of its landfill is under suspicion.
Therefore, no matter considering from the innoxious degree of perfection of pollutant, importance mud conditioning technology and ratio between investments, the process of mud is disposed and is all occupied highly important status.More existing patent proposes equipment and the method for efficient lignin-sludge at present, also has some to carry out the inorganic solidification agent processed, unprecedented a kind of Treatment of Sludge inorganic solidification agent for building waste and contaminated soil.Mud is carried out cured by cooperation ordinary cement and quick lime by this inorganic solidification agent, thus the safety of mechanical property native after improving solidification and raising soil.
Summary of the invention
For the deficiency that prior art exists, it is an object of the invention to provide a kind of Treatment of Sludge inorganic solidification agent, mud is carried out cured by cooperation ordinary cement and quick lime by this Treatment of Sludge inorganic solidification agent, thus the safety of mechanical property native after improving solidification and raising soil.
For achieving the above object, the technical scheme is that
A kind of inorganic solidification agent, described inorganic solidification agent consists of the following composition: magnesium chloride, aluminum sulfate, calcium chloride, how based water reducer；Described magnesium chloride, aluminum sulfate, calcium chloride, how based water reducer mass ratio 1: 4: 1: 1.
The application of above-mentioned inorganic solidification agent, its step is as follows:
A. in mud, add inorganic solidification agent, carry out stirring fully, flocculation；
B. the quick lime added, and carry out stirring fully and heat radiation；
C. add inorganic solidification agent again, it is sufficiently stirred for, flocculates；
D. remaining all of quick lime and ordinary cement are added, and be sufficiently stirred for, solidify.
The present invention is arranged further: described inorganic solidification agent, ordinary cement, quick lime, mud mass ratio 4: 1: 10: 60.
The present invention is arranged further: the mass ratio 1: 1 of the inorganic solidification agent in described step a and the inorganic solidification agent in step c.
The present invention is arranged further: the mass ratio 1: 1 of the inorganic solidification agent in described step b and the quick lime in step d.
The method have the benefit that inorganic solidification agent is to the solidification effect of mud clearly, dewatering is relatively good, the flocculation volume effect of sweeping is big, the solidification highly significant of heavy metal ion, certain economic benefit is also very high, and after this inorganic solidification agent coordinates cement and quick lime cured mud, its intensity can reach 1.8MPa, harmful leachable heavy metal ion is not enough original 0.1%, and heavy metal ion therein also can be made to be difficult to dissolution
Detailed description of the invention
It is described in further details with reference to embodiments of the invention.
A kind of inorganic solidification agent, described inorganic solidification agent consists of the following composition: magnesium chloride, aluminum sulfate, calcium chloride, how based water reducer；Described magnesium chloride, aluminum sulfate, calcium chloride, how based water reducer mass ratio 1: 4: 1: 1.
The application of above-mentioned inorganic solidification agent, its step is as follows:
A. in mud, add inorganic solidification agent, carry out stirring fully, flocculation；
B. the quick lime added, and carry out stirring fully and heat radiation；
C. add inorganic solidification agent again, it is sufficiently stirred for, flocculates；
D. remaining all of quick lime and ordinary cement are added, and be sufficiently stirred for, solidify.
Wherein: described inorganic solidification agent, ordinary cement, quick lime, mud mass ratio 4: 1: 10: 60.
The mass ratio 1: 1 of the inorganic solidification agent in wherein said step a and the inorganic solidification agent in step c；The mass ratio 1: 1 of the inorganic solidification agent in described step b and the quick lime in step d.
Wherein concrete order of addition is: a. first adds the inorganic solidification agent of need addition 50% in whole mud, carries out stirring fully, flocculation；B. add the quick lime that 50% needs add, and carry out stirring fully and heat radiation；C. add the inorganic solidification agent of 50%, also it is sufficiently stirred for, flocculate；D. remaining all of quick lime and ordinary cement are added, and be sufficiently stirred for, solidify.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
