Abstract
The invention discloses a kind of sludge curing agent, count by weight, its raw material includes：4 ~ 6 parts of ardealite, 15 ~ 18 parts of cement, 26 ~ 30 parts of quick lime, 7 ~ 9 parts of limestone, 28 ~ 32 parts of flyash, 1 ~ 2 part of hydroxypropyl methyl cellulose, 6 ~ 8 parts of glass-cermic powder, 6 ~ 8 parts of ceramic, 10 ~ 15 parts of furfural dregs, 4 ~ 6 parts of Maifanitum and 8 ~ 10 parts of smectite clay.The sludge curing agent of the present invention can significantly reduce the moisture content of high-moisture percentage mud, can effectively reduce the internal strain of mud after solidification, prevent from ftractureing, and solidification intensity is high, hardening time is short, enables to coagulate soon, hard soon；And can heavy metal in active adsorption curing sludge, reach the requirement that landfill and building are banketed.The sludge curing agent of the present invention has carried out recycling to mud, the problems such as solve the pollution environment caused by a large amount of siltations, energy-conserving and environment-protective, and low engineering cost, profitable.
Description
Technical field
The invention belongs to environmental technology field is and in particular to a kind of sludge curing agent and preparation method thereof.
Background technology
Natural sludge water content is high, and low intensity also contains some harmful components such as toxic chemical substance, causal organism, work
Journey poor performance, if without process, will cause very big pollution to environment.At present, domestic main employing sludge curing agent pair
Mud carries out cured, to reduce the moisture content of mud with this, improves the intensity of mud to meet the requirement that the earthwork is filled.Pass
The sludge curing agent of system（As Calx, cement, flyash etc.）Although improving in terms of intensity, hardening time is relatively
Long, solidification effect is inconspicuous, and soaking effect in a short time is poor.It would therefore be highly desirable to develop one kind can improve mud intensity, and
Water in mud can effectively be absorbed in a short time, improve the Novel curing agent of mud optimum moisture content.
Content of the invention
Present invention aims to prior art is not enough, provide a kind of sludge curing agent and preparation method thereof.
For achieving the above object, the present invention adopts the following technical scheme that：
A kind of sludge curing agent, counts by weight, and its raw material includes：4 ~ 6 parts of ardealite, 15 ~ 18 parts of cement, quick lime 26 ~
30 parts, 7 ~ 9 parts of limestone, 28 ~ 32 parts of flyash, 1 ~ 2 part of hydroxypropyl methyl cellulose, 6 ~ 8 parts of glass-cermic powder, ceramic 6 ~ 8
Part, 10 ~ 15 parts of furfural dregs, 4 ~ 6 parts of Maifanitum and 8 ~ 10 parts of smectite clay.
Preferably, a kind of sludge curing agent, counts by weight, and its raw material includes：5 parts of ardealite, 16 parts of cement, calculogenesis
28 parts of ash, 8 parts of limestone, 30 parts of flyash, 1.5 parts of hydroxypropyl methyl cellulose, 7 parts of glass-cermic powder, 7 parts of ceramic, furfural
12 parts of slag, 5 parts of Maifanitum and 9 parts of smectite clay.
Described ardealite adopt secondary standard and more than, wherein sulfate dihydrate calcium content be more than 75wt%, attachment water content little
In 8wt%.
Described cement is 425 grades of Portland cements.
Described flyash adopt two grades of ashes and more than, fineness is not more than 25%, sulfur trioxide content be less than 3wt%.
The preparation method of sludge curing agent is as above：By after the feed components combined grinding of firming agent so that
Firming agent is in specific surface area is 450 ~ 650m2The powder of/kg.
The beneficial effects of the present invention is：
（1）The sludge curing agent of the present invention can reduce the moisture content of high-moisture percentage mud now, becomes silted up after can effectively reducing solidification
The internal strain of mud, prevents from ftractureing, and solidification intensity is high, hardening time is short, enables to coagulate soon, hard soon；
（2）The sludge curing agent of the present invention can heavy metal in active adsorption curing sludge, and with mud water content
Reduction, the heavy metal ion being originally free in water is cured, and reaches the requirement that landfill and building are banketed；
（3）The sludge curing agent of the present invention has carried out recycling to mud, solves the dirt caused by a large amount of siltations
The problems such as dye environment, energy-conserving and environment-protective, low engineering cost, profitable.
