Abstract
The invention discloses a kind of sludge solidifying agent, it is characterised in that the sludge solidifying agent is mixed by two or three of component in polyacrylamide, anhydrous sodium sulfate, magnesia, calcium oxide；Wherein, the sludge solidifying agent is pressed：The weight proportion mixing of polyacrylamide 20% 80% and anhydrous sodium sulfate 20% 80%；Or, sludge solidifying agent is pressed：The weight proportion mixing of polyacrylamide 20% 50%, anhydrous sodium sulfate 30% 70% and magnesia 10% 20%；Or, sludge solidifying agent is pressed：The weight proportion mixing of polyacrylamide 20% 70%, anhydrous sodium sulfate 20% 60% and calcium oxide 10% 20%；Or, sludge solidifying agent is pressed：The weight proportion mixing of polyacrylamide 20% 70%, magnesia 20% 70% and calcium oxide 10%.The present invention is easy to use, does not return water after solidification sludge impermeable；It is with low cost, it is adapted to use in the large-scale sludge handling process for building base and sewage treatment plant of repairing the roads.
Description
Technical field
The present invention relates to environmental technology field, and in particular to a kind of sludge solidifying agent.
Background technology
When building subway, tunnel and mining area construction, shield machine can excavate the higher sludge of moisture content, its moisture content
Calcium, magnesium ion content are exceeded in 30%-60% or so, and sludge.At present, the sludge solidifying agent of in the market enters to this sludge
Effect is all undesirable during row solidification, and has that cost is too high, hardening time is short, be difficult to control to and pollute larger etc. ask
Topic.Therefore need a kind of cost badly controllable, prepare simple, solidification effect is good and sludge solidifying agent of environmental protection.
The content of the invention
For problems of the prior art, it is an object of the invention to provide one kind moisture content can be made high, calcium, magnesium from
The sludge of sub- content overproof realizes the sludge solidifying agent for not returning water after solidification, and solidification in a short time.
To achieve the above object, concrete technical scheme of the invention is：
A kind of sludge solidifying agent, the sludge solidifying agent is in polyacrylamide, anhydrous sodium sulfate, magnesia, calcium oxide
Two or three of component is mixed；Wherein,
The sludge solidifying agent is pressed：Polyacrylamide 20%-80% and anhydrous sodium sulfate 20%-80% weight proportion are mixed
Close；Or,
Sludge solidifying agent is pressed：Polyacrylamide 20%-50%, anhydrous sodium sulfate 30%-70% and magnesia 10%-20%
Weight proportion mixing；Or,
Sludge solidifying agent is pressed：Polyacrylamide 20%-70%, anhydrous sodium sulfate 20%-60% and calcium oxide 10%-20%
Weight proportion mixing；Or,
Sludge solidifying agent is pressed：Polyacrylamide 20%-70%, magnesia 20%-70% and calcium oxide 10% weight are matched somebody with somebody
Than mixing.
Further,
Technical scheme has the advantages that：Instant component is easily obtained, and it is easy to prepare, by each component
It is made by certain percentage by weight stirring, it is easy to use, water is not returned after solidification sludge impermeable；It is with low cost, it is adapted to big rule
Used in the sludge handling process for building base and sewage treatment plant of repairing the roads of mould, 50% soil and 50% water system can also be will be equivalent to
Into mixing mud weight one thousandth to 5/1000ths sludge solidifying agent add mixing mud in be used for block coal seam
Mining area goaf, can both ensure the mobility at initial stage, can fill up goaf solidify afterwards completely again, oxygen is added in the application
When changing magnesium and calcium oxide, the also effect with improved soil, with very strong practicality.
