Description
Technical field
The invention belongs to environmental technology field, be specially a kind of sludge curing agent and manufacture method thereof that makes mud be used as renewable resource.
Background technology
Along with the development of national economy, environmental pollution is day by day serious, and compared in the past, people have more urgent demand to environmental improvement, but along with the diversification of industrial development, source of pollution are also more complicated.
In municipal effluent, just have and come from the various sewage that residential building, unit, school, hospital and communal facility drainage mechanism are collected.And mud is as the fittings of sewage disposal, the composition of mostly cannot filtering in sewage or clearing up all precipitates and concentrates in mud, the techniques such as that the treatment process of mud mainly comprises is concentrated, dehydration, digestion, fermentation, mummification, after processing by sanitary landfill, water body dissolve, the mode such as burning disposal, compost treatment and soil utilization make mud can minimizing, resource utilization.But some mud is because composition is too complicated, or in post-processed, sludge components structure is destroyed, and cause its become cannot be curing mud.For this mud, because it is in fluid state, cannot be existed easily with water body flow by appropriate disposal, make contaminated area extension; After muck surface is dry, dust can fly away into the medium harm of atmosphere, therefore need can make its method settling out in the short period of time, sludge solidifying agent is exactly one of product that object produces thus.
And sludge solidifying agent effect is in the market not satisfactory, solidification intensity is low, and can not be directly used in the mud that water content is higher, conventionally also need mud to do the processing that reduces water content, and complex procedures, cost is higher.
Summary of the invention
Technical purpose of the present invention is for the problem existing in reality, the sludge curing agent that a kind of cost is low, solidification effect is good is provided, can be directly used in solidifying of high-moisture mud, as the mud or the mud that produce from sewage work, industrial production, the mud producing from river course, lake etc., and be equally applicable to solidifying of grout.
For realizing above-mentioned technical purpose, technical scheme provided by the invention is:
A sludge curing agent, is characterized in that, comprises the component of following weight proportion:
The fluorite of 18～20 parts, the soda ash of 20～23 parts, the quartz sand of 7～9 parts, the gypsum of 40～50 parts, the unslaked lime of 10～12 parts, the Wingdale of 6～8 parts.
As preferably, described gypsum can adopt fluorgypsum.Fluorgypsum, mainly from using industrial solid waste, originates from the factories such as inorganic fluoride, organic fluoride factory and other hydrofluoric acid, and output is considerable, for belonging to the strong harmful solid waste of corrodibility, plant, animal and human is had to great side effect.Therefore use in a large number in the present invention, realize waste recycling, energy-conserving and environment-protective.
Further, by after contained component combined grinding, it is 300～600m that solidifying agent body is specific surface area
2/ kg's is Powdered, when mud is done to solidification treatment, easy to use, and solidification effect is good.
The present invention provides a kind of manufacture method of sludge curing agent simultaneously, can be used as the production of above-mentioned sludge curing agent, it is characterized in that, comprises the following steps:
(1) Fluorspar Powder of 18～20 mass parts is broken to the particle of particle diameter below 10mm;
(2) fluorite after pulverizing is mixed with the soda ash of 20～23 mass parts, the quartz sand of 7～9 mass parts, then by mixture grinding to particle diameter below 1mm;
(3) mixed powder after grinding is sent into calcining compartment calcining;
(4) fluorite, soda ash and quartz sand powder after the Wingdale of the unslaked lime of the gypsum of 40～50 mass parts, 10～12 mass parts, 6～8 mass parts and calcining are milled to predetermined pulverulence, mix.
Further, the calcining temperature of step (3) is controlled at 800～900 ℃.
Further, in step (4), by each component mixture grinding of solidifying agent to specific surface area 300～600m
2after/kg, can pack.
Beneficial effect of the present invention:
1) solidifying agent of the present invention is applied in the slurried materiales such as mud or cement, can realize fast solidifying, hard soon.When sclerosis, can also produce certain volumetric expansion, be conducive to improve the structure density of building product, strengthen grogs cohesiveness, therefore there is early strong, high-strength feature;
2) solidifying agent of the present invention passes through chemical reaction, from mud, absorb a large amount of free water contents and change into hydrated product crystal water, therefore under high water-solid ratio, can avoid the sedimentation phenomenon of particle before condensing, can directly solidify water content up to mud or the mud of 100%-300%, the intensity after solidifying and the volume of solidifying agent are proportional;
3) use solidifying agent of the present invention, it is little that hydration reaction is affected by organic matter, can cohere organic soil, to also having good solidification effect containing organic high cement slurry and mud;
4) solidifying agent of the present invention is powdered material, curing easy to use, at the construction field (site) solidifying agent is added in mud or mud and stirs and can realize fast setting in predetermined ratio;
5) curing mud or the mud of solidifying agent of the present invention both can harden in air, also can in water, harden, the mud or the sludge solidification body chemical resistance of concrete that reach some strength are good, even the dry wet immersion effect of seawater, cured body can not ftracture yet, and intensity does not decline yet.
