Description
Technical field
The present invention relates to a kind of curing agent, especially a kind of sludge treatment curing agent and preparation method thereof.
Background technology
With the rapid development of economic construction, mankind's activity migration is frequent, and urbanization process is accelerated, and quantity of wastewater effluent is substantially
Increase, large amount of sewage direct emission lake, then rainfall Surface Runoff, production sand and production dirt is added to lead to China some areas river, lake
Pool muddy water environmental aspect drastically deteriorate, many rivers, lake siltation face raise, siltation it is extremely serious so that mud siltation increasingly at
For social public hazards, cause a series of environment hidden danger.Therefore it is badly in need of developing a kind of sludge treatment curing agent and its system
Preparation Method.
Invention content
A kind of simple for process, at low cost, effect is provided the purpose of the present invention is to solve above-mentioned the deficiencies in the prior art
A kind of high sludge treatment curing agent and preparation method thereof of rate.
To achieve the goals above, a kind of sludge treatment curing agent designed by the present invention includes 20-30 by weight
Part swollen resin, 15-20 parts of cement, 5-10 parts of diatomite, 10-15 parts of quick limes, 6-8 parts of sodium metasilicate, 8-10 parts of polyacrylamides
Amine, 5-10 part polyvinyl alcohol, 2-5 parts of tannic acids, 5-8 parts of neopelexes, 20-30 parts of fillers, the filler is by weight
It includes 40-50 parts of sepiolites, 10-30 parts of bentonites, 5-10 parts of rare earths, 20-30 parts of kaolin to measure part.
A kind of preparation method of sludge treatment curing agent, first by 40-50 parts of sepiolites, 10-30 parts of bentonites, 5-10
Part rare earth, 20-30 parts of kaolin are mixed, and are then ground to powder, and filler is made, spare；Then 20-30 parts of expansions are set
Fat, 15-20 part cement, 5-10 parts of diatomite, 10-15 parts of quick limes, 6-8 parts of sodium metasilicate, 5-8 parts of neopelexes,
20-30 parts of fillers stir evenly, and are then placed in heating furnace and are heated, and temperature is 230-250 DEG C, heating time 2h, cooling
It is mixed with 8-10 parts of polyacrylamides, 5-10 parts of polyvinyl alcohol, 2-5 parts of tannic acids after to room temperature, and is ground into
The powdery that grain size is 5-15 μm is to get sludge treatment curing agent.
The adsorbable poisonous and hazardous substance of swollen resin in the present invention converts it into similar soil or cementing strength very
Big solid accelerates the process of sludge dewatering, while swollen resin can adsorb and cure silt to reduce the water imbibition of sludge
Heavy metal in mud, and with the reduction of mud water content, the heavy metal ion dissociated in water originally is cured, reaches and fill out
Bury and build the requirement banketed.Main component in cement and quick lime generates the crystallization water by hydration reaction society and absorbs part water
Point；For absorbing water, polyacrylamide and polyvinyl alcohol are used to absorb the large quantity of moisture in mud, and rapid for diatomite and sodium metasilicate
It flocculates and pellet, fine grained is made to be roughened, improve infiltration coefficient and dewatering speed；Tannic acid and neopelex conduct
Auxiliary agent plays the role of anti-oxidant and dispersion.
Sepiolite, bentonite, kaolin in filler can regard the carrier of above-mentioned active ingredient, and rare earth is then used to promote
Active ingredient plays a role, and plays catalyst.
A kind of sludge treatment curing agent that the present invention obtains, can reduce the moisture content of high-moisture percentage mud, Neng Gouyou
Effect reduces the internal strain of mud after solidification, prevents from cracking, and solidification intensity is high, and hardening time is short, can realize fast solidifying, fast
Firmly, the problems such as pollution environment caused by a large amount of siltations, energy conservation and environmental protection are solved.
