Technical field
The invention belongs to the waste resource environmental protection and utilize field, particularly relate to brick made of mud and method thereof that a kind of Environmental-protection comprehensive utilizes waste to fire.
Background technology
Produce a large amount of dredging silts in Jiang,Hu,He, extra large desilting process, the dredging silt regeneration needs processed, and processed is very difficult, and mud disposal options majority is to adopt stockyard to stack now, takies a large amount of farmlands contaminate environment.Produce the end slag of 22% left and right and the flying dust of 3-5% after burning city domestic garbage, wherein end slag can be processed into to gather materials and carry out the engineering application, flying dust is because being processed containing more heavy metal regeneration, at present, majority state adopts melting and solidification, cement solidification or chemical stabilization to the heavy metal in incineration of refuse flyash.Sewage plant sludge contains heavy metal because of it, and developed country has not been allowed for farm crop fertilizer, needs to process, and reduces the impact on environment.Environmental-protection comprehensive utilization to the waste resources such as slag, flying dust, mud at the bottom of dredging silt, consumer waste incineration has become difficult point and the focus that current castoff regenerative utilizes.
Chinese patent 02137159.8 discloses " a kind of brick made of mud " manufacture method, although the method has been utilized mud preferably, also has the following disadvantages, and the one, the method is added the solidifying agent of 15-35%, needs to consume other a large amount of resources, uneconomical; The 2nd, the toxicity leaching problem of heavy metal in sludge fails to solve; The 3rd, the mud water content is not clear and definite, directly affects the curing effect of goods.
Chinese patent 200380110486.4 discloses " being manufactured the method for goods by flying dust ", although the method can be removed the heavy metal in flying dust by sintering, also have the following disadvantages, the one, described method need be blended together flying dust and water, add water in flying dust, consumed water resources; The 2nd, easily produce flying dust in water ash mixing process and raise outward, contaminate environment; The 3rd, extrudate density is larger, and as Constracture unit, from great, structural load is heavy.
Chinese patent 200410014679.6 discloses " utilizing mud to manufacture the method for clay brick ", although raw material has been found in the production that the method is clay brick, but also have the following disadvantages, the one, add 10-20% dry powder and 5-10% powder ash in mud, the toxicity that can not solve heavy metal in sludge leaches problem; The 2nd, technique is numerous and diverse, needs machinery more, needs power more, and manufacturing cost is high; The 3rd, the clay brick folding strength deficiency of extrusion molding, be restricted range of application.
Chinese patent 200610040094.0 discloses " utilizing the method for pure sludge brickmaking ", although the method has been utilized the mud in Jiang,He,Hu, sea, the effect of reserved resource is arranged, but also have the following disadvantages, the one, the toxicity that the method can not solve heavy metal in sludge leaches problem; The 2nd, by sludge dewatering, water ratio reaches below 30% and is difficult to realize, operability is not strong.
Chinese patent 201010287142 discloses " utilizing domestic sludge, river and lake mud to fire the method for self-heat conserving energy-saving brick ", although the method has utilized municipal sludge and lake silt to make finished bricks, but also have the following disadvantages, the one, by mud, naturally stack to water ratio 50-60% stand-by, need take a large amount of places, the current silt stockyard of China has been a difficult problem, and uneconomical; The 2nd, because winter temperature is low, summer rainy water again, naturally reduce water ratio outdoor infeasible; The 3rd, to add the pore-forming material of fluxing of 3-8% in the brickmaking process, increased operation, and DeGrain, because mud itself can produce micropore through roast; The 4th, cast waste sand material source deficiency, and inevitably contain metallic particles and iron rust composition in cast waste sand, increased the deadweight of brick; The 5th, domestic sludge and riverway sludge have essence different, and the amount of sludge in Jiang,He,Hu, sea is much larger than the amount of domestic sludge, and the method lacks exploitativeness because failing the open measure that should take.
In sum, the subject matter that prior art exists has: the one, and sludge dewatering method operability is not strong; The 2nd, heavy metal during extruding brickmaking in mud is effectively solved, and the 3rd, riverway sludge and domestic sludge to be obscured, the intrinsic characteristics of mud and mud itself are underutilized.
How to overcome the deficiencies in the prior art, fully utilize multiple waste, become current waste resource environmental protection and utilized one of field crucial difficult problem urgently to be resolved hurrily.
