Abstract
The invention discloses a building material prepared from sludge. The building material comprises the following substances in parts by weight: 15-26 parts of gravel, 10-29 parts of gypsum plaster, 5-10 parts of carclazyte, 3-11 parts of montmorillonite clay, 3-6 parts of calcium lignosulfonate, 1-3 parts of sodium methylsilanolate, 0.5-2.7 parts of calcium chloride, 1-7 parts of silica and 65-80 parts of sludge. The building material has the beneficial effects that the water content of the sludge is greater than 70%, the sludge is rich in combustion volatile substances such as organic matters, the volume reduction ratio and the weight loss ratio of the combusted municipal sludge are very high, the residues are stably solidified in a manufactured brick, no other chemical additive is needed, as the sludge is rich in combustible such as organic matters, the combustion heat of the combustible in the sludge can be sufficiently utilized in the brick blank combustion process, the raw material coal which is used for combusting the brick is reduced, and a novel way is provided for sludge treatment.
Description
Technical field
The present invention relates to a kind of material of construction utilizing mud to prepare.
Background technology
Municipal effluent is after the process of employing clean property sludge treatment method, excess sludge can be produced, this mud is except including organic matter, nitrogen, phosphorus, raising, generally all also include various heavy, also the concentration of many kinds is also had to exceed agricultural standards in these heavy metals, belong to hazardous and noxious substances, can not agricultural planting be placed in, the place that can affect human and livestock health can not be placed in.Treatment process at present for municipal sludge has multiple, generally has landfill, burning and comprehensive utilization.Although burying method processing cost is low, because sludge components is unstable, hazardous and noxious substances wherein and pathogenic micro-organism can contaminated land and water resourcess.The research direction utilizing mud to prepare material of construction to become new.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of material of construction utilizing mud to prepare.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Utilize a material of construction prepared by mud, comprise the material of following parts by weight: stone chippings 15-26 part, cream ash 10-29 part, carclazyte 5-10 part, montmorillonitic clay 3-11 part, wooden calcium 3-6 part, methyl silicon sodium alcoholate 1-3 part, calcium chloride 0.5-2.7 part, silica 1-7 part, mud 65-80 part.
Preferably, described a kind of material of construction utilizing mud to prepare, comprises the material of following parts by weight: stone chippings 20 parts, cream ash 2029 parts, carclazyte 8 parts, montmorillonitic clay 6 parts, wooden calcium 4 parts, methyl silicon sodium alcoholate 2 parts, calcium chloride 0.5-2.7 part, silica 1-7 part, 70 parts, mud.
Preferably, described mud is through the mud after the process of sludge treatment method.
The invention has the beneficial effects as follows: in material of construction of the present invention, moisture percentage in sewage sludge is rich in organic waits burning volatiles matter up to more than 70%, subtract that to hold reduction rate very large through the municipal sludge fired, remnant is stably fixed to be made in fragment of brick, do not need to increase other chemical additives, because mud is rich in organic grade for combustiblematerials, the combustion heat of the combustiblematerials in mud can be made full use of in adobe sintering procedure, reduce the feed coal of baking bricks, for sludge treatment provides new direction.
