Consumption building waste and sludge are connect, also, the sludge used can be high-moisture-contensludge sludge, without being dehydrated to sludge, at desiccation
Reason, energy consumption cost are low.
The embodiment of the present invention reacts to form gelling in preparation method using sa industrial solid wastes and alkali-activator
Material, and building waste is combined, have the strong cementation of similar hardening of cement, form solidified body by maintenance, using making
Grain, maintenance and it is dry obtain filtrate, can by sludge heavy metal and organic matter sealing in reactant, and have high cylinder pressure
Intensity.Industrial solid wastes and building waste materials are extensive, are not necessarily to high-temperature roasting, and there is no the big problem of carbon emission amount, greens
Environmental protection, realizes energy-saving, reduces cost.
The embodiment of the present invention kills the harmful microorganism in sludge, sa industrial solid by the strong basicity of alkali-activator
Waste generates [SiO after alkali-activated carbonatite4] tetrahedron and [AlO4] tetrahedral structural unit, pass through Si-O-Si and Al-O-Si
Link is configured to three-dimensional space network structure, is all to be attached to be formed with space by covalent bond between Si, O and Al atom
The ground polymers of tetrahedron rock-steady structure, heavy metal and organic matter in sludge etc. are existed with physically encapsulation and chemical bond form by sealing
In the space structure of ground polymers, the sa ingredient that building waste and sludge contain also alkali-activator effect under spot polymers
Reaction, in addition, the cementitious volcanic ash hydration reaction of class occurs under the action of water and hardens for the mortar in building waste, ground gathers
Object reaction jointly gets up the poisonous and harmful element sealing in sludge with volcanic ash hydration reaction, is formed simultaneously high-intensitive stabilization
Structure.
Common filtrate is the adsorptivities materials such as active carbon, quartz sand, gravel, zeolite and haydite in water treatment field at present
Material, active carbon service life is short, and the production processes such as zeolite are complex, and industrial cost is high.Also, current filter material surface compares
It is smooth, intensity is little, be prone to wear, therefore multiplicity of the filtrate used in bio-aeration biological tank to microorganism in existing water process
Property, microbial activity and microorganism colonization etc. are all unfavorable.
