Embodiment 1

[0058] Embodiment 1 A kind of method of utilizing urban and rural domestic garbage and sludge to prepare industrial foaming filler

[0059] A method for preparing industrial foam filler by utilizing urban and rural household garbage and sludge, said method comprising the following preparation steps:

[0060] Step (1): Dispose of domestic waste:

[0061] ①Material sorting: Disassemble the material and remove non-domestic waste;

[0062] ②Material cracking: tearing, cutting, and crushing the sorted materials to crack all kinds of materials in domestic waste;

[0063] ③Material analysis: add the decomposed urban and rural domestic waste to the solid waste pollutant treatment system, the system temperature is 800°C, decompose the compounds in the domestic waste, analyze, crack, condense and carbonize the organic matter, and obtain material 1;

Abstract

The invention discloses a method for preparing industrial foaming filler with urban and rural household refuse and sludge. The method mainly includes the steps that household refuse and sludge with non-organic matter as the main component are subjected to resolving treatment, and residues serve as aggregate for preparing the industrial foaming filler; sludge with organic matter as the main component is subjected to hydrolysis treatment, and hydrolyzate serves as a foamer base material; the foamer base material, a foam booster and an additive are used for preparing a composite foamer; the aggregate obtained by treating the household refuse or the non-organic sludge, the composite foamer and cement are mixed and homogenized, water is added, stirring is performed, foaming machine filling is performed, and then the industrial foaming filler is obtained. The filler is small in thermal conductivity and water absorptivity, free of mildewing, resistant to chemical corrosion, stable in performance, fireproof, nonflammable, safe and reliable, and can be applied to freeze protection, heat preservation, heat insulation, shock absorption, noise reduction, housing construction, decoration engineering and roads, sponge cities and wetland construction.

Description

technical field [0001] The invention relates to the harmless treatment and resource utilization technology of solid pollutants, in particular to a method for preparing industrial foaming fillers by using urban and rural household garbage and sludge. Background technique [0002] Urban and rural domestic garbage and sludge have caused great harm: organic matter rots, compounds decompose, emit ammonia, hydrogen sulfide, odor and other toxic and harmful gases, pollute the atmosphere; viruses, bacteria, insect eggs, etc. reproduce, breed, and spread; pollution The pollutants seep into the ground along with the sewage, flow into the river, pollute the land and the groundwater system; decompose or ionize the metal and its compounds, pollute the water body and the land. [0003] At home and abroad, a lot of research and experiments have been carried out on the treatment and utilization of urban and rural domestic waste and sludge, including stacking after reduction or drying, landf...
