Abstract
The garbage is first treated aerobically and anaerobically in treating pool to sterilize, disinfect and deodorize and biologically degrade and convert organic matter into fuel gas as side product, which is then screened and separated to produce solid fuel, coal saving additive, inorganic matter, building material and liquid fuel, paint and adhesive. The method eliminates the pollution of garbage, makes full use of the garbage, changes waste into valuable, and has the advantages of investment saving, high benefit, pollution prevention, energy conservation and the like. Is suitable for harmless treatment and utilization of household garbage and partial industrial garbage.
Description
The present invention relates to the harmless treatment of the processing of solid waste, particularly rubbish and utilize method.
At present, the processing to domestic waste generally is the employing compost, burns, buries even be poured among the rivers,lakes and seas that these methods not can solve the pollution of environment in the world.As, to bury and with the method for toppling over a large amount of biological bacteriums is drifted about in the water or mix in the underground water, the severe contamination water source has enlarged pollution range artificially, causes even more serious secondary pollution; Compost treatment is not only taken up an area of wide, and the obnoxious flavour that produced in the septic process of heap fermentation of rubbish can polluted air, the sewage polluted-water in the water that permeates the ground; It is limited to burn handled component of refuse, and wastes combustible material, and flue dust has a large amount of 3.4-benzopyrene pollution atmosphere.Prior art is to the processing of solid waste, generally be adopt respectively that methods such as chemistry, physics, biological and magnetic sort, screen, pulverize, the difficulty of burning, pressing treatment, refuse treatment engineering is big, investment is big, income is few, wherein majority only is in order to dwindle the volume of rubbish, shift or change blowdown mode, product after the only useful refuse treatment is done material of construction or thermal utilization, and rubbish is not carried out comprehensive harmless treatment and comprehensive utilization.
The objective of the invention is to overcome the shortcoming of prior art, a kind of harmless treatment of rubbish is provided and utilizes technology, domestic waste is carried out harmless treatment, eliminate the secondary pollution of rubbish, turn waste into wealth, all comprehensive utilizations, save energy again when curbing environmental pollution makes rubbish become fuel and fuel dope and material of construction.
The present invention is achieved in that at first rubbish to be poured into and carries out aerobic treatment and anaerobic treatment in the treating pond, add chemical reagent, with biochemical method (accounting for more than 70% of rubbish total amount) used in the burning that the organic matter degradation in the rubbish changes into solid fuel and inflammable gas.After carrying out harmless treatment three days make rubbish slag drying, water content 5-10% by high temperature.Again exsiccant rubbish is transported in the multilayer sifting machine with e Foerderanlage from treating pond and screens, sub-elect plastic waste, aphlogistic inorganics and organic matter rubbish slags such as the brick and tile that granularity is big, pottery, glass with hydrometer method and granularity method.Carry out processing and utilization then respectively: will be in the organic matter rubbish slag add the organism (as rice husk, wheat straw, wood chip etc.) after pulverizing and the ignition dope (as SODIUMNITRATE, saltpetre, magnesium etc.) that burns, make coal-saving additive after, mix and burn in the raw coal; Sand, lime stone, slag ash and brick and tile through after the grinding and processing, are added lime powder and terra alba and make slag ashes cement; With brick and tile, pottery, ash, sand add cement through after the grinding and processing, the cement solidifies agent and water, be pressed into brick on the unburned coal ash sand after stirring evenly again; Broken cullet, pottery are added the unsaturated polyester resin tackiness agent and auxiliary material is made finishing material,, plastic waste handled through chemical industry make liquid fuel, paint, tackiness agent as artificial marble.
The invention provides a kind of harmless treatment of rubbish and utilize method, eliminated the secondary pollution of rubbish, all comprehensive utilization is turned waste into wealth, and when curbing environmental pollution, makes rubbish become fuel and fuel dope and material of construction.The moisture content that just carries out in screening and separating, the rubbish after rubbish process aerobic treatment and the anaerobic treatment has reduced about 90%, the weight saving of rubbish, volume-diminished, 70% is fuel, reduced the screening and separating kind, screening and separating, the volume that can reduce screening installation and power are reduced investment outlay easily, high efficiency, harmless to environment and operator simultaneously.The coal-saving additive of making mixes when burning in the raw coal according to the ratio of 30-60%, and through simultaneous test, its thermo-efficiency meets or exceeds equal raw coal, and obnoxious flavoures such as sulfurous gas reduce 50-70%, and smoke discharge amount reduces 30%, saves raw coal 20-40%.Be applicable to the harmless treatment of domestic refuse and organic industry rubbish and the processing and utilizing of utilization and inorganic industrial waste.
The present invention further describes below with reference to embodiment:
