Abstract
The invention relates to a household waste treatment method. The household waste treatment method comprises the steps that waste is broken; the broken waste is dewatered; air classification is conducted on the dewatered waste, so that the waste is classified into large-weight substances, intermediate-weight substances, small-weight substances and dust; and the large-weight substances and the small-weight substances are placed in solutions for flotation respectively, so that different kinds of matter in the large-weight substances and the small-weight substances are further separated. According to the waste treatment method, the waste is classified in a more detailed mode, the waste hardest to treat is treated and utilized, and the problems of waste pollution and land occupation by the waste are solved.
Description
Technical field
The present invention relates to waste disposal method, particularly relate to one way of life waste disposal method.
Background technology
Rubbish comprises the resource of recoverable, also comprises the bad discarded object recycled and reused.
For the resource of recoverable, mostly by refuse classification, recycling.
For the rubbish of bad recycling, especially house refuse and medical waste, at present, adopts the way process of landfill or burning mostly.Landfill needs land occupation.In the big city of an inch of land is an inch of gold, a large amount of land occupation resource, loses more than gain.If landfill yard water seepage treatment is bad, also may polluted underground water source.Landfill also may produce biogas atmosphere pollution, causes adverse effect.
Waste incineration can produce the pernicious gases such as bioxin, and infringement human body is healthy, also has very large infringement to animal and plant.In order to solve the defect of above-mentioned process house refuse, China's No. 03150530.9 patent application proposes, and first by refuse breaking, then adopt selection by winnowing, rubbish is divided into organic matter, inorganic matter and plastics three major types by magnetic separation mode, then recycles respectively.Not necessarily as saidly in it after the method selection by winnowing rubbish can be divided into organic matter, inorganic matter and plastics three major types, then recycle respectively.Its flow process is complicated in addition, and required machinery equipment is more, and cost is also higher.
China's No. 200810228126.9 patent applications propose the processing method of one way of life rubbish.The method be by manual go-on-go after rubbish magnetic separator carry out magnetic separation, remaining organic matter sends into methane-generating pit fermentation, produces biogas, methane-generating pit dry carries out centrifugal dehydration, then sends into kiln dried after discharging, pulverize afterwards, with the particulate matter brickmaking after pulverizing.The method be also based on by after refuse classification, then process recycling respectively to sorted rubbish, the method is the same with No. 03150530.9 patent application, and cost is high, and flow process is complicated.
Summary of the invention
For the defect processing house refuse and medical waste at present, the object of this invention is to provide a kind of waste disposal method not accounting for land resource, low cost.
The embodiment of the present invention provides a kind of waste disposal method, and described method comprises:
By refuse breaking;
By the garbage dewatering after fragmentation;
Selection by winnowing is carried out to the rubbish after dehydration, described rubbish is divided into: be anharmonic ratio heavy substance, middle than heavy substance, Specific gravity material, dust;
Middlely respectively put into solution than heavy substance and Specific gravity material by described and carry out flotation, to be separated further by different material wherein.
Advantage of the present invention is that rubbish comes to naught by the present invention when land resource seized by modern society's garbage-surrounded city, refuse pollution, rubbish, solves the problem of refuse pollution, rubbish occupation of land; Resource in the most unmanageable rubbish fully reclaims, processes utilization by the present invention.Solve the problem that waste resources is recycled.
Detailed description of the invention
Embodiment
Chicken and duck bone, fishbone, throwaway chopsticks, cutlery box, dish leaf, polybag, napkin paper even small electric apparatus etc. is had, very bad classification in house refuse.That garbage disposal is the most thorny for non-classified rubbish.The present invention is directed to this kind of rubbish, devise a set of processing method, the method utilizes the means such as fragmentation, dehydration, selection by winnowing, flotation by above-mentioned house refuse, medical garbage sorting, to realize recycling.
The embodiment of the present invention provides a kind of waste disposal method, and described method comprises:
Step 1: by refuse breaking;
Step 2: by the garbage dewatering after fragmentation;
Step 3: selection by winnowing is carried out to the rubbish after dehydration, described rubbish is divided into: be anharmonic ratio heavy substance, middle than heavy substance, Specific gravity material, dust;
Step 4: middlely respectively put into solution than heavy substance and Specific gravity material by described and carry out flotation, to be separated further by different material wherein.
The embodiment of the present invention also comprise by described selection by winnowing out in carry out the step of milling respectively than heavy substance and Specific gravity material, as the alternative steps of step 4, or carry out with step S104 simultaneously.
By refuse breaking in step 1, be to make the Bottle & Can in rubbish broken, make the liquid that may exist wherein trickle out, and the rubbish wrapped in polybag is come out, the refuse breaking of bulk is become roughly uniform block.Can make all rubbish within the same processing time in thermal dehydration process subsequently like this, be dewatered to same degree.Refuse breaking can be adopted an impact crusher.Impact crusher can be broken by containers such as the vial in rubbish, plastic bottles, the liquid substance that may exist in container flowed out, so that processed, refuse breaking is become fritter simultaneously.Shredding refuse also can adopt one to smash machine and a pulper.Smashing machine main purpose is that the container such as vial, plastic bottle is broken, and the liquid substance that may exist in container is flowed out; Packaging bag, polybag can be cut and rubbish is wherein come out, and be blended by relatively large rubbish by pulper.Shredding refuse only can also adopt a pulper.
In step 2 by the garbage dewatering after fragmentation, refer to containing the material of moisture content in rubbish, as the liquid in dish leaf, bone, the food abandoned and some containers, at high temperature or under heated drying air, make it lose former water content.The degree of dehydration should reach 40% to 70%, and preferred degree of dehydration should reach about 70%.Degree of dehydration percentage to refer in rubbish removed moist part in certain matter water-containing total amount.Dehydration one can facilitate selection by winnowing subsequently, and two dewater can kill bacterium and virus.The environment that after dehydration, bacterium multiplies again is loss, therefore after sterilizing, bacterium not easily regenerates.
Dehydration can adopt various dewatering of the prior art, but preferably adopts heat treated way to make garbage dewatering.Such as can adopt a kind of or several arbitrarily combination in Electric heating, heated drying air mode of heating, waste heat of plant or waste heat mode, also can use drying tower.Wherein, Electric heating can comprise: a kind of or several arbitrarily combination in microwave heating, Resistant heating mode, lamp heated mode.Heat treatment is adopted to make the benefit of garbage dewatering be, while heated baking, also can make the thorough sterilization of rubbish.
