Abstract

The invention discloses a method for comprehensively recycling urban household garbage and sludge. The method comprises the following steps: manually sorting the household garbage; transferring the garbage into a bag breaking machine to carry out bag breaking treatment; screening the garbage subjected to bag breaking treatment through a drum; magnetically separating and crushing the screen underflow to obtain the crushed screen underflow; winnowing the substances in the screen in order to divide the winnowed substances into organic substances, inorganic substances and waste plastics; carrying out magnetic separation, manual sorting and crushing to the inorganic substances to obtain the materials to be used as the building materials; carrying out high-temperature cracking, crude oil recovery and crude oil refining to the waste plastics to obtain regenerated diesel oil; carrying out magnetic separation, manual sorting and crushing on the organic substances to obtain the crushed organic substances; mixing the crushed organic substances and the crushed screen underflow with the sludge to obtain a sludge mixture; and treating the sludge mixture by dewatering, drying and forming to obtain a finished product of carbon. The waste gas fuel produced during cracking the waste plastic at high temperature is used as the fuel for drying the sludge mixture, and the waste residue carbon blacks produced during cracking the waste plastic at high temperature is added to the sludge mixture to be used for preparing finished carbon products.

Description

The method of domestic waste and the comprehensive regeneration of mud
Technical field
The invention belongs to the treatment process of domestic waste, particularly a kind of method of domestic waste and the comprehensive regeneration of mud.
Background technology
Be living environment and the ecotope of to protect mankind, the processing of rubbish is more and more important, this year, and along with developing rapidly of economy, the raising of people's material and cultural life, larger variation is all occuring in domestic waste aspect quality and quantity two.Past rubbish is take food and organic waste as main, has also increased a large amount of stationery and waste or used plastics now, and wherein the rubbish of significant proportion can be recycled.Develop diversified technology of garbage disposal this year, comprised recycling, Landfill, incineration technology and composting technology.As:
Chinese patent application 03150530.9 discloses the one way of life garbage treating process, be divided into organism, inorganics and waste or used plastics after the broken selection by winnowing of domestic refuse process, magnetic separation, inorganics is used for making building materials, and the waste or used plastics cup is sent to waste plastics processing system, and organism is sent to fertilizer producing system.At present, the processing of waste or used plastics be mostly through Pintsch process for the preparation of diesel regenerated, waste or used plastics can produce waste residue carbon black, waste gas etc. in Pintsch process, these materials equally can be to environment.
Chinese patent application 200610122822.2 discloses a kind of municipal living refuse comprehensive treatment method, and thing in the sieve after the roller screen screening is used for fermentation, and screen underflow but can not well be processed, and is also to adopt landfill to the treatment process of such screen underflow at present.Technology of garbage disposal all exists one to process halfway problem in a word, causes the Re-pollution to environment.
In addition, at present most of sewage work in all parts of the country all can produce large batch of mud (the mud solid, semi-solid state and the liquid gurry that refer to dispose of sewage and produce herein every day; Contain certain organism, heavy metal and germ etc.), sludge treatment is mainly taked the method for landfill, fertilising and burning, and the water content high (65%-80%) due to mud contains again poisonous heavy metal, landfill disposal not only occupies a large amount of soils, and the severe contamination groundwater resource; As fertilizer sources uses, and also can cause secondary pollution, and the agricultural product security that causes because of fertilising and affect the HUMAN HEALTH event and happen occasionally becomes the very important factor that affects agriculture production, health of the masses and social stability.
Summary of the invention
For solving above technical problem, the object of the invention is to both provide a kind of domestic waste thoroughly can the processing, there is not Re-pollution, and can drives simultaneously the method for the synchronous conversion processing of municipal sludge.
The present invention seeks to realize like this:
A kind of method of domestic waste and the comprehensive regeneration of mud, it is characterized in that: domestic refuse is through artificial go-on-go, detect bulk stone, cloth, bamboo wood, glass, then rubbish is sent to bag-crusher and carried out the broken bag processing, rubbish after broken bag is processed sieves through cylinder, the screen underflow of screen underflow through magnetic separation, after being pulverized; In sieve, thing is divided into organism, inorganics and plastic waste through selection by winnowing, is used for making material of construction after the magnetic separation of described inorganics process, artificial go-on-go, pulverizing; Described plastic waste makes diesel regenerated through Pintsch process, recovery crude oil, refining; Organism after being pulverized after the magnetic separation of described organism process, artificial go-on-go, pulverizing, screen underflow and mud after organism after pulverizing, pulverizing are mixed to get mud mixture, described mud mixture is made the charcoal finished product through dehydration, oven dry, moulding, the waste gas fuel that produces in described Pintsch process plastic waste process is as the fuel of oven dry mud mixture, and the waste residue carbon black that produces during described Pintsch process plastic waste joins in the mixture of mud for the preparation of the charcoal finished product.
Adopt technique scheme, domestic garbage integrated class is processed, effectively utilize under the sieve after roller screen sieves Thing in sieve, organism prepares the charcoal finished product together with mud, the fuel value of made charcoal can reach the 3500-3800 kilocalorie.Simultaneously, the waste residue carbon black that produces in waste or used plastics Pintsch process process also for the preparation of charcoal, has been avoided the secondary pollution of waste residue carbon black.Meanwhile, the waste gas fuel that produces in cracking process is used for oven dry mud, makes waste gas fuel again be utilized, reach the purpose of saving the energy, also avoided the pollution of waste gas fuel to environment simultaneously, realized project zero release, the zero pollution.
In technique scheme, described mud be after sewage work dehydration water ratio less than 80% mud.
In technique scheme, the weight ratio of the organism after described pulverizing, the screen underflow after pulverizing and mud is to add organism after the 0.4-0.6 ton is pulverized and the screen underflow after pulverizing in mud per ton.
In technique scheme, described mud mixture first dewater to water-content less than 40% and then dry to water content be 10%-15%.
In technique scheme, be used for making non-burning brick after the magnetic separation of described inorganics process, artificial go-on-go, pulverizing.
Beneficial effect: the present invention is the domestic garbage integrated separating manipulation of regeneration, and driven simultaneously the regeneration of municipal sludge, avoided secondary pollution, realized the project zero release, zero polluted.
