Abstract
The invention provides a comprehensive treatment method for urban garbage and sludge. The comprehensive treatment method is characterized by comprising the following steps of (1) constructing a comprehensive garbage and sludge treatment plant; (2) classifying garbage; (3) treating the garbage; and (4) using the treated garbage. Biogas produced by using the comprehensive harmless treatment method for urban garbage and sludge, provided by the invention, can be used as a combustion improver for incinerating garbage and sludge, the combustion stability can be improved, the generating efficiency of an incinerator can be increased, and the whole yield can be increased; the produced biogas is used as the combustion improver, so that the incineration efficiency of domestic garbage and dried sludge is increased, and the incinerated slag is used for producing building materials; and the operating cost of a garbage recycling vehicle is relatively high all the time, kitchen waste is converted into biomass diesel through oil treatment, and then, the biomass diesel is used by a garbage transportation vehicle, so that the using cost of the vehicle is reduced.
Description
Technical field
The present invention relates to technical field of waste treatment, specifically a kind of municipal refuse Method for comprehensive treatment of sludge.
Background technology
At present, the whole world produces 4.9 hundred million tons of rubbish every year, and only China just produces nearly 1.5 hundred million tons of municipal refuses every year.Current Municipal Solid Waste in China accumulation volume of cargo in storage has reached 7,000,000,000 tons.According to State Environmental Protection Administration's prediction, China's municipal refuse annual production in 2010 will be 1.52 hundred million tons, within 2015, will reach 2.1 hundred million tons with the year two thousand twenty.The end of the year in 2009, national urban wastewater treatment amount reaches 280 billion cubic meters, and wet mud (moisture content 80%) generation breaks through 2,000 ten thousand tons.
Domestic waste to refer in city dweller's daily life or provides the solid waste produced in the activity of service for city daily life, is one of chief component of solid waste.Its composition mainly comprises kitchen excess, waste paper, waste plastics, useless fabric, old metal, cullet potsherd, ight soil, waste and old furniture etc.The current garbage disposal of China mainly adopts landfill and burning electricity generation two kinds of patterns.At present, garbage disposal relatively lags behind, and the ratio of landfill disposal is more than 85%, and waste incineration and generating electricity can greatly reduce landfill and can save a large amount of land resource in fact, decreases the atmosphere pollution of landfill to underground water and landfill yard surrounding enviroment simultaneously.According to China's present policies, municipal solid wastes incineration power generation technology will be taken as the leading factor with mechanical kiln grate furnace, be aided with coal-garbage multifuel combustion fluidized bed garbage combustion technology and other technologies.
The mud that wastewater treatment in China factory produces, has 80% not dealt carefully with, and mud is arbitrarily stacked and the pollution that causes highlights with pollution problem again, and causes the concern of society.On the one hand, the technology path of China's specific resistance to filtration it be unclear that; On the other hand, China does not set up the policy system of specific resistance to filtration yet, problem left over by history makes mud predicament more and more serious, today that, water environment day by day serious at water pollutions worsens increasingly, the sewage disposal system lacking mud safe disposal consideration is incomplete, also cannot meet environmental goals requirement, the secondary pollution problem day that mud causes is aobvious outstanding.
Summary of the invention
For making up prior art deficiency, the present invention aims to provide a kind of municipal refuse Method for comprehensive treatment of sludge.
For realizing above object, the present invention by the following technical solutions,
A kind of municipal refuse mud integrated treatment detoxification method, at least comprises the following steps flow process:
Step one: garbage sludge integrated treatment factory builds; Step 2: refuse classification; Step 3: garbage disposal; Step 4: the rubbish after process uses.
In step one: build garbage sludge integrated treatment factory, and rubbish honesty produced and mud are transported in the garbage sludge integrated treatment factory of construction.
In step 2: the rubbish in city and mud are classified, be mainly divided into daily life rubbish, dewatered sludge and changing food waste.
In step 3: rubbish step 2 having been divided class, the trench wet goods wherein in changing food waste is collected a rubbish part and is used as biodiesel supply vehicle and urban construction machinery through grease process; Another amount of grease is used as urban afforestation by the organic fertilizer produced after mix rear Anaerobic Treatment with the mud of dehydration according to 1:2; The daily life rubbish of dewatered sludge after sludge drying with dehydration of another part uses as power plant burning fuel, and then the electric energy produced is city people's life production and application; In addition dregs of incinerator uses as the construction material of urban construction.
The invention has the beneficial effects as follows: the biogas produced through municipal refuse mud integrated treatment detoxification method of the present invention, can be used as the combustion adjuvant of rubbish and sludge incineration, improve flameholding, promote incinerator generating efficiency, increase integral benefit; The biogas produced is as combustion adjuvant, and promote the burning of daily life rubbish and dewatered sludge, the slag after burning is produced into construction material; Garbage reclamation car operation expense is always higher, by changing food waste (comprising waste oil) grease process, is converted into biodiesel, for garbage transporting vehicle, decreases vehicle use cost.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Consult Fig. 1, in the embodiment of the present invention, a kind of municipal refuse Method for comprehensive treatment of sludge, at least comprises the following steps flow process:
Step one: garbage sludge integrated treatment factory builds; Step 2: refuse classification; Step 3: garbage disposal; Step 4: the rubbish after process uses.
Wherein in step one: build garbage sludge integrated treatment factory, and rubbish society produced and mud are transported in the garbage sludge integrated treatment factory of construction.
In step 2: the rubbish in city and mud are classified, be mainly divided into daily life rubbish, dewatered sludge and changing food waste.
In step 3: rubbish step 2 having been divided class, the trench wet goods wherein in changing food waste collects a part for rubbish, uses as biodiesel supply vehicle and urban construction machinery through grease process; Another amount of grease is used as urban afforestation by the organic fertilizer produced after mix rear Anaerobic Treatment with the mud of dehydration according to 1:2; The daily life rubbish of dewatered sludge after sludge drying with dehydration of another part uses as power plant burning fuel, and then the electric energy produced is city people's life production and application; In addition dregs of incinerator uses as the construction material of urban construction.
