Description
Technical field
The present invention relates to the method and system of a kind of food garbage, excrement, gutter oil and rubbish from cooking Combined Treatment, belong to
Field of domestic garbage treatment.
Background technique
According to source difference, kitchen garbage is broadly divided into food garbage and rubbish from cooking.The former is produced from restaurant, dining room etc.
The leftovers of catering trade, have the characteristics that yield big, quantity Relatively centralized, widespread, and the latter refers mainly to that resident is daily to cook
The leftover bits and pieces and leftovers discarded in tune, come from huge numbers of families, enormous amount but relative distribution, and overall yield is more than food and drink
Rubbish.Kitchen garbage is commonly called as hogwash, also known as swill, swill, is the sanitary waste that resident is formed during personal consumption, pole
It is perishable rotten, stench is distributed, is spread germs and viral.Kitchen garbage main component includes rice and flours food residues, vegetable
Dish, vegetable and animals oils, meat bone etc. have starch, cellulose, protein, lipid and inorganic salts chemically on composition.
Rubbish from cooking is with house refuse compared to compared with having the following characteristics that the content of organics such as 1) crude protein and crude fibre all
Height, perishable, stench；2) moisture content is high, is also easy to produce percolate, makes troubles to the collection transport and processing of rubbish；3) calorific value is low,
Limit the application of incineration technology.
The traditional main processing ways of rubbish from cooking are the modes such as burning and landfill, compost and anaerobic fermentation.It burns and fills out
The mode of burying is mainly that food waste is handled with domestic garbage mixing.Rubbish from cooking individually handles main by the way of biological treatment
For aerobic compost and producing methane through anaerobic fermentation.Since aerobic compost takes up a large area, stench is difficult to control and fertilizer market etc.
Problem limits a kind of popularization of the aerobic compost as extensive food waste (kitchen) rubbish mode.Anaerobic fermentation then becomes kitchen increasingly
The mainstream processing mode of remaining rubbish.
Gutter oil refers to all kinds of poor oils present in life, such as the frying oil of the edible oil, Reusability recycled.
Gutter oil the largest source is the oil separator of city large-scale restaurant sewer.
Summary of the invention
The object of the present invention is to provide a kind of method of food garbage, excrement, gutter oil and rubbish from cooking Combined Treatment and

Power plant；
In step 3), the biogas residue is burned after being dehydrated or resource utilization.
Above-mentioned method further includes steam heater when to separating grease in the gutter oil in step 1), for oil
Aqueous mixtures heating, separation product crude oil rouge, middle layer are the colloid of paste, bottom is oily waste water；
The oily waste water recycling is used for the broken slurrying of the food garbage and the rubbish from cooking.
Above-mentioned method, in step 3), the excrement send rubbish after rubbish and sundries sealing are packaged after being separated by solid-liquid separation or burns
Burn factory and office's reason；Excrement filtered fluid, which enters after conditioning tank, is separated excrement slag liquid dung by flocculation dewatering；Dewatered excrement slag send rubbish
Burning disposal；Supernatant enters incineration plant water process system by dedicated pipe network；
The dewatered sludge that the biogas residue obtained in step 2) and step 4) obtain carries out compost treatment.
The present invention also provides the systems of a kind of food garbage, excrement, gutter oil and rubbish from cooking Combined Treatment, it includes
Pretreatment system, anaerobic fermentation system, solid-liquid separation system, sewage disposal system and deodoration system；
The pretreatment system is for being crushed system after isolating inorganic sundries in food garbage, gutter oil and rubbish from cooking
Slurry, and separate fuel-displaced, organic solid content and concentrated water；
The anaerobic fermentation system is used to organic solid content and concentrated water carrying out anaerobic fermentation, generates biogas, and obtain
To biogas residue, biogas slurry and foul smell；
The solid-liquid separation system obtains rubbish and sundries and dirt for being separated by solid-liquid separation to excrement and the biogas residue
Water；
The sewage disposal system carries out purified treatment for the biogas slurry, the sewage；
The deodoration system is for handling the foul smell.
Above-mentioned system, the pretreatment system include splicing draining system, basket filter frame, broken pulping system and three
Phase-separation system；
The splicing draining system is used for the preliminary draining to the food garbage；The basket filter frame removes the meal
Organic solid content of partial size at least 8mm in drink rubbish, gutter oil and rubbish from cooking；The broken pulping system is used for the meal
Broken and slurrying is carried out after organic solid content of drink rubbish and rubbish from cooking removing partial size at least 8mm；
The three-phase separating system is used to separate fuel-displaced, organic solid content and concentrated water to the food garbage, to the basket
The gutter oil that formula filter frame removes organic solid content of partial size at least 8mm separates grease.
It further include steam heating when the three-phase separating system separates grease in the gutter oil in above-mentioned system
Device is heated for oil water mixture, three-phase separating system separation product crude oil rouge, the colloid that middle layer is paste, most
It is below oily waste water, the oily waste water is delivered to the broken pulping system.
In above-mentioned system, the system further includes flocculation basin, is used for the excrement through the solid-liquid separation system
Obtain the dehydration of the sewage, treated, and supernatant is further purified through the sewage disposal system.
In above-mentioned system, the system further includes compositing system, the natural pond for obtaining to the anaerobic fermentation system
The sludge that slag and the sewage disposal system obtain carries out compost treatment.
The invention has the following advantages that
The present invention is by food garbage, excrement, gutter oil and rubbish from cooking Combined Treatment；Operating cost is reduced, is saved manually,
