Abstract
The present invention relates to a kind of restaurant garbage treating system and processing methods, the system includes kitchen garbage digestive system and biogas slurry treatment system, the kitchen garbage digestive system includes rubbish receiving hopper, bag-breaking machine, artificial separation platform, screw elevating conveyor, broken pulper, solid-liquid separating machine, hydrocyclone, damp and hot hydrolytic decomposition pot, Three-phase decanter centrifuge, homogeneous pond, anaerobic digestor, spiral dewaterer, biogas slurry terminal, solid refuse collection device, biogas purifier, refine purifying plant, CNG tank and methane boiler, kitchen garbage is obtained crude oil rouge by a series of processing by the present invention, biogas, biogas residue and biogas slurry, biogas residue, biogas slurry can be made into organic fertilizer, crude oil rouge prepares biodiesel after may be processed, not only substantially reduce the landfill land used in original kitchen garbage processing, effectively prevent the secondary dirt of environment Dye, also achieves the resource utilization of kitchen garbage, has applications well prospect.
Description
Technical field
The invention belongs to field of solid waste treatment, in particular to a kind of restaurant garbage treating system and processing method.
Background technique
For kitchen garbage the general name for being food and drink and rubbish from cooking, food garbage is the diet in restaurant, restaurant, unit dining room etc.
Residue and the process waste in rear kitchen, such as fruits and vegetables, meat, grease, millet cake；Rubbish from cooking is family daily life
Middle discarding biodegradable organic waste, such as fruits and vegetables, garbage material, leftovers leftovers, melon and fruit peel etc..
The characteristics of kitchen garbage is water content height, and moisture content reaches 80%-95%；Contents of saccharide is high, with protein, starch
Based on animal tallow etc., and salt content is high (part kitchen garbage capsicum, acetic acid content are high)；High organic content (albumen
Matter, cellulose, starch, grease etc.), impurity content is high, viscosity is high.It is perishable, easy to ferment, easy smelly, Yi Zisheng helminth, worm
The poisonous and harmful substances such as ovum and pathogenic microorganism and mould.
The kitchen garbage in China is mainly used for being collected by the peasant of surrounding city using there is long history
It directly uses as animal feed or is used as vegetable fertilizer, but the problem of this Land use systems is: in kitchen garbage
Containing a large amount of pathogenic microorganisms, zoogenetic infection is on the one hand easily caused, on the other hand causes human infection, forms cross-infection；
The rear easy infection of pig feed and the various diseases of induction, and then the dosage to sick pig is increased, therefore antibiotics can be increased
Residual, these left drugs enter human body by pork, are easy to cause damages to human health；Kitchen garbage makees feed may
It will lead to homologous contact scar；In addition, the grease in kitchen garbage is re-used as evil mind edible oil (trench after being refined by criminal
Oil) using also threat is generated to the health of the mankind, aflatoxins, the toxin such as benzene and some not clean generations of filtering are contained in gutter oil
Impurity, long-term consumption will cause the generation of chronic disease, or even can be carcinogenic.
With accelerating development for Urbanization in China, urban biomass garbage (comprising kitchen garbage, agriculture and forestry rubbish,
Animal wastes etc.) yield sharply increases, it has also become important pollution sources, it is anxious wait be pocessed and utilize, it develops and is suitble to China
The anaerobic digestion key technology and equipment of urban biomass garbage characteristic facilitate the technology body for improving municipal solid waste management
System improves municipal solid waste and handles intervention level.
Summary of the invention
A kind of restaurant garbage treating system and processing method proposed the purpose of the present invention is to solve background technique,
Kitchen garbage is obtained into crude oil rouge, biogas, biogas residue and biogas slurry, biogas residue, biogas slurry by a series of pre-treatments and Anaerobic Digestion
It can be made into organic fertilizer, crude oil rouge prepares biodiesel after may be processed, not only substantially reduce original kitchen garbage processing
In landfill land used, effectively prevent secondary environmental pollution, also achieve the resource utilization of kitchen garbage, have applications well
Prospect.
The kitchen garbage processing skill that anaerobic digestion process has been a mature and reliable, has had wide experience in developed country
Art has high-moisture, high grease, high protein, height although the kitchen garbage of China and the component of refuse of developed country slightly have difference
The characteristics such as salinity, but influence caused by these factors can be avoided by adjusting technique itself；So can be according to reality
