Description
Technical field
The present invention relates to waste disposal method and treatment facility technical field, especially a kind of domestic organic food waste disposal method and treatment facility.
Background technology
Domestic organic food rubbish mainly comes from: letter sorting or put on by classification rubbish and straw class packing materials such as meat that vegetables, fruit, shell and the anorexia of generation use, egg, fish in that the market of farm produce directly produces or the domestic waste; " swill " and tankage that dining room, restaurant etc. produce; The green grass that afforestation produces, fallen leaves, branch etc.Ways such as landfill, burning are adopted in domestic organic food refuse treatment at present more, environment are produced immeasurable influence and loss.The organic waste that one 1,300,000,000 big country produces every day affects people's life constantly, and various ways such as garbage loading embeading burning all can't satisfy the paces that China develops to urbanization fast for city sizeization, the integrated construction in rural cities and towns.How to solve the changing food waste, the organic waste that produce in the quick urbanization development of China? organic waste can be turned waste into wealth? compared to adopting treatment processs such as landfill, burning, organic fertilizer is made in domestic organic food rubbish microbiological deterioration fermentation, and handling domestic organic food rubbish by this way is better choice.With the general mode that adopts bar buttress compost or storage compost of domestic organic food rubbish microbiological deterioration fermentation.Its technological process is: domestic organic food rubbish send destructor plant to concentrate to carry out heap fermentation, in the compost or use the anaerobism microbial inoculum, or the method for not adding microbial inoculum spontaneous fermentation.But this processing mode needs that domestic organic food rubbish is focused on destructor plant to focus on, changing food waste, organic waste rot easily owing to it, can produce a lot of waste liquids generations of stench and transportation, environment is produced a large amount of pollutions, how solve that organic waste rots, the stench problem from the source? how from the source domestic organic food rubbish being handled is the hang-up of our appearance of the city environmental sanitation of puzzling.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of domestic organic food waste disposal method and treatment facility are provided, pollutent is controlled from the source, the transportation cost of rubbish and the expense that landfill burns have not only been reduced, and the peculiar smell that has reduced the organic waste fermenting process produce and controlled waste liquid in the rubbish transportation throwing, emit, drip, leak, solve domestic organic food rubbish and rotted easily, can produce malodorous technical problem, further improved environmental quality.
The technical solution adopted for the present invention to solve the technical problems is: a kind of domestic organic food waste disposal method comprises the steps:
A. domestic organic food rubbish carries out solid-liquid separation on the spot: at first by the dehydration platform domestic organic food rubbish is carried out processed, the solid waste of dehydration back gained is pulverized on the spot by pulverizer, and the waste liquid of dehydration back gained enters the effluent purifying groove;
B. solid waste disposal: will pulverize in the solid waste input fermentation machine of back gained and add more than one mushroom microorganisms, regulate the water content of solid waste, solid waste is under 55%～65% condition in humidity, carried out deodorizing, fermentation, decomposition totally 120～150 hours, get biological organic elementary fertilizer, the organic elementary fertilizer of biology is concentrated with the mode of bar buttress compost or storage compost again and carried out Secondary Fermentation, get organic fertilizer;
C. liquid waste disposal: add more than one microorganisms in the waste liquid of dehydration back gained, carry out the oil removing purifying treatment, the waste liquid after the processing changes into foliar nutrient or enters sewer line.
The mushroom microorganism of adding in the solid waste disposal particularly, is actinomycetes, thread fungus, yeast, Bazillus bacterium.The microorganism of adding in the liquid waste disposal is actinomycetes, bacillus, Bacillus natto, capsule bacterium, smooth daughter bacteria.
Particularly, the mushroom microorganism of adding in the solid waste disposal is fermentation pichia yeast (Pichiafermentens), and the microorganism of adding in the liquid waste disposal is viride (Trichoderma viride), subtilis (Bacillus subtilis), bacstearothermophilus (Bacillusstearothermophilus), thermomonospora fusca (Thermomonospora fusca), lactobacterium casei (Lactobacillus casei).
A kind of domestic organic food refuse treatment plant that adopts described domestic organic food waste disposal method to handle domestic organic food rubbish, comprise domestic organic food rubbish is carried out the dehydration platform of processed, pulverizer, the effluent purifying groove of placing waste liquid that solid waste is pulverized on the spot, places the fermentation machine of solid waste fermentation, described pulverizer is positioned at the below of dehydration platform, the solid waste discharge port of dehydration platform is connected with the opening for feed of pulverizer, and the waste liquid discharge port of dehydration platform is connected with the import of effluent purifying groove.
Further, described pulverizer is a beater disintegrating machine.
Further, be connected with the microbial strains proportioning machine that drops into microbial strains according to fermentation machine stirring condition automatically above the described fermentation machine.
The invention has the beneficial effects as follows: the domestic organic food refuse treatment plant is placed in rubbish such as hotel, restaurant, hospital and scene, sub-district and produces ground, timing or not timing ground are put into domestic organic food rubbish wherein and are handled, organic waste is handled before not rotting, become biological organic elementary fertilizer, this process reduces the waste flow swivel link, carries out domestic organic food garbage harmless on-the-spot disposal.Pollutent is controlled from the source, the transportation cost of rubbish and the expense that landfill burns have not only been reduced, and the peculiar smell that has reduced the organic waste fermenting process produce and controlled waste liquid in the rubbish transportation throwing, emit, drip, leak, solve domestic organic food rubbish and rotted easily, can produce malodorous technical problem, further improved environmental quality.
