Abstract
An aqueous solvent method for sterilizing and classifying life garbage in urban area features that the substances whose specific weight is less than that of water, such as film, plastics, bamboo, wood, etc., can be firstly separated and reclaimed, or fully burnt, the organic substances semi-suspended in water can be neutralized and drained, or fermented to become organic fertilizer, and the deposit can be separated to remove metal, and neutralized and pulverized to become building material.
Description
The present invention utilizes common natural water or tap water to make diluting solvent, under the sterilization situation all kinds of differences of domestic waste is constituted things, the proportion in the water dilution, and the difference that character presents gives progressively sorting and comes, more specially to recycling.
Use this method, not only can accomplish non-secondary pollution, the processing environment standardization, and the energy continuous operations, operation easier is low, and province is doubly a lot of relatively for high heat generating of output investment ratio or heat energy utilization, owing to have utility value, its processing cost is comparatively economical, even can accomplish meagre profit production.It is a kind of selection way of low developed area ideal.
Development along with society, improvement for self and descendants's living environment, urgent need is carried out environment protection standard to domestic waste, the processing of non-secondary pollution, advanced country's high temperature generating system can way be ripe, successful illustration, but its investment is huge, and the technical equipment complexity allows low developed area Wang Er step back.
And direct sorting, burning, the simple process of shortage scientific knowledge, not only can not reach the purpose (can not continuous operations) of sorting, and just can't solve secondary pollution at all, low temperature burns and not only produces a large amount of harmful smog, and wherein can grow carcinogenss such as toxin, germ such as Er Evil that human body had fatal risk etc. on the contrary, loss is dropped in various places for this reason should be in ten million yuan.Should not learn the lesson?
Can both non-secondary pollution be arranged, investment relatively economizes, suit the way of owing site of an exhibition district environmental protection treatment? answer should be sure.
Because the maturation of chemical industry, by the chemical industry way, avoiding low temperature burns, with middle " solvent " dilution sorting is fully feasible, according to material benefit, the principle of reality, common natural water or tap water are exactly optimal standard solvent, in using water as dissolving agent process, add a certain amount of strong acid, highly basic, remove the life condition of bacterium, decompose itself, and can be as returning the Nature and add its fertility as fertilizer, not only can solve the source of secondary pollution, and be the dilution of solvent with water, the buoyancy of formation is with all kinds of proportion differences, the mishmash branch of different in kind comes, letter sorting again, neutralization, clean, specially, has certain economic value to recycling.The rotten thing of the mashed dish of biology based on carbohydrate, after the neutralization, by doing fermentation or wetting to ferment and make fertilizer, be anti-unwanted bacteria regeneration, preferably adopt the chemical acid alkali neutralisation to produce the Nitrogen, Phosphorus and Potassium of certain standard, return, and suitable economic worth is arranged in nature, its fertility is except that nitrogen own, phosphorus, potassium, and the advantage that bacterial manure is still arranged is that general chemistry is fertile incomparable.
Present method detailed process is:
One, adjusts solvent ratios, carry out sterilization and prepare
1, according to the domestic waste input amount, calculate to drop into the amount of solvent, and note keeping certain depth, separate in order to all kinds of buoyancy, the different rubbish thing of proportion, being generally and dropping into solid objects is 1T, water solvent is 3～5T, the degree of depth with more than the 3m for suitable.
2, in solvent, add 3%～5% sterilant, make sterilization, sterilization usefulness as strong acid, aqueous alkali etc., also, next step gets ready for reclaiming composting, because solubleness can not be excessive in water for strong acid or highly basic, as if 3%～5% this amount comparatively suitable, its pH value alkali is 9～10, and acid is 3～4 for suitable.
Two, feed intake and whisk sorting
The solid domestic waste is dropped in the prepared solvent, stir first stirred for several minute, allow all kinds of refuses separate with improved rotation.
1, because wood chip, bamboo piece, film, vacuolar membrane, woven bag, plastics proportion less than water, can be bubbled through the water column, uses earlier dedicated separation machinery, send second special use branch pond again to, be for further processing, still available natural water of solvent or tap water clean, but adding of germicide does not clean to suitable with neutralization.
2, in stirring, mashed vegetables are rotted biological, and proportion is bigger slightly than water, and for body is arranged, generally can become half floating shape in water, with special machinery it are sent into special-purpose scavenger.
3, metal, dirt, glass, stone, material that the battery geometric ratio is great sink at the bottom of the pond, send into the treating pond sorting with special machinery.
Three, recycle
1, with wood chip, wooden unit, film, plastics, vacuolar membrane, woven bag etc. in special-purpose pond with the little water solvent neutralize again clean after, with the sticking power difference of special machinery according to film, plastics, vacuolar membrane, woven bag, further separate again, the wood that can not separate fully, bamboo, plastics, vacuolar membrane, can be with heating up simultaneously, at 100～500 ℃ plastics, film are all dissolved, isolate wood, bamboo; Because film, plastics, vacuolar membrane, woven bag have polyvinyl chloride, polyethylene, polypropylene benzene compound composition should add catalysis, neutralizing agent in dissolving, the material that makes assorted essences such as chlorine wherein be converted into not tool pollution and have, as add an amount of soda ash, chlorine is converted into salt.Treated paint, coating and the recovery plastics usefulness done of solvent has certain economic value.
2, mashed dishes a large amount of in the suspended substance and corresponding organism are sieved, pulverize under sterilization and add corresponding corrective such as ammonia, a little sulfuric acid (sulfur waste acid, hydrochloric acid all can), transferring PH is 6～7, as fertilizer.Calculate through theory, general solid is nitrogenous 5%, phosphorus 2%, and few potassium, but can directly make compost, farm manure usefulness, and as adding bacterium compost or fermentation earlier, add according to ternary is fertile again, will form the organic multiple bacterial manure of the ternary that is better than carbon ammonia, have certain economic and be worth.
3, after metal, battery and dirt, glass, stone water clean neutralization, sorting again, silt can be used for harmless soil, even material of construction, metal directly reclaim, battery is told and collected a certain amount ofly, remake specially to processing, it should be noted that glass and stone here, can influence silt separates, with behind the magnetic separation metal, it is suitable answering crushing screening, makes building materials after the cleaning or topples over as silt.Its metal recovery is worth higher, and silt is worth lower.
Four, the recycling of water
Because domestic refuse will draw a part of water, after surplus water is collected, add and will replenish a part after the agent of wadding a quilt with cotton is with fixed attention handled and re-use, way is the same.Settling after the flocculation, the filtration back mixes with organic mashed dish, rotten thing etc. and makes fertilizer, and as independent collection, according to detecting data after the wastewater treatment, after the drying, its nitrogen, phosphorus, potassium content are higher than 15%, and fertility is better than carbon amine greatly.Be flowers and plants, fruit tree ideal organic fungi-manure (preferably without the hydrochloric acid neutralization, because the chlorine root in the fertilizer is unfavorable to tobacco, flowers and trees, fruit tree).
Example one:
The 5T domestic waste is poured into long 4m, wide 2.5m, dark 4m, water solvent 25m
3The first main mixing pit in, with overturning or Mixing Machine, stir 5 fens kinds, supernatant wood, bamboo, plastics, film, woven bag are changed in the special-purpose attached pond with separation machinery, add 5% ammonia in water solvent, PH is 9～10, and bacterium can not survive, and in and the rubbish middle acid substance, and the rancid smell that produces.Be environment purification, the special-purpose alkali of Working environment gas suction pond can be purified.Use valve and discharging to enter the half mashed dish that suspends etc. and filtered attached pond, crushing screening, fertilizer is made in the dehydration fermentation.At last,, put into treating pond with sedimentary silt, metal etc. (with machinery for suitable), select metal after, pulverize, sieve, clean, do building materials with or topple over, in the filtering water and flocculation treatment, use repeatedly after the additional deficiency.Throw out filters the back organic fermented product of mixing and makes fertilizer usefulness.In addition bamboo and wood, plastics, the film of sorting being heated up 100～500 ℃ adds a little soda ash, with valuable solvent recuperation and sub-elect bamboo and wood and carbide.Reclaiming solvent is the solvent good material of making paint, coating, is worth higher.
Example two:
With domestic waste 1T,, use the strong acid sterilization, acidifying with the aqueous solution 5T mixed dissolution that adds (giving up) sulfuric acid 5%.Sub-elect bamboo and wood, plastics, the film of light specific gravity in the dark pond of 3m, heating up 100～500 ℃ adds a little caustic soda, sub-elects bamboo and wood and carbide, reclaims the solvent of paint, coating; Again the mashed vegetables of half suspended substance, rotten thing are put into and filtered attached pond, pulverize, filter, with a little ammoniacal liquor neutralization, form fertilizer, last, throw out is selected the metal post neutralization earlier clean, make building materials usefulness, the merging filtrate throw out, drying is made special-purpose flowers and plants, tobacco leaf, fruit tree fertilizer.
Example three:
With domestic waste 1T, progressively add in the pond of the dark 2m of 5T for preparing with buck, progressively isolate the bamboo that floats on the face with machinery while stirring, wood, plastics, vacuolar membrane, film and mashed dish, because comparatively small amt, can select bamboo earlier with half artificial way, wood obtains plastics with vacuolar membrane, film, woven bag etc., with plastics, film, 100 ℃ of compression mouldings of intensification such as woven bag, make reworked material, bamboo, carpentery workshop fuel, vacuolar membrane heats up and plastics, film is handled together, direct heat is dissolved in the solvent, will rot dish, rotten thing is pulverized with pulverizer, sieve, filter, the fertilizer base-material is made in the neutralization fermentation.After removing solvent, a little metal is partly manually selected, stone is pulverized, is filtered, and makes building materials.
This method great advantage is: avoided making the Organo-bio-thing such as mashed dish, rot living, animal, low temperature burns Change the bacterial reproduction of formation, not only eliminated smog, also make venomous injurant such as the large intestine of those low temperature breedings Bacterium, even carcinogenic substance Er Evil can not produce, and can be used as production up to standard fully.
Claims (9)
- Its content of aqueous solvent method for sterilizing and classifying life garbage in urban area and feature are divided following several aspect:1, make solution with natural water or tap water, suitably add industrial chemicals such as strong acid for sterilizing, highly basic is made sterilant, in order to improve the effectiveness of composting, disinfectant uses sulfuric acid (give up), liquefied ammonia for fitting.
- 2, the various materials of each domestic waste may be inconsistent, can according to practical situation determine water solvent what, the degree of depth will be arranged in principle, ratio less than solvent more than 3 times organic screening thing for suitable.
- 3, the leeway that material should have secondary to divide again after the sorting is in order to specifically selected again.
- 4, domestic waste film, plastics, vacuolar membrane, woven bag ratio are more and more, account for about 10%, optionally reveal intensifications, add the solvent that catalyzer is formed with usefulness, as it is also profitable to make reworked material after selecting, but equipment is greatly relatively.
- 5, organism (as mashed dish and putrefaction), composting is mainly nitrogenous, phosphorus, make fertilizer except that basic nitrogen, phosphorus, potassium content after doing fermentation or wet fermentation, also have an amount of active bacterium that there is improving effect in the soil, add fertile as ternary, be a kind of good fertilizer, use value is preferably arranged, ratio accounts for 30%～50% and does not wait.
- 6, settling, sort out metal earlier after, unified sieving, neutralization can be made building materials or topple over non-secondary pollution again after cleaning.
- 7, collect filtered water, add flocculation agent and handle, sterilization again (is suitable with acid flocculation agent such as ferric sulfate), drying is made efficient organic fertilizer, also can mix with other organism to add and make fertilizer.
- 8, after the surplus water treatment of Shou Jiing, can use repeatedly,, not have discharge of wastewater because existing appreciable loss must replenish ability circulation usefulness.
- 9, but present method is removed perfect combustions such as firewood, bamboo piece, does outside the fuel, does not use the low-temperature decomposition organism, as the carbohydrate of mashed dish, thus do not produce toxic smog and harmful germ, as Er Evil etc.Perfect combustion temperature such as wood, bamboo can not be lower than 800 ℃, even a little flue dust is arranged, can make air inducing heating of plastic, film, vacuolar membrane usefulness, and smokeless production is accomplished in dedusting again.
