Abstract

The invention relates to a method for carrying out comprehensive treatment on household waste, excrement and urine of people, livestocks and domestic fowls and water treatment sludge to produce an organic fertilizer, which comprises the following steps: separating out organics which can be used for producing the fertilizer in household waste by a method of arranging and sorting separately; after carrying out fine processing on the organics, mixing the organics with the excrement of people, livestocks and domestic fowls; collecting all waste of an abattoir and the water treatment sludge to carry out mixing and stirring; feeding the mixture into a large-scale underground storage tank to generate masses of biogas; carrying out fertilizer standardization treatment on the decaying fertilizer by a detecting test station; and transferring the obtained safe and nuisanceless multi-element quick-acting organic fertilizer to vegetable bases and farms by a pump through pipelines (the pipe network) or selling the obtained organic fertilizer.

Description

Domestic refuse, people, animal, brid guano urine, the comprehensive treating process of water treatment slag liquid become the method for fertilizer

Technical field: environment protection, recycling economy.

Background technology:, and topmostly have only three kinds of landfill, burning and compostings though at present there is multiple mode in the whole world to the processing of domestic refuse.To the processing of human excrement, have only water treatment, and do not have which big and medium-sized cities it to be sold out, samll cities and towns particularly at all without any the processing means, to the drainage of aquaculture and a waste of slaughtering, only let alone to pollute; The slag liquid of water treatment mostly is landfill.The common feature of above-mentioned treatment process: 1, cost height, lose more than gain, continue to pollute.2, destroyed picked-up and give back and animals and plants between the balance of food chain.3, the water after the water treatment is the middle water of substandard, so it remains polluted water, is the greatest contamination source to three lakes and other water systems.

Goal of the invention: will be reversed and cause the treatment process of severe contamination, reverse again: because existing treatment process to human excrement and domestic refuse, it is the reverse process method that violates the rules of nature, so cause so (pollution) big trouble, it meets along the person prosperous, a kind of social law that contrary person dies.Contained multiple element is that crop needs most, other impayable good fertilizer in them, organic component in the domestic refuse is become non-harmful multielement quick-acting organic fertilizer material and biogas with the movement of human excrement, aquaculture, the waste of slaughtering the field, the slag liquid comprehensive treating process of water treatment, basic realize picked-up and give back and animals and plants between the balance of food chain, no longer be the most insoluble source of pollution of environment.

For achieving the above object, solve by the following technical solutions:

A, formulation corresponding regulations are guaranteed to implement.

B, domestic refuse divide three partly to place from the source: recyclable usefulness again, deleterious and can make the organism of fertilizer.

C, to the collection of human excrement, with patent of invention ZL200410034448.1, ZL200910144911.0, the ZL200910179635.1 that I have applied for, they are to exempt from sitting wc pan and the squatting wc pan that water dashes.

After the movement of D, aquaculture and the waste gathering of slaughtering with the slag liquid of human excrement, water treatment with made rough machined domestic refuse, comprehensively carry out fragmentation, stirring, corruption, guarantor's fertilizer, getting fat and obtain stdn fertilizer, deliver to agricultural place by pipeline (pipe networkization).

Beneficial effect:

1, changes the treatment process that is reversed, saved the investment of having no way out in a large number.

2, save a large amount of tap water.

3, " organic fertilizer " book introduction of publishing according to agriculture press, 1580 jin of 1 year excretory fecalurias of grownup can be executed 0.07 hectare, produce more food 100 jin, and present national urban population reaches 700,000,000 more than, calculates to draw to increase production how much grain.

4, improve the soil, also the original quality of crop.

5, the chemical fertilizer of saving about 80%, the whole nation will have the soil more than 800,000,000 mu to be benefited, and rely on chemical fertilizer no longer fully.

6, the processing power about 70% being arranged in the water treatment is in the processing that is used in human excrement, so significantly reduce the pollution to water body of the investment of water treatment and middle water.

Below in conjunction with drawings and Examples the present invention is described in further detail:

Fig. 1 is process flow sheet of the present invention (because of literal and arrow mark is arranged among the figure, so do not represent with Arabic numerals).

It conscientiously is the basis that makes a good job of everything, rules are exactly conscientious, meet the thing of the natural law as long as conscientiously just necessarily can make a good job of it, implemented well for guaranteeing this project, must work out relevant law and regulations system, though it is not a technology contents of the present invention, it is the absolute condition that guarantees that the present invention can implement to put in place.

The domestic refuse of our country is a mixed type, and it brings very big difficulty to classification, and domestic refuse is that people are self-inflicted, so everyone has a responsibility for and obligation is resolved its outlet.Fig. 1, domestic refuse splits the place: the rubbish container bucket of family, public place, food and drink shop, enterprises and institutions working space, school, machine-operated office space etc. must be divided into organism, nuisance and regenerant three classes according to splitting content.Family uses own exhausted shopping plastics bag as far as possible, stick the non-setting adhesive paster that is printed on the number of respectively living that government is sent out, the public place plastics bag that is printed on address and numbering, other will buy the plastics bag that is printed on organization from environmental administration, receiving the rubbish people can pinpoint the problems when falling bag, so that call to account, fine or have a power failure (can not influence people's basic life because have a power failure), can guarantee the quality of classification like this, the convenient processing, save investment (moral home-made classification machinery is advanced in the world, and it also can only be told about 50%).Split in the content, nuisance represents that with A nuisances such as the refuse battery of telling, fluorescent tube account for 5%, landfill, regenerant represent that with B stationery wherein, rubber, metal, fabric, glass, plastics etc. account for 45% recovery and use, organism is represented with C, the waste that locate it comprises that the kitchen is surplus, surplus, the food market of food etc., the processing presort is sorted out A and is returned A, B returns B, with an amount of sanitary sewage of the broken adding of C, stir into the pumping state, through dropping down sieve

Water treatment slag liquid enters and drops down sieve

Nightsoil collection's mode, applied for patent of invention with me, fixed multi-functional don't water sitting wc pan ZL200410034448.1 or the direct-insert odorless, aseptic, exempt from water flushing water closet ZL200910144911.0, direct-insert odorless, sterile water-free flushing squatting closet ZL200910179635.1, through the fecaluria collection tube, enter underground temporary storage pond, fecaluria is storing up in the pond, when liquid level is raised to setting height temporarily, utilize the effect of ball float, with the power connection of pump, pump enters fecaluria warp let-off fragmentation to drop down sieve

The movement of aquaculture and a waste of slaughtering (factory), the process fragmentation enters drops down sieve

Be stirred into the C of pumping state in the domestic refuse, water treatment slag liquid, the movement of broken back and aquaculture and a waste of slaughtering (factory), all through and dropping down sieve, remove fail broken as plastic ties, string rubber or the like, send to landfill, send other mixture to mixing pit by pump, in the pond, throw in 3-5% calcium superphosphate or gypsum and per hundred jin of adding 5-6 two green vitriols (being ferrous sulfate) and an amount of straw powder again and play getting fat, protect the fertilizer efficiency fruit, also add an amount of ammoniacal liquor or urea and be pumped into agitated pool, stir into uniform mixture, be pumped into large-scale underground storage pond again, seal corruption at Chu Huachi, weed seed, worm's ovum, germ all is killed, realize harmless treatment, produce a large amount of biogas simultaneously, be sent to the user by methane station, through certain hour, what become thoroughly decomposed nuisancelessly (often contains the heavy metal that exceeds standard in the water treatment slag liquid, just insignificant in big quantity) multielement quick-acting organic fertilizer material, stand after testing by pumping, detect principal element, nitrogen, phosphorus, the content of potassium etc., carry out standardization again, it is exactly the fertile situation of need according to each surrounding city soil, suitably add chemical fertilizer and replenish, be sent to the vegetables base by pump through pipeline at last, the farm, the point of sale.

This fertilizer is the method for available press filtration also, obtains pure liquid state and solid-state two kinds of fertilizer.

Whole pipe networkizations are implemented in the technical process of present method.

Annotate: in above-mentioned, have wait, or the like occur because the unusual complexity of the composition in the composting, this goes out helpless.
