Abstract

The present invention is the method of treating human excrement with flyash and producing excrement-flyash fertilizer, and belongs to the field of composite fertilizer. The present invention treats human excrement with flyash with the mineral fertilizer characteristic and excrement coating function and combines flyash and human excrement to produce granular composite fertilizer through mixing, high temperature extrusion to pelletize, drying, cooling, bagging and other steps. The composite fertilizer contains rich organic matters from human excrement and mineral elements from flyash, may be industrial produced and has multiple fertilizer effects.

Description

A kind of method and novel excrement ash particle fertilizer of handling feces of toilet with flyash

A kind of method and novel excrement ash particle fertilizer with flyash processing feces of toilet belongs to feces of toilet processing technology field and human excrement fertilizer and the fertile compound manure kind of mineral element field.The feces of toilet treatment process mainly contains the water punching method in the world at present: utilize three-grid septic tank microbiological treatment ight soil.Circulating water to flush method:, flush the toilet with biochemical and physical method for separation and decomposition ight soil and recycle water.Exempt from flushing method: utilization biochemical reactor microbiological treatment ight soil.Packaging method: ight soil packed into mould bag and seal processing up for safekeeping.Compost method: allow microorganism handle ight soil naturally the ight soil accumulation.Patent retrieval, application number has 01129167.2, the 01225195.3 99116692.2 01118610.0 existing feces of toilet methods of handling, ubiquity is not suitable for scale and utilizes manure resource, inconvenient operation, expense is high or can not intactly preserve various useful fertilizer compositions in the ight soil get off, as after biochemical treatment, ight soil has become soil ulmin, and it is serious wherein to play in the Mierocrystalline cellulose of loosing soil effect and the urine loss of nitrogenous fertilizer.Novel excrement ash particle fertilizer patent is picked up rope, have application number 89100043.7 94105972.3 96115572.8 to have inconvenient operation, expense cost height, the industrialization of incompatibility feces of toilet is produced and is used.

Flyash is that fine coal is through the residue behind the high-temp combustion, particle is tiny, particle diameter is generally less than 100 microns, be widely used in the harmless powdery substance of building trade, function with intensive suction, retaining, covering and parcel ight soil is again a kind of mineral substance fertilizer that is rich in the required mineral nutrient element of plant-growth.Select from July, 2002 " environmental science and technology " magazine, the 25th volume the 4th phase " plant nutrient occurrence status and application in the flyash " the present invention is the function treatment feces of toilet that utilizes the mineral substance fertilizer characteristic of flyash and intensive suction, retaining, covering and parcel ight soil.Method is ight soil to be inhaled hold in flyash, and parcel ight soil hides distributing of its foul smell and stop harmful proliferation of germs to reduce microbiological degradation ight soil, and the more complete preservation of various compositions is got off, and the two is combined into a kind of raw material of producing excrement ash compound manure again.Feces of toilet is a kind of extraordinary fertilizer and soil improvement agent, because there is the transportation trouble in it, so problems such as hygienic issues and use inconvenience are failed as chemical fertilizer so far in commodity circulation circulation and widely application, most of urban night soil enters rivers, promptly wastes resource and has polluted water quality again.Purpose of the present invention, be feces of toilet and flyash are mixed into a kind of, low cost, easy to operate, can the industrialization mass production and the new-type fertilizer widely used.Main contents are put into the flyash of limiting the quantity of, when going to toilet in the squatting wc pan of lavatory; the urine of urine is inhaled by flyash and held therein, and the ight soil of stool is wrapped up by flyash, hides distributing of its foul smell; after going to toilet, and squatting wc pan is opened downwards, and ight soil and mixture of fly ash are fallen into the preservation of excrement ash bucket.Dejecta treatment method to water closet; the liquid dung of septic tank will be entered; carry out solid-liquid separation; the usefulness of handling of flushing the toilet capable of circulation of purifying waste water, solid sediment ight soil mixes preservation with flyash, then excrement ash mixture is transported into fertilizer producing plant; ight soil by a certain percentage and flyash; and the micro-clay that has added adhesive effect stirs, and is transported to the high temperature Squeezinggranulator, makes dried particles fertilizer.High temperature is that institute ill mattress and microorganism in the ight soil are killed, and removes moisture and make ight soil suspend humic to decompose.

Major advantage, flyash is a kind of industrial residue utilization, and expense is cheap, handles ight soil water of can exempting to flush the toilet with it and can remove the biochemistry or the microbiological treatment facility of ight soil again from, fertilizer component that again can complete reservation ight soil, method simply are fit to the industrialization production of bio-toilet.Pure night soil improper fertilization easily injures plant, and flyash is filled and diluted ight soil, has created condition for industrialization utilizes the feces of toilet resource in a large number.Novel excrement ash particle fertilizer with ight soil and flyash are made has characteristics such as many fertilizer efficiency.Ight soil is handled implementation method: the lavatory is by house, health setting and go to toilet, electric apparatus control apparatus is different with general lavatory is, in the divider wall of men and women lavatory, install one and deposit the grey storehouse of depositing of flyash, depositing grey holding capacity of bin can deposit to go to toilet more than 2 months and use flyash, squatting wc pan is a Yangtze River Delta shape wide at the top and narrow at the bottom, can open and close downwards, be that one or several are deposited the bucket of excrement ash mixture below the squatting wc pan.Finite quantity in the time spent squatting wc pan is treated in the lavatory, and light gray or ravous flyash look pure dry and comfortable, has intercepted again that excrement ash bucket peculiar smell distributes in the lavatory below the squatting wc pan, a small amount of peculiar smell below the squatting wc pan in the excrement ash bucket have lead to the roof distribute the pipe diffusion.When going to toilet; the urine urine is stored in flyash; the ight soil proportion of stool is greater than flyash; be wrapped so be absorbed in the flyash immediately, and the perfect person that goes to toilet leaves squatting wc pan, and electronic inductor can be controlled squatting wc pan and open downwards; allow the excrement ash fall into the excrement ash bucket and preserve; and after closing,, continue stand-by by depositing the flyash of limiting the quantity of to the squatting wc pan input in grey storehouse.Also can adopt the push-switch red-tape operati.Excrement ash mixture was taken away once by environment-friendly vehicle in every month in the excrement ash bucket, deposit grey storehouse and generally inwardly adorned flyash every 2 months one time by the flyash tank car, the position of squatting is provided with a general lavatory, establishes 4 squatting wc pans of 5 men of woman, man's urinal is provided with in addition, and urine can directly flow into the excrement ash bucket by pipeline and store.Novel excrement ash particle fertilizer implementation method: excrement ash mixture is transported into factory, after sealing by cleaning foreign material, ratio allotment, stirring, high temperature extruder grain, dry cooling, pack, is exactly a kind of widely used novel excrement ash particle fertilizer.
