Abstract

The invention discloses a method of preparing a compound fertilizer by utilization of household garbage. According to the method, the method adopts the household garbage as a raw material, is capable of continuously forming an organic compound fertilizer with a certain standard by special treatment, is capable of overcoming secondary pollution and turning waste materials into things of value and is capable of timely treating the household garbage needed to be treated daily according to a planned capacity. The production cycle is within 24 h. The method is suitable for treatment of any household garbage.

Description

A kind of method of utilizing domestic refuse to make Chemical Mixed Fertilizer

Technical field

The present invention is specifically related to a kind of method of utilizing domestic refuse to make Chemical Mixed Fertilizer

Background technology

Domestic refuse is the problem that any development must solve, along with social progress, and the raising of environmental requirement, out-of-date direct landfill, even to abandon way be definitely impracticable to heap.And the screening that carry out in some place, compost (sending out alcohol) method is taken up an area greatly, the time is long, can not process in time continuously the municipal wastes that must process every day; Naturally burn and also relate to stationary furnace size, natural effect is poor, does not catch up with the excretion of urban development, can perform practically no function.

The invention belongs to and utilize the life rubbish utmost point as raw material, through special processing, can form to continuous effective the compoiste fertilizer of certain standard, mixed organic manure.Both can solve secondary pollution turns waste into wealth, and can immediately process according to planning capacity the usability methods of the domestic refuse that must process every day in city again.(production cycle is in 24 hours) present method is adapted to the processing of any domestic refuse.

Summary of the invention

One, screening

(1) sterilization (adding of germicide or sterilant) for the first time

(2) vibratory screening apparatus nature sorting size, after use again other facility separating plastic iron block etc.

(3) sieve: use the pulverizer of special type that organism was pulverized to certain order number sieve.

Two, sterilization: increase fertility with chemical reaction, synthetic processing.

1, according to crossing calcium method, city Waste Sulfuric Acid is adjusted to diluted acid, quantitatively adds organism and sieve rubbish, with strong acid sterilization, sterilization, this sterilization can all be killed as bacterium such as intestinal bacteria.Dioxins also can decompose.After add reciprocity ground phosphate rock and formed calcium class reaction.Present method be preferably dilute sulphuric acid (hydrochloric acid, disappear acid all can), moisture content is large, can form suspended organic matter, thus will part silt separately, improve organic content.

2, by the acid organic and inorganic calcium compounds of crossing of band, cross leakage, dehydration, with useless ammonia, salkali waste potassium water (as pressed alkali potassium without the available liquid giving up), it is neutral adjusting pH value, forms the composite fertilizer of certain content.As calibrated criterion by calculating input to add, reach trim point, be ideal data.Organism is higher, good sorting, and its effect is just better.

Three, as by organism by first send out alcohol add again after inorganic reaction effect substantially, reason is that organic bacterium field will be killed.Compoiste fertilizer (Chemical Mixed Fertilizer) after synthetic is due to after in thermal response, can spontaneous fermentation, as it is proper to add bacterial classification, more can improve organic effective force.

Example:

By 1 ton of municipal wastes, sorting remains approximately 0.8 ton after sieving, and wherein silt 50%.Organism is 0.4 ton, after decomposing, adds 40 kilograms of calcium superphosphate with quantitative diluted acid sterilization, forms approximately 0.5 ton of mixed organic manure, (isolating 0.4 ton of silt), add again useless ammonia, quantitatively neutralization, the mixture of formation organism and phosphorous acid Yiammonia composite fertilizer, in addition quantitatively potassium sulfate is Nitrogen, Phosphorus and Potassium, as sighting target is accurate, add 15% of Nitrogen, Phosphorus and Potassium and calculate, roughly should add 200 kilograms, ground phosphate rock, sulfuric acid folding hundred is calculated 85 kilograms, 600 kilograms of well-graded organism, separately add 100 kilograms of potassium sulfate.

According to above calculating, produce 1 ton of 15% inorganic content ternary fertilizer, 1.5 tons, application rubbish, husky 600 kilograms of spoil disposal.Adopt this law, just have the effect obviously addressing the above problem, and use properly, will, under minimum spending, from naturally biochemical development, deal with problems to greatest extent.

Year to process 10,000 tons of small city destructor plants, after the certain amount of money of investment, can form manually the expenses such as place, facility, in addition handling, annual meter is hundreds thousand of, if can, by wherein 40% becoming fertilizer, just reduce by 40% occupation of land, and can increase the sale price of 40% amount, 10000 tons is 4 kilotons, from sale price with 100 yuan of calculations with regard to 400,000 yuan, also just have 400,000 derating, if use well, also has the larger amount of money; If Coordination Treatment amount obtains benefit produce surely.

To saving your breath, by this, progressively improve and reclaim benefit way, both reduced occupation of land, input can be reduced to greatest extent again, and environmental protection non-secondary pollution can be accomplished, be that an investment risk is little, there is the way of actual effect.Owing to itself forming composite fertilizer in synthetic, then add organism and can be called compoiste fertilizer, mixed organic manure with its implication.

Claims

1. a method of utilizing domestic refuse to make Chemical Mixed Fertilizer, it is characterized in that: the screening unification of the main domestic refuse of the method is sieved (comprising pulverizing), to screen thing (after unified sieving), with strong acid (spent acid comprises sulfuric acid, hydrochloric acid, nitric acid) sterilization and disinfection, after used calcium working system, add ground phosphate rock suitable, generated calcium, with useless ammonia (ammoniacal liquor, liquefied ammonia or potash), carry out neutralization reaction again, generate organism, silt and phosphoric acid one ammonia, mixed organic manure, (has wherein been with binary inorganic composite fertilizer.

2. a kind of method of utilizing domestic refuse to make Chemical Mixed Fertilizer as claimed in claim 1, it is characterized in that: on above basis, add the not enough part of ternary as potassium sulfate or Repone K appropriate, be just ternary mixed organic manure (band inorganic composite fertilizer), strong acid is adjusted to the great diluted acid of moisture content, carry out silt and organism sorting, can first select organism more than 90%, rear mistake leaked, dehydration, again with ground phosphate rock according to than, after forming calcium, carried out ammonia neutralization or potash neutralization, form organism and inorganic composite fertilizer, Chemical Mixed Fertilizer, as reach Nitrogen, Phosphorus and Potassium standard, add not enough part (neutrality), be the ternary mixed organic manure of certain content, mixed organic manure after neutralization is stacked again, bacterial classification is sent out alcohol.

3. a kind of method of utilizing domestic refuse to make Chemical Mixed Fertilizer as claimed in claim 1, it is characterized in that: present method is in garbage treatment, use ripe acid, in alkali and principle, wherein strong acid effect is more much better than highly basic (as lime), again in conjunction with producing inevitable acid with composite fertilizer (inorganic), alkali N-process, reach sterilization, sterilization, build up fertility and reach certain standard (as Nitrogen, Phosphorus and Potassium 15% standard), by the speed of chemical industry building-up process, the sterilize utilization of effective combined organic, immediately, fast processing municipal wastes, form the compoiste fertilizer that nature needs, add and adjust again, up to standard, as the interpolation of ternary inorganic content 15%, as long as calculate the molecular weight of inorganic chemical industry, neutralization reaction is calculated addition suitably.
