Description

Method with producing complex fertilizer from night soil

Technology is handled and utilized to we's ight soil owned by France.

Since ancient times, the peasant just utilizes human faecal mass to make fertilizer, to increase the output of farm crop.Society constantly advance and agriculture production technology improve constantly in the process, human faecal mass becomes more and more important to the production-increasing function of farm crop, the peasant updates the method for using human faecal mass.But this method changes not quite so far, and now general is being deposited in behind the collecting dung together, and the fermentation of giving free rein to is used preceding bulk being beaten with the farm implements artificial and is to be applied to the soil afterwards by fritter.This primary, traditional fertilizing method are extensive, not only apply inequality, and since manure fermentation not exclusively, not thorough, wherein effective constituent can not be given full play to effectiveness, causes the waste of fertilizer, simultaneously, be not easy to storage, transport and use, bring many inconvenience to the peasant.The method of this backwardness should be improved.Especially the chemical fertilizer shortage of current China, it is limited to plough the soil, and increase crop yield is the key that realizes agricultural modernization by every possible means.At present, vast farmers is used as use chemical fertilizer as the main method of volume increase more, this not only adds the contradiction that has swashed the chemical fertilizer supply and demand, and too much, the secular chemical fertilizer of using, and makes organism minimizing in the soil, the hardening soil more seriously causes the pollution of farm crop, forms public hazards; Especially the greengrocery crop is more outstanding.Simultaneously because the fertilizer price height, increase the input of agricultural, relative minimizing peasant's the production-increasing function of income chemical fertilizer, cause peasant's pursuit blindly to use chemical fertilizer more, and ignored using of farm manure, and advocate applications of farmyard manure energetically, be one of major measure of agricultural produce from now on.Human faecal mass is a part effective, the most maximum in the farm manure, all fail fully to obtain to utilize in the rural area, city, therefore, with new method handler's ight soil, it is made composite fertilizer, bring into play the fertilizer efficiency of ight soil to greatest extent, the shortage of alleviation chemical fertilizer, pollution abatement, enhancing soil fertility, the output that increases, raising farmers' income are had tangible economic implications and social effect.

Purpose of the present invention is to provide that a kind of technology is easy, less investment, is easy to popularize, the method with producing complex fertilizer from night soil can suitability for industrialized production, that agricultural development had distinct economic and social benefit.

Accompanying drawing is seen in the technical process of the inventive method.

Technical process below in conjunction with accompanying drawing is described the inventive method:

1. stir, pulverize, mix:

Human faecal mass water content does not wait mixes under agitation condition, and solid substance is wherein disperseed under the effect of whipping force; At stirring, blended simultaneously, add known sterilizing agent, sterilant kill pathogens, parasite, mosquitos and flies ovum, prevent generation and the breeding of mosquitos and flies, worm maggot.Through stirring fully, pulverizing is closed and be mixed into dense thick starchiness thing most.

2. fermentation:

The starchiness thing of ight soil can ferment under field conditions (factors), also can be at the artificial condition bottom fermentation, and artificial fermentation's Controllable Temperature is built in 40～80 ℃, and fully addling with wherein ight soil toilet paper etc. is fermentation termination.

During the fermentation, produce higher temperature, again further the mosquitos and flies of kill pathogens, parasite and generation, breeding, worm maggot.

3. dry:

Dry can nature or artificial condition under carry out, artificial seasoning is carried out under material turning, its temperature is controlled at 60～80 ℃, can form and keep definite shape with dry thing is dry terminal point, moisture content is 10～30%.

4. pulverize, sieve:

Above-mentioned dry thing is pulverized in pulverizer, and the final product granularity is sieved at 80～100 orders.

5. add additive:

Under stirring at normal temperature, adding can improve the material that soil can produce fertilizer efficiency again, can elect according to local resources, and add-on is 10～30%, as pit clay, and green mud, flyash, plant ash adds phosphorus fertilizer or potassium fertilizer then:

A. make base fertilizer usefulness, add the phosphorus element or the potassium fertilizer of gross weight 0.5～3%;

B. the usefulness of topdressing adds the phosphorus fertilizer or the potassium fertilizer of gross weight 5～10%.

Through the composite fertilizer of above explained hereafter, be meal.Can directly use or as commodity selling.

6. adding additives

Above-mentioned meal under agitation condition, adds gross weight 10～30% uniformly, contains the binding agent of adhesive 10～25%, and adhesive is selected plant amylum or soluble poly vinyl alcohol for use.

7. moulding:

The worker saves moulding with cold-forming, makes particulate state, and its particle diameter is 3～5 millimeters, and is dry under 60～80 ℃ of temperature then.

Utilize present method, can produce in the open, can suitability for industrialized production.Suitability for industrialized production should be carried out in airtight equipment, and establishes open air exhaust equipment.

To animal excrement, as domestic animals and fowls ight soil, utilize present method, production composite fertilizer that can be same.

Utilize method production of the present invention composite fertilizer, make the methodological scienceization of making fertilizer with ight soil, and can suitability for industrialized production, bring into play the fertilizer efficiency of ight soil to greatest extent, be convenient to storage again, transport and use; Having alleviated chemical fertilizer contradiction in short supply simultaneously, eliminated and to use the public hazards that chemical fertilizer causes, improved soil regime, improved crop yield, increased farmers' income, is significant improvement traditional, the applications of farmyard manure that falls behind.Present method technology is easy, and less investment is easy to popularize, can manual production, also suitability for industrialized production that can be large quantities of.Having remarkable economic efficiency and social benefit, is one of new, effective measures of increasing both production and income in the agricultural.

Claims
