Abstract

A method for converting wastes into a high-quality fertilizer mainly adopts the wastes of kitchen compostable organic refuse in household refuse and comprises the following steps: 1, waste classification and selection; 2, waste crushing; 3, lime stirring and ground ash stacking; 4, dust heap surface mud pasting. The proportion of crushed waste particles to quicklime powder to ground ash powder is (5.5-6.6):(1.8-2.5):(1.3-1.8), the crushed waste particles are mixed with quicklime powder and ground ash powder, the mixture is stacked to be about 1-1.5 m, the bottom is appropriately pyramidal and about 1.5-2 m, the surface of the stacked waste heap has to be pasted with a layer of mud of 2.3 cm in thickness, and then covered with a layer of grass, and after that, the waste heap is placed for about one year. The method avoids environmental pollution, and a fertilizer formed by the waste heap is a high-quality fertilizer which can promote crop growth.

Description

A kind of is the method for fertilizer by garbage conversion

Art

The present invention relates to a kind of waste disposal method, especially a kind of is the method for fertilizer by garbage conversion.

Background technology

At present, both at home and abroad to the way that the improvement of rubbish has had some more feasible, as arranged refuse landfill, rubbish biological compost and waste incineration and generating electricity etc., these waste disposal methods play certain active effect to the recycling of rubbish and environment protection.But, due to technology and input cost aspect, cause and use not yet comprehensively perfect to the harmless Billy of rubbish both at home and abroad.What adopt as the present invention is that the method for fertilizer has no report by garbage conversion.

Summary of the invention

In order to improve the harmless treatment of rubbish further, reduce rubbish to the pollution of environment, simultaneously in order to widen the production ways of fertilizer further, the invention provides a kind of is the method for fertilizer by garbage conversion, the method not only can carry out harmless treatment to rubbish, and this innocent treatment procedure by can be fertilizer by garbage conversion, be agriculture production service, rubbish turned waste into wealth.

A kind of is that the method for fertilizer has following several step by garbage conversion:

One, refuse classification and selection;

Two, garbage crushing;

Three, lime and ground ash stacking is mixed;

Four, mud is stuck with paste on scrap heap surface.

Its main technical points:

One, refuse classification and selection: the composition of China's domestic waste is mainly divided into three major types: 1. can rotten organic waste, this kind of rubbish is based on more than kitchen; 2. flammable organic waste, this kind of rubbish comprises plastics, waste paper, leather, wood chip, dry goods etc.; 3. inorganic refuse, this kind of rubbish comprise cinder, brick and tile, grey, glass, metal etc., above-mentioned three major types rubbish is classified, the present invention's rubbish used mainly refer to more than kitchen can rotten organic waste.

Two, garbage crushing: can pulverize by rotten organic waste, become granulated garbage.

Three, lime and ground ash stacking is mixed: after the granulated garbage after pulverizing will mix the ground ash of calcium lime powder and building waste after crushed, could stack, the ratio of granulated garbage and raw ashes and ground ashes is 5.5-6.6: 1.8-2.5: 1.3-1.8, during stacking, one deck calcium lime powder first spilt by bottom, then, the granulated garbage mixing calcium lime powder and ground ashes thoroughly is stacked, and about the scrap heap of stacking take height as 1-1.5 rice, basal diameter is advisable for the taper about 1.5-2 rice.

Four, mud is stuck with paste on scrap heap surface: the mud that a layer thickness is the pulpous state of 2-3 centimetre is pasted on the scrap heap surface of putting well at heap over, then covers one deck grass.Pilling up time is about 1 year.

The invention has the beneficial effects as follows: garbage crushing is become particle, rotting and natural decomposition of rubbish can be promoted, and the stacking of rubbish, the heat that in rubbish, bacterial metabolism produces makes scrap heap temperature raise, the generation impelling the nematode in rubbish, acarid, earthworm etc. biological and activity, the generation of these biologies and metabolic activity, impel scrap heap to form soil ulmin compost.And unslaked lime is grey with ground on mixing in scrap heap, the effect of sterilization, moisture absorption, intensification can be played in scrap heap, promote the natural decomposition of garbage compost, layer of mud is pasted at fertile out-pile, effectively can intercept the rancid smell that rubbish gives out in natural decomposition process, reduce its pollution to ambient air, at surface cover last layer grass, the dry and cracked of mud can be postponed.

Claims

1. be a method for fertilizer by garbage conversion, it comprises several step: one, refuse classification and selection; Two, garbage crushing; Three, lime and ground ash stacking is mixed; Four, mud is stuck with paste on scrap heap surface; It is characterized in that: one, refuse classification and selection: can rotten organic waste, flammable organic waste, inorganic refuse classify, the present invention's rubbish used mainly more than kitchen can rotten organic waste; Two, garbage crushing: can pulverize by rotten organic waste, become granulated garbage; Three, lime and ground ash stacking is mixed; Granulated garbage after pulverizing could be stacked after will mixing the ground ash in calcium lime powder and building waste after crushed, the ratio of granulated garbage and raw ashes and ground ashes is 5.5-6.6: 1.8-2.5: 1.3-1.8, during stacking, one deck calcium lime powder first spilt by bottom, then the granulated garbage mixing calcium lime powder and ground ashes thoroughly is stacked, the scrap heap stacked is about 1-1.5 rice with height, and the taper about basal diameter 1.5-2 rice is advisable; Four, mud is stuck with paste on scrap heap surface, and the mud that a layer thickness is the pulpous state of 2-3 centimetre is pasted on the scrap heap surface of putting well at heap over, and then cover one deck grass, pilling up time is about 1 year.
