Abstract

The invention relates to a process for making organic biological fertilizer, wherein organic waste are used for organic fertilizer manufacture through the steps of granulating, fermentation, and drying free. Compared with the conventional process for making organic fertilizer, the invention realizes simple process, minimized investment, lowered cost, shorter manufacturing cycle, and higher efficiency.

Description

Alcohol is sent out in elder generation's granulation, back, utilizes organic waste to make the novel process of granular biological fertilizer

Technical field

The present invention relates to the novel process of production environmental protection organic bio-fertilizer in the biological fertilizer field.

Background technology

Population, resource, environment are the key subjects that mankind nowadays society faces, along with improving constantly of the people's lives level of consumption, feces of livestock and poultry, municipal wastes, mud and industrial organic waste also constantly increase, to urban environment and agricultural components serious threat, recycling how, the expert has carried out extensive studies for this reason both at home and abroad, obtained certain achievement, but because the investment of these methods is big, running expense is high, have a big risk, commodity poor performance (powdery, long column shape), benefit are low, general enterprise is difficult to bear this pressure.

Summary of the invention

Purpose of the present invention is exactly in order to overcome above-mentioned deficiency, with " recycling; capacity chemical control system; minimizing is handled; harmless treatment; ecology development; cheapization improvement " is principle, turn harm into good, turn waste into wealth, utilize first granulation, secondary fermentation, the novel process of exempting to dry, the industrial or agricultural organic waste is manufactured organic bio-fertilizer, this process reform the making method of traditional technology, technology is simple, less investment, with short production cycle, the commodity performance is good, high efficiency, be the once great technological revolution of organic fertilizer production field, can produce bigger social benefit and economic benefit.

Embodiment

1, utilize organic waste to make the novel process of organic bio-fertilizer, it is characterized in that first granulation, stoving process is exempted from secondary fermentation.It mainly is to finish by following steps:

(1) proportioning raw materials: make it reach best granulation, fermentation condition:

In A, the waste, organic content is between 40～80%;

B, moisture content are controlled between 50～30%;

C, C/N ratio is controlled between 25～35;

The phosphorus ore containing matter of D, adding about 5%;

E, pH value are controlled between 6.5～8;

The microorganism quick rotting agent of F, adding 1～2 ‰.

(2) with joining raw material send into and carry out broken granulation in the granulating disc that has shredder assembly, make the particle of desired size.

(3) the bright fertile aerobic fermentation of piling up of the particle that will make.

(4) control its leavening temperature, the temperature of utilizing its fermentation to produce is with the water evaporates of fertilizer heap.

(5) drop to normal temperature when compost temperature, section has a large amount of white hyphas, and moisture content has just been finished the manufacturing processed of bio-fertilizer 20% when following.

2, Fig. 1 is technological process of production figure of the present invention.

The present invention compares with traditional handicraft, has following good effect:

1, first granulation reduces traditional fermentation, drying, broken program;

2, the production cycle shortened more than 20 days;

3, reduced by about 50% production site;

4, ventilation is good between the particle, is beneficial to aerobic fermentation, and fermenting speed is fast, and the journey of becoming thoroughly decomposed is substituted the bad for the good and even, and nutrient loss is few, and the fertilizer efficiency height is used safer;

5, facility investment is few, and business risk is little.Unit product facility investment volume reduces more than 5 times, has only reached 0.75 ten thousand yuan of/ton dry product;

6, adopted and exempt from drying technology, production energy consumption is low, and useful active bacterium height in the fertilizer has met or exceeded the standard of the bio-fertilizer of national regulation;

7, leavening temperature height, the hold-time is long, has avoided secondary pollution;

8, productive expense is low, and labour intensity is little, reduces cost more than 200 yuan/ton than traditional technology;

9, finished product fertilizers is the rounded grain shape, and the commodity performance is good, use conveniently, and high efficiency, market potential is very big;

10, suitability is wide, and large and small livestock and poultry farm, life, industrial or agricultural organic waste composting all can use.

11, create utmost point favourable condition to environmental improvement work.

In sum, China has trillion tons industrial or agricultural organic waste, if take this technology to handle, will reduce environmental improvement input more than more than one hundred million units to China, bring the economic benefit of several hundred million units to enterprise, bring infinite social benefit for the ecological agriculture, human lives.

Claims

1, a kind of first granulation, secondary fermentation utilize organic waste to make the novel process of granular biological fertilizer, it is characterized in that, and first granulation, stoving process is exempted from secondary fermentation, and it mainly is to finish by following steps:

In A, the waste, organic content is between 40-80%

B, moisture content are controlled between the 50-30%

C, C/N ratio is controlled between the 25-35%

The phosphorus ore containing matter of D, adding about 5%

E, pH value are controlled between the 6.5-8

The microorganism quick rotting agent of F, adding 1-2 ‰

(4) control its leavening temperature, the temperature of utilizing its fermentation to produce is with the water evaporates in the compost.

2, first granulation according to claim 1, secondary fermentation utilize organic waste to make the novel process of granular biological fertilizer, it is characterized in that, the main technique principle is as follows: the organic waste that will glue shape is after the proportioning granulation, carry out heap fermentation, make it to become thoroughly decomposed and dry again again, sieve, just become granular ecological organic fertilizer.
