Problems solved by technology

However, most of the organic fertilizers produced and used in my country at present have low organic matter and nutrient content, and a small number of beneficial microorganisms. Therefore, people continue to study new solutions for bio-organic fertilizers and seek new products that improve crop yield and quality, which is not only beneficial to people. The physical health is also in line with the requirements of building a harmonious society in our country

Embodiment 1

[0020] This embodiment provides a kind of equipment for manufacturing biologically active water, such as figure 1 As shown, it includes an air flotation filter tank 1, an adjustment tank 2, a fermentation and decomposition tank 3, an aerated biological tank 4, and a product storage tank 5, and the above-mentioned tanks are connected to each other in turn.

[0021] The air flotation filter tank 1 is equipped with an air flotation filter device 14, and there are sludge 8 and microbial flora 10 inside. The tank is 1-3m away from the bottom and has a porous partition 11 connected with the adjustment tank 2; the adjustment tank 2 has a Microorganism generating device 6; fermentation and decomposition tank 3 communicates with adjustment tank 2 and aeration tank 4 through porous partition 11; aeration tank 4 sends the final product into the product storage tank without power through glass fiber non-woven filter plate 7 5; wherein sludge 8, microbial flora 10, volcanic rock 9 and aera...

Embodiment 2

[0023] The present embodiment provides a method for manufacturing biologically active water, which may include the following steps:

[0024] (1) The organic sewage is discharged into the air flotation filter tank 1, and the air flotation filter equipment 14 scrapes scum, discharges scum, and generates microbubbles, wherein the amount of microbial flora 10 in the sewage is 300-3000mg / L, the process The COD removal rate is 5-20%. The preliminarily treated sewage is discharged into the adjustment tank 2 through the porous partition 11 .

[0025] (2) The sewage flowing into the adjustment tank 2 will increase the oxygen in the sewage to 1-2.5mg / L through the action of factors such as the air supply pipe 13, the sludge 8, the fan 12 and the aeration equipment 15, and control the microbial generation equipment The amount of microorganisms produced in the sewage is 3000-8000 mg / L. Through this process, 10-30% of COD is further removed under the conditions of step (1), wherein the hy...

Embodiment 3

[0041] The present embodiment provides a method for utilizing the above-mentioned biologically active water to manufacture bio-organic fertilizers, adding 5%: 30%: 15%: 15% to pig manure, chicken manure, cow dung, grass charcoal, vegetable cakes, sawdust, and bran respectively. %: 5%: 15%: 10% weight ratio mixed evenly to make a mixture, then spraying concentration is 15% biologically active water 5%, while adjusting the pH to between 6.9~8.9; will add the mixture of biologically active water The stacking begins to ferment, and the stacking position formed by stacking the mixture is 25 cubic meters, with a height of 3 meters. After stacking, turn the pile once every 2 to 7 days (when the temperature in the pile reaches 50°C), carry out fermentation, and ferment again until the ripening is completed. The obtained decomposed materials are dried, crushed, screened, and packaged to obtain the final product.

Abstract

The invention relates to a biological organic fertilizer adopting microbial fermentation and a preparation method thereof. The method comprises the following steps: firstly uniformly mixing pig manure, chicken manure, cow manure, grass carbon, vegetable cake, sawdust and bran according to weight proportion, then adding biological active water with certain concentration, stirring uniformly, and simultaneously regulating pH to be 6.9-8.9 to start fermentation, overturning every 2-7 days after stacking (when the temperature in the stack can reach 55 DEG C), then stacking in a concentrated way for fermentation again until fermentation maturing is finished (the total time is 7-15 days), namely, the temperature does not rise any more; and drying, smashing, screening and packing the obtained material when the water content is lower than 20 percent, thus obtaining the product. The organic fertilizer not only can improve soil, replace chemical fertilizers, cause yield of crops to be increased and improve crop quality, but also can reduce the content of harmful element, eliminate pesticide residue in soil, and can improve saline-alkali soil.

Description

technical field [0001] The invention relates to a bio-organic fertilizer fermented by microorganisms and a preparation method thereof, belonging to the technical field of bio-organic fertilizers. technical background [0002] my country is a large agricultural country, with more than 2 billion mu of crop cultivation area and an annual need of more than 140 million tons of fertilizers. Due to the uneven level of agricultural development in my country, most agricultural crops currently rely on chemical fertilizers. According to relevant data, the average amount of chemical fertilizers in my country is 2.4 times that of the United States, 4.4 times that of Canada, 8.6 times that of Australia, and 9 times that of Russia. Extensive use of chemical fertilizers has brought good harvests to agricultural production, but it has led to a serious decline in the natural fertility of the soil and pollution of food and the environment, and further affects human health. In order to develop ...
