Problems solved by technology

Phosphorus supplementation in aquaculture mostly uses products such as general calcium and double superphosphate. Due to the low utilization rate of phosphorus in the water environment, a large amount of such chemical fertilizers will be used, resulting in large changes in the pH of the water body, destabilizing the water environment, and not conducive to fish.

Embodiment 1

[0027] A kind of technology that utilizes Compo fermenter to process fresh pig manure to produce active phosphorus organic fertilizer for aquaculture, comprises the following steps:

[0028] (1) Raw material pretreatment: Mix 10% sawdust, 8% fermented return material and 0.5‰ starter, and then mix with 80% dry pig manure and 2% superphosphate to make moisture A fermented premix with a content of 75% and a pH of 7.5;

[0029] (2) Primary fermentation: Put the fermentation premix into the silo of the fermentation machine from the top feeding port of the Compo S-90 fermentation machine for fermentation, adjust the valve size of the upper and lower air supply fans of the fermentation machine, so that the temperatures of the upper, middle and lower layers of the fermentation machine are respectively Control the temperature between 70-75°C, 60-65°C, and 50-55°C. The fermented premix is ​​fermented in the fermenter for 7-10 days and released from the discharge port to obtain a moistu...

Embodiment 2

[0034] A kind of technology that utilizes Compo fermenter to process fresh pig manure to produce active phosphorus organic fertilizer for aquaculture, comprises the following steps:

[0035] (1) Raw material pretreatment: mix 8% sawdust and wood bran, 10% fermentation return material and 0.5‰ starter, mix evenly with 80% dry pig manure, 1% heavy superphosphate , making a fermentation premix with a moisture content of 73% and a pH value of 7.5;

[0036] (2) Primary fermentation: Put the fermentation premix into the silo of the fermentation machine from the top feeding port of the Compo S-90 fermentation machine for fermentation, adjust the valve size of the upper and lower air supply fans of the fermentation machine, so that the temperatures of the upper, middle and lower layers of the fermentation machine are respectively Control the temperature between 70-75°C, 60-65°C, and 50-55°C. The fermented premix is ​​fermented in the fermenter for 7-10 days and released from the disch...

Abstract

The invention belongs to the technical field of biological organic fertilizer manufacturing and particularly relates to a technology for treating pig manure and producing an active-phosphorus organicfertilizer for aquaculture through a Compo fermentation machine. The technology comprises the steps of raw material pretreatment, primary fermentation, aging and aftertreatment. According to the technology, the Compo machine is adopted for fermentation treatment, the manure treatment problem of a large-scale pig farm can be solved in time, the organic fertilizer good in quality and suitable for phosphorus supplement in aquaculture is produced, and the circular economy concept of turning waste into wealth is truly achieved; a flexible collection bag is adopted for treatment of an aging technology, operation is easily and conveniently conducted, the production efficiency is high, the product quality is relatively stable, and convenience is provided for large-scale application. According to the technology, fresh pig manure collected from the pig farm is directly used as a raw material, airing or other processes for reducing moisture are not needed, the labor can be greatly saved, and odorescape, nitrogen loss and environment pollution caused by airing of the fresh pig manure or other processes are avoided.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizer manufacturing, and in particular relates to a process for producing active phosphorus organic fertilizer for aquaculture by using a Compo fermenter to process pig manure. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly. From the original total development type to large-scale and intensive development, a large number of small and medium-sized aquaculture enterprises (households) will be eliminated by the market and related policies. Aquaculture enterprises must be scaled and industrialized On the basis of improving scientific and technological innovation capabilities and improving unit productivity, we will seek development opportunities. With the promotion of large-scale farming, the environmental protection problems that arise with it seem to be becoming more and more serious. According to statistics from the Ministry of Agricu...
