Process for producing liquid organic fertilizer

Abstract

The invention belongs to the field of production processes of organic fertilizers and particularly relates to a process for producing a liquid organic fertilizer. According to the process, a fermentation box, a heat preserving device, a stirring device and a power device are adopted. On one hand, high-temperature steam is introduced into food wastewater and a solid-state fertilizer for sterilizingtreatment, so that the influence on a fermentation environment caused by action of infectious microbes on fermented substances is effectively lowered, the quantity of the infectious microbes is reduced, the production efficiency is prevented from being too low, and the quality of product is effectively improved; on the other hand, after high-temperature steam sterilization, the fermented substances in the fermentation box are subjected to acidity / basicity detection, the fermentation environment in the fermentation box is adjusted according to a detection result and is suitable for the survival of fermentative bacteria, the action of the fermentative bacteria is exerted, the production efficiency is increased, and the quality of product is improved; and the process is simple and efficientin production, the wasting of resources is avoided, and the natural environment cannot be affected.

Description

technical field [0001] The invention belongs to the field of organic fertilizer production technology, in particular to a liquid organic fertilizer production technology. Background technique [0002] In the process of food production, especially the production of soybean products, a large amount of wastewater will be generated. Wastewater is rich in organic matter such as oil, protein, starch, and colloidal substances. It has extremely high nutritional content and is a very useful resource. However, for a long time, most of the wastewater has not been effectively utilized, and some are even discharged directly. On the one hand, it causes waste of resources, and on the other hand, because the organic matter content in the wastewater far exceeds the environmental protection discharge standard, it will cause serious environmental pollution. According to scientific experiments, food waste water can be used as a raw material for the production of liquid diluted organic fertilize...

Problems solved by technology

However, most of the waste water has not been effectively utilized for a long time, and some are even discharged directly. On the one hand, it causes a waste of resources, and on the other hand, because the organic matter content in the waste water far exceeds the environmental protection discharge standard, it will cause serious environmental pollution.

According to scientific experiments, food waste water can be used as a raw material for the production of liquid diluted organic fertilizers, but there is indeed a lack of a production process that can convert food waste water into liquid diluted organic fertilizers efficiently, conveniently and quickly. According to the existing technology, the production process is tedious and complicated. The labor intensity is high, and the production process is prone to contamination by bacteria, which reduces the quality of organic fertilizers
