Oil-based phosphorus biological fertilizer and preparation method thereof

Abstract

The invention discloses an oil-based phosphorus biological fertilizer comprising the following components: a grease raw material, a phosphorus fertilizer and humic acid, and also discloses a preparation method of the biological fertilizer; the preparation method includes high temperature sterilization of the grease raw material, crushing of the phosphorus fertilizer, mixing of the two raw materials and adding of the humic acid, pelleting, particle drying, screening and other steps; according to the oil-based phosphorus biological fertilizer and the preparation method, the grease raw material is used to prepare the biological fertilizer, grease from the producing process of fur clothing, leather and the like can be greatly recycled, and can be converted into nutritional ingredients that can be absorbed by crops, the soil fertility is improved, the crop growth is promoted, the quality of agricultural products is improved, the oil-based phosphorus biological fertilizer is contribute to prevention of water pollution caused by emissions of the grease, and is in response to the waste recycling policy suggested by the state.

Description

technical field [0001] The invention relates to a biological fertilizer, and also relates to a preparation method of the biological fertilizer. Background technique [0002] With the improvement of living standards, people's consumer goods are also developing rapidly. In recent years, more and more people are fond of leather clothing products such as fur, mink, and cowhide. However, in the processing of the above-mentioned clothing fabrics, such as During the processing of mink fur, the oil in mink fur needs to be treated, and the resulting waste water contains a large amount of animal fat. If it is directly discharged into the external environment, it will seriously pollute rivers and groundwater resources over time, and even threaten residents. The safety of water, causes above-mentioned a large amount of grease wastes at the same time, and can't recycle, is unfavorable for responding to the energy rectification guideline of waste reuse proposed by the state.

[0002] With the improvement of living standards, people's consumer goods are also developing rapidly. In recent years, more and more people are fond of leather clothing products such as fur, mink, and cowhide.

If it is directly discharged into the external environment, it will seriously pollute rivers and groundwater resources over time, and even threaten residents. The safety of water, and at the same time lead to the above-mentioned large amount of oil waste, which cannot be recycled, which is not conducive to responding to the energy rectification policy of waste reuse proposed by the country
