Efficient biological stuffing and preparation method thereof

Abstract

The invention relates to an efficient biological stuffing and a preparation method thereof and relates to the field of a biological stuffing technique. The stuffing is prepared fromthe following raw materialsin parts by weight: 300-400 parts of wood, 30-45 parts of bark, 20-40 parts of rice hull, 30-50 parts of straws, 80-100 parts of plant ash, 70-80 parts of rice chaff ash, 20-30 parts of leaf mold, 15-25 parts of bone meal, 50-80 parts of compound fertilizer and 35-65 parts of bio-organic fertilizer. The varieties of microorganisms allowed to grow by the stuffing prepared by the invention are abundant; a big specific area is supplied to the inhabiting and growing of microorganisms; the nutritional ingredients are reasonable (N, P, K and microelements); the water absorption is excellent; the stuffing is free from odor; the adsorbability is excellent; the structural uniform porosity is large; the materials are easy to acquire and low in cost; the stuffing is anti-aging; running and maintenance are simple.

Description

technical field [0001] The invention relates to the technical field of biological deodorization, in particular to a biological filler and a preparation method thereof. Background technique [0002] Biological deodorization is to use the action of microorganisms on the specific surface area of ​​the carrier filler to deodorize under suitable conditions. The odorous substances are first absorbed by the filler, and then oxidized and decomposed by the microorganisms attached to the filler, thus completing the deodorization process of the odor. In order to keep microorganisms highly active, a good living environment must be created for them. For example: suitable humidity, pH value, oxygen content, temperature and nutrient content, etc. The actual production design requires that the relative humidity of the carrier filler is kept at 80-95%, so the raw sewage or primary sedimentation tank effluent is often used to provide water and nutrient sources. However, the existing filler...

AI Technical Summary

Problems solved by technology

However, the existing fillers generally have poor adsorption capacity and cannot provide sufficient nutrients for the attached microorganisms, making the deodorization effect poor and unable to meet the expected requirements.
