Biological organic fertilizer produced by using household garbage buried for years

Abstract

The invention discloses a bio-organic fertilizer produced by domestic garbage that has been buried for many years. Fertilizer is an important material guarantee for the development of high-yield and high-quality agriculture. The bio-organic fertilizer described in the invention is prepared from the following raw materials in parts by weight: garbage 1000 parts of nutrient soil, 5-10 parts of Japanese enzyme bacteria expansion bacteria, 4-8 parts of modified zeolite powder, 10-18 parts of dried chicken manure or duck manure, 16-22 parts of rice bran, 8-12 parts of phosphate rock powder . Stir the raw materials evenly according to the ratio and stack them for fermentation. Keep the temperature between 60-70°C on the first and second days, keep the temperature between 40-50°C on the third and fourth days, and keep it at room temperature on the fifth and sixth days. Get bio-organic fertilizers. The invention reutilizes the garbage that has been buried for many years, effectively improves the environment and reduces the production cost. It solves the problem of difficult site selection for the landfill required by the rapid increase of domestic garbage and the problem that the garbage occupies a large amount of land, so that the landfill site can be reused.

Description

technical field [0001] The present invention relates to the treatment of solid waste, in particular to a kind of fertilizer transformed from waste or garbage. Background technique [0002] Since the 1970s, my country has gradually begun to use the landfill method to dispose of municipal solid waste. Up to now, landfill has become the main disposal method of urban domestic waste in my country. The amount of urban domestic waste treated and disposed by landfill method accounts for more than 70% of the total amount processed. Several large-scale landfills have been built, and each landfill is filled with Hundreds of millions of tons of garbage have been imported. Because the landfill method has the advantages of low investment, simple process, convenient management, wide application range, and low maintenance cost, according to my country's economic and technological level and the composition of urban domestic waste, in a long period of time in the future, the disposal of urban...

AI Technical Summary

Problems solved by technology

The use of landfill to dispose of domestic waste will face several prominent problems: first, the amount of domestic waste is rapidly increasing at a high rate of 7% to 9% per year, and the area of ​​landfill required is getting larger and larger; second, the urban area The continuous expansion to the surrounding areas and the rapid rise of suburban land prices have made it more and more difficult to select landfill sites, and it is even impossible to find suitable sites. The landfill has reached or is about to reach the end of its service life, and the problem of landfill reconstruction and reuse is becoming more and more acute
