Method for treating domestic garbage by establishing bioreactor through earthworms

Abstract

The invention relates to a method for treating domestic garbage by establishing a bioreactor through earthworms, which is applied to the field of domestic garbage treatment. A production method of the product comprises the following steps of: establishing the bioreactor according to the life habit of the earthworms, arranging 20,000 to 80,000 earthworms in each square meter of bioreactor, and culturing; sorting the domestic garbage, treating parts which can eaten by the earthworms, and mixing the domestic garbage, sludge and biological bacteria in a ratio to form an earthworm feed; putting 60 kilograms of prepared earthworm feed in each square meter of a culture bed of the earthworm bioreactor, and controlling the temperature of the earthworm feed on the culture bed to be between 15 and 25 DEG C, the humidity to be between 50 and 70 percent and the pH value to be between 6 and 8; and adding 60 kilograms of earthworm feed every other 6 to 10 hours, culturing for 50 to 60 days, and taking the mature earthworms out of the bioreactor. The earthworms are used for producing Chinese medicinal materials, health care products and agriculture, animal husbandry and fishery feeds, and earthworm excrement generated by the earthworms through metabolism is used for processing organic fertilizers. The method is novel and scientific in concept, a large-scale modernized earthworm bioreactor is established according to the life habit and growth characteristic of the earthworms, and the available parts of the earthworms are treated to form feeds for culturing the earthworms.

Description

Technical field: [0001] The invention relates to a method for using earthworms to build bioreactors for large-scale treatment of domestic garbage. Background technique: [0002] At present, various countries widely study and apply earthworms to prevent and control public hazards. In particular, the use of earthworms to treat waste has attracted the attention of various countries. For example, Japan, the United States, Canada, France and other countries have established earthworm farms as a supplementary system for urban waste treatment to solve the problem of environmental pollution in the suburbs. There are four main ways to deal with urban waste in various countries in the world: classified recycling, landfill, composting and incineration. Landfilling requires a large amount of land. At the same time, harmful components in garbage will also cause serious pollution to the atmosphere, soil and water sources, which not only destroys the ecological environment, but also seri...

AI Technical Summary

Problems solved by technology

Conventional waste disposal methods include incineration power generation, sanitary landfill, and composting. However, due to the constraints of my country's economic level and waste characteristics, these three methods are not suitable for vigorous promotion in my country.

The one-time investment of incineration power generation is too high, and the operating cost is high, which is only suitable for developed countries with high economic level; if the land occupied by sanitary landfill is not strictly implemented in accordance with international standards, it will cause secondary pollution after a few years, and the consequences will be more serious; The composting cycle is long, the fertilizer efficiency is low, and the garbage cannot be completely harmless, so it is not easy to be accepted by farmers

So far, my country still uses landfill as the main method of garbage disposal, but this method needs to occupy valuable land resources, and in developed large cities and coastal areas, there are too many people and less land, resulting in nowhere for urban garbage to be filled; Although composting technology has a long history of application in our country and can realize the recycling of compostable organic waste in garbage, but because our country uses mixed collection of garbage, it increases the difficulty of garbage composting, which leads to excessive cost and high quality. low, limited use
