A device and method for treating and drying mixed substrates with earthworms

Abstract

The invention discloses an apparatus for processing mixed-substrate by earthworm and drying the mixed-substrate as well as a method thereof. According to the invention, fire coal slag, activated sludge, agricultural organic waste, life and processed kitchen rubbish matrix are stirred in proportion to obtain the mixed-substrate suitable for earthworm growth and breeding, the materials are uniformly spread on a slope processing bed for compost, then the earthworm is placed in the processed mixed-substrate, strong growth and breeding capability of the earthworm can be used, so that the mixed-substrate has the biological characteristic of the earthworm manure discharged by a granular shape, the mixed-substrate is processed to bio-fertilizer mud, and the subsequent slope drying bed is used for drying treatment, and the bio-fertilizer mud according with an organic fertilizer standard is obtained. The harmlessness recovery utilization of fire coal slag, activated sludge, agricultural organic waste and the kitchen garbage can be realized, harmful performance on human and environment are reduced with maximum degree, and high efficiency utilization of the resource is reached; at the same time, the apparatus and the method have the advantages of low enforcement cost and high efficiency.

Description

technical field [0001] The invention relates to a device and method for treating and drying mixed substrates with earthworms, and belongs to the technical field of waste biological treatment and reuse. Background technique [0002] Earthworm is a common terrestrial annelid with strong reproductive ability. It lives in the soil and often drills holes in the ground to loosen the soil. It feeds on decomposed organic matter debris and swallows them together with the soil. It also eats the stems and leaves of plants. It has the function of swallowing organic matter and discharging it in granular form. At the same time, the synergistic effect of earthworms and microorganisms can accelerate the decomposition process of organic matter, promote the cycle of carbon and nitrogen, and improve soil fertility. [0003] With the progress of society and the development of industry and agriculture, coal slag, activated sludge, agricultural organic waste, domestic and kitchen waste have beco...

Problems solved by technology

At present, there are mainly two ways to deal with them: one is to use centralized landfilling, which not only occupies a large amount of land due to the establishment of garbage landfills, but also produces harmful substances that pollute the air, soil, surface water and groundwater. At the same time, it is also easy to breed mosquitoes, pathogenic microorganisms, etc., which endanger human health; the second is to use incineration. Although this method can reduce the amount of garbage and save land, it can eliminate various pathogens and convert many toxic and harmful substances into non-toxic Harmful substances, but there are also many disadvantages, such as air pollution caused by exhaust gas, and harmful gases generated by incomplete combustion that endanger human health

These two treatment methods do not classify and recycle garbage, turn waste into treasure, and also cause environmental pollution and endanger human health
