Embodiment 1

[0028] 1) Collect the biochemical sludge or poultry manure into the collection container, and transport the biochemical sludge or poultry manure to the earthworm bed ton bags through the screw conveyor at the bottom of the collection container. Add 200 grams of brown sugar, 1000 grams of EM bacteria and 100 grams of urea to the sludge or poultry manure, and the raw materials are transported by a screw conveyor and stirred evenly; the size of the collection container can be adjusted according to the size of the site, and the collection container is preferably A drum with a height of 10 meters and a diameter of 2 meters, and a 4-meter-long screw conveyor (commonly known as an auger) at the bottom of the drum. Livestock manure can be cow manure, pig manure and other livestock and poultry manure; biochemical sludge is biochemical sludge produced after biochemical treatment in paper mills and sewage treatment plants.

Abstract

A method for treating biochemical sludge or poultry and livestock manure by using earthworm belongs to the technical field of earthworm reaction. The method comprises the steps of collecting biochemical sludge or poultry and livestock manure, and adding brown sugar, effective microorganisms (EM) and urea into the biochemical sludge or poultry and livestock manure; transporting the treated biochemical sludge or poultry and livestock manure from the first step to earthworm bed ton bags, and arranging the earthworm bed ton bags on the floor; putting earthworm fry including artificially-fed earthworms and wild earthworms in the earthworm bed ton bags; holding the temperature and humidity of the earthworm bed ton bags; separating the earthworms from the manure treated by using the earthworms; and using the treated manure for planting lawn, sward and raising matrix and greening landscape. The treated manure by the invention meets the standard of organic fertilizer by detection in center for quality supervision and test of fertilizer under the ministry of agriculture.

Description

technical field [0001] The invention belongs to the technical field of earthworm reaction, and in particular relates to a method for treating biochemical sludge or poultry manure with earthworms. Background technique [0002] At present, the biochemical sludge produced by papermaking urban sewage plants and paper mills after biochemical treatment in cities has become a new source of pollution. This kind of biochemical sludge has the following hazards: ①Pathogen pollution: Since the sludge contains a large amount of organic matter, it is easy to decompose and rot, bringing a strong stench, accompanied by a large number of pathogens (pathogenic microorganisms and parasites). According to detection, there are thousands of pathogens in fresh sludge. If these sludges are stacked arbitrarily, they will pollute the water body and soil, lead to food chain infection, and eventually bring harm to human health; ②Excessive salt pollution: due to the existence of a considerable amount o...
