Problems solved by technology

[0003] At the same time, in the rural suburbs, the feces produced by the farms are basically not treated, which will cause secondary pollution to the environment, so the feces produced by the farms have also become a new source of pollution

Embodiment 1

[0028] 1) Collect the biochemical sludge or livestock manure into the collection container, and transport the biochemical sludge or livestock manure to the earthworm bed ton bag through the screw conveyor set 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 livestock manure. The raw materials are transported by a screw conveyor and mixed evenly; the size of the collection container can be adjusted according to the size of the site. The collection container is preferably A drum with a height of 10 meters and a diameter of 2 meters has a 4-meter-long screw conveyor (commonly known as auger) at the bottom of the drum. Poultry manure can be cow manure, pig manure and other livestock and poultry manure; biochemical sludge is the biochemical sludge produced by paper mills and sewage treatment plants after biochemical treatment.

[0029] 2) After step 1), the treated biochemical sludge or livestock...

Embodiment 2

[0036] 1) Collect the biochemical sludge or livestock manure into the collection container, and transport the biochemical sludge or livestock manure to the earthworm bed ton bag through the screw conveyor set at the bottom of the collection container. 100 grams of brown sugar, 500 grams of EM bacteria and 50 grams of urea are added to the sludge or livestock manure, and the raw materials are conveyed by a screw conveyor and mixed evenly. Poultry manure can be cow manure, pig manure and other livestock and poultry manure; biochemical sludge is the biochemical sludge produced by paper mills and sewage treatment plants after biochemical treatment.

[0037] 2) After step 1), the treated biochemical sludge or livestock manure is transported to earthworm bed ton bags, and each earthworm bed ton bag is filled with 0.6 tons of biochemical sludge or livestock manure, and then the earthworm bed ton bags are arranged Place 500 bags per acre on the site.

[0038] 3) Put 5,000 earthworm seedli...

Embodiment 3

[0044] 1) Collect the biochemical sludge or livestock manure into the collection container, and transport the biochemical sludge or livestock manure to the earthworm bed ton bag through the screw conveyor set at the bottom of the collection container. 300 grams of brown sugar, 1500 grams of EM bacteria, and 150 grams of urea are added to the sludge or livestock manure, and the raw materials are conveyed by a screw conveyor and mixed evenly. Poultry manure can be cow manure, pig manure and other livestock and poultry manure; biochemical sludge is the biochemical sludge produced by paper mills and sewage treatment plants after biochemical treatment.

[0045] 2) After step 1), the treated biochemical sludge or livestock manure is transported to earthworm bed ton bags. Each earthworm bed ton bag contains 1 ton of biochemical sludge or livestock manure, and then the earthworm bed tons are arranged On the site, 400 bags are placed per acre.

[0046] 3) Put 10,000 earthworm seedlings in ...

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 specifically relates to a method for treating biochemical sludge with earthworms. Background technique [0002] At present, the biochemical sludge produced by the biochemical treatment of paper-making municipal sewage plants and paper mills in cities has become a new source of pollution. This kind of biochemical sludge has the following hazards: ① Pathogen pollution: Because the sludge contains a large amount of organic matter, it is easy to decompose and rot, bringing a strong odor and accompanying a large number of pathogens (pathogenic microorganisms and parasites). According to testing, there are thousands of pathogens in the fresh sludge. If these sludges are stacked arbitrarily, they will contaminate water bodies and soil, cause food chain infections, and ultimately bring harm to human health; ②Excessive salt pollution: due to the presence of a considerable amount of inorganic su...
