Problems solved by technology

[0004] The purpose of the present invention is to provide a method for treating, transforming and utilizing organic wastes, aiming at the disadvantages of the existing organic waste treatment technologies such as being unenvironmentally friendly and uneconomical, and to make up for the lack of fertilizers and high-quality protein feeds. The pretreated organic waste is processed by biological transabdominal transformation, and the cockroaches treated with organic waste can be used as protein feed for aquaculture, and the feces produced by it can be used as fertilizer

Embodiment 1

[0017] Collect domestic waste from residents, sort the domestic waste, remove metal products, glass ceramics, plastics and other substances, crush and stir, measure the water content is not more than 90%, and the particle size of solid particles is not more than 10 mesh, pass it through The conveying pipeline is transported to the feeding channel of the Periplaneta americana waste treatment room. The number of partitions per meter of the breeding rack in the treatment room is about 25, and the treatment room raises about 8 × 10 per square meter of Periplaneta americana. 4 Only, the temperature in the treatment room is controlled at 25°C to 32°C, and the humidity is controlled at 60% to 95%. On average, 4% of the domestic waste of residents treated and transformed by Periplaneta americana per day is achieved. Feed under this condition for 6 months, collect the Periplaneta americana in the treatment room, weigh after drying, and the treatment room area per square meter can get ab...

Embodiment 2

[0019] Collect agricultural and forestry organic waste, mainly rotten vegetables and fruits and straw leaves, etc., sort the agricultural and forestry organic waste, remove metal products, glass ceramics, plastics and other substances, crush and stir, and measure the water content to about 70%. The particle size of the solid matter is not more than 10 mesh, and it is transported to the feeding channel of the German cockroach treatment room through the conveyor belt. The breeding rack in the treatment room has about 90 partitions per meter, and the single layer of the treatment room is used to raise German cockroaches per square meter. Blattella about 2.5×10 6 Only, the temperature in the treatment room is controlled at 25°C to 32°C, and the humidity is controlled at 70% to 90%. The average amount of organic waste processed and transformed by German cockroaches per day is 10% of the total weight of German cockroaches in the treatment room. Feeding under these conditions After 3...

Embodiment 3

[0021] Collect industrial organic waste, mainly industrial waste such as distiller's grains and bean dregs, sort industrial organic waste, and remove materials such as metal products and glass that cannot be processed by the oriental cockroach and affect equipment crushing, and then carry out Grinding and stirring, measuring about 85% water content, solid particle size not greater than 10 mesh, transporting it to the feeding channel of the oriental cockroach treatment room by a trolley, the breeding rack in the treatment room, the number of partitions per meter is 50, 1.5 × 10 oriental cockroaches were raised per square meter in the treatment room. 5 Only the temperature of the treatment room is controlled at 22°C to 28°C, and the humidity is controlled at 60% to 85%. The average amount of industrial organic waste processed and transformed by the oriental cockroach per day is 12% of the total weight of the oriental cockroach in the treatment room. Feed under this condition for...

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a method for treating, transforming and utilizing organic waste. According to the method, the pre-treated organic waste is subjected to bio-abdominal transformation treatment through cockroaches, the cockroaches for treating the organic waste serve as protein feed for the cultivation industry, andmanure generated by the cockroaches serve as fertilizers. By adopting the method for treating, transforming and utilizing the organic waste, other energy sources are not consumed, secondary pollutionof three wastes of the waste water, the waste gas and the industrial residue is avoided in the treatment process, the treatment difficult problem of the organic waste is effectively solved, the transformation cost is low, benefits are high, and social benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for treating, transforming and utilizing organic waste. Background technique [0002] Organic waste refers to the general term of household garbage, agricultural and forestry organic waste, and industrial organic waste. The waste containing organic components in domestic garbage is mainly paper, fiber, bamboo, wood, and kitchen waste. More than 60% of domestic waste is organic waste, and it is increasing year by year, of which 40-60% is kitchen waste or meal leftovers. The treatment of organic waste has become a major social issue related to people's livelihood. [0003] At present, there are three main ways to deal with organic waste at home and abroad: landfill, incineration and biological treatment. As the final treatment method of organic waste, landfill is widely used. Although this method is simple and easy to handle and has a large pr...
