Embodiment 1

[0031] Collect food waste, sort the food waste, remove metal products, glass ceramics, plastics and other substances, crush and stir, roughly measure the water content of 65% to 80%, and the particle size of solids is less than 10 mesh. It is transported to the feeding channel of the Periplaneta americana breeding room through a pipeline. For every 100 square meters of breeding area, 25 tons of Periplaneta americana are raised, and an average of 1 ton of pretreated kitchen waste is processed every day. The temperature of the breeding room is controlled at 25-32°C. Celsius, humidity 65%-95%, regularly clean the collection pool under the cockroach breeding rack, sieve the ootheca and feces, and collect an average of 130 kg of feces per day. After mixing manure and straw, adjust the carbon-nitrogen ratio to 28:1, compost at a temperature of 50-55 degrees, and obtain organic fertilizer in 4 days.

Embodiment 2

[0033] Collect food waste, sort the food waste, remove metal products, glass ceramics, plastics and other substances, crush and stir, roughly measure the water content of 60% to 75%, and the particle size of solids is less than 10 mesh. It is transported to the feeding channel of the German cockroach breeding room through a conveyor belt. For every 100 square meters of breeding area, 12.5 tons of German cockroaches are raised, and an average of 1 ton of pretreated kitchen waste is processed every day. The temperature of the breeding room is controlled at 25 ° C ~ 32 ℃, the humidity is controlled at 70% to 90%, and an average of 80 kg of feces are collected every day. Store after drying as fertilizer raw material.

Embodiment 3

[0035] Collect food waste, sort food waste, remove materials such as metal products and glass that cannot be processed by cockroaches and affect equipment crushing in food waste, and carry out crushing and stirring. The water content is more than 90% according to rough measurement, and then add sawdust Wheat bran or grass leaves, etc., adjust the water content to 80% to 85%, and the solid particle size is less than 10 mesh, and transport it to the feeding channel of the oriental cockroach breeding room through pipelines. For each 100 square meters of breeding area, raise oriental cockroaches. 10 tons of cockroaches, an average of 1 ton of pretreated kitchen waste is processed every day. The temperature of the breeding room is controlled at 20°C-29°C, and the humidity is controlled at 60%-85%. An average of about 100kg of feces per day, mix the feces with straw, adjust the moisture to 50%-60%, and adjust the carbon-nitrogen ratio to 32:1. The composting temperature is 55 degree...

Abstract

The invention discloses an organic fertilizer and a preparation method thereof. Cockroaches are adopted for biological conversion treatment on kitchen wastes, and excrement generated when the kitchenwastes are treated by using the cockroaches can be used as an organic fertilizer. The organic fertilizer disclosed by the invention has the advantages of being good in dryness, free of smell, small insize and easy to store, meanwhile is high in nitrogen phosphorus and potassium content, rich in trace element, low in heavy metal content and is an ideal organic fertilizer. By adopting the preparation method, a great amount of high-quality cheap fertilizers can be produced, the kitchen wastes are ecologically treated, and not only are problems of social environment sanitation caused by the kitchen wastes and human health influence caused by the social environment sanitation solved, but also great economic benefits can be made.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, and relates to the use of cockroaches to carry out biotransformation treatment on pretreated kitchen wastes, and the feces produced by the cockroaches can be used as organic fertilizers while processing the kitchen wastes. Background technique [0002] High-quality organic fertilizer contains a variety of beneficial microorganisms, which can continuously release the nutrients needed for plant growth and a variety of plant growth stimulants. In addition to the three major elements of nitrogen, phosphorus, and potassium, fertilizers also contain medium and trace elements such as calcium, magnesium, sulfur, silicon, manganese, zinc, and boron. It has a high content of organic matter, which can increase the soil aggregate structure, improve soil fertility, water retention, and heat preservation capabilities, reduce pests and diseases, reduce the use of pesticides and chemical fertilizer...
