Problems solved by technology
[0004] The above methods partially solve the problem of composting a large amount of organic waste, but there are still problems that cannot be adapted to the continuous treatment of a particularly large amount of urban organic waste composting, and minimize manual intervention, so that operators can avoid being in a harsh working environment and protect the health of workers

Embodiment Construction
[0021] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0022] Such as figure 1 A method for resourceful treatment of organic waste of the present invention mainly includes batching, transportation, composting, aging and temperature control, ventilation, fertilizer processing and odor treatment processes, the steps of which are:
[0023] - Ingredients: send the pretreated dung, organic auxiliary materials and aerobic bacteria into the mixing mixer 1 and mix evenly. The organic auxiliary materials can be crushed crop straws, branches and leaves produced by forestry, etc. The moisture content of the organic auxiliary materials 85%, mixing speed of mixing mixer 1 is 6r / min-10r / min, and the evenly stirred mixture maintains a moisture content of 50%-65%;
[0024] - Conveying: The mixed material is conveyed to the compost bin by the screw conveyor 2, the outlet of the mixing mixer 1 is conn...

The invention provides a method for carrying out recycling treatment on organic wastes and relates to the technical field of a recycling utilization method of wastes containing organic matters including excrement dreg, kitchen wastes, sludge, crops residues and the like. The method mainly comprises the procedures of preparing materials, conveying, composting, curing, controlling the temperature, ventilating, machining a finished fertilizer and carrying out ozone treatment; a mixed material in a composting cabin is turned for 1-2 times each day by using a turning machine; the material is turned uniformly and then the mixed material is pushed into the discharging end of the composting cabin; the material is fed from on end of the composting cabin and is discharged from the other end, so as to realize continuous work; a deodorization system is composed of an organic glass cover, a deodorization air pipe, a deodorization tower, a deodorization fan and a chimney; the top of the composting cabin is tightly covered by the organic glass cover and gas generated in a composting process is introduced into the deodorization tower through the deodorization air pipe at the top of the composting cabin to be purified under a negative-pressure effect of the fan; and the purified gas is discharged to the atmosphere from the chimney.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for converting organic wastes such as dung residues and kitchen wastes into organic fertilizers to realize resource utilization of organic wastes. Background technique [0002] Organic waste such as dung, kitchen waste, and excess sludge has always been a problem for people as environmental pollutants. People often ignore that organic waste such as dung, kitchen waste, and excess sludge contains rich organic matter and crop growth. Elements such as nitrogen, phosphorus, and potassium needed for growth can become compost materials that are beneficial to agricultural production. The production of agricultural products with compost not only has good quality, but also can continuously improve the soil structure, and can also digest a large amount of organic waste that may cause environmental pollution. The composting method of the traditional farmhouse cove...
