At the same time, due to the large number of sewage treatment plants, domestic waste and kitchen waste generation points in small and medium cities in China and their locations are scattered, or due to inconvenient transportation, their centralized treatment and disposal are limited.
For more than half of the small and medium-sized sewage treatment plants or other organic waste generation points, due to the small area of the plant area, scattered locations and low sludge production, and most of the existing aerobic fermentation equipment has batch and static fermentation modes, it cannot be realized. Continuous operation, complex equipment configuration and high cost, etc., the fermentation efficiency of existing tank-type fermentation and warehouse-type fermentation is low, resulting in a long fermentation period (generally 20-30 days), which makes it occupy a large area. It is difficult to implement in the treatment plant
Therefore, it still lacks a suitable organic waste treatment and disposal equipment such as sludge with high efficiency, small footprint, low infrastructure investment and low operating costs.

Embodiment 1
[0050] This embodiment provides a box-type aerobic fermentation equipment for organic waste, which can treat the dewatered sludge produced by the urban domestic sewage treatment plant, so that the treated sludge can meet the stabilization requirements.
[0051] Such as figure 1 As shown, the system includes: box body 1, insulation layer 2, partition plate 3, feed port 4, discharge valve plate 5, vent port 6, waste liquid port 7, drive motor 8, movable gear set 9, chain 10 , scraper 11, fan 12, main pipe 13, branch pipe 14, control valve 15, exhaust pipe 16, monitoring instrument 17, control unit 18;
[0052] in,
[0053] The box body 1 is a cuboid box body with an insulation layer 2 inside, and the side wall is equipped with a material inlet 4, a discharge valve plate 5, a vent port 6, and a waste liquid port 7; the partition 3 divides the box body 1 according to the function. Area and operation area; drive motor 8, fan 13, control valve 15, control unit 18, etc. are install...
Embodiment 2
[0063] This embodiment provides a box-type aerobic fermentation equipment for organic waste, which can process pretreated domestic waste so that the processed product meets the stabilization requirements.
[0064] The system structure and figure 1 Basically the same, the difference is that the form and height of the scraper 11, the model of the fan 12, the number of the branch pipe 14, the model of the waste gas pipe 16 and the waste liquid port 7 should be increased by one level, and the thickness of the insulation layer is not less than 100mm.
[0065] Utilize the above aerobic fermentation equipment to ferment the pretreated domestic waste, and the domestic waste is added to the front end of the aerobic fermentation equipment box 1 through the feed port 4, and aerobic fermentation is carried out in the fermentation area of the box body 1; the drive motor 8. With the cooperation of the movable gear set 9, the scraper 11 is dragged by the chain 10, and the materials continu...

Abstract
The invention discloses an aerobic fermentation device and method for organic waste, and belongs to the field of waste treatment. The aerobic fermentation device comprises a box body, a chained turning-throwing device, an air supply system and a monitoring system, wherein according to functions, the box body is divided by a partition plate into a fermentation zone and an operation zone; a heat preservation layer, a feeding port, a discharging valve plate, an exhaust vent and a waste liquid port are arranged in the box body; the chained turning-throwing device comprises a driving motor, a movable gear group, a chain and scraping plates; turning, throwing, feeding and discharging of a material in the box body can be achieved; the air supply system comprises a draught fan, a control valve, a main pipe, branch pipes and a waste gas pipe; the monitoring system comprises a monitoring instrument and a control unit; and the control unit is used for controlling material feeding and discharging, running of the air supply system and other processes by monitoring and analyzing data fed back by the monitoring instrument. By adoption of the aerobic fermentation device, continuous feeding, continuous discharging, uniform mixing of the material, air supply as required and the reduction of odor emission can be achieved; the fermentation efficiency is improved and the fermentation period is shortened; and eventually, harmless and recycling treatment of the organic waste can be achieved.
Description
technical field [0001] The invention relates to the field of organic waste treatment produced in cities, towns, etc., in particular to an aerobic organic waste treatment system for treating urban organic waste such as dewatered sludge, domestic waste, and kitchen waste in urban sewage treatment plants. Fermentation equipment and methods. Background technique [0002] Usually, with the improvement of residents' living standards and the acceleration of urbanization, cities and towns continue to produce a large amount of urban organic waste, including dewatered sludge from sewage treatment plants, domestic waste, kitchen waste, garden waste, agricultural waste etc., which have caused phenomena such as "garbage siege" and "sludge dumping in disorder". According to relevant data, my country produced 100 million tons of domestic waste (including 60 million tons of kitchen waste) and 30 million tons of dewatered sludge in 2010. These pollutants have a high content of organic matt...
