Embodiment 1

[0036]The frame straddling the sludge compost material; the crawler walking device installed on the left and right sides under the frame; the cab equipped with an air-conditioning system is connected to the frame, and the cab has a built-in multi-way control valve; it is used to rotate and complete throwing The working turning drum; placed on the turning drum, it is used for turning and stirring the rotating knife shaft of the sludge compost heap; the boom for suspending the turning drum; the drum hydraulic motor driving the turning drum; used to control the turning The deceleration device for the speed of the throwing drum; the hydraulic power device installed on the frame; the auxiliary device for automatic spraying of liquid bacteria can also be added as needed to accelerate the sludge aerobic composting and eliminate the odor during the sludge composting process.

[0037] mainly includes:

[0038] Racks straddling sludge composting material;

[0039] The crawler walking ...

specific Embodiment approach

[0054] Using the remaining sludge of urban sewage treatment plants as raw materials, organic compound fertilizers are made through aerobic composting technology, which not only provides bio-organic fertilizers for increasing the production of agriculture and forestry, but also supplements the serious shortage of my country's fertilizer industry, which has great potential economic benefits. At the same time, it solves the problem of "secondary pollution" caused by the increasingly serious increase of urban sewage sludge, and fundamentally solves the problem of the final outlet of sludge. The aerobic composting process can be applied not only in the field of sludge treatment, but also in other fields such as solid waste, kitchen waste, and domestic waste. In conjunction with the accompanying drawings, the specific implementation is as follows:

[0055] (1) Transport the remaining sludge from the sewage treatment plant to the composting workshop. Due to the high moisture content ...

Abstract

The invention relates to a self-propelled turning device for sludge compost and a treatment method and belongs to environmentally-friendly solid waste treatment. The method comprises that: a mixing step, an aerobic compost period, a thoroughly decomposing step, a processing and compost production step and an odor treatment step, wherein the mixing step aims to adjust the moisture and the carbon nitrogen rate of dewatered sludge, improve the loosening degree, increase a contact area with air and contributes to aerobic fermentation; in the aerobic compost period, the oxygen is supplied through forced ventilation, and organic matters in materials begin to ferment under the action of aerobes; the thoroughly composting step comprises that: the sludge subjected to compost fermentation is not thoroughly decomposed, and is required to continuously undergo a thoroughly decomposing and ageing stage, namely secondary fermentation; the processing and compost production step comprises that: the sludge compost is processed according to fertilizer use and market demand to serve as a product for sales so as to improve overall economic efficiency; and the odor treatment step comprises that: odor is generated in the process of aerobic compost and can be discharged after deodorization treatment. In recent years, solid wastes have become important environmental problems limiting urban development. The composting treatment is a way to utilize solid waste resources and is gradually taken into account at home and abroad.

Description

technical field [0001] The invention relates to a self-propelled turning and throwing device and treatment method for sludge composting, belonging to the field of environmental protection solid waste treatment. In recent years, solid waste has become an important environmental problem restricting urban development. Composting is a way of resource utilization of solid waste, which has been gradually paid attention to both at home and abroad. Background technique [0002] With the development of the domestic sewage treatment industry, the total amount and degree of sewage treatment will continue to increase, and the amount of sludge produced will also increase day by day. So far, the random dumping, stacking and landfilling of sludge have caused serious "secondary pollution". Therefore, the disposal of urban sludge has become a "bottleneck" that restricts the healthy development of my country's urban sewage treatment industry. Due to the different actual conditions in vario...
