Description

Rotary reactor for biomass garbage degradation

Technical Field

The utility model belongs to the technical field of the environmental protection, concretely relates to a rotary reactor for biomass garbage degradation.

Background

Biomass refers to various organic substances produced by photosynthesis of green plants, including organic substances derived from organisms such as microorganisms, plants and animals, and byproducts thereof, and biomass waste is biomass waste which is discarded without losing its original value. Biomass waste can be classified into three categories according to the source: (1) the urban biomass garbage mainly comprises household kitchen garbage, urban excrement, town sludge and the like; (2) crop wastes mainly comprising straws, dry branches and fallen leaves and the like; (3) animal dung. At present, the biomass garbage in China has the characteristics of large production amount, low treatment utilization rate and the like, is an important factor causing environmental and ecological problems, and especially in vast rural areas in China, a large amount of biomass garbage which cannot be effectively treated becomes one of the main pollution sources of the rural ecological environment.

The biomass waste is an important renewable resource and energy source while causing environmental pollution. Therefore, the biomass garbage is reasonably and efficiently utilized, the ecological environment can be improved, and the biomass energy which is renewable clean energy can be fully utilized. At present, the treatment technology of biomass garbage in China mainly comprises a landfill method, an incineration power generation method, a biodegradation method and the like. The landfill method requires large-area land occupation and simultaneously pollutes the underground water body. The incineration method is a municipal refuse treatment method which is more used, but the refuse incineration easily generates harmful substance dioxin, and the improper treatment can cause serious harm to the human health and the ecological environment. Due to the worry of people about secondary pollution of waste incineration, the site selection of a common incineration plant is very difficult, and the secondary pollution is often strongly resisted and objected by nearby residents. The biodegradation method utilizes the decomposition effect of microorganisms on the biomass garbage to carry out harmless treatment, and can produce feed or fertilizer while carrying out biodegradation on part of biomass garbage, so the application prospect is wide.
