1. Combustion
Organic waste is oxidized to inert gases and inorganic non-combustible substances at high temperatures and sufficient oxygen to form a stable solid white residue. This treatment is the process of reducing resource consumption and waste generation by reducing production, distribution and consumption, and using appropriate measures to reduce the amount of waste, including volume and weight.
2, composting
Use of microorganisms in the waste, organic matter for biochemical reactions to produce a humus-like substance that can be used as fertilizer and soil improvement. This treatment method of recycling waste as raw materials for direct use or recycling waste, that is, take appropriate measures to achieve resource utilization in the process of waste.
Including reuse refers to waste as a product directly or after repair, refurbishment, remanufacturing continue as a product, or all or part of the use of waste as parts of other products.
3, recycling
Recyclable plastics, paper, metals, etc..
4, landfill method
Landfill disposal can be divided into sanitary landfill, compressed landfill and crushed landfill. In order to prevent secondary pollution, easy to landfill, landfill must meet the following requirements: no toxic and hazardous substances; landfill water content of less than 20% to 30%, inorganic components greater than 60%, density greater than 0.5t/m3. In areas of heavy rainfall, allowed to increase the water content of the landfill, but it is best not to impede the construction of the rolling.
5, biological transformation
Solid materials such as glass fragments, bones and fish bones are separated from the garbage by a water drum. Biodegradable materials are crushed and processed to be used as raw materials for solid fermented organic fertilizer. Washing and filtering wastewater should flow into the cement tank for treatment. Solid-liquid separator is used to treat the waste water from aeration and degreasing in the cement tank. Solid waste is used for fermentation to produce organic fertilizer. The separated wastewater is used for biogas fermentation.
