Evaluating and analyzing method for disposal of island organic wastes and application thereof

Abstract

The invention discloses an evaluating and analyzing method for disposal of island organic wastes and application thereof. The evaluating and analyzing method for disposal of the island organic wastes comprises the following steps: building an anaerobic digestion-pyrolysis gasification coupling organic waste disposal model; and calculating production capacity and energy consumption capacity by using the organic waste disposal model. Organic waste generation capacity on the island can be calculated through living conditions of island residues, combustible gas output and combustible gas production capacity can be calculated according to anaerobic digestion-pyrolysis gasification coupling model parameters, and the total energy consumption capacity is determined according to the anaerobic digestion-pyrolysis gasification coupling model, and thus, the flowing direction of energy on the island can be reasonably arranged, and the aims that the organic wastes on the island can be reasonably handled and fully utilized to produce energy can be fulfilled.

Description

technical field [0001] The invention relates to the field of organic waste treatment, in particular to an evaluation and analysis method for organic waste treatment on sea islands and its application. Background technique [0002] There are a large number of domestic islands, some of which are inhabited by residents, and the activities of the residents on the islands are relatively primitive, with little garbage and a single type. With the development of the economy, the islands have attracted more and more tourists to visit the islands with their unique environmental advantages. The amount of garbage on the Internet is increasing year by year, which directly leads to the inability of the original garbage disposal methods to adapt to the growth rate of existing garbage. [0003] The traditional waste disposal methods on islands include on-site landfill, incineration, and foreign transportation of waste. In-situ landfills are widely used on land, and the technology is mature...

AI Technical Summary

Problems solved by technology

In-situ landfills are widely used on land, and the technology is mature. However, due to the increase in tourists on the island, the service life of the landfill is significantly shortened, and the usable area on the island is limited, so it is not feasible to build a new garbage dump; After the garbage in the burial site has been harmlessly treated, there will still be potential safety hazards. The environment of the island is fragile and it is difficult to recover once it is damaged.

The incineration treatment method has a wide range of applications on land due to its good capacity reduction, high efficiency, and mature technology. However, due to the small area of ​​the island, the incineration plant is close to the residential area, and the dioxins produced by incineration are not easy to control. Negative impact

The external transportation of garbage reduces the environmental impact of garbage on the island, but there is a risk of secondary pollution because the garbage is in transit; the transportation cost of garbage transfer to outlying islands is high, which increases the economic pressure
