Greenhouse gas emission monitoring method of town household refuse disposal system

Abstract

The invention discloses a greenhouse gas emission monitoring method of a town household refuse disposal system. By monitoring methane gas and refuse components and revising the refuse components, degradable organic carbon content, proportion of methane in refuse landfill gases, a half-life period and the like, the greenhouse gas emission monitoring method puts forward selection principles of the parameters under different conditions selectively, performs connection on instruments on site and upper computer working stations and is capable of updating data in real time. The greenhouse gas emission monitoring method reduces monitoring cost, is stable in monitoring results and high in accounting accuracy.

Description

technical field [0001] The invention relates to the field of greenhouse gas emissions, in particular to a monitoring method for greenhouse gas emissions of an urban domestic garbage treatment system. Background technique [0002] Greenhouse gas (GHG) emissions during the processing of municipal solid waste such as domestic waste (MSW) are an important source of greenhouse gases. In order to formulate targeted greenhouse gas emission reduction strategies for household waste, domestic and foreign scholars have studied the greenhouse gas emission laws of different disposal methods such as landfill and incineration, and adopted the life cycle assessment method (LCA) and the Intergovernmental Panel on Climate Change of the United Nations respectively. (IPCC) recommended method, and the accounting method based on the Clean Development Mechanism (CDM), conduct accounting and analysis of greenhouse gas emissions for domestic waste treatment technology and the entire treatment system...

Problems solved by technology

However, the flux box disturbs the observation object, and there is a certain pressure difference and temperature difference inside and outside the box, which makes the test deviate from the actual situation.

The flux box method includes static box and dynamic box. The development from static box to dynamic box overcomes the above problems to a certain extent, but the dynamic box itself also has certain defects: on the one hand, the balanced flow rate of the dynamic box will interfere with the interface gas flow rate. Transmission, on the other hand, in the case of low gas discharge flux, the difference between the measured gas concentration at the outlet and inlet of the box is very small, so a high measurement accuracy is required, otherwise it will cause a large measurement error

[0007] The cost of the monitoring method in the prior art is high, the factors affected by the monitoring are complicated, the monitoring results are unstable, etc., and the accuracy of the accounting is affected
