An Activity-Based Method for Compiling Air Pollutant Emission Inventory in Port Area

Abstract

The invention discloses a method for compiling a port atmospheric pollutant discharge inventory based on activities. The method comprises a method for estimating discharge of port ships, a method for estimating discharge of harbour boats, a method for estimating discharge of port machines, a method for estimating discharge of heavy trucks, a method for estimating discharge of switch engines and a method for estimating the discharge amount of main transport locomotives. According to the method for compiling the port atmospheric pollutant discharge inventory based on activities provided by the invention, the port atmospheric pollutant discharge inventory is established based on port activities aiming at discharge sources, such as the port machines, the port ships, the harbour boats, the main transport locomotives and the switch engines; therefore, the source and pool relationship of a port and atmospheric pollutants in the inland navigation industry is known easily; the environmental situation of the shipping industry is correctly judged easily; and scientific basis is provided for setting reasonable policies and measures of a discharge reduction scheme in the shipping industry.

Description

technical field [0001] The invention relates to an activity-based method for compiling an air pollutant discharge list in a port area, and belongs to the technical field of environmental protection and air pollution prevention and control. Background technique [0002] With the rapid development of the economy, the emission of air pollutants is increasing day by day, and the environmental problems are becoming more and more serious. The prominent performance is that severe smog has occurred simultaneously in a large area in the central and eastern parts of China in recent years. Emissions from traffic sources have become an important factor triggering smog in many areas of my country, and the port area, which is an important part of the traffic system 2.5 Outside, PM 10 , DPM (diesel particulate matter), SO 2 , NO x etc. accounted for a significant proportion of the city's share rate. In 2010, only the air pollutant PM emitted by ships in Shanghai Port 10 , PM 2.5 , NO ...

AI Technical Summary

Problems solved by technology

The emission of air pollutants in the inland port area is due to the lack of seaward diffusion and transfer areas, coupled with the backwardness of port operating equipment and technology, especially the NO x The discharge is basically in an uncontrolled state, and its pollution is more serious, which directly affects the health of local people

[0003] At present, the most basic emission inventory for energy conservation and emission reduction in domestic port areas is still in the initial research stage, the emission inventory suitable for Chinese ports and ships has not yet been established, and the actual emission factors for Chinese ports and ships, especially inland ports and ships, have not yet been released

Secondly, it failed to organically combine the "top-down" and "bottom-up" air pollutant discharge monitoring methods to form a systematic air pollutant discharge monitoring system in the port area; the calculation of the port pollutant discharge is It is a very complicated issue, and limited by monitoring methods and monitoring forces, the current discharge of air pollutants in the port area is mainly estimated based on material balance formulas and empirical emission coefficients; affected by monitoring technologies and methods, the current port mechanical activities The means and technologies for real-time monitoring of the data are not yet mature, and are not widely used in port energy conservation and emission reduction work. At the same time, the statistical measurement system for energy consumption and emissions is not perfect, and the port does not have the ability to measure different vehicles and production equipment. It is impossible to obtain more accurate emission and energy consumption data, and it is not possible to take corresponding accurate calculations according to different working conditions of vehicles and equipment. Therefore, the refined emission of air pollutants from "bottom to top" Monitoring technology and its research have not yet been applied in the port area

In addition, there is no systematic statistics on the emission of conventional air pollutants other than carbon dioxide

Finally, the port area cannot obtain more accurate emission and energy consumption data, and the pertinence and purpose of emission control and the orientation of technological development are not clear, which has an impact on the refined management of the port area
