Description

Technical Field

[0001] The invention relates to the field of port environmental protection, and in particular to a quantitative evaluation method for the pollution prevention and control level of a dry bulk cargo port terminal. Background Art

[0002] Dry bulk cargo ports are important cargo transportation hubs, but the loading and unloading of dusty dry bulk cargoes such as coal, ore, and grain can easily cause air pollution (including but not limited to water pollution, noise pollution, and solid waste pollution), which seriously affects the ecological environment and health of residents around the ports. These pollution problems have increased the environmental pressure on dry bulk cargo ports, and the need for environmental protection has become more urgent.

[0003] Looking at existing research at home and abroad, the evaluation of the pollution prevention and control level of dry bulk port terminals has attracted widespread attention, but there are still the following problems that need to be solved: 1) Pollution prevention and control measures are scattered and the effects vary greatly. Although ports in various places have adopted prevention and control measures such as sprinkling water to reduce dust and wastewater treatment, the lack of unified evaluation standards and methods makes it difficult to compare and optimize the pollution prevention and control effects of different ports; 2) There is a lack of scientific and standardized evaluation methods. Most of the existing evaluations are qualitative analyses and lack a quantitative evaluation system; 3) Existing pollution prevention and control evaluation methods usually lack systematicity and comprehensiveness, and the monitoring methods and data collection are imperfect. It is impossible to scientifically quantify the actual effect of pollution prevention and control, and it is difficult to provide strong support for policy formulation and environmental management.

[0004] The technical comparison is as follows:

[0005] Technical comparison with patent CN103927461A "A method for calculating the dynamic composition of port and ship air pollutant emission inventories"

[0006] 1. Patent CN103927461A proposes a method for dynamically building an inventory of air pollutants from ports and ships, and calculates single and superimposed emission inventories of air pollutants through port and ship emission modules, providing data support for energy conservation and emission reduction programs. The quantitative evaluation method for the pollution prevention and control level of dry bulk port terminals proposed by us focuses on the comprehensive evaluation of multiple environmental factors such as port dust and exhaust gas prevention and control, port water pollution, solid waste prevention and control, and noise prevention and control. It uses 12 indicators for comprehensive quantitative evaluation, focusing on the quantitative evaluation of port pollution prevention and control levels and comparative analysis between different ports.

[0007] Second, patent CN103927461A focuses on the generation of emission inventories of air pollutants and energy conservation and emission reduction, while our method focuses more on the evaluation of the implementation effect of pollution prevention and control measures, covering a wide range of environmental factors, and proposes a highly operational quantitative evaluation scheme to support port environmental protection decision-making and comparative analysis.

[0008] Technical comparison with patent CN117388139A "A method for monitoring and early warning of dust pollution in dry bulk ports based on patrol robots"

[0009] 1. Patent CN117388139A proposed a dry bulk port dust pollution monitoring and risk warning method based on patrol robots, focusing on real-time monitoring of dust concentration and early warning through patrol robots, focusing on immediate monitoring and risk warning. Our method focuses on evaluating the overall pollution prevention and control level of dry bulk port terminals through a quantitative evaluation index system, focusing on the comprehensiveness of pollution prevention and control measures and long-term effect evaluation.

[0010] Second, patent CN117388139A emphasizes the construction of real-time monitoring and early warning systems, while our method systematically evaluates the pollution prevention and control effects by constructing a scientific evaluation index system to provide a basis for port environmental protection decision-making. The two differ in technical direction and application objectives.

[0011] Technical comparison with patent CN118378795A "A method for evaluating the pollution reduction and carbon reduction effect for ports and terminals"

[0012] 1. Patent CN118378795A focuses on the pollution reduction and carbon reduction effect evaluation of air purification equipment, and uses pollutant gas concentration data analysis technology to evaluate the purification effect in real time. The quantitative evaluation method for the pollution prevention and control level of dry bulk port terminals proposed by us covers the prevention and control effects of multiple pollution sources such as dust, water pollution, solid waste, and noise, providing a more comprehensive pollution prevention and control effect evaluation framework.

[0013] Second, patent CN118378795A mainly focuses on the single effect evaluation of purification equipment, while our method integrates the evaluation of various pollution prevention and control measures of the port to form a complete quantitative evaluation system, which can provide support for port environmental protection decision-making in many aspects.

[0014] Based on the above background, this paper proposes a quantitative evaluation method for the pollution prevention and control level of dry bulk cargo port terminals. By establishing a set of standardized evaluation index systems and a scientific quantitative analysis framework, combined with pollution source monitoring data, the pollution prevention and control level is objectively and comprehensively evaluated. This method will provide a basis for the optimization of environmental protection policies for dry bulk cargo port terminals and promote the realization of ports' goals in sustainable development and green development. Summary of the invention
