The emission rights trading management system solution uses modern information technology as a means, uses system engineering methods, and uses information technology to control the total amount of pollutants, maintain various calculation parameters, system user management, and emission rights according to the emission rights trading system. Specific functions such as initial allocation, on-site trading of emission rights, online monitoring of transaction information, and system security management are systematically designed and implemented. This solution adopts
structure and is built using a three-layer computing model of browser,
server and backend database server
,
This model is not only convenient for the program Development and maintenance, and changes in the backend database system or database structure will not have an impact on the client, which facilitates system maintenance and upgrades
,
In order to realize the function of the emission rights trading system on the Internet, advanced The technology supports interactive architecture, ensuring and maintaining the security and efficiency of public and personal information.

Design instructions for each functional module of the system
br/> System design principles
Transaction integrity
From the current level of application, actual needs and Design based on development trends, and design system functions in detail based on investigation and analysis of application requirements, data composition, and workflow to ensure the completeness of data and system functions and meet the needs of total pollutant control.
System Reliability
The system adopts strict security and confidentiality measures, such as multi-level protection measures for databases, files and users.
System openness
Adopting component design ideas and standardizing conceptual functions to make the interface universal, the system can flexibly switch between different databases.
Improve the ratio of successful transactions
The system can provide the optimal matching plan to promote successful transactions.
Overall system design
The system consists of a total pollutant control subsystem, a basic information management subsystem, an initial emission rights allocation subsystem, an online monitoring subsystem, and an emission rights trading subsystem. It consists of management subsystem and user rights management subsystem.

Total pollutant emission control The total pollutant amount control subsystem is mainly responsible for formulating the overall total amount control plan, such as Allowable emissions and reductions of each pollutant, optimization of allowable emissions and reductions, treatment measures, allocation of treatment investments, etc.
First, formulate a pollutant emission reduction plan. According to my country's situation, the total pollutant emission control plan should be divided into two levels, one is the five-year plan, and the other is the annual plan. The five-year plan is consistent with the national economic and social development plan. It mainly stipulates the reduction targets within five years and stipulates the content of the annual plan in principle. The annual plan is actually an implementation plan. For cities, the five-year plan should be approved by the local people's congress, and the annual plan can be approved by the local government. The planning time should be longer to provide long-term expectations to the sewage discharge units. For example, the United States' Acid Rain Plan stipulates ultimate goals for sulfur dioxide emissions.
The definition and collection of total pollutant data. Pollutant emission data refers to the emission parameters of artificial pollution sources that directly discharge pollutants into the environment, such as pollutant types, pollutant emission rates and concentrations, and emission patterns. , emission parameters (
Exhaust parameters, exhaust port position)
etc. The declaration and collection of pollutant emission data are generally based on legal entities.
Among the existing pollutant emission data, there are generally
categories according to the system of data actually used. One type is data formed according to the national unified number []
, referred to as statistical data
, which is the official data of pollutant emissions. The first category is data used by local environmental protection bureaus for sewage charges, referred to as charging data. The other category is pollutant discharge declaration data, referred to as declaration data, which is specifically data generated in accordance with the National Pollutant Discharge Declaration Registration Form formulated by the State Environmental Protection Administration.
