Embodiment Construction

[0044] The purpose of the present invention is to propose a method for determining the limits of pollutant discharge permits considering the requirements of pollution reduction and aiming at the actual discharge rules of pollution sources, so as to support the management of pollutant discharge permits. In order to achieve the above purpose, the present invention proposes a method for determining the limit value of pollutant discharge permits for pollution sources based on technical standards, including the following:

[0045] Step 1. Collect and prepare data on the pollutant-discharging units, and determine the industry type of the pollutant-discharging units.

[0046] Among them, the data collected and prepared include at least basic data such as the industrial and commercial business license of the pollutant-discharging unit, environmental impact assessment report, pollution discharge monitoring data, environmental statistics data, pollutant discharge declaration and registra...

Abstract

The invention relates to a method for determining pollutant discharge permission limit values of a pollution source based on technical standards. The method comprises the following steps of: (1), collecting and preparing data of a pollutant discharge unit, and determining the industry type of the pollutant discharge unit; (2), collecting all kinds of standards corresponding to the industry type, which the pollutant discharge unit belongs to; (3), according to the collected standards, determining pollutant discharge permission supervision indexes, a maximum daily average concentration limit value C and a maximum daily discharge limit value L<day>; (4), calculating a long-term average discharge load limit value LTA, a maximum daily discharge load limit value MDL and a monthly average discharge load limit value AML of different pollutants in the various pollutant discharge permission supervision indexes, and calculating proportionality coefficients beta<MDL> and beta<AML> among the maximum daily discharge load limit value MDL, the monthly average discharge load limit value AML and the long-term average discharge load limit value LTA; and (5), according to the beta<MDL> and beta<AML> obtained by calculation and the maximum daily discharge limit value L<day>, obtaining a monthly discharge limit value L<month> and a yearly discharge limit value L<year> by calculation.

Description

technical field [0001] The invention belongs to the technical field of water environment protection and environmental management, and in particular relates to how a certain pollutant discharge unit determines the limit value of the pollutant discharge permit to provide support for the management of the pollutant discharge permit. Background technique [0002] The pollutant discharge permit is an important means of implementing the total amount control system, which can scientifically and rationally allocate the total amount control goals and reduction tasks to each pollutant discharge unit, so as to ensure that the total amount control system is truly implemented and sees actual results. The National Pollutants Discharge Elimination System (NPDES) of the United States stipulates that all industrial pollution sources must determine emission limits based on technical standards, mainly based on the emission limit guidelines for major industries promulgated by EPA . It has been...
