Problems solved by technology

Relying on ocean dynamics to deduce pollutant discharge parameters from offshore sampling parameters has no precedent in the ocean, but a similar method has been initially developed in air pollution monitoring, and it is completely feasible to extend it to the ocean

Embodiment Construction

[0008] 1. According to the ocean dynamics characteristics of the sea area near the sewage outlet, select an appropriate numerical model, give appropriate initial conditions, boundary conditions, etc., and adjust the parameters of the model, so that the transport and diffusion characteristics of the sea area near the sewage outlet can be simulated. It is more accurate to reflect the nature of the actual ocean. At this time, the model is considered to be accurate, and it will be used as the basis for the next step of inversion of pollutant discharge from land-based sewage outlets.

[0009] 2. Inversion of land-based pollutant discharge by using genetic algorithm:

[0010] a. Define an objective function;

[0011] b. Initialize the feasible solution population under certain constraints, each feasible solution is coded by a vector X, called a chromosome, and the component of the vector represents a gene, which corresponds to a certain decision variable of the feasible solution;

Abstract

The invention belongs to the field of land discharge capacity monitoring and managing technique, advancing an oceanic environment pollution monitoring method able to backward obtain the land discharge capacity by the pollutant concentration monitored through on-sea sampling, firstly establishing an offshore oceanic kinetics numerical mode, then introducing the genetic algorithm into the research on the oceanic environment problem, and establishing the backward relationship between on-sea sampling parameters and pollution discharging parameters by systemic research, design and training on the oceanic environment problem, thus obtaining the corresponding land discharge capacity by the pollutant concentration monitored by on-sea sampling. The invention has strong practicality and high universality and mainly applies to monitoring and managing the land discharge capacity.

Description

technical field [0001] The inversion method of pollutant discharge from land-based sources is obtained through the concentration of pollutants monitored by sea sampling and genetic algorithm. Background technique [0002] In marine environmental management and pollution control, obtaining data on land-based pollution sources is the core link. However, due to the difficulty in monitoring pollution sources from the sea, and the investigation of land-based pollution discharge itself is a process with considerable uncertainty and many other factors, resulting in the lack of data on land-based pollution discharge and low quality data, which greatly hinders marine environmental pollution. monitoring, governance and research. [0003] In view of this present situation, the present invention proposes this new monitoring method that the seawater near the sewage outlet is sampled and analyzed (hereinafter referred to as "sea sampling monitoring"), which has the following main advanta...
