Abstract

The invention discloses a sewage deep-sea optimized discharge response relationship based on tidal current changes. By aiming at the best sewage dilution effect, the lowest energy consumption and the optimal sewage discharge efficiency, the flow velocity in the tidal change interval of the engineering sea area and the corresponding flow rate are established. The response relationship between the optimal sewage discharge, using this response relationship to optimize and adjust the sewage deep-sea discharge in real time, can make the sewage highly diluted in the smallest possible space-time range, so as to improve its initial dilution effect and finally meet the standard discharge, which can improve The management level of sewage deep-sea discharge, and the maintenance of the ecological quality level of the sea environment.

Description

technical field [0001] The invention relates to a sewage discharge method, in particular to a method for determining the response relationship of sewage deep-sea optimal discharge based on tidal current changes. Background technique [0002] In recent years, with the rapid development of my country's coastal economy, a series of major sea-related projects have been frequently constructed, and new sewage discharges will inevitably cause greater pressure on the ecological environment of the project sea area. With the help of waves, tides and currents, which have strong mixing and transport capabilities, the offshore deep-sea discharge of sewage has gradually become a priority engineering measure for sewage discharge in coastal areas due to its low engineering cost and operating costs. However, the current deep-sea discharge project fails to realize the real-time optimization and dynamic adjustment mechanism with the complex tidal wave movement, so the sewage entering the envir...
