Abstract

The invention discloses a sewage deep sea optimization discharge response relationship determining method based on tide change. The response relationship between flow speed in an engineering sea areatide change interval and optimal sewage discharge amount is established by taking optimal sewage diluting effects, the lowest energy consumption and optimal sewage discharge efficiency as goals, sewage deep sea discharge amount is optimized and adjusted in real time by the aid of the response relationship, sewage can be highly diluted within a space-time range as narrow as possible, initial diluting effects are improved, up-to-standard discharge is finally realized, the management level of sewage deep sea discharge can be improved, and the ecological quality level of a sea area environment ismaintained.

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...
