Dilution Diffusion Model Research of Offshore Deep-sea Discharge in Coastal Area

The sewage diffusion effect under deep water was carried out between different diffuser design parameters based on the hydraulic model test. According to test of length, riser spacing, number, nozzle horizontal azimuth angle and jet angle, specific need be determined comprehensively considering surface field, degree, project cost, etc. We used a coastal marine disposal in China as an example. article analyzes influence technology dilution condition large depth, puts forward engineering schemes length.
