A5 Deep Sea Discharge Pipe Project in Tieshangang Industrial Zone of Beihai

A5 deep-sea discharge pipe project is a key infrastructure project of Guangxi Zhuang Autonomous Region, and also an important support project for Beihai City to go to the sea and build a seaward economy. The discharge capacity of the project is designed according to the long-term sewage volume, and the discharge capacity is 600,000m3/d. A new deep-sea discharge pipe will be built from the 3# pressure regulating well (without pressure regulating well) to the A5 discharge port, and the total length of the pipeline will be about 16.1km (including the diffusion section), and the diameter of the pipe will be DN2700, and the pipe will be made of steel pipe with a wall thickness of 20mm; and the area of sea used for the pipeline will be 36.3836 hectares.

After the project is completed and put into operation, it will not only be able to solve the problem of final discharge of sewage from the four major areas of Beihai Tieshangang (Linhai) Industrial Zone, Tieshandong East Harbor Industrial Park, Yulin Longtan Industrial Park and Bainping Industrial Park after the sewage treatment is up to the standard, but also make full use of the environmental capacity of the ocean, and better protect the quality of the water environment of the land area and the water environment of the near-shore sea area.
