Wastewater diffuser, a deep-water diffuser for double-layer sewage discharge in rivers, consists of a discharge main pipe through a connecting pipe and two upper and lower diffuser pipes. The sewage enters the upper and lower diffuser pipes through the connecting pipe, and the sewage on the diffuser pipe The diversion pipe connected to the spout is discharged into the river to make full use of the effective depth of the river and increase the dilution ratio of sewage discharge.
The deep-water diffuser is arranged perpendicular to the direction of water flow. There are multiple sewage spouts on the upper and lower diffusers. Each nozzle is equipped with a diversion pipe, and the discharge main pipe and the upper and lower diffuser pipes are all fixed with support frames. Its shape is linear, L-shaped and Y-shaped.
