The rotary decanter is a periodic operation that completes water intake, reaction, sedimentation, drainage, and idle in a single main structure SBR reaction tank. It can achieve continuous water intake, intermittent drainage, alternating pressure oxygen and aerobic states, thereby achieving the treatment goals of nitrogen and phosphorus removal and water purification. The rotary decanter is a key equipment used in the SBR wastewater treatment process, mainly working during the drainage period. The rotary decanter can follow the changes in water level, while the rotary grille ensures continuous discharge of the supernatant and prevents secondary pollution caused by floating debris entering the supernatant.
The rotary decanter can be widely used for municipal sewage treatment and various industrial wastewater treatment such as papermaking, beer, leather making, food, chemical industry, etc.
