Anaerobic reactor for high-concentration organic wastewater

Abstract

The utility model relates to a high-concentration organic wastewater anaerobic reactor in the field of anaerobic reactors. The high-concentration organic wastewater anaerobic reactor comprises a barrel, the bottom end of the barrel is connected with a blow-off pipe, the top end of the barrel is connected with a drain pipe, the top is provided with an exhaust pipe and a return pipe, and a separator is arranged in the barrel. A flow guide pipe is arranged on the peripheral side of the outer wall of the water outlet pipe, a buoy is installed at the upper end of the water outlet pipe, and spiral blades are installed inside the water outlet pipe. The liquid inlet pipe is slidably sleeved with the water outlet pipe, and the upper corrugated ring makes contact with the protruding end of the lower corrugated ring. Liquid impacts the spiral blade to drive the water outlet pipe to rotate, and the flow guide pipe enhances the rotating effect, so that the liquid is fully contacted with sludge. Meanwhile, water flow impact and buoy buoyancy make corrugated rings in contact, the water outlet pipe drives the flow guide pipe to stir, and sludge reaction is further promoted. The reaction efficiency and quality are effectively improved through rotary spraying and up-down vibration of the water outlet pipe, and the sludge treatment requirement is met.
