This utility model relates to a high-concentration
anaerobic reactor for organic
wastewater, comprising a cylindrical body with a drain
pipe connected to the bottom and a drainage
pipe connected to the top. The top is equipped with an
exhaust pipe and a return
pipe, and a separator is installed inside. An inlet pipe at the bottom of the cylindrical body connects to an outlet pipe, and a guide pipe is provided on the outer periphery of the outlet pipe. A float is installed at the upper end, and a
spiral blade is installed inside. The inlet pipe and outlet pipe are slidably fitted together, with the upper corrugated ring contacting the protruding ends of the lower corrugated ring. The liquid impacts the
spiral blade, causing the outlet pipe to rotate. The guide pipe's orientation enhances the rotation effect, ensuring full contact between the liquid and
sludge. Simultaneously, the
water flow impact and
buoyancy cause the corrugated ring to make intermittent contact, and the outlet pipe drives the guide pipe to stir, further promoting the
sludge reaction. This utility model effectively improves reaction efficiency and quality through the rotating spray and up-and-down vibration of the outlet pipe, meeting the requirements for
sludge treatment.
