Deep mine biological reaction device for wastewater aerobic biological treatment

The invention provides a deep mine biological reaction device for wastewater aerobic biological treatment, and relates to the technical field of wastewater treatment. The technical problem to be solved is to improve the wastewater treatment efficiency. The device comprises a wastewater treatment well, an outer pipe, an inner pipe, a water tank and an outflow pipe; the outer pipe is inserted in the wastewater treatment well, the inner pipe is coaxially fixed in the outer pipe, an upper flow chamber is formed in the space between the outer pipe and the inner pipe, a lower flow chamber is formed in the pipe cavity of the lower pipe, an aerator pipe is arranged at the bottom of the upper flow chamber, and the top end pipe orifices of the outer pipe and the inner pipe are connected to the water tank; a plurality of helical turbulent channels are arranged in the inner pipe to form a turbulent member, and a plurality of flashboards for controlling the flow rate of water are arranged above the turbulent member; a plurality of aerator pipes are respectively arranged at the upper and lower sides of the turbulent member; and the outflow pipe is inserted in the inner pipe, and the upper and lower ends of the outflow pipe respectively stretch out from the inner pipe. The device provided by the invention is suitable for aerobic biological treatment of wastewater.
