Abstract

The invention provides a biological filler stirring process based on an anaerobic / anoxic tank. The anaerobic / anoxic tank comprises a tank body for holding sewage, wherein a suspended filler is dispersed in the water body area of the tank body, the anaerobic / anoxic tank is further provided with a stirrer for stirring the suspended filler and a supporting member for fixing the stirrer, the supporting member is fixedly connected to the tank body, the stirrer comprises a motor fixed on the supporting member, a rotating shaft rotatably connected to the motor and extending to the water body area ina direction perpendicular to the liquid level, and a stirring paddle fixedly connected to the rotating shaft, the stirring paddle is arranged in the water body area, the anaerobic / anoxic tank furthercomprises a flow guiding cylinder with a pipe diameter direction parallel to the rotating shaft, the stirring paddle is arranged in the flow guiding cylinder, the flow guiding cylinder is fixedly connected to the tank body through brackets, and the condition of the biological filler stirring process is that stirring blades rotate anticlockwise.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a biological filler stirring process based on anaerobic / anoxic tanks. Background technique [0002] The Moving Bed Biofilm Reactor (MBBR) process is a new and efficient sewage treatment method. The MBBR relies on the aeration in the aeration tank and the lifting effect of the water flow to make the carrier in a fluidized state, thereby forming a suspended growth. Activated sludge and attached biofilm give full play to the advantages of both attached phase and suspended phase organisms. Different from the traditional biofilm method, the MBBR process combines the characteristics of the activated sludge method, and uses the entire reaction tank as the growth space for microorganisms, which greatly improves the space utilization rate; at the same time, the MBBR process combines the characteristics of the biofilm method and does not require Sludge backflow. The ...
