Abstract

The invention discloses a rotary composite biological sewage treatment device and a method. The device comprises a water inlet pipe, a sludge discharging passage, a water outlet pipe, aeration elements, material filling elements, a rotary bracket, a reaction tank and driving equipment, wherein the driving equipment is in driving connection with a center rotating shaft of the rotary bracket; the rotary bracket is mounted on the reaction tank by virtue of the rotating shaft, and is sequentially provided with the material filling elements and the aeration elements parallel to a horizontal plane by uniform distribution from an inner ring to an outer ring; and sewage enters the device from the water inlet pipe, sludge is discharged from the sludge discharging passage, and treated sewage is discharged from the water outlet pipe. The device merges advantages of two technologies namely a bio-film method and an activated sludge method, so that the device is good in treatment effect, strong in impact load resistance, high in economical efficiency, efficient and stable in running, small in floor area, and convenient in operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and is especially suitable for domestic sewage treatment in rural areas and small towns. Background technique [0002] The biofilm method is to use the film-like biological sludge attached to the filter material or some carriers to treat organic pollutants. Changes in water quality and quantity have the characteristics of good adaptability, ability to handle low-concentration sewage, simple operation and management, and low operating costs, but it is difficult to control the active biomass, poor operating flexibility, limited BOD volume load, low efficiency, complex operation and Corrosion and aging of filter material and other problems. [0003] The activated sludge method is an aerobic biological treatment method for sewage, which utilizes the bacterial micelles formed during the reproduction and growth of certain microorganisms to flocculate, adsorb and degrade organic pollutants in ...
