Abstract

The invention provides a potential-energy biological sewage purifier. The potential-energy biological sewage purifier consists of a plurality of modified potential-energy reoxygenation biological rotating discs, wherein the plurality of modified potential-energy reoxygenation biological rotating discs are arranged in a spiral step shape; the sewage spirally flows through the plurality of modifiedpotential-energy reoxygenation biological rotating discs from top to bottom; and for the vertically adjacent modified potential-energy reoxygenation biological rotating discs, a third water outlet ofthe modified potential-energy reoxygenation biological rotating disc positioned at the upper part communicates with a second reoxygenation tank of the modified potential-energy reoxygenation biological rotating disc positioned at the lower part. According to the invention, sewage is allowed to intermittently pass through the modified potential-energy biological rotating disc for large-oxygen reoxygenation and air stripping through water head potential energy; and through treatment of the layer-by-layer modified potential-energy biological rotating disc, reoxygenation efficiency is high and energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a potential energy biological sewage purifier. Background technique [0002] With the acceleration of urbanization and industrialization in our country, more and more domestic sewage and industrial wastewater have caused serious pollution to the environment. At present, the deep biological treatment technology combining activated sludge and biological contact oxidation process is mainly used for sewage at home and abroad, so that the water quality after treatment can meet the standard of reuse water, but the aerobic process mostly adopts the method of blast aeration, The reoxygenation efficiency is low, the energy consumption is high, and the operation cost is high. Chinese patent 200520071365.X utilizes water potential energy to convert into kinetic energy through siphon for atmospheric reoxygenation and air blowing. Although it can reduce the ene...
