Abstract

The invention discloses a denitrification biological turntable for denitrification of urban sewage. The denitrification biological turntable comprises a front cover, a denitrification cylinder and a back cover; the denitrification cylinder comprises a metal cylinder body, a front guard plate, a back guard plate and a biological turntable body; the biological turntable body comprises a metal rotating shaft, a plurality of metal blades and electrified metal hoops; the metal rotating shaft can rotate under the action of a driving device, and the metal blades are evenly arranged on the outer circumference surface of the metal rotating shaft in a radial shape; each metal blade is evenly provided with a plurality of metal mesh holes, and a biofilm is generated on each metal blade; the electrified metal hoops are arranged on the front end face and the rear end face of the biological turntable body, and is connected with each metal blade; and each electrified metal hoop is connected with external circuits. The denitrification biological turntable for denitrification of the urban sewage is simple in process, suitable for urban sewage with less carbon sources, good in treatment effect, low in energy consumption and operation cost, long in service life, and convenient to maintain.

Description

technical field [0001] The invention relates to a system for purifying urban polluted water, in particular to a denitrification biological turntable for denitrification of urban sewage. Background technique [0002] At present, biological methods and chemical precipitation methods are the main technologies for sewage denitrification. However, in the actual operation of these technologies, a large amount of sludge that is difficult to dispose of will be generated, and the conventional denitrification process needs to add carbon sources. The denitrification used Denitrifying bacteria are facultative heterotrophic bacteria, which need to provide organic matter as electron donors. At the same time, nitrate and nitrite in water are reduced to nitrogen as electron acceptors, so that nitrogen can be removed. [0003] Carbon sources that can be used by denitrifying bacteria are mainly divided into the following three categories: [0004] 1. Carbon source contained in raw sewage ...
