Abstract

The invention discloses a moving bed biofilm reactor and its sewage treatment method. The biofilm reactor comprises a tank body, an inlet water barrel, a peristaltic pump, an aeration sand head and an air aeration machine, the tank body is filled with a filler, the filler is a K3 filler, the diameter and the height of the K3 filler are 2.5cm and 1.1cm respectively, the material of the K3 filler is polypropylene, the filling rate of the filler in the tank body is 40%, and the reactor also comprises a time controller in order to control the on / off and the running time of the peristaltic pump, the air aeration machine and a water outlet solenoid valve. Compared with the prior art, the sewage treatment method disclosed in the invention has the advantages of realization of aerobic and anoxic environment in a same reactor, realization of a synchronous nitrification and denitrification process in a single reactor, organic load and aeration rate reduction, capital construction and operation cost reduction, and reaching of a good nitrogen removal effect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a moving bed biofilm reactor and a method for treating sewage. Background technique [0002] According to the traditional biological denitrification theory, the biological denitrification process includes assimilation, ammonification, nitrification and denitrification. First, through the ammonification of heterotrophic bacteria, organic nitrogen such as protein, urea, and amine compounds are converted into ammonia nitrogen, and then under aerobic conditions, through the action of aerobic autotrophic nitrifying bacteria and nitrosifying bacteria, the nitrogen in sewage Ammonia nitrogen is oxidized to nitrite nitrogen or nitrate nitrogen. Finally, under anoxic conditions, denitrifying bacteria convert nitrite and nitrate into nitrogen gas, thereby achieving the purpose of denitrification. [0003] The traditional biological denitrification theory holds that under aerobic conditions...
