Abstract

The invention relates to the technical field of the wastewater biological treatment, and in particular relates to a device for fast screening and culturing anaerobic ammonia oxidation (Anammox) microbial communities. The device comprises an anaerobic reactor, an inner pressure tube type ultrafiltration membrane, a water inlet controlling device, an automatic pH regulating device, an equilibrium reagent-supplementing device, a pneumatic pressure regulation device and an electronic control automatic thermostatic device, wherein the anaerobic reactor is arranged in the electronic control automatic thermostatic device and connected with the inner pressure tube type ultrafiltration membrane, the automatic pH regulating device, the equilibrium reagent-supplementing device, the water inlet controlling device and the pneumatic pressure regulation device respectively. Compared with the prior art, the device for fast screening and culturing Anammox microbial communities can provide an environment for the rapid proliferation of Anammox, thus shortening the doubling time and increasing the growth rate of Anammox.

Description

technical field [0001] The invention relates to the technical field of wastewater biological treatment, in particular to a device for rapidly screening and cultivating anaerobic ammonium oxidation microbial flora. Background technique [0002] In 1990, the Kluyver Biotechnology Laboratory of the Delft University of Technology in the Netherlands developed the anammox process, that is, under anaerobic conditions, microorganisms directly convert NH 4 + as an electron donor, with NO 2 - As the electron acceptor, the NH 4 + or NO 2 - convert to N 2 biological oxidation process. Since the anammox process is completed using autotrophic microorganisms, there is no need to add additional COD to support denitrification, which can save 100% of carbon sources compared with conventional denitrification processes. Moreover, if the ANAMMOX process is combined with a pre-nitrification process, the nitrification process only requires part of the NH 4 + Oxidation to NO 2 - -N, su...
