Array interconnection type electrode UASB reactor group

Abstract

The invention discloses an array interconnection type electrode UASB reactor group, and belongs to the technical field of sewage treatment. The reactor group comprises a cubic pool, six UASB reactor units are arranged in the cubic pool, the six UASB reactor units are arranged in a 2 * 3 arrangement mode, every two adjacent UASB reactor units are communicated through a pipeline, and a proton membrane is arranged in each pipeline; and an anode or a cathode is arranged in one UASB reactor unit, cathodes or anodes are correspondingly arranged in the other UASB reactor unit, two UASB reactor units or three UASB reactor units, the anodes and the cathodes are connected through wires, and the mutually communicated UASB reactor units are combined with the electrodes to form a bioelectrochemical system. The electrochemical reactor and the UASB reactor are combined, the advantages of the electrochemical reactor and the UASB reactor are effectively integrated, efficient synchronous starting of the laboratory multi-working-condition complex operation reactor is achieved, and further deep research is promoted.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an array interconnected electrode UASB reactor group. Background technique [0002] Anaerobic ammonium oxidation denitrification is currently one of the most shortcut denitrification methods, but there are nitrates (NO 3 - ) accumulation problem, and finally directly lead to the problem of low total nitrogen removal rate (<60%). Generally, the mixed sewage composed of domestic sewage and industrial wastewater is treated by short-range nitrification-anammox method, and about half of the NH 4 + Short-cut nitrification to produce NO 2 - , while removing COD, and then the remaining NH 4 + with NO 2 - Denitrification by anaerobic ammonium oxidation. After the mixed sewage is aerated, there is a certain amount of dissolved oxygen, COD and accumulated NO 3 - , will affect the anammox reaction and lead to a decrease in the overall denitrification efficiency of the...

AI Technical Summary

Problems solved by technology

[0005] The UASB reactor has the characteristics of high processing load, good water effluent effect, and low operating cost. However, due to the problems of slow start-up of the reactor, long culture time of bacteria, and long reaction time, it is difficult to realize one-time synchronous start-up of reactors under different working conditions. and research, usually starting a reactor and changing reactor operating conditions for follow-up research
