Up-flow anaerobic sludge blanket electrochemical sensor

Abstract

The invention discloses an up-flow anaerobic sludge blanket (UASB) electrochemical sensor and an operation method thereof, relates to an anaerobic wastewater treatment device and in particular relates to an up-flow anaerobic sludge blanket reactor device. The purpose of simply controlling and operating UASB can be achieved by real-time feedback of operation condition in the UASB device via MFC electrochemical signals due to the adoption of biological sensing function of a microbial fuel cell (MFC) on account of the defects of relative complex control and operation of the UASB. In addition, the defects of the prior art are overcome; the problems such as slow reaction time and inconvenient operation and maintenance and the like caused by the integration design defect of an integrated UASB-MFC biological sensing and coupling system can be solved; the UASB is simpler to start and debug in actual engineering operation; the great convenience is brought to the work of starting and operating the UASB.

Description

technical field [0001] The invention relates to an anaerobic wastewater treatment device, in particular to an upflow anaerobic sludge bed reactor device. technical background [0002] UASB reactor is the abbreviation of upflow anaerobic sludge bed reactor (upflowanaerobicsludgeblanketreactor). The reactor is an anaerobic biological treatment technology developed by Dutch professor Lettinga et al. It is a typical representative of a new generation of high-efficiency anaerobic reactors. In recent years, it has been used in the treatment of various organic sewage, and has been widely used in the treatment of industrial wastewater with high COD concentration, showing good treatment effect. However, because it still treats with anaerobic microorganisms as the core, UASB has strict requirements on environmental conditions, so it is difficult to cultivate and acclimatize, the start-up and commissioning period is long, it is sensitive to water quality and load changes, and its cont...

Problems solved by technology

However, the integrated UASB-MFC biosensor coupling system has a series of shortcomings caused by the design itself

For example, due to the long HRT brought by the integrated design, the sensing speed is not sensitive, the UASB reactor has to be stopped when the sensor has a problem and needs to be maintained, and the electricity-producing microorganisms are easily affected by the external hydraulic action in the reactor. needs further improvement in
