Embodiment 2

[0057] The multi-stage combined sewage treatment reactor of the present invention is used to treat dairy waste water. After the dairy waste water is processed by the grid-grease trap-primary sedimentation tank-air flotation tank process, it directly enters the combined microbial dual-source electrochemical sewage of the present invention. processor. Its influent COD cr The concentration is about 1000mg / L, BOD 5 The concentration is 300mg / L, the concentration of ammonia nitrogen is 75mg / L, and the relevant effluent COD after treatment cr The concentration is about 90mg / L, BOD 5 The concentration is about 40mg / L, and the concentration of ammonia nitrogen is about 10mg / L, which meets the first-level discharge standard of dairy wastewater in the "Integrated Wastewater Discharge Standard" (GB8978-1996). The hydraulic retention time of the reaction device is 8h, and the membrane flux is 30L / m 2 h.

Embodiment 3

[0059] The multi-stage combined sewage treatment reactor of the present invention is used for the treatment and reuse of sewage in tourist attractions. After the waste water is processed by the grid-grease trap-primary sedimentation tank-air flotation tank, it directly enters the combined microbial dual-stage reactor of the present invention. Source electrochemical sewage treatment, scenic spot sewage influent COD cr The concentration is 150-350mg / L, BOD 5 The concentration is 70-150mg / L, the total phosphorus concentration is 2-5mg / L, and the total nitrogen concentration is 10-40mg / L. After the grid treatment, it enters the regulating pool to adjust the water quality and quantity. After the treatment, the relevant effluent COD cr The concentration is 15mg / L, BOD 5 The concentration is 10mg / L, the total phosphorus concentration is 0.3mg / L, and the total nitrogen concentration is about 10mg / L, meeting the discharge requirements of "Urban Wastewater Recycling and Utilization of ...

Abstract

The invention provides a movable little-aerated combined bioreactor for denitrifying and dephosphorizing low-C / N urban sewage by coupling microbial fuel cells (MFC) and microbial fuel electrolytic cells (MEC) and a sewage treatment method of the combined bioreactor. The combined microbial double-source electrochemical sewage treatment device is characterized by comprising a combined multilevel biological reaction tank, two groups of coupled biological treatment system formed by connecting two power supplies formed by three groups of MFC and three groups of MEC by means of conducting wires and a diode by virtue of a specific method, and a PLC automatic control system.

Description

technical field [0001] The invention relates to a combined microbial dual-source electrochemical sewage reactor and a method for treating low C / N urban sewage by using the combined microbial dual-source electrochemical sewage reactor. Background technique [0002] Microbial Fuel Cell (MFC) is a device that uses microorganisms to directly convert chemical energy in organic matter into electrical energy. The basic working principle is: in the anaerobic environment of the anode chamber, the organic matter decomposes under the action of microorganisms and releases electrons and protons. Transfer to the cathode to form a current, and the protons are transferred to the cathode through the proton exchange membrane, and the oxidant gets electrons at the cathode and is reduced and combined with protons to form water. [0003] Microbial electrolysis cell (MEC) uses electrochemical technology to convert the chemical energy of organic matter in wastewater into hydrogen energy under the...
