The invention discloses a device for treating industrial wastewater difficult to biodegrade by virtue of an ABR-bioelectric Fenton coupling technique. The ABR is in a grid structure and a reactor is divided into a plurality of serial grid chambers by virtue of baffle plates, wherein one of the grid chambers is an anode chamber of a bioelectric Fenton system, the grid chamber which is adjacent to the anode chamber is a cathode chamber, and the anode and cathode chambers are separated by a proton membrane; a first water inlet is formed at the bottom end at the front end of the ABR, the top of the ABR is communicated with a gas collecting device, a water outlet is formed on the upper part of the anode chamber, and a second water inlet is formed in the cathode chamber; the anode chamber is internally provided with a carbon anode and the cathode chamber is internally provided with a ferric carbon cathode, and the carbon anode and the ferric carbon cathode are cografted and loaded. The device fully utilizes the grid structure of the ABR, so that the ABR is combined with MFC and the MFC is combined with Fenton, and the device is simple in structure, low in wastewater treatment cost and good in stability. Therefore, organic pollutants in wastewater are efficiently removed, accumulation of volatile acids in the ABR can be reduced, and the device can be used for generating biogas, and also can be used for generating electric energy, so that the wastewater is recycled in an environment-friendly manner.
Description
technical field [0001] The invention relates to an industrial wastewater treatment technology, in particular to a device for treating difficult biodegradable industrial wastewater by utilizing ABR (Anaerobic Baffled Reactor, anaerobic baffled reactor, ABR for short)-bioelectricity Fenton coupling technology. Background technique [0002] Anaerobic biological treatment has the advantages of low consumption and high efficiency. It organically combines pollutant removal with production capacity, and has good environmental and social economic benefits. Therefore, the use of anaerobic biological technology to treat high-concentration organic industrial wastewater has become a current research Hotspots, anaerobic reactors have been widely used in the treatment of easily biodegradable industrial wastewater such as sugar, beer, and citric acid. However, when the wastewater contains polymer pollutants or toxic substances that are difficult to biodegrade, such as printing and dyeing w...
