Embodiment 2

[0044] Before the device of embodiment 1 is applied to the dye decolorization, it is necessary to carry out sludge acclimatization:

[0045] 1. Sludge domestication:

[0046] The anaerobic sludge that the present invention adopts is the anaerobic section sludge that Xiamen Sewage Treatment Plant gets, adopts to add co-substrate glucose and gradually improve the domestication method of anthraquinone dyestuff-reactive brilliant blue KN-R concentration gradient:

[0047] The formula of the culture medium for domesticating anaerobic sludge is as follows: 3.0g L -1 NaCl, 0.095gL -1 NH 4 Cl, 0.027gL - 1 K H 2 PO 4 , 1.5.0g L -1 NaHCO 3 , 1.55mg L -1 FeSO 4 , 4.95mg L -1 MnSO 4 , 0.71mg L -1 ZnSO 4 , 0.015mgL -1 CaCl 2 ·6H 2 O, 0.48 mg L -1 CuSO 4 ·5H 2 O, 0.1gL -1 CoCl 2 ·6H 2 O, 0.1 mg L -1 MgSO 4 ; And correspondingly add different concentrations of glucose and different concentrations of reactive brilliant blue KN-R (10mg / L ~ 50mg / L).

Abstract

Belonging to the technical field of sewage treatment, the invention discloses a device and method for promoting rapid anthraquinone dye decolorization based on microbial fuel cell technology. The method is based on the combination of anaerobic sludge decolorization and bioelectrochemical treatment technology, a two-chamber microbial fuel cell system is constructed, electrogenesis bacteria and anaerobic sludge with decolorization function are added to the positive electrode, also glucose is added as a co-substrate to coordinate decolorization of the anthraquinone dye reactive brilliant blue KN-R, at the same time a culture solution is added as the nutrient to ensure the anaerobic environment of the positive electrode, air is introduced to the negative electrode to serve as the electron acceptor of the system, and the positive electrode and negative electrode are externally connected to a resistor to compose a loop. The device and method for rapid decolorization of anthraquinone dye provided by the invention have good effect, and have the advantages of small floor area, wide application range, simple equipment, easy operation, good treatment effect, energy recovery and the like, andcan be wide applied to biological treatment of sewage in the printing and dyeing industry and recovery of part electric energy, thus having good economic and environmental protection benefits.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a device and method for rapidly promoting the decolorization of anthraquinone dyes based on microbial fuel cell technology. Background technique [0002] Printing and dyeing wastewater is the main body of textile industry wastewater, accounting for more than 80% of textile industry wastewater discharge. Printing and dyeing wastewater is the wastewater discharged from desizing, bleaching, dyeing, printing, finishing and other processes in the printing and dyeing process. It usually contains dyes, detergents, sulfides, solvents, heavy metals and inorganic salts. It has large water volume, deep color, Composition complex, serious environmental pollution and so on. It is an important topic in the field of environmental science and engineering how to reduce the energy consumption in the treatment process while achieving the standard discharge of printing and dyeing wastewate...
