Deposition-type phycomycetes biological electrochemical apparatus

Abstract

The invention discloses a deposition-type phycomycetes biological electrochemical apparatus. The deposition-type phycomycetes biological electrochemical apparatus comprises a sediment buried anode arranged in water sediment and a water-phase floating organism membrane; an electrochemical active organism membrane is adhered on the surface of the sediment buried anode, and a phycomycetes organism membrane is adhered onto the surface of the water-phase floating organism cathode; a capacitor capable of charging and discharging is arranged between the sediment buried anode and the water-phase floating organism cathode; with light, algae in the phycomycetes organism membrane generates oxygen under the photosynthesis, the cathode potential is increased, the electrochemical active organism membrane on the surface of the sediment buried anode is driven to oxidize and degrade HOPs in the water sediment and to charge the capacitor; and without light, the phycomycetes organism membrane does not perform the photosynthesis, the potential of the cathode is decreased, the capacitor discharges, and the electrochemical active organism membrane on the surface of the sediment buried anode is continuously driven to oxidize and degrade the HOPs in the water sediment. The apparatus can realize the all-weather continuous reinforced degradation of HOPs in the water sediment.

Description

technical field [0001] The invention relates to the technical field of bioelectrochemistry and environmental engineering, in particular to a sedimentary algae bioelectrochemical device. Background technique [0002] With the acceleration of industrialization and urbanization, a large number of artificially synthesized toxic organic compounds have entered the environmental water body, seriously endangering the ecosystem and threatening human health. Among them, the vast majority of hydrophobic organic pollutants (HOPs) with mobility, biotoxicity and bioaccumulation, once entering the water body, will be strongly distributed into the water body sediments and become the accumulation pool of HOPs. [0003] Due to the complexity of the ecological environment of natural water bodies and the variability of natural conditions, the physicochemical treatment method of adding chemical agents and the ex-situ biological treatment technology of reactors are not practical. Combining the u...
