Water treating device for photosynthetic biological coupling bioelectrochemical membrane bioreactor

Abstract

The invention discloses a water treating device for a photosynthetic biological coupling bioelectrochemical membrane bioreactor, and belongs to the technical field of biological sewage treatment recycling and reutilization. The water treating device is characterized in that an anode chamber is provided with a water inlet pipe and a diffusion passage, filled with graphite particles, and attached with electricigens; a through hole is formed in the wall of the anode chamber; a non-woven fabric covers the outer side of the anode chamber; the upper part of the anode chamber is kept out of the sun; the outer side of the through hole is sleeved with a conductive filtering separating membrane; green algae photosynthetic microorganisms grow in a cathode chamber on the outer side of the conductive filtering separating membrane in a suspending manner; water is filtered from the top of the cathode chamber through the conductive filtering separating membrane; the bottom of the cathode chamber adopts a funnel structure used for discharging residual green alga; a load resistor is connected with the outside of an anode and the conductive filtering separating membrane which are connected with each other through a conducting wire. The water treating device has the effects and benefits that not only are energy consumption behaviors such as manual aeration avoided, but also the denitrification effect is good, matters such as nitrogen, phosphorus and organic matters in water can be removed during electricity generation, and surplus green alga can be further utilized, so that the energy consumption in waste water treatment is reduced, and added value is generated.

Description

technical field [0001] The invention belongs to the technical field of wastewater biological treatment reuse and resource utilization, and relates to a photosynthetic biological coupling bioelectrochemical membrane bioreactor water treatment device. Background technique [0002] The cost of cathode materials for ordinary microbial fuel cells is high, and it has not been practically applied in wastewater treatment. In addition to air cathodes, artificial aeration is generally used to maintain the dissolved oxygen content in water, resulting in energy consumption. higher. In membrane bioreactors, membrane modules are expensive and prone to clogging. Although photosynthetic microbial fuel cells can reduce the energy consumption to maintain the necessary dissolved oxygen level, the effluent without membrane filtration cannot meet the high requirements for wastewater treatment and effluent quality.
