Abstract
The invention provides a bioelectrochemical coupling aluminum built-in electric field water treatment system and belongs to the technical fields of new energy and wastewater treatment. According to the coupling system, a microelectrolysis / electric flocculation process is creatively introduced, a trickling filtration and empty tower contact oxidation bed process is arranged in the treatment process, and multiple process technologies are coupled, so that the problems of low water quality of effluent subjected to high-load sewage treatment and great fluctuation are solved, addition of a chemicalflocculating agent is replaced by electric flocculation, and the operation cost can be obviously reduced; a micromotor and bioelectrochemical system generates electricity stably and the electrodynamicpotential is high, so that the repulsive interaction of a conductive cathode membrane polluted medium is intensified, and the operating cycle and the service life of a membrane bioreactor are obviously prolonged; the coupling system is completely prepared from cheap raw materials, no chemical agents are introduced during operation, low-cost treatment on high-load sewage can be realized, the waterquality of the effluent after treatment is high, up-to-standard discharge or recycling is realized, the application range is large and the application potential is large.
Description
technical field [0001] The invention belongs to the technical field of new energy and wastewater treatment. The specific research and development content is to use elemental aluminum as the sacrificial anode of the bioelectrochemical system. The sacrificial aluminum anode and the activated carbon filled in the anode chamber naturally form the primary battery and the micro-anode and micro-cathode of the micro-electrolysis due to the different potentials. , to achieve the natural release of aluminum ions; the self-built micro-electric field of the bioelectrochemical system triggers the anode aluminum micro-electrolysis to realize the electrocoagulation process, and continuously produces flocculation and precipitation for organic and inorganic substances in high-load wastewater to achieve high-load wastewater purification treatment. In this system, in order to strengthen the biodegradation effect of the system and realize the continuous enhanced treatment of the polluted medium, a...
