Abstract

The invention relates to a biology-electrochemistry compound system for processing dye waste water and the operation system. The micro-electrolyzing filter connects to biological film oxygen aversion reactor through pipeline. The liquid outlet of reactor connects solid recycling integration oxidation channel through pipeline. The liquid outlet of oxidation channel connects to electrolyzing flocculating chamber. The gas outlet of oxidation channel and reactor connects to biology deodorization reactor through pipeline. The invention would improve the biochemistry feature of the waste water, and oxidation channel could remove the organic in water, the electrolyte tank could remove suspended particle, and the biology deodorization reactor would remove the odor from waste water. The invention could make the water quality after being processed reach the national standard of complex discharging.

Description

technical field [0001] The invention belongs to the technical field of treating dye wastewater by utilizing the synergistic effect of biotechnology and electrochemical technology, and in particular relates to a bio-electrochemical combined system for treating dye wastewater and an operation method thereof. Background technique [0002] Dye wastewater is a kind of high-concentration industrial wastewater that is harmful and difficult to treat. It contains a variety of pollutants. The main water quality characteristics are: high COD concentration, high chroma, high concentration of refractory organic matter, and large fluctuations in water quality. At present, the main technologies for treating dye wastewater at home and abroad include biological treatment and physical and chemical treatment. And biofilm, etc., biological treatment technology has the advantages of economy and simplicity and is widely used. [0003] The current technology for treating dye wastewater has the fo...
