Wastewater treatment system using anaerobic-aerobic biotreatment biofilm reactor filled with waste tire

摘要

TECHNICAL FIELD The present invention relates to a wastewater treatment apparatus using an anaerobic-aerobic two-stage biofilm reactor packed with a waste tire, and a treatment method of a refractory wastewater using the same. The wastewater treatment apparatus of the present invention comprises (i) an inflow water tank for containing biodegradable material; (ii) an anaerobic biofilm reactor filled with waste tire flakes for primary treatment of incoming wastewater; (iii) a methane gas collection tank for collecting methane gas generated in the electro anaerobic biofilm reactor; (iv) aerobic biofilm reactor packed with waste tire flakes for secondary treatment leading to complete degradation of the intermediate treated first in the anaerobic biofilm reactor; And (v) an effluent collecting tank for collecting effluent discharged from the aerobic biofilm reactor. The apparatus and method for treating wastewater of the present invention have the following advantages and characteristics; Wastewater treatment equipment has a top-down flow and utilizes a biofilm reactor packed with waste tire flakes, so it is economical in terms of minimizing the required power and recycling waste. The anaerobic biofilm reactor not only generates methane gas that can be reused, but also has primary treatment ability for the degradable material, which reduces the toxicity of the degradable material by induction of reductive de-functional group reaction and increases the biological treatment capacity /RTI By directly connecting the anaerobic biofilm reactor with the secondary treatment capable of completely decomposing the produced intermediate product to the anaerobic biofilm reactor, the activity of the microorganisms existing in each reactor was maximized, and the biodegradability Effectively treats the material. (3) Since anaerobic digestion sludge of a general sewage treatment plant is used for anaerobic sludge treatment and activated sludge is used for aerobic treatment, the present invention is effective for treatment of industrial wastewater containing various refractory substances such as chlorinated organic compounds.
