The hybrid waste water treatment method using the submerged membrane process combined with activated carbon

摘要

The present invention for performing a biological oxidation decomposition of the contaminants as a kind of an immersion type membrane separation process (physical treatment) and a waste water purification process technology using the activated carbon adsorption step a mixed high processing mixed (biological treatment) (Hybrid Membrane bioreactor) process the active microbial population (activated sludge) and other particle components separated and treated as excluded by the membrane by relates to a waste water treatment method of activated carbon the membrane separation process for the mixture to achieve a high degree of water quality.; A first feature membrane aeration tank (14) inside the activated carbon mixed In tank 10 wastewater treatment Activated Membrane blending method according to claim that since In the activated carbon directly to the present invention, the separated second feature film aeration tank 14, the activated carbon to the digester serves anaerobic to aerobic activated carbon sludge within the sludge concentration tank 13 is transferred to the waste water treated activated carbon method membrane blending operations for which is characterized in that to restore the activated carbon adsorption capacity at the same time as the biological denitrification process with a , a third feature is the waste water, characterized in that to the activated carbon sludge regulates the microbial concentration in the concentration tank (anaerobic digestion) 13 and the film separated by circulation and transport to the breathable membrane aeration tank 14 an aeration tank 14 an activated carbon membrane separation method for blending process.; Above the present invention by carrying out the carrier serves to inject the activated carbon directly to the aeration tank and enable colony formation of the microorganism, and at the same time improving the removal rate of dissolved organic matter Sikkim by creating a microorganism membrane (Bio film) on the activated carbon surface from the aeration tank bottom of the membrane surface washing effect can be obtained by the upward water flow generated by the aeration.
