Biological treatment and equipment for denitrification, reaction, sedimentation tank, vertical integrated sewage, sewage and wastewater

摘要

The present invention relates to a denitrification / denitrification system capable of simultaneously performing a biological treatment and a precipitation treatment in a single treatment tank composed of vertically integrated type denitrification tank, a reaction tank and a settling tank for removing nitrogen components contained in sewage, sewage and wastewater The present invention relates to a biological treatment method and apparatus for sewage, sewage, and wastewater, which is a vertically integrated type settling tank, comprising a conventional screening step for filtering a suspended matter having a large amount of particles present in influent water and a step for adjusting concentration and flow rate of influent water A denitrification step of removing nitrogen contained in influent water supplied from the flow rate adjusting tank step by an anaerobic reaction, a reaction step of contacting and enhancing the microorganisms with the microorganism contact agent by aerating action and autolysis And a sedimentation process in which the activated sludge is precipitated and the supernatant is drained into a conventional effluent tank A process for purifying contaminated water by a process comprising an integrated treatment process for allowing nitrogen to be removed from the denitrification tank to be carried out in a vertically integrated structure, and a denitrification tank for removing nitrogen components contained in influent water as anoxic treatment, A denitrification reaction tank in which the denitrification tank and the reaction tank are integrally formed so as to form a reaction tank having a plurality of microorganism contact members stacked thereon for contacting, proliferating and self-decomposing microorganisms contained in influent water; The sedimentation tank for collecting the treated primary treated water in the reaction tank, the activated sludge settled, the secondary treated water flowing out through the secondary tank feeding line, and the reaction tank, the denitrification tank and the settling tank are integrated And the integrated processing structure formed as a vertically integrated type.
