Treating method for swage-wastewater of high concentration using ultra-fine bubble as well as dissolved oxygen tank

摘要

The present invention provides ultra-fine cells and dissolved oxygen baths in high concentration sewage and wastewater treatment processes of suspended solids (MLSS) 10,000 mg / L or more, such as livestock wastewater treatment plant, leachate treatment plant, food wastewater treatment plant, sanitary manure treatment plant, wastewater end treatment plant, and sewage treatment plant. The present invention relates to a method for treating high concentration sewage water by maximizing dissolved oxygen concentration, thereby improving the efficiency of organic decomposition and nitrogen removal by microorganisms, and more specifically, a coarse generated from a blower and an acid pipe provided at the lower side of the aerobic tank. By aeration of the bubbles in the aerobic tank, oxygen is delivered to the aerobic microorganisms while preventing activated sludge from being deposited in the lower part of the aerobic tank; Inside the aerobic tank, a plurality of dissolved oxygen tanks, which are closed on the upper side and open on the lower side, constitute the ultra-low intensity bubbles generated from the pressure-dissolved method or the atmospheric pressure type ultra-miniaturized bubble generator, and the impact slant plate and the jet stream forming tree. And dispersing the dissolved oxygen bath in water using a plurality of dispersing devices including a jet port, thereby increasing the dissolved oxygen concentration of the dissolved oxygen bath; A denitrification circulation tank is connected after the aerobic tank, and the nitrified liquid nitrified in the aerobic tank and the dissolved oxygen tank is naturally transported to the denitrification circulation tank via a nitride liquid transfer channel provided under the separation wall; The nitriding liquid transferred to the denitrification circulation tank is a denitrification reaction and gravity precipitation under anoxic conditions inside the denitrification circulation tank, whereby nitrogen components and water pollutants are removed; Dissolved oxygen bath; Denitrification circulation tank; And it provides a high concentration sewage wastewater treatment method comprising a pressure-dissolving method to atmospheric pressure ultra-fine foam generator.
