Simple treatment of miscellaneous living waste water

Abstract

Abstract PURPOSE:To treat efficiently the miscellaneous living waste water which is subjected to a sepn. of solid materials and does not contain crude night soil by supplying said waste water in upward countercurrent to a tank packed therein with a support for microorganisms and supplying a specific volume of air into the packed tank from below thereby treating microbial the waste water. CONSTITUTION:Miscellaneous living waste water 1 which is produced in a home kitchen, bathroom, dining room, etc. is introduced into an adjusting tank 2, where the water is stagnated for 2-12hr and the greater part of solid materials are separated. The waste water is then supplied in upward countercurrent into a microbial treating tank 4 packed therein with a support for microorganisms over the entire part. Air is then supplied into the tank from below the support for microorganisms at a superficial linear velocity of 5cm/min to decompose the org. pollutant in the waste water at a microorganisms concn. of 5-15g/l per tank 4. The waste water after the microbial decomposition is introduced into a phosphorus removing tank 5 packed therein with a phosphorus removing agent so that the phosphorus contained therein is removed.
