Abstract

Disclosed is a variable sewage treatment apparatus comprising: a sewage treatment tank including an anaerobic tank in which sewage phosphorus is discharged, an anoxic tank in which nitrate-nitrogen transferred from an aerobic tank is denitrified without feeding nitrate oxygen, and an aerobic tank in which organic matter is decomposed and nitrified; a first adjustable membrane which partitions the anaerobic tank and the anoxic tank, and is adapted to be mobile in the sewage treatment tank to adjust the volume of the anaerobic tank and the volume of the anoxic tank relative to one another; a second adjustable membrane which partitions the anoxic tank and the aerobic tank, and is adapted to be mobile in the sewage treatment tank to adjust the volume of the anoxic tank and the volume of the aerobic tank relatively to one another; an adjustable membrane moving unit which moves the first adjustable membrane and the second adjustable membrane; an air supply unit including a plurality of air nozzles for supplying air to the sewage treatment tank, an air pump for supplying air to the air nozzles, and a valve for selectively shutting the air pump and the air nozzles; and a recycle unit which resupplies sewage from the aerobic tank to the anoxic tank.

Description

technical field [0001] The present invention generally relates to an advanced wastewater treatment device with an adjustable separation membrane, and more particularly to an improved biological treatment process for sewage and wastewater, thereby enhancing the A2O (anaerobic-anaerobic-aerobic) process of the advanced wastewater treatment process An advanced wastewater treatment device with an adjustable separation membrane that achieves high treatment efficiency and stable treated water quality. Background technique [0002] The general sewage and wastewater treatment process is a biological process using activated sludge, in which aerobic microorganisms oxidize organic matter in sewage and wastewater under aerobic environmental conditions, thereby reducing the concentration of organic matter in the treated water. Settling tanks are operated to maintain the concentration of microorganisms in the reaction tank and to prevent discharge of particulate and activated sludge into ...
