摘要
Problem to be solved: to provide a membrane separation activated sludge apparatus and a method and a raw water supply device capable of efficiently performing denitrification and improving nitrogen removal efficiency in a separation membrane type type membrane separation activated sludge treatment method.A single reactor for aerobic treatment and anoxic treatmentThe immersion membrane separation unit disposed inside the reaction vessel isA partition plate type membrane separation activated sludge treatment apparatus having aeration meansIn a membrane separation activated sludge processing apparatus having a liquid level control means for switching the liquid level in the reaction vessel to a state higher than the upper end of the partition plate and to a low stateThe liquid level in the reaction vessel is lower than the top edge of the partition plateWhen the compartment outside the partition is anoxicA membrane separation activated sludge treatment apparatus characterized in that a raw water supply means for supplying raw water in a reaction tank to a partition outside the partition plate is provided with a quantity of water not exceeding the upper end of the partition plateMethod for treating membrane separation activated sludgeAnd raw water supply equipment.Diagram
