摘要
A water treatment system using a granular activated sludge and a membrane bioreactor that can reduce the installation area of a complex water treatment system, improve the treatment efficiency of pollutants such as organic matter, nitrogen, and phosphorus, and perform advanced water treatment, and Providing that method. An indirect aeration tank 100 for supplying air so that dissolved oxygen contained in raw water reaches a saturated concentration, and floating microorganisms contained in treated water that has passed through the indirect aeration tank 100 are granulated. And a granulated tank 200 with a sludge blanket, which is disposed in the upper part of the granulation tank 200 and has a movable membrane 500 movable in the granulation tank 200. Processing system. [Effect] Effectively removes pollutants contained in raw water, minimizes the installation area of the combined water treatment system, improves the treatment efficiency of pollutants such as organic matter, nitrogen, phosphorus, etc., installation cost In addition, the effect of reducing operating costs can be obtained.
