Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dipping type membrane separation sewage treating apparatus equipped with an advanced type aerator having reduced filtration resistance of a filtration membrane and reduced filtration pressure, and to provide a method for advantageously using the dipping type membrane separation sewage treating apparatus.SOLUTION: A solid-liquid separation module comprises: a diffuser tube; and a filtration unit which has a separation membrane formed by superposing PTFE films having minute through holes on both surfaces of a polyethylene terephthalate film having through holes. Since the solid-liquid separation module has little clogging and small filtration resistance, filtration pressure is small, a running cost of a membrane separator can be saved and further service life is long.
