Waste water regenerating apparatus

Abstract

Abstract PURPOSE:To achieve the re-utilization of waste water, by providing a hair catcher, a submerged filter, a permeable membrane type filter and a sterilizing means and to certainly removing various objects to be collected in waste water to effectively purify waste water. CONSTITUTION:A waste water tank 1 for gathering and storing waste water is arranged in a regeneration line provided in order to regenerate waste water. The solid impurities in waste water are collected by a hair catcher 4 equipped with a perforated filter body and, further, the suspended substance in waste water is collected by a submerged filter 5 equipped with a granular bed filter body and bacteria in waste water are removed by permeable membrane type filters 16, 17 equipped with semipermeable membrane filter materials. Further, in a regenerated water storing tank 21, purified and regenerated water is stored and a sterilizing means 7 applies sterilizing treatment to flowing water in a regeneration line. As a result, various objects to be collected in waste water are respectively certainly removed to effectively purify waste water and the re-utilization of waste water can be effectively achieved.
