Title: APPARATUS FOR TREATING WASTEWATER AND A SYSTEM FOR COLLECTING AND TREATING WASTEWATER COMBINING RAINWATER DRAINAGE
Abstract:
The present invention relates to an apparatus for collecting and treating wastewater (1) based on biodegradation - recombination - biodegradation process, comprising: a shell (1.1), the space inside the shell is divided into a first chamber (1.2) and a second chamber (1.3) by a divider wall (1.4), wherein: the first chamber (1.2) contains biological medium suitable for heterotrophic microorganisms growth; the second chamber (1.3) contains biological medium suitable for autotrophic microorganisms and heterotrophic microorganisms growth. The present invention also relates to a system for collecting and treating wastewater combining rainwater drainage used for building, comprising: at least one wastewater treatment apparatus (1) above; a indoor pipe system for collecting and transfering wastewater, rainwater comprising a main vertical pipe (2), substantially horizontal branch pipes; and a outdoor pipe system for transfering wastewater combining rainwater drainage comprising a horizontal pipe (3) for connecting the indoor pipe system for collecting and transfering wastewater, rainwater to at least one wastewater treatment apparatus (1) above.
