<p>A water reclamation and reusing system for building which substantially relieves fouling of the filtration process caused by empty loads in a balancing tank and an aeration tank, and can reduce installation and operating costs by simplifying the water reclamation and reusing process is provided. A water reclamation and reusing system for building comprises: a flow equalization tank(11) that only relieves load fluctuations, but also stores wastewater flown in when excessive raw water is generated so as to perform effective biological treatment of wastewater passing through a grit chamber and a screen tank(10) when a BOD load of raw water exceeds 30 ppm; a bio-contact oxidation tank(12) installed in front of the flow equalization tank to maintain activity of microorganisms; and a pretreating filter(13) and a microfiltration membrane(14) installed between the flow equalization tank and an intermediate storage tank(15) to filter microorganisms and solids contained in treated water partially flown over the flow equalization tank and the bio-contact oxidation tank.</p> |
