Abstract

The invention relates to municipal domestic wastewater treatment and comprehensive recycling equipment and a method thereof. The equipment comprises a pipeline mixer, a metering pump, a seston filter, a chemicals feed tank, a fiber ball filter, a three-dimensional photoelectric reactor, a biomembrane reactor, a CIO2 disinfecting tank, a water storage tank, a security filter element and a pressure pump. Bathing wastewater produced in urban life is intensively collected and is conducted to novel polyester high elastic filament micro-flocculation fiber filtering and deep oxidation biological combined treatment, outlet water meets requirements of the reuse of urban recycling water-water quality standard for urban miscellaneous water consumption and can be recycled to be used for washing toilets in hotels and greening, residual ultrafiltrated outlet water is conducted to the biomembrane reactor device and disinfecting treatment, and treated outlet water meets the requirement of drinking water sanitary standard (GB5749-85) and then can be recycled to be used for links of laundry and bathing in hotels with higher water quality requirements. The method and relevant equipment flows are simple and easy to operate and manage, and are very suitable for the reclaimed-water recycling of municipal domestic wastewater.
