Municipal domestic wastewater treatment and comprehensive recycling equipment and method thereof

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.

Description

technical field [0001] The invention belongs to the technical field of urban domestic wastewater treatment, and in particular relates to a comprehensive recycling device for urban domestic wastewater treatment and a method thereof. Background technique [0002] Building reclaimed water engineering refers to the reuse of domestic sewage and cooling water discharged from people's living or production activities in public buildings or building communities for use in buildings or building communities through collection, water treatment, water transmission and distribution technologies. The regenerated water can be used as miscellaneous water for flushing toilets, watering streets, greening, water features, car washing, air conditioning cooling, fire fighting, etc. Urban domestic sewage mainly includes kitchen washing water, toilet flushing wastewater and other domestic miscellaneous water. This type of wastewater contains a large amount of suspended solids, chemically or biolog...
