. Sewage And Wastewater Advanced Treatment Method Used The Fixed Biological Contactor And The submerged Membrane

摘要

The present invention relates to a device for purifying sewage, wastewater and sewage, and in particular, a biological treatment method using a rope-type fixed bed contact medium and a physical treatment method using an immersion hollow fiber membrane are used to purify wastewater and sewage. The system relates to a screen tank for removing large suspended solids flowing into the waste water and sewage,;A flow adjustment tank for adjusting the flow rate of the influent water through the screen;;A flow regulating pump for transferring the wastewater, wastewater and sewage of the flow regulating tank to the contact oxidation tank;;A contact oxidation tank for decomposing organic matter in the wastewater and wastewater introduced from the flow rate adjusting tank by a microorganism using a primary rope type fixed bed contact medium;;A membrane separation tank for secondary treatment and solid-liquid separation of the first treated water introduced from the contact oxidation tank;;A suction pump for discharging the first treated water through the immersion type hollow fiber membrane in the membrane separation tank and discharging only the second treated water to the outside;;A sludge conveying and conveying pump for conveying and discarding sludge generated in the membrane separation tank;;A sludge storage tank for collecting excess sludge generated in the membrane separation tank;;Wastewater and sewage purification apparatus, characterized in that consisting of a blower for supplying oxygen to the flow rate adjustment tank, contact oxidation tank, membrane separation tank, sludge storage tank and sludge transfer pump.
