Embodiment Construction

[0032] see figure 1 . The device for deep purification treatment of biological turntable effluent provided by the present invention, its main structure includes:

[0033] The bottom of the nano-aeration and ablation device 4 is provided with a mud outlet 42, and the inside of the nano-aeration and ablation device 4 is located above the mud outlet 42. A nano-aeration disc 30 is arranged, and the nano-aeration disc 30 is connected to a nano-aeration machine 28. A stirrer 43 is installed above the air tray 30 . A heating belt 2 and a temperature-sensing control head 3 are installed on one side of the nano aeration ablation device 4 , and the heating belt 2 and the temperature-sensing control head 3 are controlled by a temperature controller 1 . The bubbles generated by aeration are evenly mixed into the sewage, and the sewage is treated with nano-aeration under the condition of high-temperature nano-aeration, and the hydraulic retention time in the nano-aeration ablation device...

Abstract

The invention provides a device for carrying out deep purification treatment on effluent by utilizing rotating biological contactors. The device mainly comprises a nano aerated ablation device, a rotating biological contactor pool, a nano aerated coagulation-micro-vortex flocculation device, a three-stage backwashing and screening device and a photocatalytic degradation reaction device. The invention also discloses a method for treating sewage by utilizing the device. The device is easy to operate and convenient to maintain, is especially suitable for treating wastewater which is in large quantity, is difficult to degrade and has high turbidity.

Description

technical field [0001] The invention relates to a device for advanced purification treatment of effluent water from a biological turntable. [0002] The invention also relates to a specific method for deeply purifying sewage by using the above-mentioned device. Background technique [0003] At this stage, some organic substances that are difficult to biodegrade enter into wastewater in large quantities, making wastewater one of the most polluted and most difficult to treat industrial wastewater. Therefore, the wastewater treatment methods still based on biochemical methods cannot meet the actual needs. Therefore, in recent years, all countries have carried out the exploration and research of new biological treatment processes, efficient specialized bacteria and new chemical agents. [0004] Wastewater from industrial areas has the characteristics of high concentration, high toxicity, and difficulty in biodegradation. Solving the problem of organic industrial wastewater tre...
