[0002] The core of biological contact oxidation method is the formation of biofilm and the action of microorganisms. Biofilm is a complex ecological system composed of microorganisms, water, gas and solid suspended matter. When wastewater enters the biological contact oxidation tank, the organic matter in the wastewater is adsorbed and decomposed by the microorganisms on the biofilm, and energy and carbon dioxide are generated at the same time. When the biofilm grows to a certain thickness, the microorganisms near the filler wall will perform anaerobic metabolism due to lack of oxygen, and the gas generated and the scouring effect of aeration will cause the biofilm to fall off and promote the growth of new biofilm, forming the metabolism of biofilm.

Using corrosion-resistant stainless steel, compared to traditional carbon steel supports, it overcomes the corrosion problem common in traditional biological contact oxidation methods, effectively improving reactor stability and cost-effectiveness. Lifting lugs 3 are installed on the top of the frame 1 for easy overall hoisting. Multiple sets of matrix-distributed biological packing modules 2 are installed on the frame 1. Each biological packing module 2 includes a biofilm packing support fixed to the frame 1. Biofilm packing cylinders are installed on the biofilm packing support and filled with biofilm packing. The biological packing uses a curtain-like structure, greatly increasing its surface area. Through a reasonable spacing layout, the solid, liquid, and gas phases are well transferred, effectively preventing excessive biofilm shedding due to water flow impact and avoiding the impact of packing aging or clogging on treatment efficiency. The bottom of the frame 1, located below the biological packing module 2, is equipped with an aeration branch pipe 7. The aeration branch pipe 7 is fastened to the frame 1 by fixing pipe clamps 9, which can achieve quick and stable fixation of the aeration branch pipe 7. Microporous aeration discs 8 are evenly installed on the aeration branch pipe 7, facing upwards and directly towards the biological packing module 2. In actual operation, the microporous aeration discs 8 achieve uniform aeration, ensuring sufficient dissolved oxygen for microbial growth. Vertically arranged guide rods 5 are installed on the frame 1. The main aeration pipe 4 is fastened to the guide rods 5 by fixing pipe clamps 9, which can achieve quick and stable fixation of the main aeration pipe 4.
