AI Technical Summary
Traditional aeration devices suffer from low aeration efficiency and cannot achieve rapid treatment of landfill leachate due to limited oxygen transfer rate and uneven dissolved oxygen distribution when treating high-concentration leachate.
Design a leachate recycling waste resource utilization device, including a pretreatment tank, a biological reactor, and a deep treatment tank. By setting up a moving block, a moving component, a first pipeline, an aeration pipe, and a circulation pump, ensure uniform aeration treatment of leachate in the biological reactor, and realize the circulation flow of leachate through the circulation pump, thereby increasing the contact area and contact time between leachate and air.
Uniform aeration of leachate was achieved, which significantly improved the decomposition rate of organic matter, increased treatment efficiency, and ensured the continuity and high efficiency of the treatment process.
