Wherein, leachate is through directly entering membrane treatment room of sedimentation tank sediment supernatant after biochemical pond treatment, because current sedimentation tank volume is limited, and settling time is insufficient, mud-water separation is incomplete, contains a large amount of suspended solids in the supernatant, leads to follow-up membrane treatment stage load increase, and membrane module life-span reduces, and maintenance cost increases. Therefore, it is a technical problem in the field how to improve the above-mentioned state of the art without changing the production process of the leachate treatment station of the existing landfill.

Meanwhile, under the anaerobic condition, the gas generated by anaerobic digestion can interfere with the precipitation of the sludge when rising, and the sludge falling off from the plate is brought to the water surface to form a sludge layer. However, when the capacity of secondary sedimentation is required to be further enlarged in some sewage treatment plants, the treatment efficiency is improved by adopting a diagonal sedimentation tank due to the limitation of occupied area, so that a novel diagonal sedimentation tank is urgently needed to be designed to solve the problems.
