Embodiment 1
[0024] Example 1. like figure 1 As shown, the landfill leachate is processed according to the following steps: a. Pretreatment, the landfill leachate from the waste storage pit is collected and then enters the primary sedimentation tank for precipitation. The leachate enters the primary sedimentation tank from the central pipe of the primary sedimentation tank. At the bottom of the tank, most of the impurities and sludge are deposited and then pumped back to the garbage storage pit by the sludge pump, which plays a role in reducing water quality and protecting the subsequent system (especially ultrafiltration). The clarified garbage leachate overflows to the regulating tank. Stay in the pool for 7 days to adjust and store the flow, which not only plays a role of homogenization, but also plays a buffer role for the rainy season or the maintenance of the treatment system;
[0025] b. Anaerobic treatment. The landfill leachate is lifted by the pump into the bottom of the reactor...
