Hydrolyzed acidification filler

Microbial attachment to the packing can increase the contact area between sewage and microorganisms, and improve the treatment efficiency of the hydrolysis acidification tank. The bottom of the hydrolysis and acidification tank is equipped with a water distribution system, which uses the reflux sludge from the secondary sedimentation tank to stir the sludge at the bottom of the hydrolysis and acidification tank, making it in a suspended state and fully mixed with the incoming wastewater, thereby improving the treatment efficiency of the hydrolysis and acidification tank and reducing the load of subsequent aerobic treatment.
