Does the hydrolytic acidizing tank need a filler

The hydrolytic acidizing tank can be fitted with packing. In fact, the filler is to provide a growth platform for microorganisms. The attachment of microorganisms on the filler can increase the contact area between sewage and microorganisms and improve the treatment efficiency of the hydrolytic acidification pool.
Simply put, the filler is the adhesion bed of bacteria, which increases the biomass and improves the contact surface of microorganisms and wastewater. A water distribution system is installed at the bottom of the hydrolytic acidification pool. The return sludge of the secondary sedimentation tank is used to agitate the sludge at the bottom of the hydrolytic acidification pool, so that it is in suspension state and fully mixed with the incoming wastewater, thus improving the treatment effect of the hydrolytic acidification pool and reducing the load of subsequent aerobic treatment.
Combined packings carrier is usually used.
