Combined with the advantages of activated sludge watsewater treament and biofilm watsewater treament, HBF process can degrade COD and ammonium at the same time. HBF is a hybrid continuous/batch treating system developed based on the theories of continuous plug reaction, batch reaction and precipitation separation. It includes series processes of pre-denitrification, aerobic nitrification, post-denitrification and two alternatively operated sequence batch reactors. HBF integrates the biological nitrogen removal ability of two stages A/O (a process and the sequencing reaction or settling characteristics of SBR). The aerobic and SBR reactors are packed with our own products, fixed plate biofilm carriers, which can create a favorable ecological environment and proper hydraulic condition for the growth of dominant microorganisms.

Fixed plate biofilm carrier is developed by Tongji University for biological wastewater treatment plant. It is a new generation microbial immobilized carrier based on years of engineering practise. This filling material has been widely applied in the treatment of refractory organic wastewater. It has special structure shaped by a series of complex processes with bilayer films and interstice layer, so it possesses large specific surface area and high porosity properties. After ionized and hydrophilic modification during the shaping processes, the material surface is positively charged, so it is easier for negatively charged microorganisms to attach. Fixed plate biofilm carrier has excellent mechanical strength which ensures no damage under the hydraulic shear or during collision process between two packing material, Besides, this high polymer material can resist acid or alkali with more than 8-10 years lifespan.

As a biocarrier in bio waste water treatment plant, fixed bed biological filter has been widely used in small sewage treatment projects over the world. Material for the bio sewage treatment plant is the modified HDPE, a high quality plastic in polyolefins with corrosion resistant, high temperature resistant, aging resistant, and adding uv resistance, oxidation resistance, water and other additives to improve the performance during bio sewage treatment plant, after the special processing, it is tailored for sewage treatment, the service life can reach more than 20 years. Fast filming speed, large amount of film carring, stable operation, strong impact resistance capacity. Complete mixing of air and water, three-dimensional flow, excellent treatment effect; Stable structure, flexible combination, suitable for various areas.
