Study on Intelligent Controlling Sequencing Batch Biofilm Reactor for Treatment of Domestic Wastewater
A novel type of lab-scale innovative sequencing batch biofilm reactor (SBBR) was developed to treat domestic wastewater, in which an acryl cylinder (diameter 70 mm, height 200 mm) was equipped and many fiber threads were attached to the surface of the cylinder as the bacteria carrier. Fiber threads served as filter media to minimize the concentration of suspended solids in the effluent. No time and volume for settling was required in this system. After one year’s operation, each parameter achieved the wastewater discharged criterion in 2 cycles (4 h). It was found that COD removal efficiency was up to 90% in 3 h, and ammonium nitrogen concentration approached the least value; total nitrogen removal efficiency reached 55%-71%. In this SBBR system simultaneous nitrification and denitrification was completed at the end of 2 cycles.
