Research for Operation Stability of TUSB Reactor and the Feasibility in Organic Wastewater Treatment

Abstract:

According to the design concept of UASB reactor with three-phase separator, a suite of self-made TUSB reactor was produced. The operational characteristics of the reactor were tested after the reactor completed start-up, and analyzed the factors that affected the COD removal rate. The results show that, as the load changes rapidly, although there was a short decline on removal efficiency; the system still can adapt to the changes quickly, and return to its original level; the load continually increases, then the removal rate tends to be constant; the same time as the volumetric loading rate increases, the gas yield is on the rise. It is proved that the reactor technology has the resistance to flow and anti-impact load capability; meantime it also shows that the high volumetric loading rate within the two-phase separation can retain the sludge, avoiding UASB sludge wastage washout under high-load operation.
