摘要：

Thermal sludge conditioning liquor from a municipal wastewater treatment plant was successfully treated with a pilot-scale upflow anaerobic hybrid reactor with an effective volume of 10.4 cu.m. More than 70% of soluble COD in the influent was removed even at an organic loading as high as 30 kg COD/cu.m/day. Though the reactor was seeded with an anaerobically digested sludge, granular sludge was produced in the reactor. The ratio of granular sludge to the solids in the reactor increased up to about 70% at the end of experiment. Biological activity of the granular sludge was measured as a methane producing rate using an acetate solution. Physical characteristics of the sludge, such as diameter distribution, composition and settling velocity, were also measured. It was found through tracer tests using lithium chloride that the reactor worked as a CSTR.
