Volume load: anaerobic zone (or hydrolysis zone) is 4~8kgCODCr/(m3·d); aerobic zone is 0.3~0.8 kgCODCr/(m3·d). Hydraulic retention time: less than 48h for anaerobic-aerobic integrated bioreactor; less than 24h for hydrolysis-aerobic integrated bioreactor. In addition, the upward flow rate of water in the upflow integrated bioreactor should be less than 1m/h. Upflow integrated bioreactors should use multi-point water distribution devices. The water distribution device should use a single-tube porous water distribution device, and the water inlet point should be kept at a distance of 150~250mm from the bottom of the reactor, etc.
