The Application Of CAST In Shuangyang Wastewater Treatment Plant

Wastewater treatment engineering as a conduct of environmental protection item, for the protection water resources, prevention and control various infectious disease, raise residents health level, there is important function.This text introduced a CAST craft to used for the design, craft control of city wastewater treatment parameter and concrete movement .To cold region the type's craft adjust to try to circulate have already drawn lessons from meaning more.The bio-chemical tank circulates the period as 4h: two hours influent\ aeration\ backflow, one-hour sedimentation, one-hour drain\row of sludge\unused. 4 pool sequence of rotation, into a single pool intermittent, water, but in the whole enters, the water leakage continuously.When the water temperature is 11℃, after passes through 20 day-long raises and the debugging, COD, SS, NH3-N and TP removing rate respectively is 88.9%, 92.8%, 64.3% and 81.1%, each water leakage water quality target and the active sludge target achieved or surpasses the design goal,Successfully has realized under...
