This project developed by combining CFSBR processing systems and membrane filtration systems, through CFSBR biological treatment systems effectively remove organic carbon and nitrogen of phosphorus nutrients, through membrane filtration system to decrease further the concentration of the suspended solids and TCOD , let effluent water to conform the recommended value of the reuse water quality.
In monitoring control develop device, which can be measured water level, MLSS concentration and SS concentration by laser light. Water level measurement results compared with the previous measurement methods, the relative error is less than 1%, MLSS concentration measured relative with commercial instruments error less than 5%,and can effectively measure the concentration of SS. In automatic control, control of dissolved oxygen beating range is less than 10% ,by operating can decrease influent ammonia 82 mg / L to less than 10 mg /L, and nitrite less than 1 mg / L and nitrate less than 1 mg/L.
By adjusting the cycle of the operation can be treated the high concentration of ammonia nitrogen to meet emissions standards ,and combined with membrane filtration system, will further reduce the concentration of COD, so MCFSBR effluent water treatment system can conform the recommended value of the reuse water quality.
