Lu Ning mine sewage treatment station located in the east office area, the design capacity 1100m 3 / d.
process characteristics:
1 This project uses the SBR method has a small footprint, no secondary sedimentation tank, anaerobic tank, an area than the traditional approach by 30%, the investment savings of 20% -40%; and handling flexible water by runoff water change is small, good shock load;
1 using online dissolved oxygen aeration blower and the drive joint control, not only to improve the treatment effect, and can save energy 30% ~ 40%;
1 Siemens PLC systems, and Taiwan Advantech IPC joint control, to achieve control of the fully automated, and reliable. Under normal operating conditions to achieve unattended. The management of simple, reliable operation;
