Underground sewage treatment plant

The effect of solid-liquid separation is much better than that of the traditional sedimentation tank, the quality of the effluent is good, the suspended matter and turbidity of the effluent are close to zero, and the effluent can be reused directly.

The sludge concentration is high, the microorganism is completely retained in the Bioreactor, the hydraulic retention time (HRT) of the reactor and the sludge retention time (SRT) are completely separated, and the control is flexible and stable.

Because the aeration tank of traditional sewage treatment and the secondary sedimentation tank are combined into one by the MBR, and all the process facilities of the tertiary treatment are replaced, the land occupation area is greatly reduced and the civil construction investment is saved.

The removal of ammonia and phosphorus can also be achieved by changing the operating mode of the nitrifying system.

Zero sludge discharge as the sludge age can be very long, thus greatly improving the degradation efficiency of refractory organic matter, reactor in high volume load, low sludge load, long sludge age operation, the remaining sludge yield is very low, because sludge age can be infinite long, in theory, zero sludge discharge can be achieved.

The Automatic Control System realizes the PLC control, the operation management is convenient.
