Embodiment 1
[0027] This embodiment provides a biological turntable system with adjustable liquid level, which is composed of a liquid level adjustment storage tank, a hydraulic water level control valve and a biological turntable device, wherein the biological turntable device adopts an electric biological turntable, and the processing scale is 100m 3 / d, raw sewage COD Cr 100-300mg / L, NH 3 -N is 30-50mg / L, design water COD Cr 30-50mg / L, NH 3 -N is 3-5mg / L.
[0028] The front section of the electric biological turntable is equipped with a high-level water pool (that is, a liquid level adjustment storage tank), and the water volume in the high-level water pool meets the needs of liquid level adjustment in the contact reaction tank of the biological turntable. When the biological turntable stops running, the normal water outlet valve of the biological turntable contact reaction tank is closed, the full immersion control water outlet valve (that is, the hydraulic water level control valve...
Embodiment 2
[0032] This embodiment provides a biological turntable system with adjustable liquid level, which is composed of a liquid level adjustment storage tank, a hydraulic water level control valve and a biological turntable device, wherein the biological turntable device adopts a pneumatic biological turntable, and the processing scale is 200m 3 / d, raw sewage COD Cr 100-300mg / L, NH 3 -N is 30-50mg / L, design water COD Cr 30-50mg / L, NH 3 -N is 3-5mg / L.
[0033] The adjustment of the liquid level in the contact reaction tank of the pneumatic biological turntable is realized by increasing the space of the contact reaction tank at the lower part of the biological turntable. When the biological turntable stops running, the normal water outlet valve of the biological turntable contact reaction tank is closed, the full immersion control water outlet valve is opened, and the rotation shaft of the biological turntable and the disc are lowered as a whole, so that the disc is in a fully sub...
