Measurement of suspended solids concentration using turbidity sensor and Apparatus for determining the fraction of aerobic granule sludge

摘要

Disclosed by the present invention is a device to measure the concentration of suspended substances using a turbidity sensor and check the fraction of aerobic granule sludge. The gas mask comprises: a sludge accommodating unit into which sludge is introduced from a reactor; a solid liquid separating unit which is installed in the sludge accommodating unit and separates solid and liquid from the sludge flowing into the sludge accommodating unit; a stirring unit which is connected to the sludge accommodating unit, accommodates suspended substances separated from sludge by the solid liquid separating unit, and stirs the accommodated suspended substances; a turbidity measuring unit which is installed in the stirring unit and measures the turbidity value of the suspended materials stirred by the stirring unit; a concentration calculating unit which receives a turbidity value of the suspended substances from the turbidity measuring unit and calculates a concentration value of the suspended substances based on the received turbidity value of the suspended substances; and a fraction calculating unit which receives the concentration value of the suspended substances from the concentration calculating unit and calculates the fraction of the aerobic granule sludge based on the received concentration value of the suspended substances. The present invention can accurately measure and check concentration value of suspended substances and fraction of aerobic granule sludge within a short time.
