Multi-section sampler for sewage settling tank

The utility model relates to a multi-section sampler for a sewage settling tank. The multi-section sampler comprises a sampling drum, a sampling hole stopper, a pulling ring and an anti-static measuring pulling rope. The multi-section sampler is characterized in that the sampling drum consists of three (or more) independent sampling cavities which are isolated mutually; the side surfaces of the upper end and the bottom part of each sampling cavity are respectively provided with an independent sampling hole and a liquid discharging valve. The multi-section sampler has the advantages that in use, the sampler is put into the settling tank, and three (or more) liquid samples at different depths of the settling tank can be extracted one time.
