Abwasser-Sedimentationsanlage

摘要

The sewage sedimentation plant for the separation of sewage solids of sewage fluid (22) in a sedimentation basin (22), comprises an ultrasonic sludge level sensor (26) for determination of the height of the sludge level in the sewage. The sludge level sensor exhibits an ultrasonic head (30), a temperature sensor (32) for determining the wastewater temperature and a liquid-tight housing, and is arranged in the sewage above the ground of the sedimentation basin. The temperature sensor is connected with the inside of the housing in heat conducting manner. The sewage sedimentation plant for the separation of sewage solids of sewage fluid (22) in a sedimentation basin (22), comprises an ultrasonic sludge level sensor (26) for determination of the height of the sludge level in the sewage. The sludge level sensor exhibits an ultrasonic head (30), a temperature sensor (32) for determining the wastewater temperature and a liquid-tight housing, and is arranged in the sewage above the ground of the sedimentation basin. The temperature sensor is connected with the inside of the housing in heat conducting manner. An evaluation mechanism is intended, which corrects the distance values emitted by the ultrasonic head with the sewage temperature determined by the temperature sensor. Independent claims are included for: (1) an ultrasonic sludge level sensor for determination of the height of the sludge level in the sewage; and (2) procedure for the determination of the sludge level distance of an ultrasonic head.
