Description

technical field [0001] The invention belongs to the field of automatic detection, and in particular relates to a sludge concentration monitoring system based on a cloud platform. Background technique [0002] Suspension concentration is an important process control parameter in the operation of water supply plants and sewage plants. The traditional artificial sampling chemical drying analysis method has low efficiency and long measurement cycle, and it is difficult to play a role in process control. To this end, people have developed sludge concentration measuring instruments based on optical methods, ray methods, vibration methods, and ultrasonic methods. Especially, ultrasonic attenuation method sludge concentration measuring instruments are widely used in the field of sewage treatment. Due to the large changes in environmental conditions in practical applications and the wide range of temperature changes in the measured sludge, it is difficult for the existing sludge con...
