Description

technical field [0001] The invention relates to the technical field of intelligent monitoring equipment, in particular to an ultrasonic sludge concentration online monitoring device. Background technique [0002] Sludge 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...

Problems solved by technology

[0008] At present, the measurement of MLSS at home and abroad still adopts the time-consuming and laborious gravimetric analysis method, which often takes several hours to detect the results

The optical turbidity detection head imported from abroad is more expensive and has low sensitivity. It can only roughly judge MLSS, and its error is huge. In addition, photoelectric colorimetry can only detect a single indicator of MLSS

In addition, a relatively complete set of automatic monitoring routes for SV and SVI has not been formed at home and abroad. The monitoring of these two indicators is carried out manually, so the processing process of continuous operation day and night cannot achieve high efficiency. Three shifts a day The waste of human resources caused the automatic collection of information to be untimely, resulting in the backwardness of the sewage treatment automation mechanism
