Description

Technical Field

[0001] The utility model relates to a monitoring device, in particular to a distributed water quality online monitoring device, belonging to the technical field of sewage treatment. Background Art

[0002] During the sewage purification process at a sewage treatment plant, the dosage is a dynamically changing quantity that varies with water quality. The accuracy of the dosage during sewage treatment affects whether the water quality of the water plant meets standards and indirectly affects the cost of sewage treatment. For precise control of dosage, the precision dosing system's adjustment of dosage control parameters relies on real-time monitoring of the water quality parameters in the sewage tank. This is especially true for large-volume sewage treatment tanks, where comprehensive water quality testing is required to truly reflect the actual water quality status in the tank. Traditional monitoring methods, which test the water inlet and outlet separately, cannot accurately grasp the specific water quality status in the tank.

[0003] Among them, the "distributed online monitoring sensor system device for water quality in a large-volume sewage sedimentation tank" disclosed in application number "202222459013.8" "comprises four floats, which are connected by positioning rods, and the surface of the connecting rod is fixedly connected to a waterproof equipment box, and the interior of the waterproof equipment box is provided with a data acquisition and remote transmission module, a large-capacity battery and an antenna, and the bottom of the waterproof equipment box is fixedly connected to a cable, and sensors are evenly installed on the surface of the cable, and the bottom end of the cable is fixedly connected to a sinker." In this utility model, accurate monitoring of water quality in large-volume water tanks is achieved, and the true state of water quality in large-volume water tanks is grasped online in real time, ensuring accurate dosing and improving dosing efficiency, which is beneficial for sewage treatment companies to improve economic benefits and save manpower and material costs.
