Abstract

This invention relates to the field of wastewater treatment technology, and specifically discloses an SV 30 The detection method and sampling detection device include an automatic sampling mechanism, which includes a mounting frame. A sampling component is installed at the end of the mounting frame and is located inside an activated sludge tank (including an aeration tank and an anaerobic tank, the same below). The sampling component is equipped with a sampling container. A sample detection mechanism includes a detection chamber for containing the sample, and a camera component for video acquisition is installed inside the detection chamber. A transfer component is used to move the sampling container from the sampling component to the detection chamber. It also includes a cleaning component. By replacing manual labor with mechanical methods, manual sampling errors can be effectively reduced, ensuring consistent sampling depths across multiple samples. Furthermore, by installing this device on multiple activated sludge tanks, the burden of manual sampling and sampling errors caused by manual sampling are avoided.
