Sedimentation tanks are usually widely used in sewage treatment plants, industrial wastewater treatment plants, water plants and other occasions. It is a very important water treatment equipment. When the existing sedimentation tanks for heavy metal wastewater treatment are in use, different types of heavy metal-containing wastewaters produced by different types of industries are different. The wastewater may contain a large odor and have certain corrosiveness and toxicity. Direct discharge not only endangers the health of on-site workers but also pollutes the environment. At the same time, the sedimentation tank has strong sealing properties, and it is not convenient for users to sample the wastewater inside the tank during use, and it is impossible to know the sedimentation effect.
