Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment storage devices, in particular to a storage device for tin stripping wastewater treatment. Background Art

[0002] Tin stripping wastewater refers to wastewater containing toxic and harmful substances such as lead, cyanide, acid, and alkali generated from industries such as electroplating and printed circuit boards. It is characterized by high concentration, high toxicity, and high volatility. If discharged at will, it will seriously pollute the environment and threaten ecological security and human health. When the tin stripping wastewater is harmlessly treated, a storage device needs to be used for temporary storage. At present, sedimentation tanks are generally used on the market for temporary storage of tin stripping wastewater. Although sedimentation tanks can achieve the function of storing and precipitating tin stripping wastewater, there are still certain problems when using it. For example, when the traditional sedimentation tank storage device precipitates the tin stripping wastewater, a large amount of tin stripping mud will be generated. These tin stripping muds are precipitated at the bottom of the sedimentation tank. The traditional sedimentation tank lacks a structure that can quickly clean the precipitated sludge. When cleaning the precipitated sludge, the staff is very tired. At the same time, when the tin stripping wastewater is stored in the sedimentation tank, the sedimentation tank lacks a structure to purify the waste gas emitted from the tin stripping wastewater. The waste gas generated in the tin stripping wastewater will be discharged into the atmosphere, which is easy to cause certain pollution to the atmospheric environment. Utility Model Content
