Description

Technical Field

[0001] The utility model relates to the technical field of salt wastewater treatment, in particular to a treatment tank for saline wastewater. Background Technique

[0002] Chemical wastewater contains high concentrations of salts and other chemical substances. If directly discharged, it will damage the environment. At present, there are feasible and reasonable methods for treating ordinary wastewater. However, in some special process chains, the high-concentration saline wastewater generated has relatively high treatment costs and transportation costs. Many enterprises still adopt methods such as random discharge or mixed discharge, seriously polluting the ecological water bodies.

[0003] In industrial production processes such as chemical engineering, electroplating, metal smelting, and electronics, a large amount of wastewater containing heavy metals will inevitably be generated. These heavy metals usually have high toxicity and are difficult to decompose naturally. Therefore, once directly discharged into the natural water environment without treatment, it will pose a serious threat to the ecological system and human health. More importantly, this direct discharge method also means that we lose the opportunity to effectively recycle and reuse the precious heavy metal resources therein, which is not only a waste of natural resources but also an ignorance of environmental sustainable development.
