Description

Technical Field

[0002] The wastewater evaporator is based on the principle of evaporation, concentration and crystallization, aiming at the high salt and high concentration characteristics of chemical organic wastewater. It adopts multi-effect vacuum evaporation to concentrate and crystallize organic wastewater. After separating the salt in the concentrate, it is recovered through the salt collector, and the concentrate is dried, recovered or incinerated. The condensed water after evaporation is generally treated by subsequent biochemical treatment to achieve the wastewater discharge standard.

Therefore, we propose a high-salinity industrial wastewater treatment device. Utility Model Content
