Device and method for treating sewage and wastewater by humidity-difference evaporation method

The invention provides a device and a method for treating sewage and wastewater by a humidity difference evaporation method. The sewage and wastewater treatment device comprises a shell, a soaking evaporation assembly arranged in the shell, a water distribution assembly arranged above the soaking evaporation assembly, and a collecting water tank laid at the bottom of the shell, wherein the soakingevaporation assembly is arranged on the periphery of the interior of the shell, an airflow channel is defined by the soaking evaporation assembly in the center of the shell, a gas treatment chamber and a draught fan chamber are sequentially arranged above the airflow channel, and the upper portion of the draught fan chamber is communicated with the atmosphere. According to the invention, the problems of complex process flow, high costs and high difficulty in sewage and wastewater treatment of domestic sewage, garbage penetrating fluid and industrial wastewater treatment are solved. 本发明提出一种湿差蒸发法污废水处理装置及方法，所述污废水处理装置包括壳
