Experiment Research on Industrial Saline Wastewater Treatment Base on Evaporative Concentration Method

For rational utilization of industrial wastewater containing salt, this paper puts forward a method to evaporate and concentrate salty water by applicating no padding evaporative cooling tower. This paper has established a testing bench of evaporation and concentration of salt-containing wastewater and fresh water recovery system. The actual operating characteristic of the testing bench is also tested. Tests showed that evaporated quantity of water of the system ranged from 1.8 to 2.2t/h under the conditions of salt water inlet temperature between 30°C and 40°C.It proves that the proposed salt-containing wastewater treatment is feasible.
