The paper built a wastewater evaporative concentrating and separation experimental device，and conducted
experiments on the solution and wastewater at different temperature and pH conditions． According to the experimental data，a
comprehensive summary of the thermodynamic properties and physical and chemical characteristics of wastewater were gained．
The results showed that: The boiling point elevation of organic wastewater with high salinity increased with evaporative
concentration ratio rised; when TDS reached to saturation concentration，the high amplitude of increasing boiling point
elevation dipped; during the evaporation continued to advance，the salt precipitated out and boiling point elevation value went
stabilized; as the evaporation temperature and the solution pH increasing，at the same evaporative concentration ratio，boiling
point elevation and the organics rejection ratio of evaporative concentration in organic wastewater with high salinity increased．
