Claim 9:
10. The method according to claim 6, wherein a stirring speed of the magnetic stirrer is controlled at 400 rpm to 800 rpm to increase a speed of the evaporation of the wastewater; the temperature of the cooling wall surface is adjusted according to a concentration of the wastewater treated, and the temperature is controlled at 2° C. to 8° C., the temperature and the pressure are controlled to be above a hydrate phase equilibrium curve; and the gaseous hydrate former and the water vapor formed during the evaporation form the hydrate crystal on the cooling wall surface to promote the continuous evaporation of the wastewater in the wastewater evaporation zone.
