| titleOfInvention | Separation and purification method of industrial high-salinity wastewater |
| abstract | The invention belongs to the technical field of industrial high-salinity wastewater treatment, and particularly relates to a method for separating and purifying industrial high-salinity wastewater, which comprises the following steps: carrying out primary evaporation concentration on the wastewater with high salt content to form wastewater with higher salt content; carrying out low-temperature treatment on the obtained wastewater to reduce the temperature of the wastewater to 1.5-2 ℃, separating out sodium sulfate in the wastewater, and separating the sodium sulfate from the wastewater; leading the rest wastewater into an industrial high-salt wastewater separation and purification device for salt separation and purification so as to enable salt to be gathered on the ball body; after the wastewater is separated and purified, reserving and storing the separated and purified salt, and discharging the wastewater; the invention separates sodium sulfate from the wastewater by carrying out preliminary evaporation concentration and low-temperature treatment on the wastewater; salt in the waste water is automatically separated out and separated out through the industrial high-salt waste water separation and purification device, the separation effect is good, the purification efficiency is high, and the salt and the waste water can be effectively separated. |
