| titleOfInvention | A method for treating high-salt organic wastewater |
| abstract | The invention discloses a method for treating high-salt organic waste water, which combines concentration and salt extraction with biochemical treatment to remove inorganic salts and organic matter step by step, so as to achieve standard discharge of waste water. The specific technical steps are: adding a dehydrating agent to the wastewater heated to 40-80°C until the wastewater is saturated, cooling the saturated wastewater to 5-5°C, precipitating mixed salt crystals, and centrifuging the crystallization wastewater to obtain mixed salt crystals and high The organic matter concentrates the mother liquor, the mixed salt crystals are washed to obtain dehydrating agent hydrate crystals, the washing mother liquor is evaporated and concentrated to extract the salt, the dehydrating agent hydrate crystals are heated to 95-150 ° C for transcrystallization and dehydration to obtain regenerated dehydrating agent and condensed water, and the high organic matter concentrated mother liquor is subjected to Concentrating and extracting salt for 3-5 times to obtain a concentrated mother liquor containing high salt organic matter, and diluting the concentrated mother liquor containing high salt organic matter with condensed water for biochemical treatment to obtain standard wastewater. The process conditions of the invention are mild, the dehydrating agent can be recycled, the energy consumption is low, the treatment cost is reduced, and the wastewater discharge standard is met. |
