| titleOfInvention | Near-zero emission treatment system and process for ternary precursor material production wastewater |
| abstract | The invention discloses a near-zero emission treatment system and process for ternary precursor production wastewater. The ammonia water generated after the ammonia gas volatilized and escaped from the waste water heating and heavy metal deposition clarification process is recovered is reused for production, water vapor and ammonia gas are generated in the MVR primary evaporation concentration separation process, the ammonia gas is recovered for producing the ammonia water while condensed water is recovered, the integration technology for simultaneously recovering the water and the ammonia replaces the existing steam stripping ammonia recovery technology with high energy consumption in a single process, the treatment process is reduced, the operation cost is reduced, and the secondary MVR evaporation crystallization technology is adopted for recovering resource anhydrous sodium sulphate and the condensed water. The method has the advantages of protecting the environment, reducing the discharge of the wastewater with high salt content, reducing the wastewater recycling treatment cost, changing waste into valuable, generating economic benefit and realizing the near-zero discharge treatment of the wastewater. |
