| titleOfInvention | High salt-containing deacidification wastewater resource utilization system |
| abstract | The utility model discloses a resource utilization system for deacidification wastewater with high salt content, which comprises a homogenizing tank, a first reaction tank, a second reaction tank, a sedimentation tank, a concentration tank, an ultrafiltration device, an ultrafiltration water-producing tank, a nanofiltration device, a nanofiltration water-producing tank, a reverse osmosis device, a triple-effect evaporation unit, a nanofiltration concentrated solution tank and a freezing crystallization device which are sequentially connected with each other; CaCl is arranged above the first reaction tank 2 A chemical adding device is arranged above the second reaction tankNa 2 CO 3 The dosing device is arranged above the ultrafiltration water production pool. The utility model can react with the agent and cooperate with the membrane treatment devices with different levels of precision to remove SO in the deacidification wastewater 4 2‑ And Cl ‑ Effective separation is carried out to finally obtain the Na with higher purity 2 SO 4 And NaCl, so that effective recovery and resource utilization of salts in the deacidification wastewater can be realized, the generation amount of solid waste is reduced, and the energy-saving and emission-reducing degree is improved. |
