Treatment system for binaphthol wastewater containing sodium sulfate salt and sodium sulfite salt

The utility model relates to the technical field of treatment of binaphthol wastewater containing sodium sulfate salt and sodium sulfite salt, in particular to a treatment system for binaphthol wastewater containing sodium sulfate salt and sodium sulfite salt. According to the treatment system for the binaphthol wastewater containing the sodium sulfate salt and the sodium sulfite salt, disclosed by the utility model, sodium naphthalene sulfonate can be recycled firstly through combination of an evaporation process and a cooling process, and then high-concentration filtrate can be discharged out of the system and can be recycled while sodium sulfate decahydrate crystals are formed through re-freezing; and sodium sulfite and sodium sulfate can be separated, and then sodium sulfate decahydrate crystals are subjected to hot melting, resin adsorption and evaporation, so that pure sodium sulfate can be obtained, and the evaporation efficiency is high. 本实用新型涉及含硫酸钠盐和亚硫酸钠盐二萘酚废水处理技术领域，尤其是一种含硫酸钠盐和亚硫酸钠盐二萘酚废水处理系统，本实用新型的含硫
