Case
High-salinity wastewater three-effect evaporation crystallization treatment project
****** Chemical Co., Ltd. mainly produces efficient and low-toxicity agricultural fungicides, especially the agricultural fungicide Kexun Dan, and plans to become the largest domestic production base for Kexun Dan agricultural fungicides and a high-end rubber carbon black production enterprise. In addition, the company also produces pesticides and pesticide intermediates, including an annual output of 600 tons of 2,2-dimethyl-5-(4-chlorobenzyl) cyclopentanone, an annual output of 500 tons of trimethyl bromosulfone, and an annual output of 500 tons of leaf fungicide. This project handles wastewater containing mixed salts, high COD, and high concentration, with a designed evaporation capacity of 4.0t/h, a designed boiling point elevation of about 14℃, and recovers mixed salts through evaporation crystallization. The process design includes three-effect forced circulation evaporation crystallization. High-salinity wastewater is treated by evaporation desalination, and the condensed water is sent to the sewage station, while the mother liquor is dried, and the crystallized salt is outsourced. The project has been accepted, and customer satisfaction is relatively high.
