Decontamination process Industrial wastewater treatment method using byproduct

摘要

As a method of treating industrial wastewater, it is a byproduct of the decontamination process. It is a process by which a chemical is produced from a chemical salt manufacturing process using an ion exchange membrane method and a multi-effect evaporation method, The wastewater generated during the storage, storage, or harvesting of wastewater generated during the storage of the jarring, mechanic salt, sun salt, refined salt, etc. is refined by evaporation, filtration or filtration. It is then mixed with an alkaline agent such as Ca (OH) It is recommended to use industrial wastewater such as dyeing wastewater, dye wastewater, leather wastewater, printing wastewater, paper wastewater, food wastewater, pulp wastewater, chemical wastewater, etc. (when the wastewater has a pH of 10 or more, an alkaline agent such as Ca (OH) CaCO3 or CaSO4 may be added to the wastewater in order to increase the flocculation effect depending on the wastewater property) Solution and, after coagulation to precipitate, or filtering the precipitate solution color, haze, suspended solids, sulfur, organic substances such as industrial waste water treatment method characterized in that the decontamination process using by-products of the reduction was stirred for water.
