Treatment plan for 100MT/D high-salt wastewater
Thread Content
There is a new product that generates high-salinity wastewater (sodium chloride) with a concentration of 20% per day, and its COD level is around 8,000–10,000; the main organic components in this wastewater are low-molecular-weight alcohols and aldehydes. The production capacity is 100 MT/D. The plan currently being considered by the factory is a multi-effect evaporation approach followed by subsequent treatment. (Considering that the wastewater volume is not particularly large, the evaporators tend to scale, and there are investment cost issues, the use of MVR is not considered.) The goal is to achieve a COD level of less than 100; currently, we know that the COD of the water produced by multi-effect evaporation remains stable between 600 and 800. However, in the post-treatment plan, it is not clear whether biochemical treatment, Fenton oxidation, electrooxidation, or a combination of these methods will be used for the water that evaporates. If you are looking to develop a comprehensive solution, please contact me as well. Furthermore, for such wastewater, it is recommended to carry out oxidation treatment first before sending it to the evaporator, in order to reduce scaling in the evaporator and lower energy consumption. The overall cost will be lower. Is it feasible to do this? I would appreciate your advice. Thank you.

It is a wastewater treatment device for high-salt and high-COD wastewater, featuring low operating costs, low investment requirements, low maintenance costs, and small space consumption; it removes salts and degrades COD. WeChat communication within the station.
A completely new evaporation process: the air-enhanced cyclic evaporation system is quite suitable; it has lower energy consumption than three-effect evaporation, lower investment costs, enables low-temperature evaporation of heat-sensitive substances, and can make use of waste heat.
