I happened to be working on a project of high-salt wastewater recently. Wastewater with high salinity and high pollution index can not be simple, and the cost will be high. Of course, this is on the premise of seriously treating wastewater. Solve the technical means of pollutants and high salt affecting incineration, biochemistry and materialization. Measures such as reverse osmosis, electrodialysis, evaporation and crystallization will be affected by salt and pollutants. At the same time, there is basically no integration process with good performance and cost. Cod caused by o-chlorobenzaldehyde can hardly be solved by conventional sewage treatment (this solution refers to removal), especially under the influence of high salt. But I can consider transferring, because I don't know much about the surrounding properties of o-chlorobenzaldehyde, which may not be the best. If you have experimental conditions, you can try it yourself and determine a better process. Solid-liquid-gas phase separation can be considered. According to water, o-chlorobenzaldehyde and sodium sulfate, solid-water-gas separation is carried out according to their melting points and boiling points. O-chlorobenzaldehyde and sodium sulfate can also be recovered to reduce the comprehensive cost. Except sodium sulfate, mvr process is relatively mature at present, and its cost is about 30 ~ 60 yuan/ton. If the wastewater discharge does not meet the requirements of salt content index, it will be discharged directly without considering recycling. We can only make a fuss about the transfer reduction of o-chlorobenzaldehyde.
