AI Technical Summary

Problems solved by technology

The biochemical treatment takes a relatively long time, and the high content of alcohol will lead to the inactivation of microorganisms
Coagulation precipitation method, air stripping method, extraction method and adsorption method are commonly used in physical and chemical methods, among which air stripping method and extraction method are suitable for production lines with a certain production scale, and the equipment cost is relatively high; adsorption method is mainly used for low-concentration alcohol-containing For the treatment of wastewater, the most commonly used adsorbent is activated carbon, which has poor processing capacity; and coagulation, for water-soluble alcohols, the effect of existing coagulants is relatively poor, and the alcohol in wastewater is mainly obtained by coagulation. The flocs produced in the sedimentation have the adsorption effect and are removed

Description

technical field [0001] The invention relates to a treatment agent for removing methanol, n-butanol and isobutanol from wastewater in an amino resin workshop, and belongs to the technical field of environmental protection. Background technique [0002] Amino resin refers to a thermosetting resin obtained by polycondensation reaction of compounds containing amino groups and aldehydes (mainly formaldehyde). The amino resin used in coatings must be modified by alcohol to be soluble in organic solvents and have good compatibility and reactivity with the main film-forming resin. Amino resins must be etherified with alcohols before they can be applied to coatings. The alcohols used mainly include methanol, ethanol, isopropanol, n-butanol, isobutanol and octanol. The resin etherified with methanol is still water-soluble, the resin etherified with ethanol is alcohol-soluble, and the resin etherified with butanol has better solubility in organic solvents. The wastewater from the ami...
