Aldehyde-based surfactants and industrial, commercial and public facility wastewater treatment methods

摘要

Nonionic surfactants having cyclic 1, 3-dioxane and / or 1,3-dioxolane functionalities, which can be irreversibly degraded by reducing the pH of the aqueous solution, are hydrophobic contaminants emulsified from the aqueous stream or other hydrophobic It is useful in various ways in which removal of the material is required. After the surfactant, its aldehydes and polyol components are decomposed, the hydrophobic component is phase separated and can be removed from the aqueous stream by conventional means.
