摘要： Provided is a wastewater treatment system. The wastewater treatment system includes an equalization (EQ) tank which receives contaminated wastewater having a high nutrient content from a plant, a dissolved air flotation (DAF) system and an on-site oxygen generation system which provides gas phase oxygen to the wastewater treated in the equalization (EQ) tank and/or the dissolved air flotation (DAF) system. The dissolved air flotation system includes at least one air dissolved air flotation vessel which may house an aerator grid assembly having a perforated lateral diffuser and optionally, a primary aerator assembly.
