Scope: This standard specifies the classification and nomenclature, structural type, basic parameters, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, etc. of dissolved air flotation filtration water purifiers. This standard is applicable to wastewater purification treatment based on air flotation and filtration processes. It is suitable for the treatment of pollutants containing hydrophobicity and hydrophobicity adjusted by chemicals with a specific gravity close to 1. It is also applicable to biological wastewater discharged from various biological treatment equipment. A water purifier that uses a mud film to separate water from water and purify water is hereinafter referred to as a water purifier. This device is suitable for water purification devices with a processing capacity of (5-100)t/h.
