2. Description of the Related Art Up to now, a floor cleaning agent containing an alkylphenol ethoxylate has been widely used because of its good detergency. However, such a floor cleaning agent is used to remove oily pollutants and the like. In the wastewater treatment after washing the object to be washed, it has become clear that some of the aromatic components are environmental pollutants such as endocrine disruptors, so the discharge amount should be strictly regulated by the national wastewater standards. Moreover, even if such wastewater is diluted, chemical oxygen demand (COD), n-hexane extract substance content, hydrogen ion concentration (hydrogen index), etc. do not meet the national wastewater standards. There was a problem that a wastewater treatment process was required and complicated work was inevitable.
