Abstract: The efficient treatment of toilet black water and yellow water was an essential component of current wastewater treatment. According to the research process and treatment mode， the black water treatment technology could be divided into centralized black water treatment technology， dispersed black water treatment technology， emerging black water treatment technology and black water resource technologies. Most technologies， including biological， physicochemical， and other treatment methods， were focused on the treatment and recovery of nutrients due to the high concentration of nitrogen and phosphorus resources in source-separated yellow water. The different technical characteristics， principles， research status and application cases of black water and yellow water were summarized. And the corresponding development directions， such as source separation technology development， micro-pollutants advanced treatment and high-quality resource recovery were proposed.

Key words: toilet, black water, yellow water, resource recovery
