300m3/D Integrated hotel wastewater treatment system

Integrated domestic sewage treatment system

Project: 300m3/D Integrated hotel wastewater treatment system

Project Introduction: The system is a hotel wastewater treatment and reuse system. The wastewater is divided into two parts: kitchen oily wastewater and domestic sewage. Oily wastewater is treated by air flotation and mixed with domestic sewage into the integrated treatment system. After treatment, the wastewater reaches the first class discharge standard, and then enters the reverse osmosis (RO) system for advanced treatment and reuse. Influent water quality: COD: 368ppm, BOD: 146ppm, SS: 312ppm, ammonia nitrogen: 28ppm

Process flow of integrated domestic sewage treatment system:

Conclusion: After being treated by the integrated sewage treatment system, the quality of the produced water is COD: 39ppm, BOD: 26ppm, SS: 4.2ppm, ammonia nitrogen: 5.4ppm, fully meeting the first-class discharge standard. After the preliminary treatment of sewage, it enters the RO system for advanced treatment. RO produced water can be used for irrigation, car washing, laundry, air conditioning circulating water replenishment water and other purposes. Concentrated water returns to the regulating tank, basically achieving zero discharge of sewage. It has achieved good social and environmental benefits.
