Name： polyformaldehyde wastewater treatment project of CNOOC Tianye Chemical
Project name: polyformaldehyde wastewater treatment project of CNOOC Tianye Chemical
Project scale: 2500 m3/d
Commissioning date: Oct, 2007
Treatment process: Anaerobic + aerobic
Project overview: The formaldehyde wastewater produced by polyformaldehyde production owns high organic concentration, complex organic compounds and strong toxicities, which will cause impact on biological treatment. Therefore, these factors should be fully taken into account in process design. Based on our company’s successful experience on formaldehyde wastewater treatment of Yuntianhua group, BODA adopts the technology of UASB reactor+ aerobic treatment. As long as control some key technical parameters well in the process, and the water can meet the requirements of emission standard or water recycling standard.
