WET AIR OXIDATION TECHNOLOGY FOR WASTEWATER TREATMENT

摘要

Siemens Water Technologies (www.siemens.com/ industry-solutions) will provide Zimpro wet air oxidation technology to treat wastewater at Sinopec's Zhenhai and Tianjin ethylene plant projects in the Zhenhai District, Ningbo, Zhejiang Province, and in Tianjin, China. The systems will be used to treat sulphidic spent caustic wastewater streams generated in the production of ethylene. The energy efficient wet air oxidation systems will destroy odorous sulphide pollutants and generate a biodegradable effluent that can be discharged to conventional biological wastewater treatment. The Zhenhai system will treat approximately 18.2 m3/h of wastewater; the Tianjin system will treat 14.5 m3/h.
