Comparison of efficiency optimization for different media used in anaerobic hydrolysis

摘要

Biological contact oxidation process in environmental wastewater treatment is accepted extensively by everyone because of its prominent effect, stabile circulating and convenient operation, which key technique—biofilm carrier (called media) is paid attention to by the majority of experts and customers. We compared the potencies of several media, following "Biosorption—Anaerobic Hydrolysis—Aerobic Treatment—Efficient Clarifier" process and according to 300,000 t/d capability of Xiaoshan Qiantang Wastewater Treatment Co., Ltd. (Hangzhou)—high density printing and dyeing wastewater, "TB/TA, TB/TH natural oscillating media" applied in the process of anaerobic hydrolysis treating chemical wastewater. These results play an important role in media type selection and actual engineering, especially in application in complicated and varied components printing and dying wastewater and chemical wastewater treatment.
