Effect of preozonation on improvement of settleability of solid in highly concentrated organic wastewater of Japanese wh
Abstract： Solid-liquid separation of the wastewater is very difficult because of high viscosity and high SSconcentration. In this study, the effectiveness of preozonation on improving the settleability of the solids in wheatand sweet potato wastewaters was investigated using a bench-scale system and pilot treatment system respectively.Results showed that solid-liquid separation in the wheat wastewater was greatly improved by the decanter in thesystem(SS reduction from 24100 mg/L to 100 mg/L). However, preozonation practice did not show a significanteffect on solid-liquid separation of the sweet potato wastewater. Effect of preozonation on solid-liquid separationbetween wheat and sweet potato wastewater showed different. 作 者： Masafumi Tateda Masanori Fujita Michihiko Ike QUI Yen-feng Satoru Kokubo 作者单位： Masafumi Tateda(College of Environmental Technology, Toyama Prefectural University, Japan)Masanori Fujita,Michihiko Ike(Department of Environmental Engineering, Graduate School of Engineering, Osaka University, Japan)
