The diversity and richness of microorganisms in ICPB system increased， and the dominant bacteria degrading aromatic compounds increased significantly.]]> 2023/8/31 0:00:00 TIAN Qingwen,ZHU Yawei,FANG Guigan,PAN Aixiang,GUO Wenliang,YIN Hang,SHI Yingqiao,LIANG Fangmin 3true 2S₂O₈ concentration on the TAP system was first investigated to achieve the optimal system. This was followed by a discussion of the effect of inorganic cations and anions presence in the system on the TAP system. Then an elaborate analysis of the oxidation mechanism of the TAP system and the possible degradation pathways of the pollutants was carried out. Finally application of the TAP system was used to the actual wastewater. The results showed that the COD_Cr of the simulated wastewater was degraded by 84.2% within 360 min under the optimized conditions of 70 ℃ and Na₂S₂O₈ 16 mmol/L. The efficiency of SO4-· radical based TAP system was less affected by inorganic ions. In addition， the main active substances in the TAP system were the ∙OH and SO4-· radicals， both of which plaied a major role in the degradation of organic pollutants in simulated wastewater. Besides， other reactive radicals plaied a supporting role in the degradation of pollutants， such as ·O2-， ¹O₂ and organic radicals. Then， the simulated organic pollutants were converted into small molecule compounds that ere eventually mineralised into CO₂ and H₂O by speculating on the possible degradation pathway. The TAP system was applied to the treatment of biochemical treatment effluent of actual wastewater and it was found that the COD_Cr and colority of the treated effluent met the GB 3544—2008 discharge standard at 70 ℃ and under acidic conditions.]]> 2023/8/31 0:00:00 NONG Guoyou,XIE Hongjie,HUANG Wenyu,ZHU Hongxiang,XIONG Jianhua,LU Lihai 2true Cr and ammonia nitrogen decreased 63.0% and 81.8%， respectively. The emission intensities of water pollutants of paper industry in Nanning， Liuzhou， and Guigang were higher than the average level of Guangxi. The emission intensities of small and medium-sized enterprises were significantly higher than that of large enterprises in Guangxi paper industry. The production process of paper industry still had great potential for improvement. The reduction of water pollutants should be carried out from two aspects： total amount control and intensity control.]]> 2023/8/31 0:00:00 FAN Bolun,GUO Shiqi,BU Xiuqin,HUANG Xiannan 1true
