After starting up for 21 d， the IC anaerobic reactor reached the design loading and could treat OCC wastewater for 15 000 m³/d with total COD_Cr for 50 000 kg/d. The COD_Cr removal rate was 72%~86%， and the VFA of reactor outlet water remained 30~110 mg/L， indicating the new IC anaerobic reactor can improve efficiency in a short time.]]> 2024/8/26 18:52:09 LI Xionglin,WEI Qingwei 10true 2024/4/22 15:39:26 WANG Hui,MA Xiaoqing,ZHANG Fengshan,WU Weiran,ZHOU Jingpeng,MA Houyue,LIU Yanshao 9true 6+） comprehensive treatment system that developed by the comprehensive use of self-produced chemicals and existing equipment， the reasons for the generation of Cr⁶⁺ wastewater in the chlorine dioxide workshop and the properties of the wastewater were analysized. Based on the effects of different pH value of reaction pool， reaction temperature， reaction time， and sulfur dosage on the reduction effect of Cr⁶⁺ in wastewater， the optimum reaction conditions of the sulfur dioxide reduction process for removing Cr⁶⁺ were determined， and the reduction effect of Cr⁶⁺ was demonstrated in combination with the actual production data. The results showed that the optimum conditions for the effective removal of Cr⁶⁺ from high concentration chromium-containing wastewater were that pH value of 2~4， reaction temperature of 40~60 ℃， sulfur dosage of 1.4~1.6 times of the theoretical dosage required for the reaction， and reaction time of 40 min. The content of Cr⁶⁺ in the effluent of wastewater from the three shutdowns of chlorine dioxide workshop was lower than 0.005 mg/L， and the content of total chromium was lower than 0.06 mg/L， which were in line with the requirements in the GB 8978—1996， confirming the effectiveness of the treatment of the intermittent Cr⁶⁺ comprehensive treatment system.]]> 2024/4/22 15:39:27 XIE Qin,LI Liping,CUI Zhaofeng,PAN Shidao 8true 2024/4/11 18:55:38 GONG Wei,ZHANG Yi 7true 2024/12/23 9:08:01 LI Na,WANG Shaoming,CHEN Xiaochen,WEI Xin 6true 2024/11/22 15:48:52 HAN Chenxiao,JIA Wenling,CHANG Yongsheng,LI Xianzhao,WANG Yi 5true 2024/11/22 15:48:52 JIN Xingming 4true via a data middle office， thereby forming a closed loop of the data value chain throughout the entire lifecycle of engineering projects.]]> 2025/11/25 12:54:55 LIU Gang,NI Zhengqing 3true 3·min) to 5.6 kW/(m³·min)， achieving an energy-saving rate of 29.1%.
