| 1 | Treatment of Enzymolysis Wastewater by Centrifugation- Coagulation- Fenton Reagent Oxidation- Adsorption Process显示文摘[Objective]The study aimed to discuss the optimal conditions for the treatment of enzymolysis wastewater by centrifugation-coagulation-Fenton reagent oxidation-adsorption process.[Method]According to the water-quality characteristics of wastewater from a heparin sodium production factory of Jiangsu Province,enzymolysis wastewater was segregated from intestinal lavage wastewater and treated through centrifugation-coagulation-Fenton reagent oxidation-adsorption process,and the optimal technical parameters were determined.[Result]After enzymolysis wastewater was centrifuged at a speed of 4 000 rpm,0.6 g/L CTS as the coagulant was added to the supernatant.Hereafter,pH of the coagulated effluent was adjusted to 3,and then 1.5%(V/V)H2O2was added to the coagulated effluent;a certain amount of ferrous sulfate(n H2O2∶n FeSO4·7H2O=8∶1)was added to the mixture;the reaction conducted for 30 min,and then solution pH was adjusted to about9.Finally,the oxidized effluent flowed through a resin red until the adsorptive capacity reached 240 BV,and COD of the effluent water was lower than 100 mg/L,meeting the Grade-I standard of Comprehensive Discharge Standard of Sewage(GB8978-1996).[Conclusion]The research could provide a new process for the treatment of enzymolysis wastewater. | Jian Zhai Chunhua Jiang Guoqing Cao Xiuguo Lu | 2013 | Meteorological and Environmental Research2013，4，9： | 3 |
| 2 | Highly Efficient Photoelectrocatalytic Reduction of CO2 to Methanol by a p–n Heterojunction CeO2/CuO/Cu Catalyst显示文摘Photoelectrocatalytic reduction of CO2 to fuels has great potential for reducing anthropogenic CO2 emissions and also lessening our dependence on fossil fuel energy.Herein,we report the successful development of a novel photoelectrocatalytic catalyst for the selective reduction of CO2 to methanol,comprising a copper catalyst modified with flower-like cerium oxide nanoparticles(CeO2 NPs)(a n-type semiconductor)and copper oxide nanoparticles(CuO NPs)(a p-type semiconductor).At an applied potential of−1.0 V(vs SCE)under visible light irradiation,the CeO2 NPs/CuO NPs/Cu catalyst yielded methanol at a rate of 3.44μmol cm^−2 h^−1,which was approximately five times higher than that of a CuO NPs/Cu catalyst(0.67μmol cm^−2 h^−1).The carrier concentration increased by^108 times when the flower-like CeO2 NPs were deposited on the CuO NPs/Cu catalyst,due to synergistic transfer of photoexcited electrons from the conduction band of CuO to that of CeO2,which enhanced both photocatalytic and photoelectrocatalytic CO2 reduction on the CeO2 NPs.The facile migration of photoexcited electrons and holes across the p–n heterojunction that formed between the CeO2 and CuO components was thus critical to excellent light-induced CO2 reduction properties of the CeO2 NPs/CuO NPs/Cu catalyst.Results encourage the wider application of composite semiconductor electrodes in carbon dioxide reduction. | Zhengbin Pan Ershuan Han Jingui Zheng Jing Lu Xiaolin Wang Yanbin Yin Geoffrey INWaterhouse Xiuguo Wang Peiqiang Li | 2020 | Nano-Micro Letters2020，12，2： | 3 |
| 3 | Treatment of Intestinal Lavage Wastewater by Coagulation-ASBR-SBR Process显示文摘[Objective]The study aimed to discuss the optimal conditions for the treatment of intestinal lavage wastewater by coagulation-ASBR-SBR process.[Method]According to the water-quality characteristics of wastewater from a heparin sodium production factory of Jiangsu Province,intestinal lavage wastewater was segregated from enzymolysis wastewater and treated using coagulation-ASBR-SBR process,and the effects of PFS dosage,HRT of ASBR and SBR reactor on the removal rate of COD and NH+4-N were analyzed.[Result]The best dosage of PFS was 0.15 g/L,and the optimal HRT of ASBR reactor was 36 h,while the best HRT of SBR reactor was 15 h.Under the optimal conditions above,the removal rate of COD and NH+4-N reached 99.1%and 97.3%respectively,and the quality of the effluent water could reach the first standard of Comprehensive Discharge Standard of Sewage(GB8978-1996).[Conclusion]The research could provide a new process for the treatment of intestinal lavage wastewater. | Jian Zhai Chunhua Jiang Guoqing Cao Xiuguo Lu | 2013 | Meteorological and Environmental Research2013，4，8： | 2 |

| 5 | Segregation Treatment and Resource Recycling of Enteric Coating and Heparin Sodium Manufacturing Wastewater显示文摘Firstly,the water-quality characteristics of intestinal lavage wastewater and enzymolysis wastewater from the typical heparin sodium productive process were analyzed,and then the segregation treatment was applied in the treatment of enteric coating and heparin sodium manufacturing wastewater. Finally,the treatment of the two kinds of wastewater by different methods were discussed. The results showed that,COD of enzymolysis wastewater treated by centrifugation-coagulation-Fenton reagent oxidation-adsorption process was lower than 100 mg /L,while intestinal lavage wastewater treated by coagulation-ASBR-SBR process could meet the first standard of Comprehensive Discharge Standard of Sewage( GB8978-1996) after one month of continuous operation. | Jiang Chunhua Zhai Jian Cao Guoqing Lu Xiuguo Ling Shulei Zhang Jing | 2014 | Meteorological and Environmental Research2014，5，4： | 0 |
| 6 | Influence of temperature and light gradient on leaf arrangement and geometry in cucumber canopies: Structural phenotyping analysis and modelling显示文摘Accurate structural phenotyping analysis is essential to understand plant architectural adaptation strategy to environment change.The aim of this study was to analyze leaf arrangement and geometry influenced by azimuthally generated light gradient;and to simulate static and heterogeneous cucumber canopies using regression equations by considering more geometric parameters.Three continuous measurements of structural organ parameters were obtained to fit the organ initiation and expansion curves.Four measurements with three density treatments were obtained to validate model accuracy.To describe leaf distribution and orientation characteristics in more detail,azimuth and elevation models were introduced into canopy structure modelling.Leaf distribution frequency was simulated based on leaf area index and solar elevation angle while leaf elevation was simulated based on leaf azimuth and acropetal phytomer number.This study provides an important basis for structural phenotyping analysis of cucumber canopy,which is essential for more accurate functional-structural modelling in the future. | Tingting Qian Xiuguo Zheng Xinyu Guo Weiliang Wen Juan Yang Shenglian Lu | 2019 | Information Processing in Agriculture2019，6，2： | 0 |
