Summary of Doctoral thesis Chemical engineering: Study on internal electrolysis combine with AAO-MPPR to treat TNT wastewater

This dissertation focuses on establishing the process of manufacturing bimetallic Fe / Cu internal electrolysis nanomaterial, thereby studying some characteristics correlation between corrosive line and TNT decomposition kinetics and time. Setting and optimizing the internal electrolysis process by bimetal Fe / Cu nanomaterials combined with biological method A2O-MBBR (moving bed Biological reactor) to treat TNT wastewater at laboratory scale and Pilot scale at the scene. | MINISTRY OF EDUCATION VIETNAM ACADEMY OF AND TRAINING SCIENCE AND TECHNOLOGY GRADUATE UNIVERSITY OF SCIENCE AND TECHNOLOGY VU DUY NHAN STUDY ON INTERNAL ELECTROLYSIS COMBINE WITH AAO-MBBR TO TREAT TNT WASTEWATER Speciality Chemical Engineering Code 9 52 03 01 PhD DISSERTATION SUMMARY ON CHEMICAL ENGINEERING Ha Noi - 2020 The work was completed at Vietnam Academy of Science and Technology Science instructor 1.

Background 2 4 6 trinitrotoluene TNT is a chemical widely used in defense and economy. The explosive manufacturing industry discharges a large amount of wastewater containing toxic chemicals such as TNT. In fact about 50 years after World War II in places where gunpowder factories were built large amounts of TNT and their isomers were found in soil and water environments 1 2 21 . This proves that TNT is capable of long-term survival in nature or in other words TNT is difficult to biodegrade. In our country besides the factories is producing ammunition explosives and launchers in the defense industry there are still a large amount of wastewater containing TNT which needs to be treated in warehouses for repairing and collecting ammunition. The commonly methods are used to treat wastewater containing TNT including physical method adsorption by activated carbon electrolysis chemical method Fenton UV - Fenton internal electrolysis biological method aerobic activated sludge MBBR UASB MBR plants enzymes white rot fungi . These measures may be used independent or combination .
