Anaerob nedbrytning av TNT : Ett bioreaktorförsök på Vingåkersverken

Lindmark, Johan January 2008 (has links)
A bioslurry reactor was built for the bioremediation of TNT contaminated waste from the demilitarization industry. The field test was conducted at Vingåkersverken in Vingåker, Sweden, to see if results from laboratory studies could be repeated in a full scale reactor. The goal of the project was to optimize the reactor to such a degree that it could be used to handle the waste produced at Vingåkersverken and also that this technique could be applied for remediation of contaminated soils. Unfortunately the samples taken during the full scale field test were destroyed by the shipping company and no analysis was possible. A later attempt by the Biorex research group has also been unsuccessful to reduce the amount of TNT using the bioreactor. How are we going to reach the results from the laboratory studies? The work continues.

No. of bitstreams: 1 tese_7769_Bruno Cancian de Araujo.pdf: 14411584 bytes, checksum: b064981d037df6effd664835b257b5d9 (MD5) Previous issue date: 2014-05-30 / A primeira análise cladística supraespecífica de Hybothoracini é apresentada. São testados 21 gêneros e 92 UTOs. Com base em 91 caracteres morfológicos, foram realizadas 11 análises de parcimônia, sendo uma com pesagem igual e 10 com pesagem implícita para valores de k entre 1 e 300. As análises de pesagem igual resultaram em quatro árvores igualmente parcimoniosas sob as quais foi gerada uma árvore de consenso estrito. As 10 análises de pesagem implícita geraram uma árvore cada, com basicamente três topologias distintas, para k variando entre 1 e 10, entre 16 e 50, e entre 100 e 300. Hybothoracini é monofilético em todas as análises e inclui Tropimeris e Zavoya como proposto por Wijesekara (1997). Os seguintes gêneros são mantidos: Hastius Schmitz, Hybothorax Ratzeburg, Irichohalticella, Cameron, Lasiochalcidia Masi, Nearretocera Girault, Nipponochalcidia Habu, Notaspidiella Bouček, Notaspidium Dalla Torre, Proconura Dodd, Psilochalcis Kieffer, Schwarzella Ashmead, Solenochalcidia Steffan, Steninvreia Bouček, Xenarretocera Girault, Tropimeris Steffan. São propostas nove sinonímias genéricas, a citar: Hayatiella Narendran, sin. nov. e Neohybothorax Nikol'skaya, sin. nov. sob Hybothorax Ratzeburg; Bucekia Steffan, sin. nov. e Indoinvreia Roy & Farooqi, sin. nov. sob Lasiochalcidia Masi; Halsteadium Bouček, sin. nov. sob Notaspidium Dalla Torre; Cephalochalcidia Nikolskaya, sin. nov., Euchalcidiella Masi, sin. nov., Hyperchalcidia Steffan, sin. nov., Peltochalcidia Steffan, sin. nov. sob Xenarretocera Girault.

Peroxone groundwater treatment of explosive contaminants demonstration and evaluation

McCrea, Michael V. 03 1900 (has links)
The purpose of this thesis is to evaluate the performance and cost effectiveness of a Peroxone Groundwater Treatment Plant (PGTP) designed and operated by Montgomery Watson, in support of the Defense Evaluation Support Agency's independent analysis for the United States Army Environmental Center (USAEC). Many Department of Defense installations have sites that contain groundwater contaminated with explosive materials. Primary methods for the removal of explosive materials involve the use of Granular Activated Carbon (GAC). This process, however, requires additional waste disposal and treatment of explosive laden GAC, thereby incurring additional costs. An alternate method for the treatment of contaminated groundwater involves the use of hydrogen peroxide (H2O2) in conjunction with ozone (03). This method is referred to as the Peroxone oxidation process. A demonstration of the PGTP was conducted from 19 August to 8 November, 1996, at Cornhusker Army Ammunition Plant (CAAP), Grand Island, Nebraska using a small scale version with a maximum flow rate of 25 gallons per minute. The explosive contaminants analyzed during the demonstration include 2,4,6-Trinitrotoluene (TNT), 1,3,5-Trinitrobenzene (TNB), 1,3,5-Triazine (RDX), and Total Nitrobodies. Peroxone cost effectiveness was evaluated using a 30 year life cycle cost comparison to GAC and Ultraviolet/Ozone processes
