Orientador: Liliane Lazzari Albertin / Resumo: A situação de escassez de recursos financeiros destinados ao tratamento e coleta de esgotos municipais, no Brasil, torna essencial a busca por tecnologias de tratamento que priorizem baixos custos de instalação e operação. Além da negligência que existe no tratamento de esgotos, os métodos utilizados, muitas vezes, não são capazes de remover os micropoluentes que estão presentes nos esgotos domésticos. Os micropoluentes podem ser desde fármacos, que são expelidos na urina ou descartados de maneira inadequada, a hormônios naturais ou sintéticos. Esse trabalho consistiu em realizar um processo de polimento do esgoto sanitário da cidade de Ilha Solteira – SP. O sistema de polimento é constituído por dois tanques, onde foi cultivada a macrófita Landoltia punctata. Foi também avaliado e feito a recirculação do efluente, no tratamento de esgoto. Neste sistema de polimento, foram avaliadas as eficiências de tratamento para os parâmetros de DBO, DQO, NT, NO3-, PT e ST. As maiores eficiências de remoção para DBO, DQO, NT, NO3-, PT e ST foram de 66,35%, 59,08%, 26,76%, 28,38%, 6,85% e 40,08%. Outro aspecto avaliado foi a taxa de crescimento da macrófita cultivada em esgoto sanitário. As maiores taxas de crescimento relativo foram de 3,84 e 3,17 g.m-2.d-1 MS. Considerando a presença de desreguladores endócrinos (DEs) no efluente da Estação de Tratamento de Esgoto (ETE) de Ilha Solteira, foi analisado a absorção dos estrógenos 17α-etinilestradiol (EE2) e o estriol (E3) pela macrófita, av...

In addition, the methods used are often not able to remove the micropollutants that are present in domestic sewage. Micropollutants can range from drugs that are expelled in the urine or inappropriately discarded to natural or synthetic hormones. This work consisted of a process to polishing the sanitary sewage of the city of Ilha Solteira - SP. The treatment system consists of two tanks, where the macrophyte Landoltia punctata was grown. In one of the tanks, a recirculation system was performed. In this polishing system, the treatment efficiencies for the BOD, COD, TN, NO3-, TP and ST parameters were evaluated. The highest removal efficiencies for BOD, COD, TN, NO3-, TP and ST were 66,35%, 59,08%, 26,76%, 28,38%, 6,85% and 40,08%. Another aspect evaluated was the growth rate of the macrophyte. The highest relative growth rates were 3.84 and 3.17 g.m-2.d-1 MS. Considering the presence of endocrine disrupters (DEs) in the effluent from the Sewage Treatment Plant (ETE) in Ilha Solteira - SP, 17α-ethinyl estradiol (EE2) and estriol (E3) were analyzed on the plant to evaluate possible risks on the reuse of the biomass. The maximum achieved efficiencies for removal of E3 and EE2 were 83.63% and 83.50%, respectively. The recirculation tank was more effective at removing E3, while the non-r...

Cette thèse présente divers aspects du polissage des eaux usées de galvanoplastie par des zones humides artificielles : analyse de la performance, étude de la configuration et de la mise en œuvre, influence de différentes sources de carbone, évolution du substrat, l'analyse des plantes et des problèmes de conception.Les objectifs de ce travail sont triples: (i) étudier la faisabilité du polissage des effluents de la galvanoplastie, (ii) étudier l'influence des systèmes opérationnels, des plantes, du substrat et de la charge des eaux usées, (iii) comprendre les mécanismes conduisant à une diminution de la charge métallique dans des microcosmes de zones humides construites.Ce travail a fourni de nouvelles informations et élargi les connaissances actuelles sur le traitement des eaux usées industrielles dans les zones humides artificielles. En fait, il s'agit, à notre connaissance, de la première étude concernant l'élimination des métaux et du cyanure d'eaux usées par des zones humides artificielles en écoulement de sub-surface. / This thesis presents various aspects of polishing the electroplating wastewater in constructed wetlands: analysis of the performance, study on the operation and configuration effects, effects of various carbon sources, analysis of the substrate (bed media), analysis of plants, and design issues.The goals of the experiment were to: (i) study the feasibility of polishing electroplating effluent, (ii) study the effect of operating schemes, plants, bed media and wastewater strength, (iii) to elucidate metal removal mechanisms in the CW microcosms.This study furnished new information and expanded the existing knowledge on industrial wastewater treatment in constructed wetlands. In fact, this is, to the best knowledge, the first publication studying the removal of metals and cyanide from electroplating wastewater in subsurface flow constructed wetlands. The aim of this study was to study the polishing of the electroplating wastewater pretreated using physical-chemical methods.
