Tratamento de efluentes de refinaria de petróleo em reatores com Aspergillus niger

Abstract: Neste trabalho, avaliou-se o efeito do tempo de detenção hidráulica (TDH) no desempenho de três reatores aeróbios inoculados com Aspergillus niger AN400, usados para tratamento de efluentes de refinarias de petróleo. Cada reator foi operado com um tempo de detenção hidráulica diferente: 4, 8 e 12 horas, durante 152 dias. Eles possuíam leito fixo de espuma de poliuretano e o escoamento era ascendente e contínuo. Determinaram-se: pH, fenóis, demanda química de oxigênio (DQO), amônia, nitrito e nitrato, no afluen… Show more

“…Aspergillus niger is a haploid filamentous fungus, found in soil, plants and air, considered one of the most important microorganisms used in biotechnology. Niger species have proven efficiency in the degradation of recalcitrant effluent compounds from various industries such as pharmaceuticals, olive oil, breweries, among others (Santaella et al, 2009;Deepika et al, 2014). Also its characteristic is the use of dyes as substrate turning them into non-toxic compounds, or of low toxicity.…”

“…Phanerochaete chrysosporium e Aspergillus niger, possuem capacidade de remover poluentes orgânicos recalcitrantes, por exemplo, o fenol (FOUNTOULAKIS et al, 2002;HAI et al, 2006;SANTAELLA et al, 2009;PASSOS et al, 2009) e os metais (YUN-GUO et al, 2006), por meio de atividades metabólicas, pela produção de enzimas e propriedades de adsorção. Aspergillus niger, Aspergillus terreus, Trichoderma causa efeitos tóxicos à biota do tratamento, uma vez que dentro das células os íons metálicos podem se ligar a proteínas, deslocando alguns íons de suas posições habituais e prejudicando as suas funções metabó-licas (CHIPASA, 2003;GADD, 1992 As placas foram incubadas em uma sala com temperaturas variando de 25 a 32°C, com 12 horas de escuro e 12 horas de iluminação.…”

“…The freshwater requirements of such plants vary from 0.4 to 1.6 times the total volume of oil processed in the plant (Santaella et al, 2009). For transforming crude oil into gasoline, diesel, aviation kerosene, or naphtha, a long list of different chemicals and solvents are used (Alva-Argá ez et al, 2007).…”

“…For transforming crude oil into gasoline, diesel, aviation kerosene, or naphtha, a long list of different chemicals and solvents are used (Alva-Argá ez et al, 2007). Thus, the effluents of these plants are usually heavily contaminated with several types of organic and inorganic pollutants such as phenols, sulphides, ammonium, cyanides, polyaromatic and aliphatic hydrocarbons, and different inorganic salts (Santaella et al, 2009). Most oil refineries have treatment plants, but even after treatment the final effluent contains many contaminants.…”
