“…A utilização de processos irradiados por radiação solar deve, sempre que possível ser incentivada, já que apresentam eficiência de degradação compatíveis aos processos assistidos por radiação artificial, e o uso da radiação ultravioleta artificial acaba por tornar o processo dispendioso em virtude do consumo de energia e da necessidade de materiais como o quartzo que apresenta preços elevados. 6,16,17 Diante do exposto, o presente trabalho teve como objetivo avaliar a eficiência do processo Foto-Fenton e Foto-Fenton Solar aplicado na degradação do corante têxtil Preto Biozol.…”

The present work aimed to evaluate the efficiency of the photo-Fenton process assisted by artificial or solar light applied in the treatment of synthetic textile effluent. For the study of solar radiation was designed and built a solar reactor type Compound Parabolic Collector (CPC), and the efficiency of the treatment was analyzed in terms of color removal, chemical oxygen demand (COD) and spectral scanning of samples. The results obtained showed that the photo-Fenton process was efficient in discoloring the effluent, with emphasis to the study conducted by sunlight that in all operational conditions of work presented removal rates above 90%. In terms of COD, the best efficiency was obtained when 1250 mg L -1 e :62,5 mg L -1 showing rates of 85.40% and 50.20% for the process with artificial or solar light respectively.

This work aimed to predict the physical–chemical characteristics of leachate according to the analysis of the solubilized extract from urban household solid waste (UHSW), on a laboratory scale, in the city of Belém/PA, Brazil. The neighborhoods where the waste was collected were sectorized based on geographic and socioeconomic data, with family income as the main parameter. After collection, the material was sent to the segregation area, where a gravimetric analysis of the UHSW was performed and fractions (paper, cardboard, Tetra Pak, rigid plastic, malleable plastic, metals, glass, organic matter, sanitary waste, fabrics and rejects) were segregated. After the gravimetric characterization, it was found that the highest average proportions were 55.57% organic matter, 14.26% sanitary waste and 9.97% malleable plastic. The organic fraction was selected and subjected to drying, crushing, sieving and packaging pretreatment, and then the solubilized extract of this fraction was obtained according to NBR No. 10.006/2004 of the Brazilian Association of Technical Standards. In the analyses of the solubilized extract, values for total nitrogen (201.80 to 359.90 mg·L−1), ammonia nitrogen (161 to 289 mg·L−1), nitrate (10 to 40 mg·L−1) and chemical oxygen demand were obtained (28,701 mg·L−1 to 38,608 mg·L−1), indicating the similarity of the waste solubilization conditions to those of leachate from landfills, in addition to being in noncompliance with environmental and health legislation, thus making it necessary to have an efficient waste management system, which avoids the release of waste into the environment that would result in environmental impacts similar to those of leachate contact with the environment.
