O crescimento desordenado da popula??o faz com que se tornem necess?rios novos estudos a respeito de diferentes fontes de combust?veis renov?veis. Uma dessas fontes ? o bioss?lido de esgoto, representado pelo ac?mulo de s?lidos suspensos e pela prolifera??o de micro-organismos. No presente trabalho foi realizada a caracteriza??o f?sico-qu?mica do bioss?lido, avaliando seu teor de umidade, cinzas e material vol?til. Essas an?lises foram feitas de acordo com m?todos ASTM. Tamb?m foi feita a an?lise elementar do bioss?lido e a extra??o do bio-?leo. A caracteriza??o do bio-?leo foi realizada atrav?s da espectroscopia de infravermelho. Assim os dados obtidos foram usados na classifica??o por An?lise das Componentes Principais e An?lise Hier?rquica por Agrupamento, onde foi poss?vel diferenciar as amostras de cada local coletado. / Disserta??o (Mestrado) ?

One such source is the sewage sludge, suspended solids represented by accumulation and the proliferation of microorganisms. In the present work was carried out physico-chemical characterization of sludge, evaluating its moisture, ash, volatile material. These analyzes were made according to ASTM methods. Also elemental analysis was made of sludge and extraction of bio-oil. The characterization of the bio-oil was accomplished by infrared spectroscopy. Thus the data obtained were used in the rating analysis of Principal Component Analysis and Hierarchical Clustering, where it was possible to differentiate the samples collected at each location.

However, studies on the growth response of native forest tree species to biosolids fertilization are still very incipient. The objective of this study was to evaluate the effects of sewage sludge biosolids on the growth of seven Atlantic Forest tree species, commonly used in restoration plantations. In a field experiment in Serop?dica, RJ, was evaluated the effect of four doses of biosolids (0, 2, 4 and 8 L per planting pit) and a treatment with mineral fertilization on the growth of seven tree species. During 19 months, growth (height and diameter at soil height - DNS) and survival of the species Schinus terebinthifolius Radd were monitored. (Aroeira), Lafoensia glyptocarpa KOEHNE (mirindiba), Inga laurina (Sw.) Willd. (Ingla-laurine), Senna multijuga (Rich.) (Pau-cigarra), Genipa americana (Vell.) Brenan (genipapo). In a second planting, under the same treatments, the species Peltophorum dubium (Spreng.) Taub (dry flour) and Enterolobium contortisiliquum (Vell.) Morong (black ear) were monitored for 9 months. At the end of the monitoring period, the crown diameter and macronutrient leaf contents were also evaluated. The dose of up to 4 L of biosolid did not compromise the survival of the plants in the field. However, under the mineral fertilizer treatment, all plants of S. multijuga, 80% of I. laurina and 67% of plants of L. glyptocarpa, probably due to the effect of fertilizer salts on soil water potential Conjugated to the occurrence of a drought period after planting. The increase of the biosolid dose corresponded to a linear increase of the growth of the DNS of S. terebinthifolius, and of the growth in height, DNS and cup diameter of P. dubium. However, application of the 8 L dose of biosolids reduced up to 50% growth of S. multijuga. The species I. laurina, G. americana and E. contortisiliquum showed no response to biosolid application. Mineral fertilization significantly reduced the growth of S. terebinthifolius (p <0.05) and a similar trend was observed for G. americana, L. glyptocarpa and P. dubium (p <0.17). However, this same treatment increased the height growth of E. contortisiliquum by 70% in relation to the non-fertilized control. In general, the treatments did not significantly alter the macronutrient contents of the evaluated species. A clear exception was the increase of the Ca content in plants of L. glyptocarpa that received biosolids, and the increase of the N content in P. dubium treated with mineral fertilization. It is concluded that the different native forest species present different responses to the biosolid application. The dose of 4 L of biosolid was the only one that had no negative effect or promoted the growth of the Atlantic Forest tree species evaluated. It is recommended that similar studies be carried out on other soil types with other species in order to refine the recommendation of the use of biosolids in forest restoration plantations. Finally, caution is suggested in the use of mineral fertilizers for plantations with native species, as this practice may result in mortality or slow the growth of some species. / O lodo de esgoto tratado, denominado bioss?lido, cont?m altos teores de macronutrientes e mat?ria org?nica sendo, potencialmente, um ?timo insumo para utiliza??o agr?cola e florestal. Entretanto, estudos sobre a resposta de crescimento de esp?cies arb?reas florestais nativas ? aduba??o com bioss?lido ainda s?o muito incipientes. O objetivo desse estudo foi avaliar os efeitos proporcionados pela aplica??o de bioss?lido de lodo de esgoto sobre o crescimento de sete esp?cies arb?reas da Mata Atl?ntica, comumente utilizadas em plantios de restaura??o. Em um experimento de campo em Serop?dica, RJ, foi avaliado o efeito de quatro doses de bioss?lido (0, 2, 4 e 8 L por cova de plantio) e um tratamento com fertiliza??o mineral sobre o crescimento de sete esp?cies arb?reas. Ao longo de 19 meses foi monitorado o crescimento (altura e di?metro ? altura do solo ? DNS) e a sobreviv?ncia das esp?cies Schinus terebinthifolius Radd. (aroeira), Lafoensia glyptocarpa KOEHNE (mirindiba), Inga laurina (Sw.) Willd. (ing?-laurina), Senna multijuga (Rich.) (pau-cigarra), Genipa americana (Vell.) Brenan (jenipapo). Em um segundo plantio, sob os mesmos tratamentos, foi monitorado por 9 meses as esp?cies Peltophorum dubium (Spreng.) Taub (farinha-seca) e Enterolobium contortisiliquum (Vell.) Morong (orelha-de-negro). Ao final do per?odo de monitoramento, foi avaliado tamb?m o di?metro de copa e os teores foliares de macronutrientes. A dose de at? 4 L de bioss?lido n?o comprometeu a sobreviv?ncia das plantas em campo. Por?m, sob o tratamento com fertilizante mineral houve mortalidade de todas as plantas de S. multijuga, 80% de I. laurina e 67% das plantas de L. glyptocarpa, provavelmente em raz?o do efeito dos sais do fertilizante sobre o potencial h?drico do solo conjugado ? ocorr?ncia de um per?odo de estiagem ap?s o plantio. O aumento da dose de bioss?lido correspondeu a um aumento linear do crescimento do DNS de S. terebinthifolius, e do crescimento em altura, DNS e di?metro de copa de P. dubium. Entretanto, a aplica??o da dose de 8 L de bioss?lido reduziu em at? 50% o crescimento de S. multijuga. As esp?cies I. laurina, G. americana e E. contortisiliquum n?o apresentaram resposta ? aplica??o de bioss?lido. A aduba??o mineral reduziu significativamente o crescimento de S. terebinthifolius (p<0,05) e tend?ncia similar foi observada para G. americana, L. glyptocarpa e P. dubium (p<0,17). Entretanto, esse mesmo tratamento aumentou em 70% o crescimento em altura de E. contortisiliquum em rela??o ao controle n?o adubado. Em geral, os tratamentos n?o alteraram significativamente os teores de macronutrientes foliares das esp?cies avaliadas. Uma clara exce??o foi o aumento do teor de Ca em plantas de L. glyptocarpa que receberam bioss?lido, e o aumento do teor de N em P. dubium tratado com aduba??o mineral. Conclui-se que as diferentes esp?cies florestais nativas apresentam respostas distintas ? aplica??o de bioss?lido. A dose de 4 L/cova de bioss?lido foi a ?nica que n?o teve efeito negativo ou promoveu o crescimento da das esp?cies arb?reas da Mata Atl?ntica avaliadas. Recomenda-se que estudos similares sejam efetuados em outros tipos de solo com outras esp?cies de modo refinar a recomenda??o do uso do bioss?lido em plantios de restaura??o florestal. Por fim, sugere-se cautela no uso de fertilizantes minerais para plantios com esp?cies nativas, pois esta pr?tica pode resultar em mortalidade ou retardar o crescimento de algumas esp?cies.
