Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, their distribution, and the threats affecting them. We compiled a global dataset of sampled earthworm communities from 6928 sites in 57 countries as a basis for predicting patterns in earthworm diversity, abundance, and biomass. We found that local species richness and abundance typically peaked at higher latitudes, displaying patterns opposite to those observed in aboveground organisms. However, high species dissimilarity across tropical locations may cause diversity across the entirety of the tropics to be higher than elsewhere. Climate variables were found to be more important in shaping earthworm communities than soil properties or habitat cover. These findings suggest that climate change may have serious implications for earthworm communities and for the functions they provide. |

Abstract: Chemical phosphorus removal with hydrated lime was evaluated on effluents from different biological treatment processes applied to swine manure. The objective of this study was to establish the most suitable process for this kind of wastewater treatment. Effluents a UASB reactor, a nitrification reactor (NR), a modified Lutzak?Ettinger (MLE) reactor and a deammonification (DMX) reactor were evaluated. A comprehensive study was developed at laboratory scale to evaluate the effect of possible interferences, including alkalinity, total organic carbon, and ammonia, on phosphorus precipitation. The highest soluble phosphorus (Psol) removal efficiency and the lowest Ca:P molar ratio were obtained for the NR effluent (92% and 2.0, respectively). The good performance of the NR effluent could be attributed to the low level of ammoniacal nitrogen and alkalinity and to the presence of a relatively high concentration of calcium. Highly promising results were also obtained in field experiments, where a phosphorus removal unit was installed as the last step in a swine manure treatment system, and precipitation was applied to effluent from the NR. In this case, efficiencies of Psol removal higher than 90% were obtained. The produced sludge was rich in phosphorus and could be used as, for example, fertilizer. The results obtained in this work showed the importance of applying an efficient treatment system to swine manure for reduction of ammoniacal nitrogen, alkalinity, and carbon before chemical removal of phosphorus by precipitation with hydrated lime. Resumo: A remoção química do fósforo com cal hidratada foi avaliada em efluentes de diferentes processos de tratamento biológico aplicados ao esterco de suínos. O objetivo deste estudo foi estabelecer o processo mais adequado para esse tipo de tratamento de efluentes. Efluentes foram avaliados um reator UASB, um reator de nitrificação (NR), um reator modificado Lutzak-Ettinger (MLE) e um reator de desaminificação (DMX). Um estudo abrangente foi desenvolvido em escala de laboratório para avaliar o efeito de possíveis interferências, incluindo alcalinidade, carbono orgânico total e amônia, na precipitação de fósforo. A maior eficiência de remoção de fósforo solúvel (Psol) e a menor razão molar Ca: P foram obtidas para o efluente NR (92% e 2,0, respectivamente). O bom desempenho do efluente NR pode ser atribuído ao baixo nível de nitrogênio e alcalinidade amoniacal e à presença de uma concentração relativamente alta de cálcio. Resultados altamente promissores também foram obtidos em experimentos de campo, onde uma unidade de remoção de fósforo foi instalada como último passo em um sistema de tratamento de suínos e a precipitação foi aplicada ao efluente do NR. Neste caso, foram obtidas eficiências de remoção de Psol superiores a 90%. O lodo produzido era rico em fósforo e podia ser usado como fertilizante, por exemplo. Os resultados obtidos neste trabalho mostraram a importância da aplicação de um sistema de tratamento eficiente ao esterco suíno para redução do nitrogênio amoniacal, alcalinidade e carbono, antes da remoção química do fósforo por precipitação com cal hidratada.

Efluentes foram avaliados um reator UASB, um reator de nitrificação (NR), um reator modificado Lutzak-Ettinger (MLE) e um reator de desaminificação (DMX). Um estudo abrangente foi desenvolvido em escala de laboratório para avaliar o efeito de possíveis interferências, incluindo alcalinidade, carbono orgânico total e amônia, na precipitação de fósforo. A maior eficiência de remoção de fósforo solúvel (Psol) e a menor razão molar Ca: P foram obtidas para o efluente NR (92% e 2,0, respectivamente). O bom desempenho do efluente NR pode ser atribuído ao baixo nível de nitrogênio e alcalinidade amoniacal e à presença de uma concentração relativamente alta de cálcio. Resultados altamente promissores também foram obtidos em experimentos de campo, onde uma unidade de remoção de fósforo foi instalada como último passo em um sistema de tratamento de suínos e a precipitação foi aplicada ao efluente do NR. Neste caso, foram obtidas eficiências de remoção de Psol superiores a 90%. O lodo produzido era rico em fósforo e podia ser usado como fertilizante, por exemplo. Os resultados obtidos neste trabalho mostraram a importância da aplicação de um sistema de tratamento eficiente ao esterco suíno para redução do nitrogênio amoniacal, alcalinidade e carbono, antes da remoção química do fósforo por precipitação com cal hidratada. 650 $aEffluents 650 $aPig manure 650 $aDejeto 650 $aFósforo 650 $aSuíno 650 $aTratamento 700 1 $aANTES, F.
