O presente trabalho teve como objetivo principal acompanhar o tratamento do lodo de esgoto gerado na estacao de tratamento de esgotos de Jundiai atraves da compostagem termofilica em leiras revolvidas mecanicamente sob a perspectiva da higienizacao e producao de biossolido para uso agricola, em conformidade com o arcabouco legal existente. Foram monitorados nove lotes de esgoto, entre janeiro e dezembro de 2014. O tempo de acompanhamento de cada lote variou de 64 a 124 dias, com realizacao de coletas somente apos o fim do tratamento, com excecao da temperatura que foi monitorada durante toda a fase termofilica do processo. Os seguintes parâmetros fisico quimicos foram considerados: temperatura, pH, umidade, solidos totais e orgânicos, carbono orgânico, nitrogenio, relacao C/N, capacidade de troca cationica CTC, metais pesados e nutrientes. Por sua vez, as variaveis microbiologicas acompanhadas foram: coliformes termotolerantes, Salmonella sp. e ovos de helmintos. Os resultados das analises laboratoriais evidenciaram nitido decaimento microbiano apos a compostagem termofilica. Ausencia de salmonela ja no lodo bruto, remocao total de coliformes termotolerantes e valores abaixo do limite estabelecido pela Resolucao CONAMA 375/2006 e instrucoes normativas do Ministerio da Agricultura, com reducao media de 80,2 por cento , no que se refere a presenca de ovos viaveis de helmintos...(AU) The present study aimed to monitor the treatment of the generated sewage sludge treatment plant in Jundiai sewage through thermophilic composting in windrows mechanically plowed from the perspective of disinfection and production of biosolid for agricultural use, in accordance with the legal framework existing. Nine lots of sewage were monitored between January and December 2014. The monitoring period of time of each lot varied from 64 to 124, with sampling only after the end of treatment, except the temperature was monitored throughout the phase thermophilic process. The following physical-chemical parameters were considered: temperature, pH, moisture, total and organic solids, organic carbon, nitrogen, C/N, cation exchange capacity - CTC, heavy metals and nutrients. In turn, the microbiological variables were monitored: thermotolerants coliforms, Salmonella sp. and helminth eggs. The results of laboratory analyzes showed sharp microbial decay after the thermophilic composting. Salmonella absence already raw sludge, total removal of fecal coliforms and values below the limit established by CONAMA Resolution 375/2006 and regulatory instructions of the Ministry of Agriculture, with an average reduction of 80.2 per cent in relation to the presence of viable helminth eggs...(AU)
