Abstract
"PROCESSO MISTO PARA DESINFECçãO E APROVEITAMENTO NA AGRICULTURA DE LODO DE ESGOTO E RESìDUOS VEGETAIS". A presente invenção refere-se a um processo para aproveitamento do lodo de esgoto na agricultura. A matéria-prima é o lodo de esgoto doméstico proveniente de estação de tratamento primário que não passou por qualquer tratamento prévio visando estabilização química ou desinfecção do material, além de resíduos vegetais provenientes de jardins e ruas. Não são incorporados aos materiais originais outros produtos químicos oxidantes, tóxicos ou que visem alterar o pH, bem como fonte externa de calor, fatos estes que caracterizam o processo como ambientalmente sustentável, o que o torna útil a empresas de saneamento urbano. O processo baseia-se, portanto, na estabilização físico-química e microbiológica do lodo em presença de podas de plantas processadas, através do uso seqüencial de processos aeróbio e anaeróbio com o objetivo de síntese de fertilizante agrícola isento de patógenos humanos."MIXED PROCESS FOR DISINFECTION AND USE IN SEWAGE SLUDGE AGRICULTURE AND VEGETABLE WASTE". The present invention relates to a process for using sewage sludge in agriculture. The raw material is domestic sewage sludge from a primary treatment plant that has not undergone any prior treatment for chemical stabilization or disinfection of the material, as well as vegetable waste from gardens and streets. Other oxidizing, toxic or pH-altering chemicals as well as external heat sources are not incorporated into the original materials, which characterize the process as environmentally sustainable, which makes it useful for urban sanitation companies. Therefore, the process is based on the physicochemical and microbiological stabilization of sludge in the presence of pruning of processed plants, through the sequential use of aerobic and anaerobic processes with the objective of synthesizing human pathogen-free agricultural fertilizer.
