More Information
Summary:The invention relates to a process for aerobic composting of sludges resulting from anaerobic treatment of wastes in purification plants. According to the invention, the process consists in mixing the sludges resulting from anaerobic treatment of wastes in purification plants with saw dust in a volume ratio of 1:2.5 and with straws in a volume ratio of 1:5.9, aeration being provided through a forced aeration system for finally obtaining a compost that can be used as an agricultural fertilizer or as a plant substrate. Invenţia se referă la un procedeu de compostare aerobă a nămolurilor rezultate din tratarea anaerobă a deşeurilor din staţiile de epurare. Procedeul conform invenţiei constă în amestecarea nămolurilor, rezultate din tratarea anaerobă a deşeurilor din staţiile de epurare, cu rumeguş în raport volumetric de 1 : 2,5, iar cu paie în raport volumetric de 1 : 5,9, aerarea fiind asigurată printr-un sistem de aerare forţată pentru obţinerea unui compost care poate fi utilizat ca fertilizant în agricultură sau ca substrat pentru plante.
