Microbiological treatment process and device for organic waste

摘要

Microbiological treatment process is claimed for organic waste, esp. native organic waste. The organic components of the waste are partially transferred into water soluble forms by microbiological reduction under forced aeration in a first reaction chamber, in the form of one or more interchangeable composting drums. Simultaneously or sequentially, these components are treated at fixed intervals to remove the soluble components by continuous spraying with extraction water, such as tempered water and / or salt, acid or alkaline solutions. The organic fraction is then removed from the aqueous extract and fed to a second reaction chamber for further microbiological treatment, where they are aerobically or non aerobically treated. The aqueous soln. which arises from this is alkalised by the microbiological reduction reaction and is either fed back to the next extractive nutrient removal in the first reaction chamber or removed separately. Also claimed is a device to carry out the above process with the first chamber (1) formed as a closed fermenter, having feed and discharge flaps (6,7) for the organic waste (8).
