treatment for anaerobic digestion of waste water from olive oil mill and oil by pressing of olives after extraction from the same polifenolica fraction of whey with production of biogas and organic fertilizers supplement

摘要

A process for the integral recovery of components and chemical compounds from olive mill wastewaters and olive husks with membrane technologies, resins an treatments of the dephenolised material product with anaerobic and aerobic attached-biomass columns and with aerobic tray separation column, as a preliminary phase for exploiting said wastes for the production of biogas and fertilizers having high-quality and high availability in the soil. The disclosed treatment is characterized by the following steps: pre-dilution, centrifugation; selective fractionation for the recovery of polyphenol compounds through a membrane process and adsorption on resins; pretreatment in aerobic and anaerobic attached-biomass columns and tray separation column; anaerobic biodigestion for biogas and fertilisers production; cogeneration for the production of a thermal and electrical power vector; production of water reusable in the process, having hydro-chemical characteristics suitable to civil use.
