Method for increasing biogas production in the centres of anaerobic treatment of sewage sludge in the municipal sewage treatment plants, with the application of organic carbon extraction from the municipal waste undersize fraction

摘要

way of increasing biogas production in lymph anaerobowej treatment of sewage sludge in municipal sewage treatment by applying extraction organic carbon fractions of podsitowej municipal waste.the way is that the fraction podsitowa organic waste (4), is placed inside cieczo - permeable partition (10), a pore size to a fraction podsitowej municipal waste not wydostawau0142o beyond this partition, secreted extraction zone fp ok 2, and at the same time, large enoughto the restricted zone partition (10) can be anaerobowej fermentation liquid phase zone (1), which after passing through the extraction zone (2) transfers the extracted organic carbon to a zone of increased organic carbon content (3), where the liquid kierowan and it's back to the anaerobowej fermentation (1),a fermentation zone (1) continuously added fresh sewage sludge (7) and from this area also discharged continuously sludge fermented (8).
