Abstract:
The invention relates to a method for wastewater treatment utilizing an anaerobic treatment of primary sludge (PS) in a septic tank (5), and a separate treatment of excess sludge (ÜS). The excess sludge (ÜS) is separated from the primary sludge (PS) before the anaerobic treatment, solubilized in a hydrolysis treatment and liquefied, and subjected to a separate anaerobic treatment independently of the primary sludge (PS).
