METHOD FOR TREATING SEWAGE SLUDGE AND WASTEWATER TREATMENT PLANT |
摘要 |
The invention describes a method for treating sewage sludge through the treatment steps of hydrolysing (2) the sewage sludge (1) and digesting (11) the hydrolysed sewage sludge (10), which has undergone hydrolysis (2), for the anaerobic treatment of the sewage sludge (1), and through the step of separating phosphate from the at least partially treated sewage sludge (3). Phosphate is separated after the treatment step of hydrolysing (2) and before the treatment step of digesting (11) the hydrolysed sewage sludge (3), wherein the sewage sludge (10), without the phosphate portion separated in the phosphate separation step, is fed to the anaerobic treatment performed through digestion (11). |
