<p>PROBLEM TO BE SOLVED: To provide an apparatus for treating excrement wastewater which enables measures for purification tank sludge sufficiently and can attempt the stabilization of biotreatment. SOLUTION: A treatment apparatus for excrement wastewater has pretreatment means 1, 2 which introduces excrement wastewater containing at least raw excrement and purification tank sludge and removes contaminants, a prereaction means 3 for oxidation-treating the excrement wastewater treated by the pretreatment means 1, 2, a reaction means 4 for nitrification- denitrification-treating the excrement wastewater treated by the prereaction means 3, and a solid-liquid separation means 5 for solid-liquid separating the suspension sent from the reaction means 4.</p> |
