Abstract

Przedmiotem wynalazku jest sposób oczyszczania ścieków metodą mechaniczno-biologiczną, mającą zastosowanie w oczyszczaniu ścieków zawierających trudno biodegradowalne związki o charakterze ksenobiotyków. Sposób oczyszczania ścieków charakteryzuje się tym, że po oczyszczaniu mechanicznym i korzystnie oczyszczaniu chemicznym a przed oczyszczaniem biologicznym ścieki oczyszcza się dwustopniowo. Osad nadmierny po przejściu z reaktora biologicznego oraz kolejno przez co najmniej jeden osadnik wtórny zagęszcza się w urządzeniu do zagęszczania do zawartości suchej masy od 40 do 300 g/dm3 i recyrkuluje się go do dozownika osadu, skąd rozdzielając go na dwa strumienie podaje się go do dwóch reaktorów.The subject of the invention is a method of wastewater treatment by a mechanical-biological method, applicable in wastewater treatment containing hard-biodegradable xenobiotics. The method of wastewater treatment is characterized by the fact that after mechanical and preferably chemical treatment and before biological treatment, the wastewater is treated in two stages. Excessive sludge after passing from the biological reactor and subsequently through at least one secondary settler is concentrated in a compaction device to a dry matter content of 40 to 300 g / dm3 and it is recirculated to the sludge dispenser, from where it is divided into two streams, it is fed to two reactors.
