Abstract
A process for the biological purification of sewage is specified, with which sewage (AW), containing dissolved pollutants, and air (LT) are fed together to a reactor (1) via at least two mutually separate nozzles (3,4). To achieve a high substance exchange in the reactor (1), the streams of the two-substance mixture emanating from the nozzles (3,4) are conducted such that they make impact with each other in the said reactor in an impact zone (PZ). The sewage (AW) is passed from the reactor (1) into Pa settling tank (8), in which bio sludge settles.
Claims8
An apparatus for biological purification of pollutant-containing sewage with introduction of air into the sewage for enhancing the purification process, said apparatus comprising:
- a reactor for receiving a two-substance mixture of sewage with air, said reactor having a high turbulence zone;
- at least two spaced conduit tubes for delivering the two-substance mixture of sewage with air into said reactor, said at least two conduit tubes having inlets and outlets thereof arranged at substantially same levels, with said outlets being located in said high turbulence zone and arranged in a facing relationship to each other, whereby streams of the two-substance mixture of sewage and air discharge from said outlets impacts on each other creating high turbulence;
- at least two nozzles projecting into said inlets of said at least two conduit tubes for injecting the two-substance mixture of sewage and air into said at least two conduits tubes;
- and
- a settling tank connected with said reactor.
