Biological reactor for treatment of domestic sewage

摘要

The biological sewage treatment reactor is characterised by the shape of a housing (2) with a rectangular shape that protects against the pressure of the native soil (3),and in the upper part there are sewage pipes (4),where there are four purification zones within the housing (2): the first zone consists of the appropriate (6) and the third (12) oxygen-free zone of the melted PET bottles (7, 13),and the second aerial zone (10) and fourth settlement zone (19) of plastic packages (11, 20),constructing a support structure appropriate to the areas above, the area of which is covered by periods of between 80 and 98%,where the appropriate (6) and (10) effluents are continuously flowing through the zone,and the oxygen-free zone (12) and the sediment zone (19) are constantly submerged in sewage. In addition, a perforated line level (15) is installed in the oxygen-free zone (12),having holes of a diameter preventing the passage of ground PET bottles (13) together with purified effluents removed from the housing (2),closed by reservoir (16) to any settlement and connected to a vertical drainage pipe (17),for filling any sediment from the reservoir (16),and with drainage (18),located at the same height as the upper edge of the oxygen-free zone (12).
