Document Type and Number:
WIPO Patent Application WO/2011/006961
Kind Code:
A3
Abstract:
The invention relates to a black water renovation and storage device for an onboard toilet on board a vehicle, comprising a waste water tank (10) having an inflow opening for feeding black water into the waste water tank and an outflow opening for removing black water from the waste water tank, a comminution device (30, macerator pump) for comminuting coarse components in the black water, a reactor vessel (60) designed to subject black water to an electrolytic oxidative waste water purification process therein, and an anti-foaming tank (40) designed to reduce the foam developing during the purification of the waste water. According to the invention, the outflow opening of the waste water tank (10) is connected to the comminution device (30) by way of a waste water line, the waste water line opens into a comminution circuit in which the comminution device (30) and the anti-foaming tank (40) are disposed, a first valve assembly (22) is provided, which has a first position, in which the black water is circulated in the comminution circuit, and a second position, in which the water is circulated in an oxidation circuit, and the anti-foaming tank (40) and the reactor vessel (60) are disposed in the oxidation circuit. The anti-foaming tank (40) has an upper tangential inlet opening (45) and a lower inlet opening (44) through which the water is alternately returned into the anti-foaming tank (40).
