A motor train unit feces collecting system and an operating method thereof solve the problems of high energy consumption and complicated structure. A reciprocating motion device directly drives a piston to alternately change the positive and negative pressure in sewage disposal, without providing an intermediate tank, so the system is simple in structure and low in energy consumption. The system includes a blow-off line for connecting a toilet with a sewage tank and connected to a positive and negative pressure switching device which includes a by-pass line, the openings at both ends of the by-pass line are in communication with the blow-off line, a piston is disposed in the by-pass line and connected to a reciprocating motion device which drives the piston to move to change the positive and negative pressure condition of upper and lower regions of the by-pass line.

The invention relates to a method for treating organically contaminated wastewater and/or organically contaminated wet waste, in particular for treating sanitary wastewater (15) in trains. According to the invention, the method comprises the following steps: a) purifying the organically contaminated wastewater and/or the organically contaminated wet waste, in particular the sanitary wastewater (15) in trains, in a bioreactor (20), b) feeding the wastewater (24) at least partially purified in the bioreactor (20) into a conditioning plant (30), c) at least partial phase separation of the partially purified wastewater (24) in the conditioning plant (30), d) obtaining a liquid portion and a solid portion of the at least partially purified wastewater (24).

A stand-alone toilet system is powered by photovoltaic cells to operate a dehumidifier from which water is extracted from the atmosphere by dehumidification and used for flushing; an electronic compressor is situated in the toilet tank to compress air which is used with water in the flush cycle; a motorized or hydraulic hinge is utilized to open and close a toilet cover automatically which can be locked in place by electromagnet means to create an airtight seal in the closed position; a heating element and a UV lamp are situated inside the “treatment facility” of the toilet system to evaporate liquid and sanitize waste content therein respectively.

Waste transfer system for a toilet of a public transport vehicle that discharges into an on-board waste aerated storage tank, comprising a waste intermediate tank (1), means for generating negative or positive pressure inside said waste intermediate tank (1), and a discharge valve means (3,5,6,7) to regulate the flow through a first waste passage (8) between a toilet bowl (2) and said waste intermediate tank (1) and through a second waste passage (11) between said waste intermediate tank (1) and said waste storage tank, characterized in that said discharge valve means comprise a multi-port discharge valve (3) connectable to an inlet/outlet port (4) of the waste intermediate tank (1), said multi-port discharge valve (3) being configured to provide, in a first working position, direct communication between said toilet bowl (2) and said waste intermediate tank (1) when negative pressure is supplied inside said waste intermediate tank (1) and to provide, in a second working position, direct communication between the waste intermediate tank (1) and the waste storage tank when positive pressure is supplied in the said waste intermediate tank (1).

An additive sub-system for a wastewater management system of a vehicle including at least one holding tank and a toilet has a controller, at least one additive dispenser and a pump. The at least one additive dispenser is in fluid communication with the at least one holding tank or the toilet. The pump is associated with each additive dispenser of the at least one additive dispensers. Each pump is controlled by the controller to dispense an additive from the at least one additive dispenser to the at least one holding tank or the toilet.

A toilet sub-system of a wastewater management vehicle includes a toilet and a housing. The housing is associated with the toilet and includes a macerator pumping arrangement having a macerator and a pump. The macerator includes a plurality of macerating knives. The pump is an air pump providing positive pressure in a macerator chamber to pump waste from the macerator chamber. The sub-system further includes at least one motor for driving the pumps and the macerator. The macerator pumping arrangement is operative in a macerating mode and a pumping mode, such that in the macerating mode the first motor first drives the macerating knives to macerate the waste and subsequently in the pumping mode the waste is pumped out of the macerating chamber by positive pressure.

An apparatus for delivering wastewater from a recreational vehicle to a drain includes a housing having an outer wall and an inner wall generally perpendicular or slightly angled to the outer wall. The housing and the inner wall define an inlet chamber above the inner wall and a further chamber below the inner wall. The housing further includes an outlet downwardly extending from the inlet chamber.

A drainage system for an aircraft is taught herein. The drainage system includes a drain tube defining an orifice. The drainage system further includes a cover movable between a first cover position and a second cover position. The cover is configured to overlay the orifice when the cover is in the first cover position. The cover is configured to expose the orifice when the cover is in the second cover position. The cover is configured to move between the first cover position and the second cover position in the presence of air pressure.
