Sewage treatment apparatus
First Claim
1. A sewage treatment apparatus comprising a hollow, elongated casing having an inlet for reception of sewage, a discharge opening and a discharge outlet, a macerating chamber in said casing, an intercepting chamber in said casing located below said macerating chamber for intercepting the passage of said sewage through said discharge outlet and causing said sewage to pass through said discharge opening, a valve means located between said macerating chamber and said intercepting chamber, means for closing said valve means to temporarily hold a batch of sewage in said macerating chamber, means for macerating the sewage as it is held in said macerating chamber, means for opening said valve means to deposit the sewage from said macerating chamber into said intercepting chamber, a second valve means at the outlet of said casing and below said intercepting chamber, means for opening said second valve means to discharge the sewage from the discharge outlet of said casing, a holding tank connected to said discharge opening and means for optionally transferring said sewage through said discharge opening to said holding tank or through said discharge outlet.

Abstract
A sewage treatment apparatus for use in a toilet room comprises a casing with an inlet for reception of sewage and a discharge outlet. There are means within a chamber in the casing for the chemical treatment and agitation of the sewage to reduce the sewage to a substantially sterile slurry. There is a series of valves within the casing to control the passage of the sewage after it has been treated to be directly discharged through the casing outlet, or optionally discharged to a connected, remotely located holding tank.

- 1. A sewage treatment apparatus comprising a hollow, elongated casing having an inlet for reception of sewage, a discharge opening and a discharge outlet, a macerating chamber in said casing, an intercepting chamber in said casing located below said macerating chamber for intercepting the passage of said sewage through said discharge outlet and causing said sewage to pass through said discharge opening, a valve means located between said macerating chamber and said intercepting chamber, means for closing said valve means to temporarily hold a batch of sewage in said macerating chamber, means for macerating the sewage as it is held in said macerating chamber, means for opening said valve means to deposit the sewage from said macerating chamber into said intercepting chamber, a second valve means at the outlet of said casing and below said intercepting chamber, means for opening said second valve means to discharge the sewage from the discharge outlet of said casing, a holding tank connected to said discharge opening and means for optionally transferring said sewage through said discharge opening to said holding tank or through said discharge outlet.
- 4. In a waste disposal apparatus for a water closet having a toilet bowl and a normally closed flapper valve at the outlet of said bowl, an elongated tubular casing attached to the outlet end of said bowl and extending vertically downward therefrom, a macerating chamber formed in said casing below said bowl, a flexible pinch valve inside said casing below said macerating chamber for controlling the outlet from said macerating chamber, an intercepting chamber below said pinch valve, said casing having a discharge outlet and a discharge opening in communication with said intercepting chamber, a second pinch valve below said intercepting chamber for controlling the discharge from said casing outlet, a holding tank connected to said discharge opening, means for admitting flushing water into said bowl, means for closing said first pinch valve, means for opening said flapper valve to discharge water and waste matter into said macerating chamber, means for injecting a chemical into said macerating chamber to kill bacteria in said contained waste matter, means for injecting air pressure into said macerating chamber to cause the waste matter to be agitated and swirled into a slurry in said chamber, means for opening said first pinch valve to expel the waste matter into said intercepting chamber assisted by the air pressure in said chamber, means for opening said second pinch valve to discharge the waste material from the outlet of said casing, and means for closing said second pinch valve to optionally discharge said waste material out said discharge opening to said holding tank.
- 7. In a sewage treatment apparatus comprising an elongated casing having an inlet for the reception of sewage, a discharge opening and a discharge outlet, a macerating chamber adjacent the inlet end of said casing, an intercepting chamber adjacent the outlet end of said casing for intercepting the passage of said sewage through said discharge outlet and causing said sewage to pass through said discharge opening, a flexible first valve means in said casing at the bottom of said macerating chamber, a second flexible valve means at the bottom of said intercepting chamber, said intercepting chamber being located between said two valve means, means for introducing air pressure against said first valve means to close the same, means for introducing air pressure into said macerating chamber to cause agitating and turbulence of deposited sewage held in said macerating chamber, means for closing said second valve means and for opening said first valve means to deposit the treated sewage in said intercepting chamber, a holding tank and a conduit connection between said holding tank and said discharge opening, and means controlling said second valve means for optionally passing the sewage through the conduit connection to said holding tank by said air pressure when the second valve means is closed or through the outlet of said casing when the second valve means is open.
