Abstract

A sewage treatment system particularly adapted for use in small boats, in which an additive for treating the sewage is stored in dry form, such as in tablets, in a tank separate from, but in communication with, the sewage treatment chamber. Flushing a toilet associated with the system automatically activates a water pump and causes water to be pumped from a separate source into the additive tank, dissolve a portion of the additive and flow, such as by gravity, from the tank into the treating chamber. At the same time a combination macerating and mixing unit is energized to reduce solid sewage to at least a maximum particulate size and vigorously mix and remacerate the reduced sewage with the dissolved additive flowing from the tank into the chamber.

Claims

1. A system for treating sewage comprising a sewerage treatment chamber free from baffles and the like whereby sewage may travel directly from the inlet to the outlet thereof, conduit means for discharging an effluent containing solid sewage contaminants into said sewage treatment chamber, said conduit means including first rotatable impeller means for macerating the effluent and means for restricting the discharge of the macerated effluent therefrom so that only particles having a size smaller than a predetermined maximum size may be discharged therefrom, a tank containing sewage treatment tablets, second conduit means for delivering a liquid substantially free of particulate material to said tank whereby a portion of the sewage treatment tablets will be dissolved in the liquid, means for discharging the liquid including the dissolved portion of the sewage treatment tablets into said sewage treat-ment chamber wherein the dissolved portion of the sewage treat-ment tablets will treat the sewage contaminants contained therein, second rotatable impeller means located within said sewerage treatment chamber for remacerating the effluent, and means mounting said first and second rotatable impeller means on a common shaft for conjoint rotation.

2. A system for treating sewerage according to claim 1, wherein said second impeller means comprises a helical flight selectively configured for directing the contained effluent to flush the sides of said treatment chamber.

3. A system for treating sewerage according to claim 1, wherein said second impeller means comprises a plurality of blades extending radially outwardly from a rotatable shaft.

4. A system for treating sewage according to claim 1 further including motor means for concurrently energizing said first and second impeller means.

5. A system for treating sewage according to claim 1 further comprising third conduit means for discharging the treated effluent from said sewage treatment chamber wherein the inlet port of said third conduit means is spaced from the bottom of said sewage treatment chamber.

6. A sewage treatment system as recited in claim 1, wherein:

said tank is positioned above said sewage treatment chamber; and

the bottom wall of said tank has openings therein communicating with the said sewage treatment chamber.
