Abstract

Abstract A method and apparatus for treating and disposing of sewage which includes introducing raw sewage into a liquid separator. Separating liquid sewage from the solid sewage and collecting the separated liquid in a collection reservoir. The solid sewage is passed onto a filtration conveyor where the carry over liquid is filtered by the conveyor into a filtration reservoir and the solid sewage is transported to an incinerator. The liquid in the filtration reservoir is recirculated to the collection reservoir. Air supply and diffusion device introduces diffused air into the liquid in the collection reservoir to carry suspended solid sewage therein to the surface of the liquid in the collection reservoir. The liquid and solid sewage on the surface of the collection reservoir is passed over a weir onto the filtration conveyor where the filtration, transportation, recirculation and incineration steps are repeated. The diffusion of air into the liquid, the passing of the liquid and the solid sewage onto the filtration conveyor and the recirculation of the liquid is continued for a set period of time after the raw sewage has stopped flowing into the separator. At the termination of the recirculation cycle, the liquid is passed from the collection chamber through baffles into an effluent reservoir where the liquid is treated to reduce the bacteria count.

Claims Analysis

Total Claims: 10

Claim 1

Independent Claim 52 words

The method of treating sewage of claim 1 including recirculating the liquid from said filtration reservoir into said collection reservoir and diffusing air into said liquid in said collection reservoir for a period of time sufficient to allow the oxidation of a portion of the suspended organic solid sewage in said liquid.

Claim 2

Dependent Claim 56 words

The method of treating sewage of claim 2 wherein after said recirculation of said liquid from said filtration reservoir to said collection reservoir has been terminated, said liquid in said collection reservoir is passed into a baffle chamber, wherein said liquid flows over a weir at the top of said baffle chamber into an effluent reservoir.

Claim 3

Dependent Claim 28 words

The method of treating sewage of claim 3 wherein the liquid in said effluent reservoir is treated with a chemical for lowering the bacteria count of said liquid.

Claim 4

Dependent Claim 38 words

The method of treating sewage of claim 4 wherein the liquid in said effluent reservoir is held in said reservoir for a period of time after introduction of said chemical for lowering the bacteria count of said liquid.

Claim 5

Dependent Claim 39 words

The method of treating sewage of claim 5 wherein the liquid in said effluent reservoir is pumped from said effluent reservoir and passed through an ultra-violet ray means for treating said effluent liquid to further reduce the bacteria count.

Claim 6

Dependent Claim 193 words

SewAge treatment and disposal apparatus including a liquid collection chamber; a liquid separator mounted on said collection chamber, said separator being connected to receive raw sewage influent and having perforations allowing liquid sewage to drain from said separator into said collection chamber; a filtration conveyor for receiving solid sewage and carry over liquid sewage from said separator; said conveyor having a porous surface to filter the liquid sewage and support and transport the solid sewage; incinerator means receiving and incinerating the solid sewage received from said conveyor; a filtration chamber below said filtration conveyor receiving the liquid filtered through the porous surface of said conveyor; recirculating pump means for recirculating the liquid from said filtration chamber into said collection chamber; air diffusing means supplying and diffusing air in said collection chamber to oxidize suspended organic solids and to carry suspended sewage solids to the surface of the liquid in said collection chamber; a weir between said collection chamber and said filtration chamber for the liquid and solid sewage on surface of said liquid in said collection chamber to flow onto the filtration conveyor for incineration of solid sewage and filtering of said liquid.

Claim 7

Dependent Claim 68 words

The sewage treatment apparatus of claim 7 wherein said apparatus includes a baffle chamber adjacent said collection chamber, valve means disposed between said baffle chamber and said collection chamber; a weir adjacent the top of said baffle chamber for allowing the liquid therein to flow from said baffle chamber; operating means for opening said valve means after said recirculation of liquid by said pump means has been terminated.

Claim 8

Dependent Claim 49 words

The sewage treatment apparatus of claim 8 wherein said valve means includes an elongated plug valve, said valve having an elongated cylindrical plug with an elongated longitudinal slot for allowing liquid to flow from said collection chamber to said baffle chamber when said plug is in the open position.

Claim 9

Dependent Claim 49 words

The sewage treatment apparatus of claim 8 wherein an effluent reservoir is disposed adjacent said baffle chamber to receive the liquid as it passes over said baffle chamber weir, said effluent reservoir having means for introducing a chemical into said liquid for reducing the bacteria count of said liquid.

Claim 10

Dependent Claim 25 words

The sewage treatment apparatus of claim 8 wherein said filtration conveyor includes a series of overlapping porous grates mounted obliquely on a continuous chain belt.
