Example Embodiment

[0083] Specific Example 1

[0084] The following describes a waste disposal system that can be emulated. A mechanical filter screen made by welding flat steel bars of 1 / 4 inch x 2 feet. The spacing between the flat steel bars of one filter screen is 3 / 4 inches, and the interval of the second filter screen is 3 / 8 inches. . The collection tank consisted of the bottom half of a 1500 gallon concrete tank, purchased from Montano (Santa Fe, NM). By placing a 1 / 4 inch steel bar in the middle of the concrete pool, the concrete pool is divided into two equal parts. A 30-degree "V" notch weir was cut into dividing plates, allowing the decay to flow from one side to the other. The larger strip filter screen is placed on the right side of the pool and the smaller strip filter screen is placed on the left side or the input side of the concrete pool. The collection tank is in fluid communication with the equalization tank, which is constructed on-site using stable local soil, and 30 mil PVC c...

Example Embodiment

[0107] Specific Example 2

[0108] An exemplary waste treatment system includes a mechanical filter screen device in fluid communication with one or more collection tanks through a fluid conduit. The fluid collection tank is in fluid communication with an equalization tank of approximately 200 cubic meters through a fluid conduit. The equalization tank has a network of PVC piping systems with a diameter of 50 mm, with a spacing of 50 cm and fluid communication with a blower / air compressor, which can provide about 0.9 cubic meters / min / 100 cubic meters of received decay and / Or domestic sludge. The blower is controlled by a timing device and a low float. The equalization tank is in fluid communication with 4 reed bases through 4 PVC sleeves with a diameter of 75mm, which is equipped with 4 1.0-2.0 horsepower inflow pumps. The transport of decay is controlled by a timing device, which strengthens each of the 4 pumps in series. The distribution of the decay on the surface of the ree...

[0113] Specific Example 3

[0114] Figure 20 shows a block diagram of a waste treatment system for treating domestic sludge and / or decay. The waste treatment system 500 includes a centrifugal separator 510 in fluid communication with an equalization container 520 through a fluid conduit 515. The centrifugal separator 510 is operated to remove inorganic and organic solids from the spoilage before delivering it to the equalization vessel 520. The rest of this article discusses the functions of the equalization vessel for illustration, such as ventilation and mixing. The equalization container 520 is in fluid communication with the hyacinth lagoon 530. The hyacinth lagoon 530 is in fluid communication with the trickle biofilter 540 through fluid conduits 545 and 546. As discussed in other parts of this article, trickle biofilters are operated for nitrifying fluids. The Hyacinth Lagoon 530 is also in fluid communication with the constructed swamp 550 through a fluid conduit 547. As ...

Abstract

Waste treatment systems and methods of using them to treat septage, domestic sludge or both are disclosed. Certain examples provided herein relate to waste treatment systems that include a plurality of stages, such as, a plurality of ecosystems, configured to treat domestic sludge, septage or both.

Description

technical field [0001] Certain embodiments of the present technology relate to waste treatment systems configured to treat septage, domestic sludge, or both, and to methods of making and using such systems. More specifically, certain embodiments of the present technology relate to domestic sludge and septage treatment systems including numerous ecosystems. Background technique [0002] The cost effectiveness of the design of a treatment system for sludge and septage produced in the suburbs and towns of the United States is a very challenging design problem. Treatment technology depends on high-energy mechanical systems, such as sequencing batch reactors, activated sludge systems, or oxidation ditches, which are often expensive to operate (e.g., approximately $8.5-20.00 per 1000 gallons of septage and sludge) . For example, reference may be made to "Land Application of Municipal Wastewater", US Environmental Protection Agency, 1980, Tables 8-6. Activated sludge treatment s...
