Description

A SYSTEM FOR PURIFICATION OF DOMESTIC EFFLUENTS TECHNICAL FIELD The present invention relates to the purification of domestic effluents. More particularly, the invention provides a method and system for purifying effluents from a construction or groups of constructions that house up to several hundred families, such purification being sufficient for bath cleaning objects, and the allowed waste of excess water towards available drainage ducts, while eliminating biologically degradable solids.

TECHNICAL BACKGROUND Almost all sewage purification systems of the prior art require that sooner or later the system be closed to allow the removal of silt that has not been fully treated and has accumulated in the processing vessels. The large municipal treatment plants have the equipment and personnel to carry out this work. However, small-scale systems designed to be used in a single house or blocks of houses are best served by provisions that almost completely discard organic solids and therefore do not require such maintenance.

As is well known, the dispositions of the environment are becoming more and more strict, and the legal disposal of waste, whether as solids, liquids or even as gases, is becoming increasingly difficult and expensive. It is known that, apart from carbon dioxide and minor amounts of other gases, methane is produced during the decomposition of silt material. Typically, 0.35 m3 of methane becomes available per kilogram of decomposed slime. In the United States, the methane produced by cattle and expelled through their digestive systems, is considered such a detriment to the environment that Congress has given funds for research to see what, if anything, can be done about this. . Interestingly, methane has a higher calorific value than any other common fuel gas, except hydrogen. However, in almost all systems of the prior art, the methane generated is discharged into the atmosphere, causing an unpleasant odor. In some localities the municipal regulations prohibit the discharge of such gases. Methods and apparatus for treating domestic effluents are described in U.S. Patent Nos. 4,172,034 (Carlsson, et al.); 4,812,237 (Cawley); 5,114,586 (Humphrey) and 5,342,523 (Kuwashima). Carlsson describes an apparatus that operates on an easy-flow gaseous paste, having a dry solids content of between 1-15%, preferably 5-10%. Such dilute slurry unnecessarily extends the processing time to achieve aerobic degradation in a reaction vessel with aeration; however, the Calsson apparatus has the advantage of being compact. Humphrey describes a complex sanitation system provided with many containers, five of which have multiple air inlets. The resulting high air consumption necessitates the installation of a large air blower or compressor, leading to high operating costs and a problem of noise suppression. Another difficulty encountered in the Humphrey system is finding space in a residential construction for all the components of the system described. Cawley describes and claims a procedure to purify and recycle domestic wastewater, which consists of the steps of (a) collecting a first wastewater stream from domestic kitchen sources; (b) anaerobically digesting said first stream of waste water in a first septic tank; (c) collecting a second stream of waste water from domestic laundry and bath washing fountains; (d) combining the water of steps (b), (c) and (h); (e) anaerobically digesting the water from step (d) in a second septic tank; (f) pumping water from step (e) onto a biological sand filter under aerobic conditions; (g) pumping the biologically filtered water from step (f) through an ultrafilter, thereby separating the biologically filtered water into a stream of retained material and a penetrating stream; (h) returning said stream of material retained to step (d); (i) disinfect the current that penetrates; (j) returning a first portion of said current that penetrates disinfected domestic laundry and bathing facilities; (k) separating a second portion of said penetrating stream disinfected into a low salt portion and a high salt portion; (I) return the low-salt portion to a domestic kitchen; and (m) discard the high salt portion. Kuwashima proposes a pair of separator tanks which are used alternatively to separate floating or sediment material; the organic material is transferred for aerobic decomposition to a third tank. The device lacks the means to decompose large solids into small particles for efficient decomposition.

BRIEF DESCRIPTION OF THE INVENTION With this state of the art in mind, one of the objects of the present invention is to obviate the disadvantages of the small-scale effluent treatment systems of the prior art and to provide a system and method that internally removes organic solids to a degree that under normal use manual waste disposal will not be required in at least ten years of operation if it is required. It is a further object of the present invention to reduce the water consumption of a family in a construction provided with said system. This reduction is reflected not only in the charges for water use, but also in lower charges for sewage disposal, since the latter is often calculated as a proportion of water use charges.

DESCRIPTION OF THE PREFERRED MODALITIES 1 shows a system 10 for the treatment and purification of domestic effluent, and for the elimination of organic solid waste within said system. The separate drainage means 12, 14 are provided for separately collecting a first and second constituents of the sewage of a domestic residential unit. The toilet sewage comprises the first constituent of sewage, and the black sewage, shower, wash basin, laundry, and kitchen sink and the like comprise the second constituent of sewage. The drain means 12 is connected to the first valve means 16 which in turn is connected to the intake ports 18, 20 of a first and a second dual purpose container 22, 24. Each of these containers is also provided with two output ports 26, 28, 30, 32 and are identical to one another under construction. With the use of the first valve means 16 the containers 22, 24 are arranged to have alternate functions; during the period that the container 22, for example, acts as a collecting and settling tank, the remaining container 24 functions as an anaerobic reaction vessel for generating compost. The container 24 operates as an anaerobic reaction vessel when insulated by the first valve means 16 and 20, and performs a decomposition process during which the volume of slime 34 contained therein is greatly reduced. The upper outlet port 32 consisting of a one way valve (not shown), is used for the removal of combustible gas 36 generated during the decomposition process. The use of the gas 36 will be described with reference to Figure 2. A gas-proof loading door 38 is provided in the containers 22, 24 so that the biologically degradable material, for example animal excrement, can be charged during the ignition . The first valve means 16 directs the first constituent of sewage to any of the dual purpose containers, 22 in the present example, which is currently used as a collection and settlement tank. The first valve means 16 are operated when a substantial amount of solids has accumulated in the container 22 which is currently being used as a collecting and settling tank. The period between successive operations of valve means 16 exceeds one year, and is typically three years, under normal operating conditions. An aerobic reaction vessel 40 is connected to receive an aqueous slurry containing floating organic solids from the collection and settlement tank 22. The solid content therein is maintained at 15-35%, the reaction being carried out at a temperature between -6 ° C to 92 ° C. The water paste remains in a flowable constitution.

An aerator 42 is connected to the container 40 to oxygenate the slurry. The high solid content established makes an efficient aeration. The allowed wide temperature scale corresponds to the survival temperature of active bacteria that causes the decomposition of organic waste. The first pumping means 44, such as a centrifugal immersion pump, repeatedly pushes the slurry from the aerobic reaction vessel through aerator 42 to maintain oxygen in the vessel 40 at at least 1 ppm. The first pumping means 44 is at least partially energized by the gas generated in the anaerobic reaction vessel 24. Advantageously, the first pumping means 44 are arranged to cause a vigorous stirring to effect a size reduction of the suspended solids in the watery paste. A simple method to achieve this end is to use a powerful pump motor and pump the pump at a speed of more than necessary in relation to the requirements of only aeration. A separating vessel 46 receives aerated and bio-aerobic reacted slurry from the aerobic reaction vessel 40. Additional settlement and aggregation of solid particles takes place in this vessel. A slurry pump 48 capable of handling such material transfers the same through the second outlet means 50 provided for pumping such particles from the separation vessel 46 through the first valve means 16 to the collection and double settler vessel. purpose 22, in the example shown. A first filter outlet 52 is provided for removing purified water from the separation vessel 46. Advantageously, the filter 54 is provided with means for automatically clearing filter plate locks. The quality of the purified water is determined by the quality of the filter unit 54. A lower storage vessel 56 connected to the drain means 14 receives the second constituent. An upper storage container 58 provides water for washing the bath. The container 58 is fed by means of the second pumping means 60 which transfers water from the lower storage container 56. The water in excess of that required for washing the bath is purified sufficiently to be passed to the drain 62. If the container 58 requires more water than that provided by the system at any particular time, then additional water may be provided to the upper storage vessel 58 from the main water (not shown). With reference to the rest of the figures, similar reference numbers have been used to identify similar parts. Referring now to Figure 2, there is seen a detail of the same treatment and purification system 10 described with reference to Figure 1.

The gas 36 is produced in the dual-purpose containers (only one of which, 24, is shown) and is collected in the tank 64, compressed in the compressor 66, stored in the tank 68 under compressed pressure, and used at least in part to energize the first pump means 44 which drives the slurry through the aerator 42. The system 10 operates in this way while requiring less electricity, and more importantly in urban areas, reduces the generation of unpleasant odors . The primary component, typically 57-67% of the gas generated, is methane. The rest is almost all carbon dioxide. The calorific value of such gas mixture is from 5000 to 6500 kcal / cubic meter. The compressed gas is fed into an internal combustion engine 70 which has improved protection against internal corrosion. The motor 70 is connected to the first pumping means 44 which in turn is also connected to be driven by an electric motor 72 when the gas 36 is not available for any reason, for example during the direction. Alternatively, or in addition to, said gas can be converted to electricity, or be used in an incinerator to heat water directly. Figure 3 shows a detail of a second embodiment of a purification system 74 having components for reducing the size of solids contained in the first constituent of sewage. The pumped slurry is repeatedly struck against an arrangement of stationary cutter blades 76 to effect size reduction of the suspended solids in the slurry that moves around the aeration circuit. The particle size is thus advantageously reduced to a size of up to 1.5 millimeters, the resulting increase in surface area of exposed solids leads to effective aeration. Seen in Figure 4 is a detail of a third embodiment of a purification system 78 provided with additional filter means. The water outlet port 80 of the lower storage vessel 82 is connected to a filter 84 for the removal of solids from the water passing through it. The water that passes the filter is stored in the upper storage vessel 86 and used for washing the bath. Excess water is available for horticultural objects 87. Although there is no objection to the inclusion of small solids for bath washing, it is however advantageous to remove such solids to avoid a malfunction of the washing tank mechanism 88. With reference now to Figure 5, part of a preferred embodiment of a purification system 90 having a special arrangement of the upper storage container 92 is seen therein. An upper storage container 92 is provided with a first water receiving container 94 having an edge open top 96. The water in the container 94 includes fats, soaps and detergents that originated in the second constituent of sewage. A pump 97 agitates the water in the container 94, and causes foaming. The foam 98 floats on the water in the container 94, and together with the overflow water therein, flows downward towards the tank 100. The overflow water and the foam 98 are removed from the tank 100 as needed to bathroom wash. Shown in Figure 6 is a mode that generates electricity through the use of a water turbine 102. A treatment and purification system 104 generates electricity for use in the system, by means of a turbine 102 in a water pipe 106 that exits of the upper storage container 108. Rechargeable electric batteries 110, connected to a pump motor 112, provide storage energy, so that the first pumping means 44, seen in Figure 1, can be operated when the gas or the stream Main electric are not available. In additional modalities (not shown) the supplementary energy is generated by solar cells or by a windmill, the choice depending on which is the most suitable for the location in which the system is going to be installed. Referring now to Figure 7, there is described a detail of one embodiment of the treatment and purification system 116 having provision for silt transfer 34. The first and second dual purpose vessels 118, 120 are provided with an additional outlet 122, 124 to receive, and an additional lower outlet 126, 128 to discharge sludge 34 that accumulates in the lower part of the containers 118, 120. Each container is provided with a pump 130, 132 capable of handling such material. The silt transfer is effected from the dual purpose vessel (eg 122) to be used for storage and settlement to the vessel (124 in the present example) to be used for anaerobic decomposition. In the present embodiment the activation of the appropriate pump (130 in this example) is effected through a control panel 134 and triggered automatically by the movement of the first valve means 136. Referring now to Figure 8, a block diagram representation of a system 138 is shown consisting of means 140 for separately collecting at the source a third cooking water constituent 142 which is passed through a detachment unit 144, which can be either a static or dynamic filter unit for separating organic components and other waste 146 from it. In said figure the remaining components are the same as those described with reference to figures 1 and 2. As will be realized, water leaving the filter and settlement unit 46 and entering the storage 56 can not only be recycled by pump 60 for use in the toilet, but can also leave the system to be available for other uses, depending on the purity of the water. As stated here above, such an arrangement allows the effective use of waste disposal units installed in kitchen sinks.

In this embodiment the double-purpose container 24 is provided not only with anaerobic bacteria, but also with cellulose-consuming bacteria such as Trichonympha, which can function in conjunction with said anaerobic bacteria without any interfering with the other. Figure 9 describes a part of an additional system 86, similar to that described above with reference to Figure 1, however, it accelerates the anaerobic decomposition process. An anaerobic decomposition reactor 88 is provided with a triple spaced wall 90, 91, 92, which forms two concentric outer compartments 93 and 95 around each of said containers 88 for the introduction therein of fluids to regulate the temperature inside said containers. Preferably, the compartment 93 adjacent to said container 88 is filled with an oil fluid 97 and the compartment 95 is connected via intake and outlet passages 98, 99 to a source 94 of aqueous fluid 96 for heating the reactor 88, whose fluid is heated by a heat source 89. The heat can be provided either electrically, or by incinerating a fuel, suitably some of the methane 74 produced in the reactor 88. The heating of the reactor 88 accelerates the decomposition process and also allows the decomposition of materials that do not disintegrate significantly at room temperature. This arrangement is also preferred for systems installed in cold climates. Further, the decomposition rate within the reactor 88 can be regulated by controlling the temperature of the aqueous fluid 96 introduced into the compartment 95, which aqueous fluid then serves to heat or cool the oil fluid 97, which in turn warms or cools the contents of the reactor 88, the hot water being removable from the compartment 95 and being replaceable by cooler aqueous fluid as desired, optionally using additional inlet and outlet ducts (not shown). It should be noted that the conduits interconnecting the various components of the system and coming out of it can be formed as double-walled conduits and the system can additionally comprise means for introducing hot water between the inner and outer walls of said conduits to heat the conduits. contents of the fluids that flow through them. In addition, the gas produced in the reactor 88 can be fed to an incinerator to heat water to be circulated between the inner and outer walls of said ducts, whose heated water can also be introduced under pressure into said ducts to rinse them when necessary. It will be apparent to those skilled in the art that the invention is not limited to the details of the illustrative embodiments mentioned above and that the present invention may have modalities in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the aforementioned description, and all changes that come within The meaning and scale of equivalence of claims are therefore designed to be encompassed by them.
