Description

Regional wastewater treatment unit {APPARATUS FOR TREATING WASTE WATER ON SITE}

The present invention relates to a regional wastewater treatment apparatus, and relates to a regional wastewater treatment apparatus that purifies and treats wastewater and spouts it to supply water to the soil.

For decades, it has been recognized that proper disposal and disposal of people's waste is essential to prevent the spread of germs. The first method used to prevent human droppings from contaminating surface water or passing through insects was to use deep holes or outdoor toilets. These facilities, even if smelled, were effective at removing bacteria and viruses.

If human waste is directly in direct contact with the surface water, the findings show that no more than nine feet away from the toilet wall, no bacteria or viruses associated with human waste are found. Thus, it has been found that soil provides a reliable natural filter for removing contaminants. Accordingly, there has been a succession of inventions relating to septic tanks and reservoirs where a facility using flowing water to remove contaminants is permitted. Conventional septic tanks and basin treatment systems consist of closed anaerobic storage tanks that allow separation of flotation by oil, resin (fat), wax and soap and removal of solids by precipitation. However, in the case of septic tanks, it was recognized that only 40 to 50% of the waste introduced was removed and the bacteria or viruses were not properly removed. Thus, most of the treatment takes place at the sump of the septic tank system. In order to provide effective treatment at the reservoir, aerobic (oxygen) conditions must be provided in the water for the microorganisms to remove the waste. If flooding occurs in a reservoir for a relatively short period of time, the beneficial microbes will die from lack of oxygen. As a result, the soil is devastated by waste filtered from water and not mineralized by microorganisms. This is called septic tank failure.

The septic tank should remove the floats and solids every 7 to 10 years in order to prevent the floats and solids from entering the reservoir and disturbing the operation of the reservoir. In fact, septic tanks rarely fail to perform these functions. These failures occur at the sump when solids, oils, resins (fats), waxes or soaps enter the basin through the septic tank.

A common cause of reservoir failure is flooding due to overloading of the reservoir beyond the capacity of the reservoir used capacity. This results in flooding the reservoir and killing the microorganisms needed to treat the wastewater in the septic tank. Once the microorganisms die, soil deterioration occurs rapidly, leading to failure of the septic tank treatment system.

The prior art has made modifications to the components of the septic tank and basin treatment system, but did not represent a fully synergistic on site wastewater circulation system as the present invention. The basic difference is that modifications of the prior art require the use of chemical feeds, routine replacement of the components or frequent adjustment or purification. Control systems for prior art modifications to conventional septic tanks and drainage systems are sometimes very complex, costly to make initial installations, and require a qualified repairman for repair or adjustment.

As an example, U.S. Pat.No. 5738781 modified the septic tank to include charcoal in the chamber and surface, but the processing capacity was not much improved. US Patent No. 5707513 used foam cells for use with conventional septic tank wastewater. U.S. Patent No. 5645732 used a U-shaped filter with a fiber filter material between the inside and the outer shell, which requires a periodically changing polymer filter material. U.S. Patent No. 4824572 used a multi-media filter consisting of gravel, limestone, straw or reed and composed of chlorinated hay. US Patent No. 4100073 used a closed sand filter with a septic tank, storage chamber and disinfection section. US Patent No. 4826601 uses a first anaerobic cell, followed by anaerobic precipitation, a third cell eluting through a porous anaerobic medium, followed by a fixed cell, and a sand or dolomite bed. Temporarily interrupted, followed by a drain, and additional alum or methanol is added to the first cell. US Pat. No. 4971690 uses a septic tank, passes through a chlorine contact chamber (chemical feed), an underground natural filter media reservoir, collects wastewater discharged by the drainage system, and collects water for irrigation purposes. Pump up. U.S. Patent No. 3933641 consists of a septic tank, which is passed through a splash pan, a second filter, a storage tank, which is evenly divided into waste water by a mobile filter, chlorinated, sprayed on the surface or Provided is a processing and circulation system arranged by other means. US Patent No. 4599167 provides for the construction of an anaerobic digester with packaging medium that recycles and generates methane for wastewater treatment. US Patent No. 4895645 uses closed multi-chamber, multi-media, biological filter tanks with complex control structures between septic tanks and reservoirs, but provides synergistic use of most or multiple treatment cell types of the present invention. I never do that.

The present invention has been presented to solve the above problems, and an object of the present invention is to provide a regional wastewater treatment apparatus.

In order to achieve the above object, the regional wastewater treatment apparatus according to the present invention is a regional wastewater treatment apparatus that purifies and treats wastewater, and is discharged to the outside to supply water to the soil, and an inlet connected to the main supply line of the wastewater.

A preferred embodiment of the present invention, as shown in FIG. 1, has two or more internal chambers (commonly used in the technical field to which the present invention belongs), and a main feed of wastewater flowing out of a house or a shopping mall. A septic tank 10 having an inlet connected to the line is provided. The outlet of the septic tank 10 is connected to a standard sewer line of the type that is connected to the inlet of a wetland rock plant filter 12. The wetland lock plant filter 12 is implemented according to standards in the technical field to which the present invention belongs. The outlet of the wetland lock plant filter 12 is connected to a standard sewer line of the type which is connected to the inlet of a dosing tank 14. The dosing tank includes one automatic inverted suction tube for vibrating the planted shallow aggregate filter. The outlet of the dosing tank 14 is connected to a standard sewer line of the type which is connected to the inlet of a pulsed planted shallow aggregate filter 16. The outlet of the pulsed planted shallow aggregate filter 16 is connected to a standard sewer line of the type which is connected to the inlet of the treated wastewater storage tank 18. Within the treated wastewater treatment tank 18 are included commercially useful pumps and pipes that are connected to the inlet of the wastewater jetting apparatus 20. The outlet of the wastewater jetting apparatus 20 is connected with a sprayer nozzle of the type and type required for the wastewater jetting apparatus, or, optionally, the wastewater is disposed or stacked by other desirable means such as direct system discharge. It is discharged to a raised drain, treated for other uses, or recycled.

Another implementation of the present invention is to have a plurality of the devices or a plurality of components of the device to operate simultaneously or sequentially. This implementation enables devices that are larger, treat larger amounts of wastewater, and produce the discharge water quality required for a particular application.

All components used in the present invention are disclosed by other prior art, except for a shallow pulsed planted aggregate horizontal flow filter. Many such components, such as septic tank 10, dosing tank 12, treated wastewater storage tank 18, and wastewater jetting apparatus 20, are readily available from commercial sources. The wetland lock plant filter 12 and the pulsed planted shallow aggregate filter 16 are structures that must be installed on site. There are many references to the implementation of a rock plant filter. Although all references to these prior art references, except for the individual components of the present invention, are not shown for the overall synergetic apparatus according to the present invention, they are not shown as countercurrent, chemical feed or cycle. It is not shown for planted shallow horizontal aggregate filters, such as tertiary filters, which do not require extensive cleaning. Aerobic conditions, produced by a planted shallow aggregate filter and paired with the roots of plants that inhale nutrient water during the flow of vibrations, produce an organic synergy similar to a rock plant filter. The wetland lock plant filter, however, continuously stores water while continuously creating anaerobic conditions within the low level wetland lock plant filter. Conversely, the planted pulsed aggregate filter is continuously aerobic through the outside, and any water other than the moisture on the surface of the mineral aggregate in the growth of microorganisms and at the root of the plant is continuous. Do not save as.

Wetland lock plant filters 12 are implemented by placing suitable sized and graded rock media in a narrow, rectangular ditch having a size and length sufficient for planting selected aquatic plants. The rock plant filter should be able to maintain the depth of the liquid by approximately two thirds of the total media depth even without flow. The total lock depth should be at least 18 inches. The minimum width of the lock plant filter should be 2 feet and the volume should be at least 210 square feet, measured from the reverse of the outlet. In defined areas, there is a problem that rock plant filter ditches for surface water must have an impermeable membrane. The 210-square-foot filter is sized to be designed to lift 400 gallons of daily household waste. The total volume needed to raise more volume should be increased by 50 square feet for each 100 gallons per day or these units. In order to prevent the obstruction or flow in the filter medium from changing, the inlet line from the septic tank 10 must go 10 feet into the filter and be covered. The part of this pipe must be perforated and placed at the liquid level on the opposite side of the pipe.

The pulsed planted shallow agglomerate filter 16, as shown in FIG. 2, has an appropriately sized mineral aggregate located in a four-sided rectangular trench with a continuous impermeable membrane 19 at the bottom. (24) constituted by a medium, the impermeable membrane extends above the ground level to prevent surface water wastewater from flowing into the mineral aggregate medium 24 of the filter. The inlet and outlet pipes pass through the impermeable membrane 19 opposite the filter and are sealed to prevent ingress of surface water. The inlet pipe is connected to an influent distribution header 15. The inlet split header 15 extends the entire length to the end of the pulsed planted shallow aggregate filter 16 and is implemented as a pipe covered with solid ends at both ends, and the inlet of the wastewater is pulsed planted shallow A plurality of holes are included in the side wall of the pipe to divide evenly across the width of the aggregate filter 16. The split header is located above the impermeable membrane 19 at the bottom above the bed of mineral aggregates to assist in the split ingress. The pulsed planted shallow aggregate filter 16 is implemented in dimensions suitable for the amount (gallons per minute) imposed by the dosing tank 14. Liquid is completely drained from the pulsed planted shallow agglomerate filter 16 between pulses from the dosing tank 14. The drainage from the inlet split header 15 is a pulsed planted shallow aggregate filter ( By flowing the bottom of 16, it extends from the inlet split header 15 to an effluent collection header 17. The form of growth of aerobic microorganisms on the mineral aggregate 24 medium increases treatment efficiency. Maintaining aerobic conditions within the filter aggregate media 24 is critical to the subsequent associated processing behavior. The wastewater collection header 17 is independent of the implementation of the inlet split header 15, but the pulsed planted shallow air surrounded by the mineral aggregate 24 to ensure drainage between the pulsed loading cycles. The discharge of the grease filter 16 is lowered.

FIG. 3 shows a sectional view of the preferred pulsed planted shallow aggregate filter 16 shown in FIG. 2. The inlet split header 15 is virtually represented in the mineral aggregate medium 24, which is an impermeable membrane 19 at the sides and bottom of the pulsed planted shallow aggregate filter 16. Is separated from the soil. The impermeable membrane 19 extends over the existing finished ground of the surface to prevent surface water from flowing over. The mineral aggregate medium 24 is separated from the top soil 22 using the permeable separator 21 by the full length and width of the pulsed planted shallow aggregate filter 16. The soil upper layer 22 is planted with the selected plant 23 by the total width and length of the soil upper layer 22 covering the entire width and length of the pulsed planted shallow aggregate filter 16.

Depending on the variety of terrain and the variety of capacities of the device, a pump P and a pump control device are required for proper operation between the components shown in FIG. Such pumping devices are not essential for the proper treatment of wastewater, but installation will be required if the terrain does not allow the flow of gravity through the device. Changes in the size of the components used and the mineral aggregates in the apparatus will vary depending on the qualitative and quantitative design capacity of the wastewater treatment apparatus.

Operation of the regional wastewater treatment apparatus according to the present invention is as follows.

Wastewater flows into the septic tank 10 from a house or a shopping mall. The septic tank separates the solids from the wastewater and breaks down anaerobic bacteria by organic matter. The purpose of the septic tank is to separate oils, resins (fats), waxes and soaps by means of baffles located at the inlet and outlet of the tank, whereby these suspended solids are stored and suspended solids are stored. To rise to the surface of the fluid in the tank, providing a suitable retention time of anaerobic conditions for settling to the bottom of the septic tank. In septic tanks, all of the precipitated and mineralized solids and oils, waxes, resins (fats) and soaps are partially mineralized while they are physically removed by the septic pump pumping contractor every 7 to 10 years. The septic tank removes about 40-50% of the suspended solids and biochemical oxygen demand of the entire wastewater treatment plant.

Wastewater from the septic tank 10 flows into the wetland lock plant filter 12. Wetland lock plant filter 12 reduces BOD, toxic organic chemicals, heavy metals and radioactive materials through anaerobic / aerobic biological processes. In warm climates, planted wetlands rock filters have little or no outflow of drainage by evapotranspiration. Experiments with rock plant filters have been conducted consistently for a period of six years or more, with 5 mg or less of BOD per liter, less than 10 mg of suspended solids per liter, and 98% or more of bacteria removed.

Waste water from the wetland lock plant filter flows into the dosing tank 14. The dosing tank collects wastewater until it is full. The dosing tank fills the pulsed planted shallow aggregate filter 16. The pulsed planted shallow aggregate filter discharges the wastewater to the wastewater storage tank 18 by gravity. Wastewater from the experiments of the pulsed planted shallow agglomerate filter has a 98% removal rate of bacteria, suspended solids and BOD compared to the pulsed planted shallow agglomerate filter 16.

The wastewater flows into the treated wastewater storage tank 18 and is stored as required by the wastewater jetting apparatus 20 or the arrangement means. After completing the treatment, the wastewater has the same or better water quality than the water flowing on the surface by rain. Wastewater jetting devices are devices for watering grass or trees, which are typically installed in residential neighborhoods. When the timer or control means sends an operation signal to the jet device, the jet device pulls the waste water from the treated waste water storage tank 18 to the drain nozzle of the jet device 20. Under these conditions, the wastewater is sprayed over a suitable surface and placed by evaporation, absorption and inhalation of plant roots. Every time the dryer or emissions are low, the grass can be irrigated by producing water from other sources. In small social systems, wastewater can be used for cultivation or roadside roads.

The device according to the present invention is a synergistic device. Treatment units are not individually effective enough, but when connected, allow for the local treatment of wastewater and the placement of wastewater in areas that cannot be treated or are not suitable or failed. The device according to the present invention is also environmentally friendly, as it reuses the water consumed and easily heals the failed areas in conventional drainage.

As described above, the present invention is intended for the natural treatment of wastewater to have a purity of at least 99.5% without the use of non-chemical feeds, consumables and reliable frequent maintenance process steps. Provide all synergistic artificial conditions. In addition, the device according to the present invention is simple to design and operate, economical to implement, operate and maintain, provides nearly complete disposal of wastewater, provides the conditions required by nature, replaces an existing failed septic tank drain system or It is suitable for implementing systems on the ground that do not provide the necessary conditions for the proper functioning of conventional septic tank basins.

In other words, the regional wastewater treatment apparatus according to the present invention,

Firstly, it is useful for soil or high water surface, which is unsuitable for the conventional septic tank and drainage system,

Second, using natural treatments and facilities that co-operate with wastewater treatment,

Third, high reliability can be obtained with low maintenance cost,

Fourth, meet or exceed enforcement standards or requirements,

Fifth, make the land unusable,

Sixth, installation and operation are relatively inexpensive, compared with other wastewater treatment standard means in areas with poor soil properties,

Seventh, to conserve water and energy,

Finally, it provides on site wastewater treatment facilities that do not require chemical feeds or operators for routine monitoring and regulation.
