Description of drawings

FIG. 1 is a cross-sectional view schematically showing the structure of a toilet sanitary system of the present invention.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention clearer, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described in the specification are only used to explain the present invention, and are not used to limit the protection scope of the present invention.

FIG. 1 shows a schematic structural diagram of a toilet sanitary system of the present invention. The toilet system is especially suitable for use in areas where no sewers are laid, for sewage treatment and water purification in household toilets. As shown in FIG. 1 , the toilet sanitary system generally includes a toilet 1 , a septic tank 3 , a sewage conveying pipe 5 and a sewage cleaning pipe 9 . The septic tank 3 has a cylindrical shape or a spherical dome shape, and is entirely embedded in the microbial degradation soil layer 4 .

The sewage conveying pipe 5 passes through the microbial degradation soil layer 4 and extends into the inner space of the septic tank 3 . When the dirt in the septic tank 3 accumulates to a certain amount, it is cleaned and transferred to the outside through the cleaning pipe 9 . The microbial degradation soil layer 4 contains various microorganisms that can degrade ammonia nitrogen, COD, BOD and SS in the sewage.

A first porous separator layer 13 and a second porous separator layer 14 spaced apart from the first porous separator layer 13 are provided in the upper half of the inner space of the septic tank 3 . The second porous separator layer 14 is located above the first porous separator layer 13 . The inner diameter of the holes on the second porous separator layer 14 is smaller than the inner diameter of the holes on the first porous separator layer 13, so that the first porous separator layer 13 and the second porous separator layer 14 have a negative impact on the fecal waste. The floating solids are subjected to two-stage blocking and filtration to obtain initially filtered sewage. The inner diameter of each hole on the first porous separator layer 13 is 20-100 mm, and the inner diameter of each hole on the second porous separator layer 14 is 5 mm-15 mm. Both the first porous separator layer 13 and the second porous separator layer 14 are made of corrosion-resistant materials, such as polymer composite materials or ceramics.

A porous block containing aerobic bacteria is provided between the first porous separator layer 13 and the second porous separator layer 14 . Aerobic bacteria include, for example, spores, actinomycetes, and yeasts. The porous mass may be made of corrosion-resistant porous materials such as zeolites, volcanic rocks, ceramic blocks, sintered sludge particles, and the like.

The outlet end of the sewage conveying pipe 5 is connected to the guide tube coil 17 , and the guide tube coil 17 is located under the second porous baffle layer 14 . The guide tube disk 17 is generally in a helical shape, and FIG. 1 shows the guide tube disk 17 in a "return" shape. It should be noted that the shape of the guide tube disk 17 is not limited to the reverse shape, and other shapes of the guide tube disk 17 can also be used. The sewage enters the guide coil 17 from the toilet 1 through the sewage conveying pipe 5. The guide coil 17 of this structure can prolong the residence time of the sewage in the conveying pipe and/or delay the falling of the sewage into the septic. tank 3, so that the dirt in the septic tank 3 can be more fully fermented and/or degraded.

After the fermented and/or degraded waste enters the septic tank 3, the solid matter naturally settles to the bottom. As the accumulation of solid substances increases, the solid and liquid are layered, and the sewage first passes through the first porous separator layer 13 and enters between the first porous separator layer 13 and the second porous separator layer 14, The aerobic bacteria between the porous separator layer 13 and the second porous separator layer 14 degrade the organic matter in the sewage. The degraded sewage passes through the second porous separator layer 14 and is discharged into the microbial degradation soil layer 4 through the sewage outlet 10 .

A porous block containing anaerobic bacteria is arranged below the guide tube disk 17 and at the bottom of the septic tank 3 . The anaerobic bacteria are used to ferment the solid substances settled at the bottom of the septic tank 3, and the anaerobic bacteria include, for example, photosynthetic bacteria, lactic acid bacteria, yeast and the like. The porous mass may be made of corrosion-resistant porous materials such as zeolites, volcanic rocks, ceramic blocks, sintered sludge particles, and the like.

The toilet system is also provided with a ventilation pipe 6 , an exhaust pipe 8 , a sewage discharge pipe and a water sampling pipe 11 .

The ventilation pipe 6 is connected to the septic tank 3 through the microbial degradation soil layer 4, and its air inlet is located outside the microbial degradation soil layer 4 and the toilet 1, and the air outlet is located between the first porous partition layer 13 and the second porous partition. between the plies 14 in order to supply air and/or oxygen sufficiently to the interior of the dirt. The air inlet of the ventilation pipe 6 can be connected to the fan 7 . In order to further improve the supply efficiency of air and/or oxygen, a ventilation branch pipe is provided at the air outlet end of the ventilation pipe 6, so that the ventilation pipe 6 has two or more air outlets, which can ventilate the dirt from different directions.

The exhaust pipe 8 is used to discharge the gas in the septic tank 3 , and it extends from the shell of the septic tank 3 to the outside of the microbial degradation soil layer 4 , and its air outlet is located outside the microbial degradation soil layer 4 and the toilet 1 . In order to further enhance the deodorizing effect, a deodorizing device (not shown), such as an activated carbon deodorizing device, can be connected to the air outlet.

The sewage discharge pipe is arranged on the peripheral wall near the top of the shell of the septic tank 3, and the lower edge of the sewage discharge port 10 is flush with the upper surface of the second porous baffle layer 14 or higher than the second porous baffle plate layer 14. On the upper surface, the sewage in the septic tank 3 is discharged into the microbial degradation soil layer 4 through the sewage discharge port 10 after passing through the second porous separator layer 14. These liquids naturally flow in the microbial degradation soil layer 4, and then enter into the water sampling pipe 11 adjacent to the septic tank 3. The upper and lower ends of the water sampling tube 11 are opened, and the seepage water in the microbial degradation soil layer 4 enters the water sampling tube 11 from the lower opening, and the upper opening is used as a water sampling port. water quality monitoring.

Since the liquid naturally infiltrates from the microbial degradation soil layer 4 into the water sampling tube 11, it may carry solid substances, and these solid substances will affect the detection of water quality. Therefore, a gauze can be arranged at the lower part of the water sampling tube 11 for blocking and filtering out these solid substances in the liquid.
