[0018] See also Figure 1-2 As shown, a high-load infiltration system of the utility model comprises a tank body 1 with an upper opening and a water inlet pipe 2, wherein the tank body 1 is provided with multiple layers of fillers 3; an air inlet pipe 4 connected to an external wind source is provided in the tank body 1, and each layer of the multiple layers of fillers 3 is provided with a horizontal air distribution pipe 5 connected to the air inlet pipe 4; a siphon water outlet component 6 is provided in the tank body 1, and the water inlet end of the siphon water outlet component 6 is located at the bottom layer of the multiple layers of fillers 3. A sealing structure is provided at the bottom of the tank body, and its specific structure is a prior art and is common knowledge to those skilled in the art, and will not be described in detail here.

[0019] An openable inspection cover is provided at the opening end of the tank body, and a vent is provided on the inspection cover. The inspection cover is usually in a sealed state, and activated carbon is provided in the vent for filtering, which can reduce the escape of sewage odor.

[0020] Air is transported to the multi-layer filler through the air intake pipe and the horizontal air distribution pipe connected to the external wind source to supplement oxygen, so that there is enough oxygen in the multi-layer filler to degrade organic matter, effectively improving the sewage treatment efficiency.

[0021] The use of siphon discharge can prolong the hydraulic retention time of domestic sewage in the system, and can better complete denitrification in an oxygen-deficient environment to achieve the effect of nitrogen removal. In addition, due to the pressure difference between the inside and outside of the system during water discharge, the external air can be brought into the system during the process of the liquid level dropping in the system during water discharge, realizing a reciprocating aerobic and anoxic environment in the system, so that the system can better undergo nitrification and denitrification reactions and achieve the effect of nitrogen removal.

[0022] The siphon water outlet component is connected to an external ecological pond, in which bottom mud is laid and submerged plants and emergent plants are planted. The nitrogen and phosphorus substances contained in the water coming out of the system are required for plant growth.

[0023] In this embodiment, preferably, the multi-layer filler 3 includes a primary filter layer 3a composed of bamboo charcoal, loam, and natural inert organic materials, a filter layer 3b composed of coarse gravel ceramsite medical stone is provided below the primary filter layer 3a, a deep filter layer 3c composed of peat, fine sand, loam, and natural inert organic materials is provided below the filter layer 3b, and a water outlet layer 3d composed of coarse gravel and slag is provided at the bottom. After the above-mentioned components are configured, the bamboo charcoal in the primary filter layer has a loose and porous structure, has a strong adsorption capacity, can purify the air, and eliminate odors. Loam contains large and small particles, moderate voids, air, moderate drainage and water retention, contains a lot of air in the pores, can attach a large amount of water, and stores nutrients. Microorganisms rely on organic matter in loam to survive and reproduce. Natural inert organic materials can be converted into organic matter and fast-acting nutrients through decomposition, which not only improves the physical and chemical properties of the soil, but also supplies certain nutrients. At the same time, its loose porous structure can effectively retain moisture, reduce the sewage infiltration rate, prolong the hydraulic retention time, and provide a good place for the growth and reproduction of microorganisms.

[0024] The outer shell of the ceramsite in the filter layer is ceramic or enamel, which has the function of water isolation and air retention. The internal structure of the ceramsite is characterized by fine honeycomb micropores, which can better reoxygenate the sewage. Medical stone can absorb free metal ions in water and has the function of adjusting pH.

[0025] The peat in the deep filter layer is loose and porous, which enables it to absorb and retain a large amount of water, improve the soil's ability to hold water, ventilate and retain fertilizer, and increase the nutritional content.

[0026] The effluent layer is composed of coarse gravel and slag, both of which have rough surface areas, which can increase the contact area of ​​sewage and prolong the infiltration time. In addition, the gaps between the two gravels at the bottom are large, which can better reoxygenate the sewage.

[0027] In this embodiment, preferably, the free end of the horizontal air distribution pipe 5 in the deep filter layer 3c is provided with an aeration pipe 7 connected to the outside for aeration and adding a carbon source. By providing an aeration pipe, a carbon source is added to the deep filter layer separately, the denitrification efficiency of the deep filter layer is improved, and the effluent quality is improved.

[0028] Preferably, a Niemi trough 8 is detachably provided above the multi-layer filler 3; a fine sand filler 9 is provided in the Niemi trough 8, and the outlet end of the water inlet pipe 2 is located at the lower end of the Niemi trough 8. A handle is provided on the Niemi trough for easy carrying, and when the water in the Niemi trough is full, the water overflows to evenly distribute the water. The sewage is pre-treated by the Niemi trough, and the use of 5-10mm fine sand filler can effectively filter various suspended matter in domestic sewage, reduce the clogging caused by suspended matter entering the filter material, and can extend the service life of the bottom filter layer, reduce the cleaning and replacement of the filter material, and only need to clean or replace the Niemi trough.

[0029] Further preferably, a plurality of water distribution holes 10 are evenly distributed along the circumferential direction on the side wall near the upper end of the Niemi trough 8, and the water distribution holes 10 are located above the fine sand filler 9. By arranging the water distribution holes on the side wall of the upper end of the Niemi trough, the suspended matter on the water surface is reduced from overflowing from the Niemi trough with water into the multi-layer filler below.

[0030] In this embodiment, the side wall of the tank body 1 is provided with inspection holes 11 corresponding to each layer of the multi-layer filler 3, and each inspection hole 11 is connected to a ball valve and an inspection pipeline. When the system is blocked, the system is filled with clean water. After the clean water has penetrated completely, the ball valve is opened step by step, and it can be checked whether a layer is blocked, so as to facilitate cleaning and replacement.

[0031] In this embodiment, preferably, a plurality of reinforcing hoops 12 are vertically spaced apart on the outer wall of the tank body 1. The reinforcing hoops are provided to prevent the equipment from being damaged by excessive internal pressure when water is introduced into the equipment after the equipment is filled with stuffing.

[0032] In this embodiment, the siphon water outlet assembly 6 includes a vertical water pipe 6a, an S-shaped siphon pipe 6b is connected to the upper end of the vertical water pipe 6a, and a solenoid valve 6c is provided on the siphon pipe 6b. The siphon pipe is equipped with a solenoid valve, which is linked to the water level inside the system. When the liquid level reaches a certain position, the solenoid valve opens, and the siphon pipe generates a siphon due to the pressure difference between the inside and outside, and the sewage that has been filtered inside the system is discharged. According to the actual setting height of the siphon pipe, when the outlet water has a sufficient height difference to form a natural siphon, the solenoid valve may not be installed.

[0033] During operation, domestic sewage is input into the Niemi tank through the water inlet pipe, and most of the floating objects are initially filtered out through fine sand filler. When the water level in the Niemi tank reaches a certain height, it overflows onto the multi-layer filler through the water distribution holes. The domestic sewage is filtered through the primary filtration layer, the filtration layer, and the deep filtration layer in turn and then enters the outlet layer. When the water level in the tank reaches a predetermined height, the solenoid valve opens and discharges the water at the outlet layer through the siphon to the external ecological pond.
