AI Technical Summary
In mountainous areas or where sewage pumps are very high, the septic tank outlet is difficult to be higher than the main municipal pipe network or sewage access point, resulting in inconvenience in sewage discharge; when the septic tank's water treatment volume suddenly increases, sludge is likely to flow into the main municipal pipeline along with the sewage, causing an increase in sedimentation.
The septic tank adopts a three-chamber structure, including a primary sedimentation and fermentation tank, a secondary filtration tank, and a tertiary clarification tank. The collection well is equipped with a sewage lift pump and double-layer shock absorbers. The sewage lift pump provides pressure to lift sewage. The collection well is equipped with water passage holes and an electronic liquid level controller. The arrangement of the water passage holes is optimized to stabilize the liquid level and reduce the disturbance of sludge sediment. An independent collection well is set up. The disturbance of the lower layer by the sewage flow achieves the stability of the supernatant. The flow of sewage reduces the fluctuation of the liquid level in the septic tank and indirectly reduces the impact of sediment.
It enables effective wastewater discharge in complex terrain, reduces sludge entering municipal pipelines, lowers sludge sedimentation levels, and improves the stability and efficiency of wastewater treatment.

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0042] Referring to Figures 1 to 5 The present application is a septic sewage lifting integrated structure, which comprises a three format septic tank 1. The three format septic tank 1 comprises a first stage sedimentation and fermentation tank 1.1, a second stage filter tank 1.2 and a third stage clarifier 1.3 arranged in sequence from the water inlet to the water outlet.
[0043] A water collecting well 2 is arranged in the second stage filter tank 1.2 or the third stage clarifier 1.3.
[0044] When the water collecting well 2 is arranged in the third stage clarifier 1.3, the water collecting well 2 is an open structure surrounded by the right pool wall of the third stage clarifier 1.3. The water collecting well 2 comprises a front wall, a rear wall, a left wall, the right pool wall of the third stage clarifier 1.3 and a bottom wall. The bottom wall is connected to the middle part of the right pool wall of the third stage clarifier 1.3. The top of the well wall of the water collecting well 2 is higher than the normal water level of the third stage clarifier 1.3.
[0045] The left wall of the water collecting well 2 is provided with a water hole 3. The water hole 3 is provided with at least one row.
[0046] A sewage lifting pump 4 is arranged in the water collecting well 2 and on the bottom wall. The bottom of the sewage lifting pump 4 is provided with a double layer damping piece 5. The double layer damping piece 5 comprises a pair of rubber pads and a steel plate arranged between the pair of rubber pads. The thickness of the rubber pad is 20 mm, and the thickness of the steel plate is 10 mm.
[0047] An electronic liquid level controller 6 is arranged in the water collecting well 2.
[0048] When the water collecting well 2 is arranged in the second stage filter tank 1.2, the arrangement structure of the water collecting well 2 is the same as that when the water collecting well 2 is arranged in the third stage clarifier 1.3.
[0049] When there is no obvious peak period of sewage discharge throughout the day or during the day, i.e., the amount of drainage is relatively uniform throughout the day or during the day, the water passing holes 3 adopt a one-dimensional arrangement.
[0050] When there is an obvious peak period of sewage discharge throughout the day or during the day, i.e., the drainage peak period is obvious and the peak period is mainly after getting up in the morning, during class, and before going to bed at night, the water passing holes 3 adopt a multi-row and multi-column arrangement.
[0051] Specifically, the arrangement of the water passing holes:
[0052] The arrangement of the water passing holes mainly involves the influence on the water level of the three-format septic tank. The flow of the water passing holes is not the same as the water inflow of the three-format septic tank, so whether the water inflow has obvious fluctuations leads to the frequency of the liquid level fluctuation in the septic tank in a short time.
[0053] The greater the frequency, the greater the influence on the turbidity of the supernatant (not considering the fluctuation amplitude, because the liquid level fluctuation frequency in the entire three-format septic tank is very small, the liquid level amplitude in the supernatant range is difficult to affect the turbidity).
[0054] In order to eliminate the influence of the precipitate on the supernatant caused by the water level fluctuation of the three-format septic tank, the water passing holes are arranged to reduce the back-and-forth fluctuation of the liquid level in the septic tank, thereby indirectly reducing the influence of the precipitate on the supernatant.
[0055] In example one, when there is no obvious peak period of sewage discharge throughout the day or during the day (such as train stations, terminal buildings, shopping malls, public toilets in parks, etc.), the amount of drainage is relatively uniform throughout the day or during the day.
[0056] The water passing holes can adopt a one-dimensional arrangement.
[0057] The water flow is stable during the drainage period, the liquid level in the septic tank is stable, the water passing holes are arranged in a one-dimensional manner, so that the liquid level remains stable and avoids the back-and-forth fluctuation of the liquid level.
[0058] In example two, when there is an obvious peak period of sewage discharge throughout the day or during the day (such as schools, residential buildings, etc.), the drainage peak period is obvious and the peak period is mainly after getting up in the morning, during class, and before going to bed at night.
[0059] The water passing holes can adopt a multi-row and multi-column arrangement.
[0060] In this way, more supernatant can be discharged during the low period, the liquid level in the septic tank is reduced, the water inflow is increased during the peak period, the liquid level in the septic tank is supplemented, the frequency of the liquid level fluctuation in the septic tank is reduced, and the influence on the supernatant is reduced.
[0061] Reference Figure 4As shown, when the sewage lifting pump 4 is a mobile sewage lifting pump, the double-layer damping member 5 is arranged on the base of the mobile sewage lifting pump.
[0062] Referring to Figure 5 As shown, when the sewage lifting pump 4 is a coupled sewage lifting pump, the double-layer damping member 5 is arranged on the floor-mounted elbow foot of the coupled sewage lifting pump.
[0063] The first partition wall is provided with a first water passing opening 9 in the middle part;
[0064] The second partition wall is provided with a second water passing opening 10 in the middle part;
[0065] The first sedimentation and fermentation tank 1.1, the second filtration tank 1.2 and the third clarification tank 1.3 are all provided with a reserved hole 7 in the middle part, and a horizontal air pipe 8 is arranged in the reserved hole 7, and the diameter of the air pipe 8 is 150 mm.
[0066] The electronic liquid level controller 6 comprises a probe 6.1 and a control panel 6.2, the probe 6.1 is arranged in the collecting well 2, the control panel 6.2 and the probe 6.1 are electrically connected through a control line 6.3, and the control panel 6.2 and the sewage lifting pump 4 are electrically connected through a power line 6.4.
[0067] The present application solves the vibration generated when the sewage lifting pump operates or the interference of the sewage flow to the lower sludge, realizes the removal of the supernatant, avoids the lower sludge into the pressure drainage system into the large municipal or sewage canal, the present application adopts the sewage lifting mode, discharges the sewage into the large municipal or sewage canal with high water level, integrates the sewage lifting pump and the three-format septic tank, reduces the construction quantity of the sewage discharge building, and the present application can realize the factory prefabrication.
[0068] The effective volume of the collecting well 2 in which the sewage lifting pump 4 is arranged, that is, the drainage volume of the sewage lifting pump 4 each time when starting:
[0069] V 有效 = Q 泵 ·t;
[0070] V 总 = V 有效 ·(1.3~1.5) 1.3~1.5 coefficient, mainly considering the height of the sewage pump suction port and the safety water level when the water pump stops;
[0071] V 总 The actual total volume of the collecting well (according to the value, the length, width and height of the collecting well can be determined);
[0072] V 有效Effective volume, m3 (water pump discharge per start);
[0073] Q 泵 Sewage pump flow, m3 / h;
[0074] t - sewage pump each time the running time, h (according to the use of water pump, life, etc. Set)
[0075] The working process of the integrated structure of the septic tank sewage lifting:
[0076] When the discharge port position of the three-format septic tank 1 is higher than the access point of the municipal pipe network or sewage canal, an independent water collecting well 2 is arranged in the secondary filter tank 1.2 or the tertiary clarifier 1.3. The following is an example of the water collecting well 2 arranged in the tertiary clarifier 1.3:
[0077] 1, determine the arrangement of the water passing hole 3 on the water collecting well 2;
[0078] The arrangement of the water passing hole mainly involves the influence on the water level of the three-format septic tank. The flow of the water passing hole is not the same as the water inflow of the three-format septic tank, so whether the water inflow is obviously floating or not will cause the floating frequency of the liquid level in the septic tank in a short time.
[0079] The greater the frequency, the greater the influence on the turbidity of the supernatant (not considering the floating amplitude, because the liquid level amplitude in the supernatant range is difficult to affect the turbidity due to the very small floating frequency of the liquid level in the entire three-format septic tank).
[0080] In order to eliminate the influence of the precipitate on the supernatant caused by the water level floating of the three-format septic tank, the arrangement of the water passing hole is used to reduce the back and forth floating of the liquid level in the septic tank, thereby indirectly reducing the influence of the precipitate on the supernatant.
[0081] Example one, all day or daytime, when there is no obvious peak period of sewage discharge (such as train station, terminal, shopping mall, public toilet in park, etc.), the water discharge is relatively uniform all day or during the daytime.
[0082] The water passing hole can adopt a one-dimensional arrangement.
[0083] The water flow is stable during the drainage period, and the liquid level in the septic tank is stable. The one-dimensional arrangement of the water passing hole makes the liquid level always stable, avoiding the back and forth floating of the liquid level.
[0084] Example two, all day or daytime, when there is an obvious peak period of sewage discharge (such as school, residential building, etc.), the peak period of water discharge is obvious and mainly after getting up in the morning, during the class, and before going to bed at night.
[0085] The water passing hole can adopt a multi-row and multi-column arrangement.
[0086] This kind of mode, can in the low period, more supernatant is excluded, reduce the liquid level in the septic tank, the peak period of water increase, make up the liquid level in the septic tank, reduce the liquid level in the septic tank up and down floating times, reduce its influence on supernatant.
[0087] 2, sewage three format septic tank 1 in the flow process:
[0088] Sewage from the side wall of the first stage of sedimentation fermentation tank 1.1 upper flow into the first stage of sedimentation fermentation tank 1.1, and then through the first water opening 9 in the middle of the first partition wall to the second stage of filter tank 1.2, and then through the second water opening 10 in the middle of the second partition wall to the third stage of clarification tank 1.3.
[0089] The water level in the first stage of sedimentation fermentation tank 1.1, the second stage of filter tank 1.2 and the third stage of clarification tank 1.3 is level.
[0090] 3, the starting and stopping point of sewage lifting pump 4 in the water collecting well 2:
[0091] The sewage in the third stage of clarification tank 1.3 flows to the water collecting well 2 through the water hole 3 on the left wall of the water collecting well 2.
[0092] When the water level in the water collecting well 2 is level with the highest point of the water hole 3, it is the starting water level of the sewage lifting pump 4, at this time, the sewage lifting pump 4 is started by the electronic liquid level controller 6.
[0093] When the water level in the water collecting well 2 drops to the middle of the sewage lifting pump 4, it is the stopping water level of the sewage lifting pump 4, at this time, the sewage lifting pump 4 is stopped by the electronic liquid level controller 6.
