Description

Technical Field

[0001] The present invention relates to the field of feces treatment, and particularly to a centralized treatment system for harmless and resourceful treatment of rural toilet renovation fecal sewage. Background Art

[0002] The harmless and resourceful treatment of feces refers to the treatment measures that can effectively reduce the number of biological pathogenic factors in human feces and make the pathogens lose their infectivity. If the feces of rural toilets are not treated harmlessly, they will stink, attract flies, breed maggots, pollute the environment and water bodies, and may cause infectious diseases, seriously endangering the physical health of the surrounding population. To solve this problem, a transportation tool (fecal suction truck) can be used to transfer it to a special feces and urine treatment station for harmless treatment. The fecal residue after harmless treatment is a very good organic fertilizer. Using organic fertilizer can improve the quality of agricultural products, increase economic benefits, realize resource recycling, and can also effectively remove and kill the pathogens in feces, meeting the harmless sanitation requirements of feces and causing no pollution to the environment.

[0003] The existing fecal sewage harmless treatment system of special feces and urine treatment stations generally adopts multiple tanks and multiple pumps with single-tank circulation. This arrangement is only suitable for small-scale fecal stations, is not convenient for treating a large amount of feces, requires too much equipment, has a high cost, and brings great inconvenience to the construction planning of sewage treatment plants. And when multiple tanks are connected, how to more conveniently control and realize the fecal sewage circulation between multiple tanks is an important problem faced; at the same time, the brick-built wells and down-pipe wells in the existing technology are prone to leakage, and the leakage pollutes the soil and groundwater.

[0032] Embodiment 1

[0033] As Figure 1 shown, in the present invention, the septic separation tank 1 and the septic tank 2 can be arranged in a straight line.

[0034] The layout of the present invention does not necessarily have to be arranged in a straight line, and can be modified according to the on-site geographical location during construction and planning.

[0035] Embodiment 2

[0036] As Figure 5 shown, the septic tanks 2 can be arranged in two rows according to geographical restrictions. The connection and control methods between each septic tank 2 and the septic separation tank 1 are the same as those in Embodiment 1.

[0037] As Figures 1 to 5 shown, the present invention can include 2 septic separation tanks 1, which are respectively labeled as Tank No. 1 and Tank No. 2, and also include 16 septic tanks 2, which are respectively labeled as Tanks No. 3 - 18.

[0038] Through the above layout, the rural toilet renovation fecal sewage harmless and resource centralized treatment system can achieve the following functions:

[0039] (1) Fecal liquid separation: Open the valve of the high pipe A101 of the septic separation tank 1, close the other valves of the system, pour the feces transported by the cleaning tool into the low well 5, and use the submersible pump 8 in the low well 5 to pump it into the high connecting pipe 4. The feces flow into the septic separation tank 1 from the high pipe A101 and stand for 24H. Under the action of gravity, solid-liquid separation occurs. When the valve of the low pipe A102 is opened, the liquid flows away. When the valves of other pipes are closed and the valve of the lower pipe 103 is opened, the viscous feces flow into the low well 5 through the lower connecting pipe 9. Use the submersible pump 8 to suck the viscous feces into the open pipe 6. The quick connector 7 connected to the open pipe 6 can be connected to the cleaning tool, and the viscous feces are pumped into the cleaning tool and then transported to other treatment stations for secondary treatment;

[0040] (2) Single tank circulation: Taking the 18th tank of the septic tank 2 as an example, when the high pipe B201 and the low pipe B202 of the 18th tank are opened and the valves of the other tanks are closed, the fecal sewage in the 18th tank sequentially passes through the low pipe B202, the low connecting pipe 3 into the low well 5, and is then pumped by the submersible pump 8 in the low well 5, enters the high connecting pipe 4 through the open pipe 6, and then flows into the 18th tank through the high pipe B201 of the 18th tank to complete the single tank circulation; The single tank circulation principles of the other septic tanks 2 and the septic separation tanks 1 are the same; Single tank circulation can be applied when microorganisms need to be added to a single tank for fermentation, and uniform fermentation is achieved through circulation;

[0041] (3) Transfer between any two tanks: Taking the 18th tank of the septic tank 2 and the 1st tank of the septic separation tank 1 as an example, when the high pipe B201 of the 18th tank and the low pipe A102 of the 1st tank are opened and the other valves are closed, the fecal liquid in the 1st tank can be pumped into the 18th tank sequentially through the low connecting pipe 3, the low well 5, the open pipe 6 and the high connecting pipe 4 to complete the liquid transfer between the tanks;

[0042] (4) Extraction of the fermented feces in any tank: Taking the 18th tank of the septic tank 2 as an example, when the feces in the tank are completely fermented, it is necessary to extract the fermented feces in the tank. Open the valve of the low pipe B202 of the 18th tank, close the valves of the other tanks and the high pipe B201 of the 18th tank. The feces in the 18th tank flow into the low well 5. Connect one end of the open pipe 6 with the quick connector 7 to the cleaning tool, and use the submersible pump 8 to pump the fecal sewage in the low well 5 into the cleaning tool for convenient reuse of the feces.

[0043] In the above working principle, the present invention realizes the connection of the same ends of each tank body, and then uses the low well 5 to connect the high connecting pipe 4, so as to realize the setting of only one submersible pump 8, which can complete multiple functions such as single-tank circulation, transfer between any two tank bodies, and extraction of feces in any tank body, improving the problem of inconvenient control among multiple tanks in the prior art; at the same time, by setting the septic separation tank 1, the function of fecal liquid separation is completed by a single tank body, avoiding the complicated processes and consumption of various devices in the prior art; moreover, the present invention also connects the open pipe 6 with a quick connector 7, which can directly extract the fecal liquid in the low well 5 into the cleaning tool, and can quickly extract the fecal liquid in each tank body in the system for reuse; and by setting the low well 5 as a bottomed cylindrical structure, the problem of easy leakage of brick-built water wells and down-pipe water wells in the prior art is improved, reducing the adverse impact on the ecological environment; the structure of the present invention is simple, with rich functions, convenient for adjusting and switching multiple functions, and has little impact on the surrounding environment, and is suitable as an alternative product to the existing rural toilet renovation fecal water harmless and resource centralized treatment system.
