Background
The toilet revolution is an important measure for improving the rural human settlements. However, the current policy is only to change the water closet to the dry toilet, each household builds a three-format septic tank, and no solution is provided for how to know the full septic tank and how to treat sewage in the follow-up process, and the matching fund is further lacked.
According to statistics, in 2018, about less than 30% of rural areas in China have been built with sewage treatment facilities, but the operation status of the built rural sewage treatment facilities is not optimistic, about more than 80% of rural sewage treatment plants in China cannot normally operate according to design load, and at least about 50% of the rural sewage treatment plants are already in the sun. The reason for analyzing the phenomenon is mainly that drainage pipelines are not built in most rural areas in China, and the objective condition of difficulty in collecting sewage exists in the process of treating rural sewage.
The sewage is difficult to collect and is the largest short plate for sewage treatment, and under the condition that the existing sewage pipe network is difficult to build in a large area in rural areas, the adoption of the dung suction truck to pump the sewage is a realistic and feasible scheme. The dung suction vehicle patrols one village like a city watering cart every day, and if a septic tank of a certain household is full and needs to be cleaned, the dung suction vehicle sucks dung for cleaning the septic tank. However, how to know that a certain septic tank is full, the septic tank needs to be opened manually for inspection at regular intervals, which wastes labor and time.
Application publication No. CN 110009877A discloses a septic tank anti-overflow goes out early warning detection device, adopts laser rangefinder module to detect the liquid level. Application publication No. CN 106525203A discloses a novel visual device of septic tank liquid level detection and cell-phone, adopts ultrasonic sensor to detect the liquid level. The sensors in the two detection schemes are required to be installed inside the septic tank, sewage inside the septic tank slowly evaporates for a long time, sensitive devices of the sensors can be polluted, and the sensors cannot normally work, and on the other hand, the sensors are not very beneficial to maintenance and replacement.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 1 is a schematic diagram of one embodiment of the present invention. The septic tank comprises a septic tank manure inlet 1, an air duct 2, small holes 3, an air pressure sensor 4, a solar cell panel 5, an indicator lamp 6, a septic tank water outlet 7, a filtering device 8, a third grid 9 of a three-grid septic tank, a second grid 10 of the three-grid septic tank, a first grid 11 of the three-grid septic tank and a three-grid septic tank 12.
Referring to fig. 1, in a three-compartment septic tank with an air pressure sensor, liquid dung is discharged from a septic tank inlet 1 to a first compartment 11 of a three-compartment septic tank 12, most of the heavy liquid dung is blocked in the first compartment 11 to be fermented, liquid dung flows to a second compartment 10 through a water outlet between the first compartment 11 and the second compartment 10, the fermentation is continued in the second compartment 10, and the liquid dung flows to a third compartment 9 through a water outlet between the second compartment 10 and the third compartment 9. The other components of the three-chamber septic tank 12, except for the air duct 2 and the air pressure sensor 4, are not much different from those of the conventional three-chamber septic tank, and are not described in detail herein for the sake of brevity and are easily understood by those skilled in the art.
Air duct 2 installs in third check 9, and 2 internal diameters of air duct are 5mm, and filter equipment 8 is installed to 2 bottom of air duct, and 2 low ends of air duct are 12mm apart from the 9 bottoms of third check. When no liquid dung exists in the third grid 9, the lower end of the air duct 2 is communicated with the atmosphere, the air pressure in the air duct 2 is one atmosphere, and the air pressure detected by the air pressure sensor 4 connected with the upper end of the air duct 2 is one atmosphere. When the liquid dung in the third grid 9 is increased and the liquid level is higher than the lower end of the air duct 2, the air in the air duct 2 is compressed, the air pressure exceeds one atmosphere, and the air pressure detected by the air pressure sensor 4 connected with the upper end of the air duct 2 is higher than one atmosphere. The air pressure value detected by the air pressure sensor 4 is in direct proportion to the liquid level of the liquid dung in the third chamber 9, and the higher the liquid level is, the larger the air pressure value is. When the liquid level reaches a certain height and sewage needs to be extracted by the dung suction truck, the air pressure sensor 4 gives a signal, the indicator lamp 6 is lightened, and a driver of the dung suction truck who visits daily sees that the lamp is lightened, so that the dung suction truck can be connected with the water outlet 7 of the septic tank to pump the sewage away.
The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best utilize the invention.
