Description

Four-grid septic tank for rural toilet fecal sewage treatment

Technical Field

The utility model belongs to the environmental protection field relates to a four-grid septic tank of rural lavatory excrement and sewage treatment.

Background

The national rural toilet revolution mainly pushes the three-format septic tank technology. By the end of 2020, more than 65% of rural areas in China complete the toilet change task of farmers, and the toilet environment of farmers is obviously improved by using harmless sanitary toilets. But the three-format septic tanks popularized and used in China have simple structure, single function and lower treatment efficiency, and can not well meet the requirement of rural toilet sewage treatment. In addition, the three-grid septic tank has strict requirements on the flushing water quantity of the toilet in use, the flushing water quantity cannot exceed 2 liters every time, and the rural miscellaneous drainage of peasant households such as washing clothes, bathing, washing, kitchen and the like is limited to be drained, so that inconvenience is brought to the peasant households. Therefore, further improvements to existing septic tanks are needed.

Disclosure of Invention

The utility model aims at providing a four format septic tanks of rural lavatory excrement and sewage processing overcomes three format septic tanks simple structure, function singleness, efficiency are not high, use the high problem of constraint condition that use of present rural lavatory revolution popularization and use.

The utility model discloses a following technical scheme realizes: the utility model provides a four format septic tanks of rural lavatory excrement and sewage treatment, includes the septic tank, the septic tank divide into four check, four check septic tank lateral walls all communicate through the pipeline, first check septic tank passes through pipe connection bath closestool, the anaerobism bioreactor is equipped with in the second check septic tank, the aerobic bioreactor is equipped with in the third check septic tank, aeration equipment is connected to the third check septic tank, aeration equipment's aeration pipe stretches into the bottom and the aeration dish of third check septic tank and is connected, be covered with the aperture on the aeration dish, fourth check septic tank is connected with irrigation system.

Furthermore, the first septic tank is connected with an exhaust pipe.

Furthermore, a rain-proof cap is arranged at the top of the exhaust pipe.

Furthermore, a liquid level sensor is arranged at the upper part of the fourth-grid septic tank.

Furthermore, the first septic tank, the second septic tank, the third septic tank and the fourth septic tank are all provided with openings, and the openings are all provided with sealing covers.

Adopt above-mentioned technical scheme's positive effect: the septic tank is divided into four lattices, each lattice performs different functions, the manure can be fully decomposed, and tail water generated in the whole process can be discharged in time; the utility model discloses solve the difficult problem of rural lavatory excrement and sewage processing to the rural lavatory revolution of china and have very important effect, can effectively compensate the problem that the rural lavatory revolution of china technical equipment short slab, be fit for vast rural improvement of village lavatory large tracts of land and popularize and apply.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1 a first septic tank, 2 a second septic tank, 3 a third septic tank, 4 a fourth septic tank, 5 a flushing closestool, 6 an anaerobic bioreactor, 7 an aerobic bioreactor, 8 an aeration device, 9 an aeration disc, 10 an aeration pipe, 11 an irrigation system, 12 an exhaust pipe, 13 a rain hat and 14 a liquid level sensor.

Detailed Description

The technical solution of the present invention is further described below with reference to the accompanying drawings, but should not be construed as limiting the present invention:

fig. 1 is a schematic structural diagram of the utility model, and as shown in the figure, a four-grid septic tank for rural toilet sewage treatment comprises a septic tank. The septic tank is divided into four lattices, the side walls of the four-lattice septic tank are communicated through pipelines, the first-lattice septic tank 1 is connected with a flushing closestool 5 through a pipeline, an anaerobic bioreactor 6 is arranged in the second-lattice septic tank 2, the anaerobic bioreactor is mainly filled with anaerobic fermentation strains and adhesion media thereof, and anaerobic fermentation is carried out in the second-lattice septic tank; an aerobic bioreactor 7 is arranged in the third septic tank 3, and the aerobic bioreactor is mainly filled with aerobic fermentation strains and adhesion media thereof. The anaerobic bioreactor and the aerobic bioreactor have the same medium effect, and are used for improving the specific surface area, increasing the attachment surface of microorganisms and further improving the fermentation efficiency. The aeration device 8 is connected to third grid septic tank 3, and the aeration pipe 9 of aeration device 8 stretches into the bottom and the aeration dish 10 of third grid septic tank and is connected, is covered with the aperture on the aeration dish 10, provides oxygen, makes things convenient for aerobic fermentation to third grid septic tank 3 by aeration device. The fourth septic tank 4 is connected with an irrigation system 11, and finally produced tail water is discharged through the irrigation system for agricultural irrigation.

In order to discharge the gas of the septic tank in time, the first septic tank 1 is also connected with an exhaust pipe 12.

The top of the exhaust pipe 12 is provided with a rain cap 13, which can prevent rainwater from dripping into the exhaust pipe.

In order to sense the liquid level of the fourth-grid septic tank in time, a liquid level sensor 14 is arranged at the upper part of the fourth-grid septic tank 4. When the liquid level is set to be high, the irrigation system is started, and tail water in the fourth grid is discharged.

First check septic tank 1, second check septic tank 2, third check septic tank 3, fourth check septic tank 4 on all be equipped with clearly draw the mouth, clearly draw the mouth and all be equipped with sealed lid, conveniently open the clear excrement sediment of drawing the septic tank.

During the use, the excrement is dirty through bath toilet, then gets into first check manure pit through the pipeline, carries out the fermentation decomposition, then gets into second check manure pit and carries out anaerobic fermentation, and the reentrant third check manure pit carries out good oxygen fermentation, and the further fermentation of entering fourth check manure pit at last and storage, when fourth check manure pit liquid level reached and set for the height, by the liquid level inductor perception after, start irrigation system in time the tail water of discharging.

The septic tank is divided into four lattices, each lattice performs different functions, the manure can be fully decomposed, and tail water generated in the whole process can be discharged in time; the utility model discloses solve the difficult problem of rural lavatory excrement and sewage processing to the rural lavatory revolution of china and have very important effect, can effectively compensate the problem that the rural lavatory revolution of china technical equipment short slab, be fit for vast rural improvement of village lavatory large tracts of land and popularize and apply.
