Background

Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people.

The village and town sewage mainly comprises domestic sewage and agricultural wastewater. The domestic sewage has fixed components, mainly contains organic matters such as carbohydrate, protein, amino acid, fat and the like, is more suitable for the growth of bacteria, and becomes a place for the survival and propagation of bacteria and viruses; but the domestic sewage generally does not contain toxicity, has certain fertilizer efficiency and can be used for irrigating farmlands. The agricultural wastewater has various components, and different treatment methods are needed for wastewater in villages and towns with different development targets in different seasons, different places and different development targets. In order to reduce the discharge amount and complexity of sewage during sewage treatment, the construction of methane tanks which are being popularized vigorously by China is combined to separate toilet flushing water (black water) from other domestic water (grey water). The grey water is treated by a natural purification system, and the black water and human and animal excreta are treated by an anaerobic methane tank, so that the discharge amount, complexity and treatment cost of sewage can be reduced, and the method has important significance for developing clean new energy in rural areas, protecting human living environment, promoting sustainable development of rural economic society and the like.

In order to facilitate further understanding of the above technical solutions, the structural working principle is now explained:

as shown in figure 1, the rural sewage treatment system carries out deep harmless treatment on rural sewage, can be used as an organic fertilizer through first three-grid primary treatment, and can also be used as an organic fertilizer through five-grid deep treatment, so that the sewage reaches the standard and is discharged, and the environmental protection requirement is met; the whole system mainly comprises five pools: a primary anaerobic tank 21, a secondary anaerobic tank 19, an aerobic tank 17, a deep filtering tank 22 and a reclaimed water storage tank 23.

In the sewage treatment principle, the first step is harmless pretreatment, and the system is equipment for treating excrement condensate and filtering and precipitating the excrement condensate; a small-sized treatment structure for cellular precipitation of domestic sewage and anaerobic digestion of sludge; carrying out filtration, precipitation and fermentation harmless treatment on the condensate in the sewage containing the condensate through a three-grid septic tank; the principle is that the condensate is decomposed at the bottom of the pool, and the sewage on the upper layer flows away through a flow guide pipe; when the sewage flows into the aerobic tank 17, the condensate basically does not exist; the material water in the aerobic tank 17 exists in a liquid state basically. The second step is sewage deep treatment, liquid sewage in the aerobic tank 17 is guided into a deep filtering tank 22 through a diversion pipe III 16, and the deep filtering tank 22 is composed of five layers of filtering cores. After being filtered by the five-layer filter element and comprehensively treated by adding the chemicals through the second chemical feeding port 7, the sewage is discharged after reaching the standard.

The working process of the sewage system is that sewage and condensate flow into the first-stage anaerobic tank 21 through the sewage inlet 1 for sedimentation, decomposition and fermentation, and after the tank is fully piled up, supernatant flows into the second-stage anaerobic tank 19 through the first diversion pipe 20 for continuous anaerobic fermentation and decomposition and fermentation; after the secondary anaerobic fermentation, the condensate is precipitated, only clear supernatant is left on the upper layer, the supernatant flows into a third grid aerobic tank 17 through a second diversion pipe 18 for aerobic and clarification treatment, and the aerobic tank 17 is aerated through an aeration pipe 3, so that oxygen in sewage is increased, microorganisms in the sewage are proliferated, organic matters are further degraded, and the water quality is clearer; the water in the third aerobic tank 17 is guided into the deep filtering tank 22 through the third flow guide pipe 16, the first-stage filtering core 15, the second-stage filtering core 14, the third-stage filtering core 13 and the fourth-stage filtering core 12 are sequentially arranged in the deep filtering tank 22 from top to bottom, the sewage flows into the reclaimed water storage tank 23 after being filtered by the filtering cores, the water in the reclaimed water storage tank 23 is subjected to chemical feeding through the second chemical feeding port 7 to comprehensively treat the water in the reclaimed water storage tank 23, and then is pumped out through the water pump 10 to be utilized or is naturally discharged through the fourth flow guide pipe 11; in the process, if the reclaimed water storage tank 23 collects and detects water through the detection collection port and does not reach the standard, the water is directly discharged through the water pump 10, then discharged through the reclaimed water retreatment inlet 5 above the deep filter tank 22, sewage is treated in a deep layer again, and the sewage is discharged after reaching the standard.

In general, domestic sewage enters a first-stage anaerobic tank 21 and a second-stage anaerobic tank 19 for anaerobic decomposition and precipitation, and solid sewage is subjected to anaerobic digestion and precipitation; performing innocent treatment, wherein the supernatant of the primary anaerobic tank 21 and the secondary anaerobic tank 19 flows into the aerobic tank 17, if the supernatant is used as an organic fertilizer, the supernatant is directly clarified and can be pumped out for direct use, and if the supernatant is not used as an organic fertilizer, the supernatant is subjected to dosing and aeration treatment to perform primary deep treatment on the sewage; after the aerobic tank 17 carries out primary deep-layer treatment on sewage, the sewage is discharged into a deep-layer filtering tank 22 to carry out secondary deep-layer (quintuple filtering) treatment, the sewage is discharged into a reclaimed water storage tank 23 after the treatment is finished, the sewage enters the reclaimed water storage tank 23, and the sewage can be directly discharged or recycled after the detection that the sewage reaches the standard; if the reclaimed water in the reclaimed water storage tank 23 does not reach the standard after detection, the reclaimed water can be directly discharged into the deep filter tank 22 through the water pump 10 for retreatment or subjected to chemical adding treatment until the detection reaches the standard.

In the description of the present invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
