Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, the utility model provides a rural three-grid type septic tank sewage treatment system, which comprises a septic tank 1 and a filter tank 2; three treatment chambers are arranged in the septic tank 1, filling balls 14 are respectively filled in the three treatment chambers, and the three treatment chambers are respectively an anaerobic collection tank 11, an anaerobic fermentation tank 12 and a black ash water collection tank 13; the anaerobic collecting tank 11 is provided with a black ash water discharging pipe 15; the septic tank 1 is connected with the filter tank 2 through a first pipeline 3, and one end of the first pipeline 3 extending into the filter tank 2 extends into the bottom of the filter tank 2; the filter tank 2 is internally filled with a deodorizing filter material 21, an oxyhydrogen removing filter material 22 and a phosphorus removing filter material 23 from bottom to top respectively;
The black ash water enters the septic tank 1 and then sequentially passes through the anaerobic collecting tank 11, the anaerobic fermentation tank 12 and the black ash water collecting tank 13 to enter the filter tank 2. As shown in fig. 1, the anaerobic collecting tank 11, the anaerobic fermentation tank 12 and the black ash water collecting tank 13 are communicated with each other through a communicating pipe 17.
In practice, when the black ash water enters the septic tank 1 through the black ash water discharging pipe 15, the black ash water first flows into the anaerobic collecting tank 11. At this stage, the filler balls 14 act as physical barriers, effectively removing large particle impurities from the black water, creating favorable conditions for subsequent biological treatment. In addition to physical filtration, a specific biological species is also added to the anaerobic collection tank 11. Under anaerobic conditions, the strains can decompose organic matters in black water, such as carbohydrates, proteins and the like, and convert the organic matters into methane and carbon dioxide. This process not only reduces the organic concentration of the black water.
As more black grey water enters, the water level of the anaerobic collection tank 11 gradually rises. When the water level reaches a certain height, water flow naturally enters the anaerobic fermentation tank 12 through the communicating pipe 17. At this stage, the black water is further biologically treated. Anaerobic fermentation is a complex biochemical reaction process in which microorganisms break down more complex organic substances into simple small molecule compounds, which creates conditions for subsequent biogas production.
Next, the treated black water flows into the black gray water collecting tank 13, which is a preliminary tank for temporarily storing and balancing the flow rate and quality of the black water. After that, black water is introduced into the filtering tank 2 through the first pipe 3.
In the filter tank 2, the black water first contacts the deodorizing filter 21. The filter material is usually activated carbon or other high-pore materials, and can adsorb malodorous substances in black water, such as hydrogen sulfide, volatile organic compounds and the like, so as to achieve the deodorizing effect. Next, oxyhydrogen removal filter 22 is provided, which serves to further remove fine suspended matter and partial dissolved matter from the black water, and to improve the transparency and quality of the effluent. Finally, the dephosphorizing filter material 23 adsorbs the phosphorus in the black water to prevent the phosphorus from entering the natural water body to cause water bloom explosion.
Through the above treatment steps, the black water is effectively treated, the effluent not only meets the environmental protection requirement, but also provides a simple and practical sewage treatment scheme for rural areas. In practice, when the black ash water enters the septic tank 1 through the black ash water discharging pipe 15, the black ash water first flows into the anaerobic collecting tank 11. At this stage, the filler balls 14 act as physical barriers, effectively removing large particle impurities from the black water, creating favorable conditions for subsequent biological treatment. In addition to physical filtration, a specific biological species is also added to the anaerobic collection tank 11. Under anaerobic conditions, the strains can decompose organic matters in black water, such as carbohydrates, proteins and the like, and convert the organic matters into methane and carbon dioxide. This process not only reduces the organic concentration of the black water, but also produces biomethane, a gas that can be used as an energy source.
As more black grey water enters, the water level of the anaerobic collection tank 11 gradually rises. When the water level reaches a certain height, water flow naturally enters the anaerobic fermentation tank 12 through the communicating pipe 17. At this stage, the black water is further biologically treated. Anaerobic fermentation is a complex biochemical reaction process in which microorganisms break down more complex organic substances into simple small molecule compounds, which creates conditions for subsequent biogas production.
Next, the treated black water flows into the black gray water collecting tank 13, which is a preliminary tank for temporarily storing and balancing the flow rate and quality of the black water. After that, black water is introduced into the filtering tank 2 through the first pipe 3.
In the filter tank 2, the black water first contacts the deodorizing filter 21. The filter material is usually activated carbon or other high-pore materials, and can adsorb malodorous substances in black water, such as hydrogen sulfide, volatile organic compounds and the like, so as to achieve the deodorizing effect. Next, oxyhydrogen removal filter 22 is provided, which serves to further remove fine suspended matter and partial dissolved matter from the black water, and to improve the transparency and quality of the effluent. Finally, the dephosphorizing filter material 23 adsorbs the phosphorus in the black water to prevent the phosphorus from entering the natural water body to cause water bloom explosion.
Through the above treatment steps, the black water is effectively treated, the effluent not only meets the environmental protection requirement, but also provides a simple and practical sewage treatment scheme for rural areas.
The system combines physical, chemical and biological treatment technologies to comprehensively treat the black water, ensures that the effluent meets the environmental protection requirement, and improves the treatment efficiency and the effluent quality. The system has simple structure, is easy to popularize and apply in rural areas, is simple and convenient to operate and maintain, and reduces the operation difficulty and the operation cost. The deodorizing filter material effectively removes malodorous substances in the black water, and provides better living conditions for rural environments.

Specifically, the black gray water collecting tank 13 is provided with a special gray water discharging pipe 131 above. The ash water discharging pipe 131 is designed into a three-way pipe structure so as to realize multi-source sewage collection. Wherein one end of the greywater drain pipe 131 is directly connected to the kitchen oil separator 132. The oil separation tank 132 has a main function of primarily separating grease from sewage discharged from a kitchen so that the grease floats on the water surface, thereby reducing the interference of the grease on subsequent treatment. The water flow after oil removal treatment continues to enter the black ash water collecting tank 13.
Meanwhile, the other end of the greywater discharge pipe 131 is designed to collect other domestic sewage, such as washing water discharged from a home washing machine, shower water in a bathroom, etc. The impurities, organic matters, chemical cleaning agents and the like contained in the domestic sewage are collected into the black ash water collecting tank 13 through a pipeline for further treatment. Subsequently, the sewage enters the filter tank 2 through the first pipeline 3, where the sewage is subjected to final filtration by using the deodorizing filter 21, the oxyhydrogen filter 22 and the dephosphorizing filter 23. The deodorizing filter 21 effectively adsorbs and removes malodor substances in water; oxyhydrogen filter 22 is capable of eliminating residual chemical cleaners and other harmful substances; the dephosphorizing filter material 23 aims at the common high phosphorus problem in rural areas, and effectively reduces the phosphorus content in sewage in an adsorption mode, thereby preventing further environmental pollution.
Specifically, the filter tank 2 is connected to an inspection well 5 through a second pipe 4. When the sewage is treated in the filter tank 2, the effluent will flow to the manhole 5 through the second pipe 4.
