Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a microorganism cultivation and water distribution system for gray water treatment. Background Art

[0002] Regarding graywater components in rural communities, domestic sewage exhibits the following characteristics: large coefficient of variation in sewage volume, high nitrogen and phosphorus content, strong biodegradability, and low levels of toxic and hazardous substances such as heavy metals, making it suitable for biological treatment technologies. Furthermore, some community sewage discharge points are located far from sewage pipeline networks, which are expensive to construct. Therefore, low-investment, easy-to-maintain sewage treatment processes are preferred for on-site treatment and purification prior to discharge. Given these characteristics, high-efficiency, low-energy consumption, low-cost, and easy-to-maintain sewage treatment technologies are key to addressing current water pollution issues. Propagating microorganisms into domestic sewage can decompose organic components, converting them into inorganic salts for better absorption by agricultural plants. This also prevents direct discharge of organic wastewater into drainage channels, which can lead to bioaccumulation, ensuring effective absorption, decomposition, and conversion of wastewater by biological resources, thus achieving sustainable development standards.

[0003] Because for the reproduction of microorganisms, it is necessary to create a suitable reproduction environment to ensure that the microorganisms can grow and decompose normally. However, in rural community environments, especially in winter environments, the low temperature will lead to low physiological activity of microorganisms, resulting in slow microbial reproduction and slow decomposition efficiency of organic matter. In addition, the soil in winter environments may freeze, so even if the decomposed water is transported to the farmland environment, it will not be able to effectively penetrate into the soil, making it impossible for the plant roots to effectively absorb inorganic salts, and thus unable to achieve rapid water distribution.

[0004] Based on the above problems, it is necessary to set up a microbial cultivation and distribution system for gray water treatment, which can provide a good environment for the normal growth and reproduction of microorganisms, so that microorganisms can effectively decompose the organic matter in the sewage, thereby avoiding the problem of biological enrichment; at the same time, ensure that the treated gray water can be distributed to the farmland environment in a timely and rapid manner, so as to achieve rapid absorption of inorganic salts by plant roots, thereby ensuring the effectiveness of sewage treatment distribution. Utility Model Content

[0005] The purpose of the utility model is to provide a microbial cultivation and distribution system for gray water treatment, which can adapt to the rural community environment in winter, provide a good environment for microorganisms to decompose organic matter in sewage, and at the same time ensure that the treated sewage can be effectively distributed to the farmland environment and absorbed by the plant roots, thereby achieving the effect of effective sewage treatment in rural communities.

[0006] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0007] A microbial cultivation and water distribution system for gray water treatment, comprising a collection tank and a water distribution network;

[0008] Collection tank: equipped with a heating component and connected to the water distribution network;

[0009] Water distribution network: includes water distribution pipes and water distribution pipes. The water distribution pipes are connected to the water outlet of the collection pool, and the water distribution pipes are laid in two layers in the farmland environment. The upper water distribution pipes are connected to the water distribution pipes, and the lower water distribution pipes are connected to the upper water distribution pipes. Seepage ports are arranged at equal intervals on the water distribution pipes, and water seeps out through the seepage ports.

[0010] The collecting pool is provided with a water inlet and a water outlet. The height of the water inlet is lower than that of the water outlet, and the water outlet is connected to the water distribution pipe through a bend structure.

[0011] The height of the water outlet is much higher than the laying position of the water distribution pipe. When the water level in the collection pool exceeds the height of the water outlet, the water flows overflow from the water outlet and flows into the water distribution pipe through the bend structure.

[0012] The water distribution pipe is connected to a second heating component, and the second heating component heats the water flow transported by the water distribution pipe and then transports it to the upper water distribution pipe.

[0013] The water distribution pipeline of the lower layer is provided with a suction pump body, and the end of the water distribution pipeline of the lower layer is connected to the water detection tank.

[0014] Ventilation holes are arranged at equal intervals on the water distribution pipe, and the vent holes are connected to the ventilation pipe. The upper end of the air pipe extends out of the soil surface to connect the inside of the water distribution pipe with the outside air.

[0015] Non-woven fabric layers are laid at the upper and lower positions of the water distribution pipe, and the water distribution pipe is wrapped by the non-woven fabric layers.

[0016] A U-shaped bend is provided at the upper end of the vent pipe, and the opening direction of the U-shaped bend is vertically downward.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] During the setup of this device, the collection tank and water distribution network are set up to achieve microbial cultivation and subsequent water distribution operations. During the setup, a heating component is set up in the collection tank. The set heating component can maintain a certain temperature environment in the collection tank, thereby ensuring that the temperature in the collection tank meets the needs of microbial growth and reproduction, so that the microorganisms in the collection tank decompose organic matter into inorganic salts, thereby ensuring that the sewage can be properly distributed and discharged.

[0019] At the same time, when setting up, water distribution pipes and water distribution pipes are set up. When setting up the water distribution pipes, they are laid in the soil in two layers, upper and lower. For the upper water distribution pipes, it can ensure that the infiltrated soil is absorbed by the plant roots at the first time, while avoiding the freezing problem of the soil around the plant roots, thereby ensuring the effectiveness of water distribution. The lower water distribution pipes set up can return the water from the distribution, so that the water flow that lacks nutrients after the plant roots penetrate and diffuse can be discharged normally into the ditch, realizing the purpose of water circulation; at the same time, under the action of the upper water distribution pipes, it is ensured that the lower water distribution pipes will not freeze, thereby effectively realizing the sewage water distribution circulation operation and allowing inorganic salts to be effectively absorbed by the plant roots.

[0030] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0031] If sewage in rural communities is discharged directly into ditches, the large amount of organic matter it contains will be wasted and will not be able to effectively affect the designated environment and designated area. At the same time, because sewage contains a lot of organic matter, it will cause a large number of plankton to reproduce in the ditches, affecting the normal survival of other organisms in the ditches, and thus causing problems for the normal ecological environment. Discharging these sewage into grasslands after microbial treatment can avoid the problem of nutrient enrichment while making rational use of the organic matter in the sewage, thereby achieving the development requirements of sustainable rural development. At the same time, after being treated and absorbed by plants, the organic matter and inorganic salt content in the sewage are reduced, so when it is discharged into ditches again, the problem of nutrient enrichment will not occur, thus ensuring the effectiveness of sewage treatment. However, it should be taken into consideration that due to the low temperature in rural winter, the microbial life activity will be low, so the organic matter in the collected sewage cannot be decomposed immediately; secondly, due to the low temperature in the winter environment, the water in the soil will freeze. Even if the treated sewage is distributed to the soil, the roots of the plants will not be able to effectively absorb the inorganic salt components, which will greatly extend the water distribution treatment cycle, which is not conducive to the task of farmland sewage treatment.

[0032] Therefore, in order to solve the above problems, a microbial cultivation and water distribution system for gray water treatment is developed, which includes a collection pool 1 and a water distribution network. The collection pool 1 is used to collect and store sewage, and is the main place for microorganisms to decompose organic matter. The water distribution network is laid in the soil, and after the treated sewage in the collection pool 1 is decomposed and treated, the water flow is reasonably distributed to the soil environment through the water distribution network, thereby achieving the purpose of water distribution.

[0033] Collection pool 1:

[0034] A heating component 2 is provided inside, and is connected to the water distribution network; because the collection pool 1 is a place where microorganisms decompose organic matter, that is, the organic matter is decomposed and converted into inorganic salts by microorganisms, so that the plant roots can effectively absorb the inorganic salts. A decrease in temperature will lead to lower life activity of microorganisms or even inactivation, so the heating component 2 is set in the collection pool 1 here. The heating component 2 can ensure that the temperature in the collection pool 1 meets the requirements of normal life activity of microorganisms, so that microorganisms can grow and reproduce normally, and decompose organic matter to produce inorganic salt components to meet the absorption requirements of plant roots. For the heating component that is set, the use of solar panel electric heating can achieve the heating of sewage inside the collection pool, as shown in the attached figure of the specification. Figure 4 and 5 As shown, this is the way in which the hydrothermal pipe is laid in the collection tank, thereby meeting the heating requirements inside the collection tank.

[0035] It should be noted that because it is necessary to adapt to the temperature environment in winter, only the above-mentioned heating component 2 cannot guarantee that the organic matter can be effectively decomposed and digested, so the following structural settings are required:

[0036] Regarding the structural setting of the collection pool 1, the collection pool 1 is provided with a water inlet 7 and a water outlet 5. The height of the water inlet 7 is lower than the height of the water outlet 5, and the water outlet 5 is connected to the water distribution pipe 4 through a bend structure; as shown in the accompanying drawings of the specification Figure 2 As shown, when setting up, the height of the water outlet 5 of the collection tank 1 is positioned higher than the height of the water inlet 7, so that the sewage entering the collection tank 1 can stay in the collection tank 1. Because if the sewage stays for a short time after entering the collection tank 1, and then the sewage is discharged to the outside, some organic matter will not be digested and decomposed. Under normal circumstances, the organic matter that has not been digested and decomposed can continue to be digested and decomposed by microorganisms, and thus converted into inorganic matter to be absorbed by plant roots; and because of the particularity of the winter environment, the life activity of microorganisms will be reduced after leaving the collection tank 1. Therefore, the height of the water outlet 5 is positioned higher than the height of the water inlet 7, so that the sewage entering the collection tank 1 can stay in the collection tank 1 for a certain period of time, so that the microorganisms can decompose and convert most of the organic matter. At the same time, flow control can also be performed here to open the water outlet 5 according to the water consumption demand of the soil to meet the normal growth of soil plants.

[0037] In order to ensure the effective implementation of the water distribution task, the height position of the water outlet 5 is much higher than the laying position of the water distribution pipe 4. When the water surface in the collection pool 1 exceeds the height position of the water outlet 5, the water flows overflow from the water outlet 5 and flows into the water distribution pipe 4 through the curved pipe structure; in order to adapt to the winter environment and realize energy-saving utilization of resources, the height position of the water outlet 5 is higher than the laying position of the water distribution pipe 4, so that under the action of gravity, the water can automatically flow from the water outlet 5 into the water distribution network, and in the state of flowing water, the water will not easily freeze, so that the water can be effectively transported to the water distribution network to achieve the purpose of effective water distribution.

[0038] Water distribution network:

[0039] It includes a water distribution pipe 3 and a water distribution pipe 4. The water distribution pipe 3 is connected to the water outlet 5 of the collection pool 1, and the water distribution pipe 4 is laid in two layers in the farmland environment. The upper water distribution pipe 4 is connected to the water distribution pipe 3, and the lower water distribution pipe 4 is connected to the upper water distribution pipe 4. Water infiltration ports 6 are arranged at equal intervals on the water distribution pipe 4, and water seeps out through the water infiltration ports 6. The water distribution pipe 3 here is used to receive the decomposed water flow and divert it to the water distribution pipe 4. At the same time, the water distribution pipe 4 is laid in the farmland environment so that the water flow entering the water distribution pipe 4 can seep out through the water infiltration ports 6, thereby achieving the purpose of water distribution. The most important thing is that the upper water distribution pipe 4 and the lower water distribution pipe 4 are set here, that is, the water distribution pipe 4 is laid in the soil in two layers, the upper water distribution pipe 4 is used to receive water flow, and serves as the main nutrient diffusion pipe, so that inorganic salts are mainly diffused through the upper water distribution pipe 4 and absorbed by the plant roots. At the same time, the water flow transported is a flowing water flow, which can warm the soil near the plant roots in this state, so that inorganic salts can diffuse more quickly toward the plant roots. At the same time, the lower water distribution pipe 4 is used for water circulation, and the deeper the soil is, the less likely it is to freeze, thereby ensuring that the water flow can circulate normally.

[0040] In order to adapt to the lower winter ambient temperature, the water distribution pipe 4 is connected to a second heating component, and the second heating component heats the water flow transported by the water distribution pipe 4 and then transports it to the upper water distribution pipe 3; the second heating component is set here, and after the second heating component heats the water flow entering the water distribution pipe 4, the diffusion and penetration efficiency of inorganic salts can be further accelerated to avoid freezing problems in the water distribution pipe 4.

[0041] Further set up and optimize the above structure:

[0042] The lower water distribution pipe 4 is provided with a suction pump body 8, and the end of the lower water distribution pipe 4 is connected to the water inspection pool. In order to adapt to the winter environment, a suction pump body 8 is provided at the lower water distribution pipe 4. The suction pump body 8 can accelerate the water circulation rate in the water distribution pipe 4 and make the water flow faster, thereby further avoiding the phenomenon of water freezing in the water distribution pipe 4. At the same time, the circulated water is transported to the water inspection pool to test the content of its internal components. When the water content is determined to be qualified, the water can be discharged into the ditch; if the content of inorganic salts and other components is high, it can be discharged into the collection pool 1 again, and the plant roots can absorb it again and then test it until the discharge requirements are met.

[0043] Air vents 9 are provided at equal intervals on the water distribution pipe 4, and the position of the air vents 9 is matched with a ventilation pipe 10, which extends the upper end of the air pipe out of the soil surface to connect the inside of the water distribution pipe 4 with the outside air. Because of the provision of the second heating component and the suction pump body 8, the water flow in the water distribution pipe 4 will not have the problem of freezing. In order to enable the microorganisms to survive in the water distribution pipe 4 and decompose certain organic matter in the soil, that is, to ensure the normal physiological activity of the microorganisms in the water distribution pipe 4, air vents 9 are provided on the water distribution pipe 4, so that the microorganisms can carry out aerobic activities and decompose the residual organic matter. A U-shaped bend 12 is provided at the upper end of the ventilation pipe, and the opening direction of the U-shaped bend 12 is vertically downward to prevent debris from entering the inside of the water distribution pipe 4 through the U-shaped bend 12.

[0044] Non-woven fabric layers 11 are laid above and below the water distribution pipe 4, wrapping the water distribution pipe 4 with the non-woven fabric layers 11. The non-woven fabric layers 11 have two functions: first, they effectively isolate the water distribution pipe 4 from the soil, preventing soil particles from entering the water distribution pipe 4 through the permeation holes and causing blockage; second, they provide a certain degree of insulation, further ensuring the normal flow of water in the water distribution pipe 4.

[0045] Therefore, the setting up of a microbial cultivation and distribution system for gray water treatment can provide a good environment for the normal growth and reproduction of microorganisms, so that microorganisms can effectively decompose organic matter in sewage, thereby avoiding the problem of biological enrichment; at the same time, it ensures that the treated gray water can be distributed to the farmland environment in a timely and rapid manner, thereby realizing the rapid absorption of inorganic salts by plant roots, thereby ensuring the effectiveness of sewage treatment distribution.
