Description

Technical Field

[0001] This utility model relates to the field of rural domestic sewage treatment technology, specifically a device for the resource utilization of treated wastewater from rural domestic sewage treatment. Background Technology

[0002] While rural economic levels have improved, pollution has also intensified. Domestic sewage, a major type of rural pollution, is increasingly causing point-source and non-point-source pollution due to the lack of standardized management and treatment solutions, resulting in varying degrees of pollution of soil and surface water.

[0003] On the one hand, the discharge standards of rural sewage treatment facilities are lower than those of urban sewage treatment plants. Moreover, the receiving water bodies of rural sewage treatment facilities are mostly small water bodies in the surrounding area with small water environment capacity. The entry of effluent into the receiving water bodies increases their pollution load and increases the risk of water quality deterioration. On the other hand, the effluent from existing rural sewage treatment facilities is mostly discharged directly. The utilization of effluent is mostly carried out in unorganized forms such as flood irrigation and artificial irrigation, resulting in low utilization rate.

[0004] Therefore, it is necessary to develop a device for the resource utilization of wastewater from rural domestic sewage treatment to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for the resource utilization of wastewater from rural domestic sewage treatment, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rural domestic sewage treatment wastewater resource utilization device, comprising a partitioned plot and a water storage tank. Multiple soil moisture content monitors are installed inside the partitioned plot, and a central intelligent control center is installed outside the partitioned plot. The soil moisture content monitors transmit soil moisture content values ​​to the central intelligent control center. The water storage tank is connected to a booster pump via pipelines. The booster pump is sealed to a main pressure water distribution pipe via pipelines. An electric valve is installed on the main pressure water distribution pipe. The main pressure water distribution pipe is sealed to a branch pressure water distribution pipe via pipelines. Infiltration components are installed on both sides of the branch pressure water distribution pipes.

[0007] Preferably, the infiltration component includes a permeable geotextile layer, a three-dimensional material structure cladding layer, and a perforated pressure pipe. The three-dimensional material structure cladding layer is wrapped around the outer surface of the perforated pressure pipe, and the permeable geotextile layer is wrapped around the outer surface of the three-dimensional material structure cladding layer.

[0008] Preferably, the central intelligent control center can send an opening signal to the electric valve, and the pressure in the pipeline section between the booster pump and the electric valve decreases, automatically triggering the booster pump to start.

[0009] Preferably, the central intelligent control center can send a valve-closing signal to the electric valve, and if there is no pressure drop in the pipeline section between the booster pump and the electric valve, the booster pump will be automatically triggered to shut down.

[0010] Preferably, a pipe plug is installed at one end of the percolation assembly.

[0011] Preferably, one end of the water storage tank is connected to a tailwater discharge pipe.

[0012] Preferably, the other end of the water storage tank is sealed to a receiving water body via an overflow pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model lays infiltration components with special functions on the target plot, uses an intelligent system to analyze the soil moisture content of different plots, and irrigates the wastewater treatment facility tailwater at different frequencies as needed, so as to ensure that the water required for plant growth is met without over-irrigation, while providing nutrients such as nitrogen and phosphorus for plant growth, and reducing the amount of tailwater entering the surrounding water bodies and reducing the risk of water quality deterioration in the surrounding water bodies.

[0015] (2) This utility model sets up an infiltration component and a soil moisture monitor in the target plot as required. The soil moisture monitor feeds the monitoring value back to the central intelligent control center. The central intelligent control center analyzes the data transmitted back from the target plot. When the irrigation conditions are met, the central intelligent control center transmits a signal to the electric control valve to open the electric control valve. Subsequently, the pressure in the pipeline from the electric valve to the booster pump section decreases, and the booster pump starts automatically, transporting the tailwater stored in the water storage tank to the target plot for irrigation through the infiltration component. During this period, the soil moisture monitor transmits the monitoring value back to the central intelligent control center in real time for data analysis. After the water requirements of the plot are met, the electric valve and booster pump are automatically closed, and irrigation of the target plot is stopped. It has the advantages of convenient intelligent control and high degree of automation.

[0016] (3) This utility model can reduce the risk of rural water environment deterioration caused by the tailwater of rural sewage treatment facilities, reduce the risk of rural small water bodies evolving into black and odorous water bodies, and save water resources and appropriately reduce the amount of chemical fertilizers by making efficient use of tailwater.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-2 This utility model provides an embodiment of a rural domestic sewage treatment wastewater resource utilization device, including a partitioned plot 11 and a water storage tank 2. Multiple soil moisture content monitors 9 are installed inside the partitioned plot 11, and a central intelligent control center 10 is installed outside the partitioned plot 11. The soil moisture content monitors 9 are used to transmit the soil moisture content value to the central intelligent control center 10. The water storage tank 2 is connected to a booster pump 3 through a pipeline. The booster pump 3 is sealed to a pressure water distribution main pipe 4 through a pipeline. An electric valve 5 is installed on the pressure water distribution main pipe 4. The pressure water distribution main pipe 4 is sealed to a pressure water distribution branch pipe 6 through a pipeline. Infiltration components 7 are installed on both sides of the pressure water distribution branch pipe 6.

[0022] Furthermore, the infiltration component 7 includes a permeable geotextile layer 14, a three-dimensional material structure cladding layer 15, and a perforated pressure pipe 16. The three-dimensional material structure cladding layer 15 is wrapped around the outer surface of the perforated pressure pipe 16, and the permeable geotextile layer 14 is wrapped around the outer surface of the three-dimensional material structure cladding layer 15. The three-dimensional material structure cladding layer 15 has a water-permeable function, and the permeable geotextile layer 14 has the function of being permeable to water and able to block particulate matter.

[0023] Furthermore, the central intelligent control center 10 can send an opening signal to the electric valve 5, causing the pressure in the pipe section between the booster pump 3 and the electric valve 5 to decrease, automatically triggering the booster pump 3 to start. When the soil moisture content is low to the set limit, the central intelligent control center 10 sends an opening signal to the electric valve 5, causing the pressure in the pipe section between the booster pump 3 and the electric valve 5 to decrease, automatically triggering the booster pump 3 to start, and delivering tailwater to the pressure distribution main pipe 4 and pressure distribution branch pipe 6 set in the partitioned plot 11. The tailwater enters the soil through the infiltration components 7 set on both sides of the pressure distribution branch pipe 6 to replenish the soil moisture content.

[0024] Furthermore, the central intelligent control center 10 can send a valve-closing signal to the electric valve 5. When there is no pressure drop in the pipe section between the booster pump 3 and the electric valve 5, the booster pump 3 is automatically triggered to shut down. The soil moisture content monitoring instruments 9 installed in each plot 11 transmit the soil moisture content value back to the central intelligent control center 10 in real time for comprehensive data analysis. When the soil moisture content reaches the set upper limit value, the central intelligent control center 10 sends a valve-closing signal to the electric valve 5. When there is no pressure drop in the pipe section between the booster pump 3 and the electric valve 5, the booster pump 3 shuts down automatically, and the infiltration component 7 stops replenishing water to the soil.

[0025] Furthermore, a pipe plug 8 is installed at one end of the percolation component 7.

[0026] Furthermore, one end of the water storage tank 2 is connected to the tailwater discharge pipe 1.

[0027] Furthermore, the other end of the water storage tank 2 is sealed to the receiving water body 13 via an overflow pipe 12.

[0028] Working principle: In use, the system consists of three subsystems: intelligent control system, irrigation system, and infiltration system. After the wastewater is treated to meet the standards, the effluent enters the storage tank 2 through the effluent discharge pipe 1 to store a fixed amount of effluent. Soil moisture content monitoring instruments 9 (with signal transmission function) are set at different locations in the target zone plot 11 according to the set requirements. The monitoring instruments 9 transmit the soil moisture content value to the central intelligent control center 10 at regular intervals. The central intelligent control center 10 performs comprehensive analysis on the data returned by each set of soil moisture content monitoring instruments 9 set in the zone plot 11. When the soil moisture content is low to the set limit, the central intelligent control center 10 sends a valve opening signal to the electric valve 5. The pressure in the pipe section between the booster pump 3 and the electric valve 5 decreases, automatically triggering the booster pump 3 to start and deliver effluent to the pressure water distribution main pipe 4 and pressure water distribution branch pipe 6 set in the zone plot 11. The effluent enters the soil through the infiltration components 7 set on both sides of the pressure water distribution branch pipe 6 to replenish the soil moisture content. At the same time, the soil moisture content monitoring instruments 9 installed in each plot 11 transmit the soil moisture content value back to the central intelligent control center 10 in real time for comprehensive data analysis. When the soil moisture content reaches the set upper limit value, the central intelligent control center 10 sends a valve closing signal to the electric valve 5. There is no pressure drop in the pipeline section between the booster pump 3 and the electric valve 5, the booster pump 3 automatically shuts down, and the infiltration component 7 stops replenishing water to the soil.

[0029] The infiltration component 6 consists of three parts: a permeable geotextile layer 14, a three-dimensional material structure cladding layer 15, and a perforated pressure pipe 16. Specifically, the pressure pipe is formed by drilling circular holes of a set diameter at certain horizontal and vertical intervals. The pipe is wrapped with a three-dimensional material structure cladding layer 15 with a certain structural strength (which has a water-permeable function). The three-dimensional material structure cladding layer 15 is then wrapped with a permeable geotextile layer 14 that is both permeable and can block particulate matter.

[0030] Considering that the water demand of the plot is intermittent or that the water output of the water storage tank 2 is interrupted due to facility maintenance, while the water intake of the tailwater discharge pipe 1 is continuous, an overflow pipe 12 is installed in the water storage tank 2 as required. Excess tailwater enters the surrounding receiving water body 13 through the overflow pipe 12. If the overflow pipe 12 is laid in the planting plot that needs water, the overflow pipe 12 can be designed as an infiltration component 6.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
