Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a modular container house with integrated rainwater collection and treatment and a treatment method. Background Technology

[0002] Modular container houses, as a modern building form, are widely used in temporary housing, office, and emergency rescue scenarios due to their advantages of rapid assembly, mobility, and reusability. However, existing modular container houses have significant shortcomings in terms of water resource utilization and environmental protection.

[0003] Currently, most modular container houses have simple roof drainage systems, with rainwater simply draining directly to the ground via natural slopes, resulting in a significant waste of water resources. Even those designs that attempt to collect rainwater often only involve simple storage, lacking effective treatment processes. Untreated rainwater contains dust, impurities, microorganisms, and even pollutants; direct use may harm human health and damage equipment (such as clogging pipes), while indiscriminate discharge can pollute surrounding soil and water bodies, disrupting the ecological balance. Therefore, existing technologies struggle to achieve clean, safe, and efficient recycling of rainwater resources, hindering improvements in the energy-saving and environmental performance of modular container houses. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a modular container house and treatment method that integrates rainwater harvesting and treatment. This container house integrates a highly efficient rainwater harvesting, multi-stage purification, and diversified utilization system, enabling autonomous collection, purification to standards, and recycling of rainwater resources. This improves water resource utilization efficiency and reduces dependence on municipal water supply and potential environmental pollution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Firstly, this application provides a modular container house with integrated rainwater harvesting and treatment, comprising:

[0007] Rainwater harvesting systems, rainwater treatment systems, and rainwater utilization systems;

[0008] The rainwater harvesting system includes an annular water collection trough installed on the roof of the container house, with the roof panels inclined toward the annular water collection trough; the bottom of the annular water collection trough is provided with a drain outlet, which is connected to the inlet of the rainwater treatment system through a drain pipe;

[0009] The rainwater treatment system includes at least a sedimentation tank and a filtration tank connected in sequence; the sedimentation tank is used to receive and settle rainwater from the drainage pipe; the filtration tank is equipped with a filter medium for filtering the settled rainwater.

[0010] The rainwater utilization system includes a water supply network connected to the outlet of the filter tank, and distributes the treated water to at least one water point inside the container house.

[0011] To enhance the structural strength of the collection trough to withstand the load of rainwater and debris, and to optimize the water flow path to reduce siltation, in some optional embodiments, the annular collection trough has a U-shaped cross-section, with its inner side arranged along the roof steel beams. The drainage pipe includes at least one water supply pipe and multiple diversion pipes. The multiple diversion pipes are used to collect water discharged from the drain outlet and backflow it to the water supply pipe, which then guides it to the inlet of the sedimentation tank.

[0012] To address the issue of rainwater carrying leaves and large particles during the initial collection phase, in some optional embodiments, the rainwater collection system further includes a filtration device located within the annular collection trough; the filtration device includes a filter mesh for intercepting debris and a filter cotton core for adsorbing pollutants.

[0013] In order to deeply remove residual fine suspended particles, odors, pigments and some organic pollutants from rainwater, in some optional embodiments, the outlet of the sedimentation tank is higher than the inlet of the filtration tank, and the filter media in the filtration tank includes a quartz sand filter layer and an activated carbon filter layer.

[0014] In order to completely kill harmful microorganisms such as bacteria and viruses that may exist in rainwater, in some optional embodiments, the rainwater treatment system also includes a disinfection tank connected to the filtration tank; the disinfection tank is equipped with ultraviolet disinfection lamps for disinfecting rainwater.

[0015] To address the issue of incomplete disinfection due to dead zones in water flow during static disinfection, in some optional embodiments, the disinfection pool is also equipped with a stirring device to ensure that rainwater is evenly exposed to ultraviolet radiation.

[0016] In order to monitor the disinfection effect in real time and ensure the safety and reliability of the effluent water quality, in some optional embodiments, the disinfection tank is also equipped with a water quality detection sensor for real-time monitoring of the microbial indicators of rainwater.

[0017] In order to maximize the use of treated rainwater and conserve municipal water resources, in some optional embodiments, the water use points of the rainwater utilization system include at least one of toilet flushing equipment, greening irrigation interface and cleaning water tap.

[0018] To address the imbalance between the immediate supply of rainwater after disinfection and intermittent water demand, some alternative implementations include a water storage tank located between the disinfection pool and the water supply network.

[0019] To achieve compact system integration, facilitate transportation and rapid deployment, in some optional embodiments, the rainwater treatment system's storage tank, sedimentation tank, filtration tank and disinfection tank are integrated inside the container house.

[0020] Secondly, this application provides a method for rainwater collection, treatment, and utilization in modular container houses, characterized by comprising the following steps:

[0021] S1: Rainwater harvesting and primary filtration: By constructing the roof of the modular container house as a sloping surface that is high in the middle and low around the edges, rainwater falling on the roof naturally flows into a ring-shaped water collection trough set at the edge of the roof; during the process of rainwater flowing into the water collection trough, it passes through coarse filtration and fine filtration in sequence to remove large-sized debris and some pollutants.

[0022] S2: Multi-stage purification treatment: The rainwater that has passed the primary filtration will be subjected to sedimentation, filtration and disinfection treatment in sequence;

[0023] The sedimentation process involves allowing rainwater to settle in a sedimentation tank to separate suspended particles.

[0024] The filtration process involves passing rainwater through a filter medium that contains at least a layer of quartz sand and a layer of activated carbon to remove fine particles, odors, and organic pollutants.

[0025] The disinfection process involves irradiating rainwater flowing through a disinfection pool with ultraviolet light to inactivate microorganisms within it.

[0026] S3: Storage and Distribution: The disinfected rainwater is stored and distributed to at least one water point within the modular container house via a water pipe network for utilization.

[0027] The beneficial effects of the modular container house and treatment method that integrates rainwater harvesting and treatment disclosed in this application may include, but are not limited to:

[0028] 1. Achieves highly efficient collection and utilization of rainwater resources, resulting in significant water-saving benefits: Through innovative roof slope design and U-shaped ring-shaped water collection troughs, the collection efficiency of roof rainwater is greatly improved (up to 90% or more), transforming previously wasted rainwater resources into a stable alternative water source. The treated rainwater can be used for toilet flushing, landscaping, and cleaning, saving 30%-50% of municipal domestic water consumption. It is particularly suitable for water-scarce areas or temporary facilities, demonstrating outstanding economic and environmental benefits.

[0029] 2. A complete, efficient, and integrable rainwater treatment process is provided to ensure water safety: Unlike simple storage methods, this invention integrates a multi-stage treatment chain of "physical interception + sedimentation + multi-stage filtration + ultraviolet disinfection." This process combination effectively removes suspended solids, organic matter, odors, and pathogenic microorganisms from rainwater, ensuring that the effluent quality consistently meets relevant requirements and is safe for various domestic uses, completely eliminating the health risks and equipment damage risks associated with directly using untreated rainwater.

[0030] 3. The system is highly integrated and modular, aligning with the core advantages of container houses: The collection, treatment, and utilization systems are all integrated within the standard container or the bottom module space, requiring no additional ground space and preserving the inherent advantages of container houses for rapid hoisting, transportation, and relocation. This "plug-and-play" design allows the rainwater recycling system to be used as a standard or optional module, seamlessly integrating with various container house products, greatly enhancing the product's added value and market competitiveness.

[0031] 4. The primary filtration design, combining coarse and fine filters, reduces the load on the core treatment unit and facilitates maintenance: A removable coarse filter mesh and fine filter core are installed at the inlet of the collection tank, effectively removing most solid debris and some pollutants at the source. This design not only prevents drainage pipe blockage but also significantly reduces sludge accumulation and filter media clogging in subsequent sedimentation and filtration tanks, extending the backwashing or maintenance cycle of the core treatment unit and lowering the long-term operation and maintenance costs of the system.

[0032] 5. Green and efficient disinfection method with no risk of secondary pollution: Ultraviolet disinfection is used as the final means of ensuring water quality safety. Compared with chemical disinfection methods such as adding chlorine, it has advantages such as instantaneous effect, no generation of toxic byproducts, and no change in the physicochemical properties of water. Combined with a stirring device to ensure uniform and thorough disinfection, and water quality sensors to monitor the process, a safe, green, and controllable disinfection assurance system is constructed.

[0033] 6. Flexible application scenarios and significant social and ecological benefits: This system can be used not only for conventional temporary office and residential modular units, but also plays a significant role in emergency scenarios such as earthquake relief, field construction, and large-scale event support. It provides emergency domestic water when municipal water supply is interrupted, enhancing the self-sufficiency of emergency facilities. Simultaneously, by reducing the direct discharge of unclean rainwater and conserving tap water, it alleviates pressure on urban pipe networks and natural water bodies from both the source and end, demonstrating positive ecological and environmental protection significance.

Detailed Implementation

[0041] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] like Figure 1-6 As shown, in the first aspect, a modular container house with integrated rainwater harvesting and treatment includes a rainwater harvesting system, a rainwater treatment system, and a rainwater utilization system.

[0044] To address the core technical problems of resource waste caused by direct rainwater discharge from existing container houses and the unsafe utilization of water that fails to meet quality standards after simple collection, this invention constructs a basic and complete integrated "collection-treatment-utilization" architecture. This scheme places the rainwater collection system on the roof of the container house, guiding rainwater through the roof structure to a ring-shaped collection trough 1, and then transporting it through six drainage pipes to the rainwater treatment system inside the container. The rainwater treatment system includes at least a sedimentation tank 13 for solid-liquid separation and a filtration tank for deep purification, ensuring that the rainwater receives basic treatment. The treated water is distributed to internal water points through the water pipe network 12 of the rainwater utilization system, realizing a closed loop from collection to utilization.

[0045] Rainwater falls onto the roof panels 7, which have a certain slope (towards the collection trough), and flows under gravity into the annular collection trough 1 surrounding the roof. The drain outlet at the bottom of the collection trough is connected to the inlet of the rainwater treatment system, namely the inlet of the sedimentation tank 13, via drain pipes 6. The rainwater settles in the sedimentation tank 13, separating most of the suspended particles. The supernatant flows into a connected filter tank, where it is further purified by the filter media's interception and adsorption. The purified water flows out from the outlet of the filter tank and connects to the main pipe of the water supply network 12. Branches of the network then connect to various pre-designated water usage points.

[0046] To enhance the structural strength of the water collection trough to withstand the load of rainwater and debris, and to optimize the water flow path to reduce siltation, the cross-section of the annular water collection trough 1 is set as U-shaped, with its inner side arranged along the roof steel beam. The U-shaped cross-section provides better structural stability, and its smooth arc surface facilitates the rapid collection of rainwater and its guidance to the drainage outlet.

[0047] It should be noted that the cross-section of the water collection tank can also adopt a V-shape or other geometric shapes that are conducive to water collection and have sufficient structural rigidity.

[0048] The six drainage pipes include at least one water supply pipe 5 and multiple guide pipes 4. The multiple guide pipes 4 are used to collect water discharged from the drain outlets and return it to the water supply pipe 5, which then guides it to the inlet of the sedimentation tank 13. The multiple guide pipes 4 are arranged in a shape that is lower in the middle and higher around the edges, relying on gravity to automatically guide and collect the water to the water supply pipe 5. Among the multiple guide pipes 4, some are arranged parallel below the annular water collection tank 1, so that all the water discharged from the several drain outlets on the annular water collection tank 1 can be received. At the same time, these guide pipes 4 below the annular water collection tank 1 are all inclined, and their lower ends are connected to the inlet of the guide pipe 4 connected to the water supply pipe 5.

[0049] To address the issue of rainwater carrying leaves and large particles during the initial collection phase, prevent blockages in the six drainage pipes, and reduce the load on subsequent treatment processes, a filtration device is installed within the annular collection tank 1. This device includes a filter mesh 2 (which can be a coarse filter mesh) and a filter cotton core 3 (which can be a fine filter cotton core). The coarse filter mesh first intercepts large debris, while the fine filter cotton core adsorbs some fine particles and dissolved pollutants, achieving primary purification of the rainwater.

[0050] The coarse filter mesh is typically detachably installed on the upper or middle part of the inlet side of the rainwater collection tank using clips or other means, to initially coarsely filter the incoming rainwater. The fine filter core can be placed downstream of the coarse filter mesh or near the drain outlet at the bottom of the collection tank to finely filter the rainwater that has passed through the coarse filter. Both are easy to clean or replace periodically.

[0051] As an alternative, the coarse filter mesh can be replaced by a metal mesh or plastic grid with different pore sizes; the fine filter core can be replaced by non-woven fabric, sponge or other porous adsorbent materials.

[0052] To thoroughly remove residual fine suspended particles, odors, pigments, and some organic pollutants from rainwater, the filter media in the filtration tank are configured to include a quartz sand filter layer 9 and an activated carbon filter layer 8. The quartz sand filter layer 9 primarily performs precision mechanical filtration, while the activated carbon filter layer 8 primarily performs physicochemical adsorption. Together, they significantly improve water clarity and safety.

[0053] Multi-layer filter media are typically filled in a graded manner within the filter tank. Water flows from top to bottom or through specific channels, passing sequentially through the quartz sand filter layer 9 and the activated carbon filter layer 8. The quartz sand layer intercepts fine particles, while the activated carbon layer adsorbs dissolved pollutants.

[0054] Filter media may also include zeolite, diatomaceous earth, or polymer filter media. The layering order of quartz sand and activated carbon can be adjusted according to the characteristics of the water quality.

[0055] To thoroughly eliminate potentially harmful microorganisms such as bacteria and viruses in rainwater and ensure that the treated rainwater meets the hygiene standards for domestic reclaimed water, the rainwater treatment system also includes a disinfection tank 14, within which ultraviolet disinfection lamps 10 are installed. Ultraviolet disinfection is highly efficient and produces no secondary pollution, making it suitable for integrated applications in modular container houses.

[0056] The effluent from the filtration tank enters the disinfection tank 14 through pipes or overflow. The ultraviolet disinfection lamp 10 is immersed in the water or installed in a light-transmitting sleeve within the water flow channel. When rainwater flows through its irradiation area, microorganisms are inactivated by ultraviolet light.

[0057] Disinfection methods can also employ technologies with disinfection effects, such as ozone generators, chlorine dioxide dosing devices, or ultrafiltration membranes.

[0058] To address the issue of incomplete disinfection caused by dead zones in the water flow during static disinfection, and to improve the uniformity and efficiency of ultraviolet irradiation, a stirring device is installed in the disinfection tank 14. This device circulates the water within the tank, ensuring that all water particles receive an effective dose of ultraviolet radiation.

[0059] A stirring device, such as a small submersible agitator or a pneumatic agitator, is installed at the bottom or side wall of the disinfection tank 14 to promote the circulation of the tank water during operation.

[0060] Alternatively, a pipe design that allows water to flow through the ultraviolet disinfection chamber in a specific turbulent state can be used to replace mechanical stirring.

[0061] To monitor the disinfection effect in real time and ensure the safety and reliability of the effluent water quality, the disinfection tank 14 is also equipped with water quality detection sensors, such as a residual chlorine sensor or a system linking an ultraviolet intensity monitor with a flow meter. This sensor provides feedback signals that can be connected to a controller for early warning or adjustment of the disinfection equipment's operating status.

[0062] The water quality sensor probe is submerged near the outlet of disinfection tank 14 to continuously monitor key water quality indicators and transmit the signals to the controller.

[0063] Of course, regular manual sampling and testing can be used as a supplement or alternative, but automated monitoring is more efficient and reliable.

[0064] To maximize the use of treated rainwater and conserve municipal water resources, the water usage points of the rainwater utilization system are configured to include at least one of the following: toilet flushing equipment, greening irrigation interface, and cleaning water tap. This covers the main non-potable water needs within the container house.

[0065] Water pipe network 12 is led out from the outlet of disinfection pool 14 and connected to the inlet valve of toilet in bathroom, quick irrigation connector reserved on the exterior wall or ground, and indoor faucet for cleaning through valves and branch pipes respectively.

[0066] Of course, water usage points can also be expanded to include air conditioning cooling water replenishment, fire-fighting backup water sources, etc., depending on the specific application scenario.

[0067] To ensure that rainwater flows smoothly to the collection trough at an appropriate speed, avoiding evaporation loss or water accumulation on the roof, and preventing splashing or erosion due to excessive flow velocity, the slope of the roof panel 7 is set to 3% to 5%. This slope range is optimized to achieve efficient water diversion.

[0068] The roof panel 7 is installed with a 3%-5% slope from the center or one side towards the drainage trough. Specifically, the slope can be adjusted within a certain range depending on the local rainfall intensity, but the basic principle remains the same.

[0069] To achieve compact system integration, facilitate transportation, and enable rapid deployment, the various tanks of the rainwater treatment system (sedimentation tank 13, filtration tank, and disinfection tank 14) are integrated within the modular space inside the container house or at the bottom (e.g., utilizing the container's mezzanine or a pre-reserved equipment compartment at the bottom). This design does not occupy additional external space, maintaining the integrity and mobility of the container house.

[0070] Each treatment tank is installed as a prefabricated module in a designated location within the enclosure, connected in series via pipes, and connected to the pipes of the collection and utilization systems.

[0071] The processing system can also be designed as a mobile processing station independent of the container, which can be connected to the container house via a quick interface, offering greater flexibility but slightly lower integration.

[0072] To address the imbalance between the immediate supply of rainwater after disinfection and intermittent water demand, and to serve as an emergency backup water source, thereby improving the stability and reliability of the system's water supply, a water storage tank 11 was added between the disinfection tank 14 and the water supply network 12. This water storage tank 11 stores rainwater that has completed all purification and disinfection processes, forming a clean water buffer container. The rainwater treatment system's water storage tank 11, sedimentation tank 13, filtration tank, and disinfection tank 14 are integrated within the container house.

[0073] Clean water from disinfection tank 14 is first injected into storage tank 11 through pipes. The outlet of storage tank 11 is connected to the main pipe of water supply network 12 via a water pump (or by gravity if the tank is located at a higher position). When water is used, the system prioritizes drawing water from storage tank 11. Storage tank 11 is usually equipped with a water level sensor. When the water level is lower than a set value, the water replenishment process from disinfection tank 14 to storage tank 11 can be automatically started; when storage tank 11 is full, the water intake will automatically stop.

[0074] It should be noted that the water storage tank 11 can be integrated into the bottom of the tank or attached to one side of the tank as an independent module.

[0075] Optionally, the water storage tank 11 can also be equipped with a pressurization device to facilitate water supply.

[0076] Secondly, this application also provides a method for rainwater collection, treatment and utilization in modular container houses, characterized by comprising the following steps:

[0077] S1: Rainwater collection and primary filtration: By constructing the roof of the modular container house as a sloping surface that is high in the middle and low around the edges, the rainwater falling on the roof naturally flows into the annular water collection trough 1 set at the edge of the roof; during the process of the rainwater flowing into the water collection trough, it passes through coarse filtration and fine filtration in sequence to remove large-sized debris and some pollutants.

[0078] S2: Multi-stage purification treatment: The rainwater that has passed the primary filtration will be subjected to sedimentation, filtration and disinfection treatment in sequence;

[0079] The sedimentation process involves allowing rainwater to settle in sedimentation tank 13 to separate suspended particles.

[0080] The filtration process involves passing rainwater through a filter medium that contains at least a layer of quartz sand and a layer of activated carbon to remove fine particles, odors, and organic pollutants.

[0081] The disinfection process involves irradiating rainwater flowing through the disinfection pool 14 with ultraviolet light to inactivate the microorganisms therein.

[0082] S3: Storage and Distribution: The disinfected rainwater is stored and distributed to at least one water point in the modular container house for use through the water pipe network 12.

[0083] The following section elaborates on the working principle of this application;

[0084] The modular container house described in this invention has a core working principle of constructing a closed-loop water circulation system from "source collection" to "deep purification" and then to "precise utilization", which realizes the self-sufficient management and application of rainwater resources within the building unit.

[0085] The workflow of the entire system is as follows:

[0086] Gravity collection and primary filtration: Rainwater falls onto the roof panel 7 with a specific slope (3%-5%) and rapidly flows outwards under gravity, where it is efficiently intercepted by the U-shaped annular water collection trough 1. During its flow into the collection trough, the rainwater first passes through a coarse filter mesh, intercepting large particles such as leaves and bird droppings; then it flows through a fine filter core, adsorbing some dust and dissolved pollutants, completing the initial physical purification during the collection process.

[0087] Multi-stage gradient purification: Rainwater, after initial filtration, flows through six drainage pipes and enters the integrated rainwater treatment system within the enclosure by gravity or pumping. The purification process follows a gradient principle of "physical sedimentation → media filtration → deep disinfection."

[0088] First, in sedimentation tank 13, the water flow speed is slowed down, and suspended solid particles such as silt and sand settle naturally in a static environment, achieving mud-water separation.

[0089] The supernatant then flows into the filtration tank, penetrating from top to bottom through the quartz sand filter layer 9 and the activated carbon filter layer 8. The quartz sand layer removes fine suspended solids through the mechanical interception of its tiny pores; the activated carbon layer, with its huge specific surface area and adsorption capacity, removes odors, pigments, and some organic pollutants, significantly improving the sensory indicators and safety of the water.

[0090] Finally, clear rainwater enters the disinfection tank 14. The ultraviolet disinfection lamps 10 inside the tank emit ultraviolet light of a specific wavelength, directly destroying the genetic material of bacteria, viruses, and other microorganisms flowing through the water, rendering them inactive and thus achieving safe water quality standards. A stirring device inside the tank ensures that the water flow is evenly irradiated, eliminating any disinfection dead zones; water quality sensors provide real-time monitoring, ensuring stable and reliable effluent quality.

[0091] Intelligent allocation and diversified utilization: Clean rainwater that has passed purification standards is stored in a disinfection pool 14 or an independent water storage tank 11 and then pressure-transmitted through a water pipeline network 12. The pipeline network system intelligently allocates water according to the functional zones of the container house, providing a stable supply to toilet flushing equipment to replace precious tap water for sanitation; supplying water to green irrigation interfaces to provide irrigation water for surrounding vegetation; or supplying water to cleaning faucets for miscellaneous uses such as floor cleaning and vehicle washing, fully covering non-potable water needs.

[0092] The system's components are organically connected through pipes, valves, and electrical control units (not fully shown in the figure) to form a highly automated, modular integrated water treatment and utilization unit, making each container house an independent water resource recycling node.

[0093] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
