[0002] In rural areas, the traditional method of rainwater and sewage treatment is usually mixed treatment, that is, rainwater and sewage are collected and discharged through the same pipe. This mixed treatment method will cause sewage treatment facilities to overload due to the surge in rainwater during the rainy season, reduce sewage treatment efficiency, and may even cause overflow and cause environmental pollution. At the same time, this method cannot make full use of rainwater resources, resulting in a large amount of precious rainwater being directly discharged into rivers or oceans, and failing to be effectively collected and used.

[0026] The rainwater utilization and discharge system 5 described in the utility model includes a water storage tank and a filtering mechanism 7, which are used to store and process rainwater for irrigation or other purposes, or safely discharge it to natural water bodies. The filtering mechanism 7 is arranged in the water storage tank.

[0027] A pipeline 8 is connected between the water storage tank and the sewage treatment device of the utility model, and a control valve 9 is provided on the pipeline 8.

[0028] Specifically, the working principle of the utility model is as follows:

[0029] (1) Rainwater collection system: Use roof gutters and ground drainage channels to collect rainwater from roofs, courtyards, roads and other surface locations. Roof gutters collect rainwater from the roof, while ground drainage channels collect rainwater from the ground. The rainwater is directed to the diversion well 2 through rainwater pipes, thereby quickly and effectively collecting rainwater, reducing surface runoff and preventing flooding.

[0030] (2) Diversion well: Located at the intersection of the rainwater pipe and the sewage collection pipe 3. The diversion well 2 is equipped with one or more well chambers with automatic or manual valves to adjust the flow direction of rainwater and sewage according to the water flow. When the amount of rainwater is large, the valve is adjusted to make the rainwater flow to the storage tank or drainage channel, reducing the load on the sewage treatment system. It effectively separates rainwater and sewage to ensure that the system treats water flow as needed.

[0031] (3) Sewage collection pipelines and sewage treatment plants: collect domestic sewage and livestock and poultry wastewater from residential and public facilities, and transport them to sewage treatment plants through pipelines. The sewage is centrally treated to meet certain discharge standards or used for farmland irrigation to prevent water pollution and environmental pollution.

[0032] (4) Rainwater utilization and discharge system: The water storage tank collects rainwater diverted through the diversion well 2 for irrigation or other purposes. The filtering mechanism 7 is located in the water storage tank to further filter the rainwater and remove residual solids and impurities.

[0033] (5) Control unit: adjusts the opening and closing of the valve in diversion well 2 according to real-time data to optimize the efficiency of rainwater and sewage diversion.

[0034] (6) Pipeline and control valve: The water storage tank and the sewage treatment device are connected by pipeline 8, and a control valve 9 is provided on the pipeline 8. The flow direction of rainwater and treated sewage is controlled, and irrigation or discharge is carried out as needed.

[0035] Through this system, rural areas can effectively manage rainwater and sewage, reduce environmental pollution, improve water resource utilization efficiency, and support sustainable water resource management and agricultural development. The specific workflow of this system is as follows:

[0036] When it starts to rain, the rainwater is first collected by the roof trough and the ground water collection channel. The collected rainwater is initially filtered through the filtering mechanism 7, such as a filter net or grid, which is arranged at the entrance of the rainwater collection system 1. This step is intended to intercept large particle pollutants such as leaves and debris to prevent them from entering the subsequent system and causing blockage. The filtered rainwater flows into the diversion well 2, and the destination of the rainwater can be determined by the automatic or manual valve in the diversion well 2 according to the rainwater flow rate and the current processing capacity of the system. The rainwater can be discharged directly to the rainwater utilization and discharge system 5, or it can be directed to the sewage treatment facility when necessary. The treated rainwater is stored in the water storage tank, and the filtering mechanism 7 in the water storage tank performs secondary filtration on the rainwater to ensure that the water quality meets the requirements for irrigation and other purposes. The treated rainwater can be used for farmland irrigation, landscaping, etc., effectively utilizing rainwater resources.

[0037] Domestic sewage and livestock and poultry wastewater flow into the sewage treatment plant through the sewage collection pipe 3 to avoid mixing with rainwater. In the sewage treatment plant, the sewage is continuously treated by the primary sedimentation tank 41, the biological treatment device 42 (biofilter or activated sludge system) and the disinfection device 43 to meet the standards for discharge or reuse.

[0038] The entire system monitors the flow rate, quality and operation status of rainwater and sewage in real time through the control unit 6. The control unit 6 automatically adjusts the opening and closing of the valve in the diversion well 2 according to the collected data, optimizes the efficiency of rainwater and sewage diversion, and ensures the efficient and stable operation of the system. Finally, the treated sewage passes through the control valve 9 and is safely discharged or used for reuse such as farmland irrigation as needed, completing the recycling of water resources.

[0039] Through the above process, the rural rainwater and sewage transformation and diversion system of the utility model effectively realizes the collection, filtration, storage and utilization of rainwater, as well as the collection, treatment and safe discharge or reuse of sewage, which significantly improves the utilization efficiency of water resources and the level of environmental protection.
