Description

An integrated multi-media filtration rainwater recycling device Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically an integrated multi-media filtration rainwater recycling device. Background Technology

[0002] Rainwater harvesting is an effective water resource management method that involves multiple stages such as rainwater collection, storage, treatment and reuse. Generally, rainwater harvested and reused is mainly used for greening irrigation, industrial water use and domestic toilet flushing.

[0003] The most common existing rainwater harvesting device is to bury a rainwater collection tank underground and connect it to a sewer well. This allows rainwater to flow into the rainwater collection tank through the sewer well. During the introduction process, the rainwater entering the collection tank is filtered by the installed filter components. Finally, the rainwater in the collection tank is pumped out by a water pump and transported to the corresponding location for use.

[0004] However, existing rainwater harvesting and filtration devices often adopt a split layout, that is, they are filtered through multiple filters, which results in a large footprint. Therefore, based on the above technical problems, an integrated multi-media filtration rainwater harvesting and utilization device was designed. Summary of the Invention

[0005] To overcome the problem of large size in existing technologies, this utility model proposes an integrated multi-media filtration rainwater recycling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an integrated multi-media filtration rainwater recycling device, including an installation cabinet, in which a multi-media filter and a dosing assembly are connected by pipes. The multi-media filter is provided with an inlet pipe and an outlet pipe. The dosing assembly includes a clarifying agent tank and a long-acting disinfectant tank. The clarifying agent tank is connected to the inlet pipe by a pipe, and the long-acting disinfectant tank is connected to the outlet pipe by a pipe.

[0007] Working Principle: The filter in this application is a multi-media filter. A multi-media filter is a filtration device that uses two or more filter media to fill a container with various filter media. It effectively removes suspended impurities and clarifies the water by passing highly turbid wastewater through a certain thickness of granular or non-granular material. The principle is that when raw water passes through the filter media from top to bottom, suspended solids in the water are intercepted, settled, diffused, and retained on the filter layer surface by hydrodynamic forces. When water flows into the middle of the filter layer, the sand particles in the filter media are more densely packed, giving more opportunities for microparticles in the water to pass through. When the water collides with sand particles, the flocculent matter, suspended solids, and sand particles adhere to each other, and impurities in the water are trapped in the filter media layer, thus obtaining clear water. At the same time, a dosing component is added. The clarifying agent tank is connected to the inlet pipe through a pipeline, and the long-lasting disinfectant tank is connected to the outlet pipe through a pipeline. That is, the clarifying agent is added before the filter. The clarifying agent causes impurities in the rainwater to form large flocs before entering the filter, improving the filtration effect. The long-lasting disinfectant is added after the water passes through the filter. The long-lasting disinfectant in this application is a chlorine-based agent, which has a long-lasting disinfection effect.

[0008] Preferably, the inlet pipe is equipped with a rapid pipe mixer one, the outlet pipe is equipped with a rapid pipe mixer two, the clarifying agent tank is connected to the rapid pipe mixer one via a pipe, and the long-acting disinfectant tank is connected to the rapid pipe mixer two via a pipe.
