Detailed Description
In order to make the technical field of the present invention better understand the scheme of the present invention, the following detailed description of the embodiments of the system of the present invention is made with reference to the accompanying drawings.
With reference to fig. 1, the system sequentially comprises a plant covering soil layer, a gravel water distribution layer, a microbial soil layer, a permeable pebble layer and an impermeable layer from top to bottom, wherein a water distribution system is arranged in the gravel water distribution layer and connected with a high-level water inlet tank, the water distribution system comprises a main water distribution pipe and a plurality of water distribution pipes, the main water distribution pipe is transversely arranged, the water distribution pipes are arranged on the main water distribution pipe and communicated with the water distribution pipes, the main water distribution pipe is communicated with the high-level water inlet tank, and a plurality of water distribution holes are formed in the periphery of each water distribution pipe. The gravel water distribution layer has larger gap rate, and the water permeable layer is formed by controlling the particle size of the gravel. Meanwhile, the upper vegetation absorption mainly depends on the capillary action of the soil on the upper layer and the adsorption capacity of the root system of the vegetation, the lower part forms the diversion action through the pressure bearing action and the natural drainage and pressure relief of the lower part, and the gravel water distribution layer can not block the water distribution pipe. The permeable pebble layer is connected with a water collecting well through a water collecting pipeline. The microbial soil layer is provided with aggregates with different particle sizes, and the harmful substances in the sewage are removed by combining different soils, the aggregates with different particle sizes and microbial carrier cenobium; the microbial soil layer is provided with a plurality of deep breathable pipelines which are pre-embedded in advance, the top end of each deep breathable pipeline extends out of the plant covering soil layer, and a plurality of air holes are formed in the periphery of each deep breathable pipeline. The ventilating pipeline is a vertical pipeline, the inside of the pipeline is still in a hollow state after being installed and backfilled, air naturally enters the deep soil part through the pipeline, the position where the pipeline arrives is a ventilating point source, and the upper pipe orifice is higher than the ground and is shielded and protected by adopting a protection measure. The surface of the anti-seepage layer is provided with an anti-seepage film, so that the underground water and the surrounding water sources are independent, and the invasion and seepage of the external water body are isolated. The water permeable pebble layer is provided with a water collecting ditch, the water collecting ditch is arranged in the pebble layer, the water permeable pebble layer is a skeleton layer and a water permeable layer in essence, and the water collecting ditch is a flow guide ditch and plays a role in guiding water flow in the pebble layer from irregular flow direction to a final water outlet direction and guiding water to a water collecting well for agricultural irrigation, greening utilization or discharge.
