With the rapid development of rural areas, the rapid improvement of the living standard of vast rural people, and the development of industries such as rural livestock and poultry breeding, aquaculture, agricultural and sideline product processing and the like, the discharge amount of rural domestic sewage is continuously increased, and the ecological balance of rural areas is seriously damaged. The rural domestic sewage mainly comes from excrement and flushing water thereof, bathing sewage and kitchen sewage in the living process of residents and sewage generated in the rural decentralized breeding process. The rural domestic sewage quality has the characteristics of high N and P content, strong biodegradability, less toxic and harmful substances containing heavy metals and the like, relatively less discharge amount of each household in discharge, larger water quality fluctuation, dispersed discharge points, more points and more areas, difficult collection, no sewage treatment system in most rural areas and the like. Therefore, the discharge of the sewage discharge outlet of the rural river channel is easy to cause pollution to the river channel.
In the prior art, the rural river channel is ecologically treated by adopting an artificial wetland mode. The artificial wetland comprises a surface flow wetland and an undercurrent wetland, wherein the undercurrent wetland comprises a horizontal flow artificial wetland and a vertical flow artificial wetland, and compared with the surface flow wetland, the horizontal flow artificial wetland has high hydraulic load, better removal effect on pollutants such as BOD, COD, SS, heavy metals and the like, no stink and mosquito and fly breeding, and is the most widely adopted wetland form at present. But the control is relatively complex, and the N and P removing effect is not as good as that of the vertical flow artificial wetland. The vertical flow wetland is divided into a downward flow wetland and an upward flow wetland, the downward flow wetland is relatively simple and more common in operation, and sewage flows in from the surface of the wetland, flows through a wetland matrix layer from top to bottom and flows out from the bottom. The upward flowing water flow direction is opposite. Because oxygen can enter the wetland system through atmospheric diffusion and plant transmission, the oxygen charging inside the wetland system is more sufficient, which is beneficial to the growth of aerobic microorganisms and the proceeding of nitration reaction, and the nitrogen and phosphorus removal effect is better. The event designs one kind and can synthesize two kinds of wetland advantages, and the construction of being convenient for simultaneously has very important meaning to the processing structure that drain purification monitoring ability is high.
