Furthermore, in the channel body of the ecological ditch, a plurality of spoilers are arranged at intervals along the length direction of the channel body.
Through setting up the spoiler, when domestic sewage passes through ecological irrigation canals and ditches, can delay the velocity of flow of rivers, increase the flow time of sewage in ecological irrigation canals and ditches.
Further, the aquatic plants in the pond include myriophyllum viridis, cattail and reed; the planting density of the myriophyllum viridis is 200-300 roots/m 2 The planting density of the cattail is 30-40 plants/m 2 The planting density of the reed is 6-10 plants/m 2 。
The foxtail green algae, the cattail grass and the reed are planted in the pond, so that the domestic sewage can be purified for the second time, and meanwhile, the foxtail green algae, the cattail grass and the reed after being mature can be used as feed for cattle and sheep to eat after being harvested.
Furthermore, a drainage pipeline is embedded in the paddy field, a water inlet of the drainage pipeline is positioned in the paddy field, and the drainage pipeline can discharge redundant water in the paddy field out of the whole circulating system.
Through setting up drainage pipe, the gathering has more water in the paddy field, and drainage pipe can be with the whole circulation system of unnecessary water discharge in the paddy field, prevents to take place the waterlogging.
Furthermore, the crops planted in the paddy field are rape or rice; when the rape or the rice needs to be irrigated, the rape or the rice is irrigated through the purified water in the pond.
The rape or rice is irrigated, so that the sewage is recycled after being purified.
The invention has the beneficial effects that:
1. the myriophyllum pratense is arranged in the canal body of the ecological ditch, so that mineral ions such as nitrogen, phosphorus and the like in sewage can be absorbed; meanwhile, the myriophyllum viridis still has a good phosphorus removal effect under the low-temperature condition in winter, so that the defect that the phosphorus removal effect of common aquatic plants is poor under the low-temperature condition in winter is overcome.
2. The first back that purifies of sewage through ecological irrigation canals and ditches, during the pond of discharging into, the aquatic plant in the pond can carry out the second time to sewage and purify, and the purified water after purifying twice can be watered meadow and paddy field to this messenger's purified water can obtain the use.
