Abstract

The invention discloses an ecological ditch system, and relates to the technical field of agricultural non-point source pollution control engineering. The ecological ditch system is used for solving the technical problems that in an ecological ditch system in the prior art, the economic benefits of phytocoenosium are low, engineering construction cost is too high, the loss quantity of nitrogen and phosphorus nutrient elements in the vegetable field planting process is large, and surrounding water eutrophication is serious. The ecological ditch system comprises a ditch body. The bottom of the ditch body is of a multi-section structure with alternate concave parts and convex parts. Landscape plants, aquatic vegetables and water purification plants are planted in the multi-section structure. Slope protection plants and aquatic vegetables are planted on side walls of the ditch body. The bottom of the ditch body is arranged to be of the multi-section structure with the alternate concave parts and convex parts, and therefore the meandering performance of the ditch body can be increased, the hydraulic retention time can be prolonged, and the absorption efficiency of the ecological ditch system on the nitrogen and phosphorus nutrient elements can be improved. The ecological ditch system is mainly applied to construction of the ecological ditch system for controlling agricultural non-point source pollution.

Description

technical field [0001] The invention relates to the technical field of agricultural non-point source pollution control engineering, in particular to an ecological ditch system. Background technique [0002] Agricultural non-point source pollution refers to the non-point source pollution formed when pollutants in farmland enter water bodies through farmland surface runoff, soil inflow, farmland drainage and underground seepage during precipitation or irrigation during agricultural production activities. Among them, nitrogen and phosphorus discharged from agricultural sources is the main cause of water eutrophication. Among the many engineering measures for the control of agricultural nitrogen and phosphorus pollution, ecological ditches have high nitrogen and phosphorus removal rates and good landscape ecological effects, so they have become a research hotspot at home and abroad. [0003] In recent years, there have been many studies on farmland ecological ditches, mainly th...
