Ecological circulation channel and pond treatment system for orchard tail water

Abstract

The invention discloses an ecological circulation channel and pond treatment system for orchard tail water. The ecological circulation channel and pond treatment system comprises an ecological circulation channel and an ecological pond. The ecological circulation channel is formed around an orchard. A first pipeline is arranged between the ecological circulation channel and the ecological pond forcommunication. A water pump is arranged on the first pipeline. Ground cover plants are planted on the earth surface of the orchard for covering. Slope protection trees are planted on the bank side ofthe ecological pond. A floating island is arranged in the ecological pond, and hydrophilic plants are planted on the floating island. According to the ecological circulation channel and pond treatment system for the orchard tail water, by adoption of the mode, the ground cover plants are used for primarily purifying the orchard tail water, and parts of nitrogen and phosphorus nutrient substancesand pesticide residues are removed; and then the tail water flows into the ecological circulation channel and is further purified through emergent aquatic plants and aquatic plants in the ecological circulation channel, excess water flows into the ecological pond, and accordingly a virtuous circle can be formed.

Description

technical field [0001] The invention relates to the technical field of environmental management, in particular to an ecological circulation ditch pond treatment system for orchard tail water. Background technique [0002] The use of biogas digesters can treat most of the solid waste and sewage on the farm, and produce organic fertilizers, but the organic fertilizers cannot be fully absorbed by the plants when they are put into the fields, and 5% to 10% of the nutrients pollute the water body through rainwater runoff. Moreover, fruit trees must be topdressed with a certain amount of nitrogen, phosphorus, and potassium compound fertilizers during the fruit expansion period, and the absorption and utilization rate of chemical fertilizers by fruit trees is no more than 70%, and the remaining 30% will flow into water bodies anytime and anywhere to pollute the environment. [0003] In addition, in order to prevent insects, some fruit trees are also sprayed with pesticides. When it...

[0002] The use of biogas digesters can treat most of the solid waste and sewage on the farm, and produce organic fertilizers, but the organic fertilizers cannot be fully absorbed by the plants when they are put into the fields, and 5% to 10% of the nutrients pollute the water body through rainwater runoff. Moreover, fruit trees must be topdressed with a certain amount of nitrogen, phosphorus, and potassium compound fertilizers during the fruit expansion period, and the absorption and utilization rate of chemical fertilizers by fruit trees is no more than 70%, and the remaining 30% will flow into water bodies anytime and anywhere to pollute the environment

[0003] In addition, in order to prevent insects, some fruit trees are also sprayed with pesticides. When it rains, pesticide residues will fall to the ground with the rain, which will also pollute the surface and groundwater. Improvements are needed.
