Problems solved by technology

However, the above-mentioned processing methods do not build a relatively closed circular ecological chain, and require more human intervention
At the same time, the economic value of nitrogen and phosphorus elements and the landscape functions created by the water ecosystem are not fully utilized.
[0003] The current treatment of non-point source pollution in rural areas, especially the treatment of black and odorous water bodies in village ponds, mostly focuses on the simple "water control" level, and has not tapped its landscape function

Embodiment 1

[0023] Embodiment 1. Ecological Landscape Pond System in Villages Using Water Nitrogen and Phosphorus Resources

[0024] The invention provides a village ecological landscape pond system ( figure 1 ). The implementation location is Shanghuangsha Village, Xihe Town, Dapu County, Guangdong Province. The specific steps are as follows:

[0025] 1) Diversion ditches: Clean up the original surface runoff flow paths and ditches, but keep the herbaceous vegetation in the ditches, and set up grit chambers with length, width and depth of 2m, 1m and 1m respectively at the ditches entering the pond.

[0026] 2) Landscape modeling treatment: On the basis of the original shape of the pond, the upper and lower ponds are respectively transformed into fan-shaped and circular shapes.

[0027] 3) Capacity expansion treatment: According to the local rainfall and the size of the catchment area above the pond, the original pond is expanded. The bottom of the expanded pond presents a configuration...

Abstract

The invention discloses a village ecological landscape pond system which can be used for intercepting and storing rural house domestic sewage and rainfall surface runoff on site and carrying out resource utilization treatment, so as to effectively reduce the pollution of village sewage to surrounding water bodies. A method comprises that a multi-element, circulating and stable water ecological system is constructed, human intervention is little, a certain landscape function and economic output are achieved, and the method is easily accepted and popularized by local common people. Compared witha traditional pond treatment mode for improving water quality, the village ecological landscape pond system has the advantages that 'beautiful village construction' elements, affiliated pavilions, galleries and cultural squares are integrated, and leisure and cultural life of local common people is enriched.

Description

technical field [0001] The invention belongs to the field of non-point source pollution disposal and ecological landscape, and specifically relates to a technology for utilization of nitrogen and phosphorus resources in water bodies and landscape effects, especially to a technology for landscape water ecosystems used in the process of sewage treatment in village ponds Build and run. Background technique [0002] At present, due to poor management of a considerable number of village ponds, the water body is polluted and foul smelling, causing a large number of bacteria, mosquitoes and flies to breed, seriously affecting the surrounding environment and the quality of life of villagers. The main reason for the decline of water quality is that the content of nitrogen and phosphorus in the water body is high, and the water body presents eutrophication. At present, the more commonly used pond sewage treatment methods include ditch interception method, plant absorption method, sed...
