Embodiment 1

[0020] After a sewage treatment plant was built in the upstream of a water source in a city in Guizhou Province, the water quality of the water source was affected and the water quality declined. In order to protect the source of drinking water, a joint treatment system of surface flow artificial wetland and plant pond was adopted. Due to the terrain, an area of ​​100m× Constructed wetland of 100m, at the same time build a secondary plant pond, the area of ​​the plant pond is 300m 2 、500m 2 .

[0021] 1. The surface flow artificial wetland includes a water supply system, an anti-seepage system, a medium system, plants, etc.; both the first-level plant pond and the second-level plant pond are planted with landscape plants; both ponds are planted with submerged plants and spruces. Aquatic plants, among them, the submerged plants selected for the first-level plant ponds are Heliconia spicaculata, and the submerged plants for the second-level plant ponds are Hydrilla verticillium...

Abstract

The invention discloses a constructed wetland and plant pond joint treatment system for tail water advanced treatment. The constructed wetland and plant pond joint treatment system comprises a surface flow constructed wetland, a first-stage plant pond and a second-stage plant pond, which are arranged in a stepped manner from top to bottom, wherein water-distributing water level adjusters are respectively arranged between the surface flow constructed wetland and the first-stage plant pond, and between the first-stage plant pond and the second-stage plant pond; an aquatic plant is planted into the surface flow constructed wetland; and water surface plants and riparian plants are planted into the first-stage plant pond and the second-stage plant pond. The constructed wetland and plant pond joint treatment system runs by completely utilizing an automatic-flow manner, does not generate the operating cost, is simple in management and maintenance, and has high application value.

Description

technical field [0001] The invention belongs to the technical field of ecology and environmental protection, and in particular relates to a combined treatment system of an artificial wetland and a plant pond for advanced treatment of tail water. Background technique [0002] At present, most of the sewage treatment plants are implementing the second-level or first-level B discharge standards in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002). To achieve the first-level A discharge standards, it is generally necessary to increase the depth treatment process, which will greatly increase the cost of sewage treatment. Constructed wetland sewage treatment technology is a composite process combining natural purification and artificial treatment. It mainly uses the action of substrates, plants and microorganisms to purify sewage. It has the advantages of less investment, simple operation, and low maintenance and operation costs. It can not only...
