Problems solved by technology

[0009] Due to the large changes in water level on the bank of the ditch river, the severe alternation of dryness and wetness, and the small drop in water flow, the bank of the ditch river cannot meet the requirements of the above three wetland treatment methods.
At the same time, the above three wetland treatment methods are usually built in the catchment areas of ditches and rivers, all occupying a large area of ​​land

Embodiment Construction

[0023] The implementation process consists of seven links: the screening of basic tool species, the large-scale expansion of tool species, the construction of compound riverbeds, the construction of slope-bank subsurface flow infiltration systems, the construction of slope-bank surface flow systems, the construction of embankment vegetation and aquatic vegetation systems, and post-management. The specific content includes:

[0024] 1. Screening of basic tool species: collecting the list of indigenous species and their bioecological parameters, delineating the optimum ecological range of indigenous species, conducting tests on pollution resistance and decontamination capabilities, and studying their fecundity, growth and utilization value, etc.; Targeted screening was used to identify essential tool species as wetland treatment systems.

[0025] 2. Large-scale propagation of tool species: use basic tool species as raw materials, conduct large-scale cultivation and propagation t...

Abstract

The invention belongs to ecological condition project and hydraulic engineering technology field. It is based on indigene species, keeps the principle of 'from nature, excelled nature' to carry on ecology design, the designed groove, canal, river, bank, constructed swamped land, waste water processing system, and has merits of waste water process, greening and bank protection, beatifying landscape and continuous resources. Through constructing nature simulating ecological system, it can display the waste eliminating function of constructed swamped land system fully, but also it can upgrades material producing ability, and the cost is low, easy to be operated, the area is small.

Description

1. Technical field: [0001] The invention belongs to the technical fields of ecological environment protection engineering and water conservancy engineering. 2. Background technology [0002] At present, three methods are used in the treatment of non-point source pollution of rural and urban wastewater at home and abroad: surface flow wetland treatment method, subsurface flow wetland treatment method and vertical flow wetland treatment method. [0003] 1. Surface wet land treatment method [0004] Wet plants are directly planted on the soil surface, and the waste water flows on the soil surface. Through the flow control of the water inlet and outlet, the surface water level and the residence time of waste water in the system are adjusted. Water infiltrates into the rhizosphere of plants, degrades and purifies waste water through the activities of microorganisms and animals in the rhizosphere and the functions of plant absorption, transformation and storage. Although the co...
