Embodiment 1

[0017] figure 1 Among them, a family courtyard landscape wetland in a Kunming city (like spring all year round), consists of (1) landscape plants (I) (length x width x height: 2000mm x 800mm x 800mm), filtration + nitrifying bacteria pool (II) (L×W×H: 800mm×800mm×800mm), (2) Activated carbon + charcoal plant filter (III) (L×W×H: 800mm×800mm×700mm), (3) Aquatic plant sedimentation tank (IV ) (length × width × height: 800mm × 800mm × 600mm), (4) Aquatic animal breeding pond composition (V) (length × width × height: 2000mm × 1200mm × 500mm). The materials used are: local soil, nitrifying bacteria, activated carbon, carbon residue, nitrifying bacteria sponge, filter cotton, fish, and aquatic plants.

[0018] Its function is:

[0019] (1) add in the pond with local soil (fill soil from pond mouth 100mm), plant ax orchid, pandan grass etc.;

[0020] (II) Nitrifying bacteria sponge + filter cotton to convert nitrate into nitrite. Be careful not to wash the nitrifying bacteria spon...

Embodiment 2

[0026] The landscape wetland in the Chengjiang River Basin on the Yunnan Plateau, the demonstration area length x width x height: 200m x 30m x (0.4-1.5)m, in order to meet the flood discharge, there are 3 outlets connected to the Chengjiang River, the landscape wetland is along the original The river bank extends to the lake, and the wall is made of sandstone and cement. Using the sandstone and slope terrain on the bank, local soil is used 20 meters away from the bank, and the depth of sandstone is about 0.4-1.2 meters. Lotus root, reed, etc. are planted; The depth of 10 meters is about 1.2-1.5 meters, and the structure of backfilling soil woven bags is used in the middle of double rows of wooden piles. Set up non-woven fabrics and anti-seepage films on the inside of the wooden pile frame, and plant calamus, reed flute, windmill grass, wild rice grass, iris, etc. on it, and arrange them in a diagonally symmetrical manner, so that the entire landscape is orderly. , the landscap...

Abstract

The invention relates to a courtyard-style landscape wetland, which consists of a nitrobacteria pond, a plant filtering bond, an aquatic plant settling pond, a conversion pond and an aquatic animal or fish pond. The wetland is mainly applied to the design of urban landscape water areas, the eutrophication control of the landscape water areas and an ecological purified circulating system of the purification of the front of inlets of various cities, parks, river banks or lake banks, families, parks and hotels. The sewage can be purified by the actions of precipitation, adsorption, nitration, denitrification and the like, thus the pollution load is reduced.

Description

technical field [0001] The invention relates to a courtyard-style landscape wetland, which has the effect of purifying the ecological circulation of the courtyard-style landscape wetland along lakes or river banks, hotels, tea bars, coffee houses, families and other aquatic animal viewing systems. Background technique [0002] In recent years, with the development of tourism and the continuous improvement of people's living standards, beautiful lakes and river banks are the first choice for people to relax and take vacations. Courtyard landscapes such as hotels, tea bars, coffee houses, and families have also become people's favorite places. The first choice for choosing a resting place. However, due to non-point source pollution such as agricultural surface runoff and rural domestic sewage, domestic garbage, livestock manure, and breeding wastewater, the beautiful lakes and river banks have lost their natural and fresh aesthetic feeling; and these non-point source pollution...
