Embodiment Construction
[0017] The present invention will be further described below in conjunction with embodiment:
[0018] screening of plants
[0019] Through the screening of the present inventors, the influence of factors such as the purification effect, whether the material is easy to obtain, whether the harvest period of the plant is consistent, and the growth of the plant are considered. Determine Canna indica, Thalia dealbata, Scirpus validus and Pontederia cordata as warm-season plants for interplanting; determine German iris (Iris pseudoacorus), rape (Brassicacapestris), water Celery (Oenanthe javanica) and calendula (Calendula officinalis) are interplanted cool-season plants.

The invention relates to an artificial wetland warm season and cold season plants interplanting configuration method in subtropical areas, naturally and alternately growing characteristics of warm season and cold season plants are utilized, warm season plants are harvested firstly when the overground parts of autumn plants are withered and yellow, then cold season plants are interplanted between the plants, the overground parts of the warm season plants are dead when in cold seasons, the clod season plants grow naturally and can be harvested when in late spring, and at the time, the overground parts of the warm season plants have grown. According to the invention, the season changing problem of the plants can be solved, the warm season plants do not need to be changed, the microenvironment conditions nearby the root are not changed, the sewage treating effect can be ensured, the influence of seasons and climates is less, the aspect change of the plant is increased, and the stronger view effect can be achieved.
Description
technical field [0001] The invention relates to a method for interplanting plants in warm and cool seasons in artificial wetlands in subtropical regions, and more specifically to the application of a plant interplanting configuration mode in subtropical regions for domestic sewage purification and underflow artificial wetlands. Background technique [0002] Constructed wetland is a kind of artificially designed and constructed wetland system for sewage treatment. It usually consists of artificial substrate and aquatic plants growing in it. It is a unique water-soil-plant-microbial ecosystem. Its physical, The synergistic effect of chemistry and biology can effectively treat sewage. Compared with traditional activated sludge treatment technology, constructed wetland has the advantages of good pollutant removal effect, strong impact load resistance, low operating cost, and easy maintenance and management. Constructed wetland has been widely used at home and abroad. [0003] m...
