Abstract

A floating biologic island method for treating the polluted large-area water features that the maturalized plants are planted on the artificial floating islands and the microbes are inoculated to the root system of said plants to absorb, convert and degradate the pollutants in water, such as nutritive substance (N, P, etc), heavy metals, organic substances, etc.

Description

technical field

[0001] The invention relates to water body pollution control technology, in particular to a method for repairing water body of a microbial floating island with membrane-hanging organisms for large-scale water body pollution control. Background technique

[0002] Eutrophication is the most serious pollution problem facing natural water bodies such as lakes, reservoirs, and rivers in my country. According to statistics, the main lakes in my country are eutrophic, accounting for about 60% of the total number of lakes. The continuous aggravation and rapid development of eutrophication will cause the water body to lose its due function, affect the environmental quality, and affect economic construction and social development. Due to the limitations of natural water bodies such as wide areas, large areas, and complex topography, the development of water quality control has been restricted to a large extent. In recent years, my country has invested a lot of manpowe...

Embodiment Construction

[0007] Microbial membrane-hanging biological floating islands mainly use pioneer plants vetiver and chrysanthemum as floating island plants, and according to different regions and different waters, select some soil aquatic plants, such as water onions, cattails, calamus, iris, and parasols Bamboo, big drift, water hyacinth, canna, quince, water grass, water celery and properly domesticated flower plants. Before planting, the floating island plants should be domesticated and cultivated in the breeding base according to the plant habits, so that they can adapt to the growth of the target polluted water body and facilitate the formation of complex microbial films. Experiments have proved that pioneer plants have the strongest ability to absorb nitrogen, phosphorus, and heavy metals among aquatic plants, and are the preferred species for water purification. When the floating island plant seedlings grow to a height of 20cm, move them into the floating island soilless culture medium...
