The invention discloses a method for removing alga and other pollutants in eutrophia rivers and lakes, relates to the technical field of natural water body purification, and solves the problem that secondary pollution is generated due to the failure of degrading products of metabolism generated after the filter feeding of alga is conducted by shellfish. The method comprises the steps that S1, suspending body skeletons which are constructed by sealed plastic pipelines are annularly connected to form a suspending body skeleton body of a device using the sealed plastic pipelines, mesh structuresbraided by plastic ropes are the mesh structures braided on the suspending body skeletons constructed by the sealed plastic pipelines, and aquatic plants are arranged on the upper portion of the meshstructures braided by the plastic ropes; S2, plastic net bags are hung on the mesh structures braided by the plastic ropes at certain intervals, and filter-feeding aquatic creatures of aquatic filter-feeding shellfish and the like which are cultured through hanging are placed in the plastic net bags; S3, suspending type soft or semi-soft creature filler carriers are suspended on a suspended type bionic water weed filler carriers, and the length of a hanging rope is adjusted.
Description
technical field [0001] The invention relates to the field of natural water body purification, in particular to a method for removing algae and other pollutants in eutrophic rivers and lakes. Background technique [0002] The most basic connection between the components in the ecosystem is realized through the food chain (ie, nutritional relationship), and the energy flow and material cycle in the ecosystem are also carried out along the food chain. The longer the food chain in the ecosystem, the greater the energy consumption and the better the purification effect. In order to improve the ecological effect and ecological purification function, in order to achieve the purpose of efficiently removing pollutants and realizing the purpose of recycling pollutants, a kind of "additional ring" ecological engineering came into being. The realization of this technology is mainly to strengthen or replace the natural biological population by selecting some artificial biological popula...
