Green ecological floating island device

Abstract

The invention relates to a green ecological floating island device. The green ecological floating island device comprises a floating island body and water carts at two opposite sides of the floating island body, wherein each floating carrier comprises a floating basket made of activated carbon, the floating basket is depressed downwards from the top to form a planting cavity, a plurality of pores which are used for communicating the planting cavity with exterior are formed in the wall of the planting cavity, a hollow cavity is formed in the floating basket, the hollow cavity is arranged at the outer side of the planting cavity and communicated with the planting cavity, and a bio-cord is arranged in the hollow cavity. The activated carbon floating basket can plant aquatic plants and absorb and remove water pollutants, the rich pores of the activated carbon floating basket can be used as an inhabit and multiplying carrier of microorganisms, the bio-cord not only can be used as a carrier for the growth of microorganisms and for preventing the loss of the microorganisms, but also can promote the microorganisms to be gathered onto the surface of an aquatic plant root area, and the water carts disturb the water to increase the dissolved oxygen in the water so as to improve the growth environment of the aquatic plants, animals and microorganisms, so that the microorganism biofilm formation rate of the whole floating island body is increased, and the water purification effect is improved.

Description

technical field [0001] The invention relates to the fields of water ecological environment engineering and water pollution control, in particular to a green ecological floating island device. Background technique [0002] In recent years, the level of urbanization and industrialization in my country has been increasing day by day, followed by a significant increase in urban population, resulting in a large discharge of municipal sewage and domestic sewage. When the sewage discharge rate is greater than the natural water purification rate and the urban sewage treatment facilities are not perfect, it will cause The water pollution of the river channel will destroy the water ecological balance, thus seriously affecting the ecological function of the urban river channel and the cleanliness and beauty of the city appearance. [0003] In order to make reasonable use of limited water resources and reduce the discharge of water pollutants, some cities use the secondary treatment of s...

Problems solved by technology

In order to play its value more reasonably and effectively, new ecological floating island devices are constantly emerging. For example, the Chinese invention patent (publication number CN 104211183 A) discloses an ecological floating bed combined with immobilized microorganisms, and plants aquatic purification plants in planting baskets. , the root system of aquatic purification plants extends below the water surface, and the immobilized microbial particles are connected in series with wires and suspended under the main floating plate, using the decomposition and transformation of pollutants by microorganisms to achieve in-depth treatment of water bodies, but after long-term use, microorganisms Particles are easy to lose, and the film-hanging rate of microbial particles on plant roots is low; another example is the Chinese invention patent (publication number CN 104261566 A) which discloses a micro-aeration enhanced ecological floating bed sewage treatment device, which is connected to the bottom of a conventional ecological floating island. The micro-aeration system aerates and oxygenates the device to ensure the aerobic environment of the water body, thereby promoting the growth of microorganisms on the plant root system and the combined filler layer, and maintaining the synergy between the microbial system and the aquatic plant system, but the micro-aeration system has energy consumption Large, not environmentally friendly and other issues
