Abstract

The invention relates to a treatment device for a eutrophic water body, in particular to a combined bio-floating bed. The bio-floating bed comprises a bed body which is formed by connecting a plurality of floating bed single bodies and an aeration cavity in the bed body, wherein an aeration device is arranged in the aeration cavity. According to the combined bio-floating bed, a minitype aquatic ecosystem is built through increasing dissolved oxygen in the water body, introducing aquatic plants and increasing population and quantity of microorganism, nitrogen and phosphorus nutrients in the eutrophic water body in an urban landscape can be stably and effectively removed, and a new process is provided for water quality preservation in the northern urban landscape water body which takes tail water of an urban sewage treatment plant as the main nourishment source.

Description

technical field [0001] The invention relates to a device for treating eutrophic water body, in particular to a biological floating bed. Background technique [0002] With the continuous development of society and the continuous improvement of people's living conditions, landscape water has been integrated into people's lives, and the construction of water landscape-themed communities, gardens, towns, etc. has developed rapidly. Due to the scarcity of water resources in the northern region, most urban landscape water bodies use the tail water of urban sewage treatment plants as the supply water source. The tail water of sewage treatment plants has high content of nutrients such as nitrogen and phosphorus. In addition, most of the urban landscape water bodies are closed and slow-flowing water bodies with static or poor fluidity. As a result, the water quality is prone to black odor and eutrophication, which seriously affects the surrounding urban landscape and residents. livi...
