Novel microorganism floating island and construction method thereof

Abstract

The invention discloses a novel microorganism floating island and a construction method thereof. The novel microorganism floating island comprises a carrying body and microorganism carrying sleeves, the carrying body is fixed to a target area in a tying mode, and a carrying body inner hole is formed in the middle of the carrying body; a plurality of through holes are formed in the bottom of the carrying body inner hole and used for containing the microorganism carrying sleeves; the microorganism carrying sleeves are detachably arranged at the bottom of the carrying body inner hole; a microbialmaterial is arranged in the microorganism carrying sleeves. The novel microorganism floating island is simple in structure, convenient to produce and assemble, easy to maintain and capable of effectively reducing the ecological treatment cost, and particularly has obvious advantages in long-distance riverway treatment. In addition, according to the method, a carrying space is reserved for the microorganism floating island, existing river surface equipment including plants, solar equipment and the like can be compatible, and the function expansibility of the novel microorganism floating islandis improved.

Description

technical field [0001] The invention relates to the technical field of river channel environment treatment, and mainly relates to a novel microbial floating island and a construction method thereof. Background technique [0002] With the development of society and economy, a large amount of urban and rural domestic sewage is discharged into rivers, resulting in severe river pollution, and the problem of black and smelly rivers is common. The direct cause of the black and odorous water body is the excessive content of organic pollutants, nitrogen, phosphorus and other nutrients in the river, and the low supply of dissolved oxygen in the river, resulting in insufficient microbial decomposition ability. [0003] At present, the application of microbial technology is very common in river channel management. Generally, there are two methods of directly adding microbial reagents (powder, liquid) in the river channel. Directly adding microorganisms can be done manually or mechanica...

Problems solved by technology

The direct cause of the black and odorous water body is the excessive content of organic pollutants, nitrogen and phosphorus and other nutrients in the river, and the low supply of dissolved oxygen in the river, resulting in insufficient microbial decomposition ability

[0003] At present, the application of microbial technology is very common in river channel management. Generally, there are two methods of directly adding microbial reagents (powder, liquid) in the river channel. Directly adding microorganisms can be done manually or mechanically, but in some flowing river channels , due to the timeliness of river flow and microbial products, the frequency of microbial dosing is large, which increases labor costs, and the cost of mechanical equipment also gradually increases over longer flow distances

[0004] Chinese Invention Patent Application Publication No. CN205710089U proposes that the microbial culture dish set in the water body can increase the microbial population in the river, but cultivating microorganisms in the field can only form a certain amount of biofilm, which is limited by environmental factors such as the nutritional conditions of the river itself. The content is not enough to meet the needs of black and odorous rivers, and when the water quality of the river improves, the biofilm itself will gradually disappear due to the lack of nutrients
