Description
Technical Field
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
With the development of social economy, a large amount of domestic sewage in cities and countryside is discharged into rivers, so that the current situation of river pollution is severe, and the problem of black and odorous river channels is generally seen. The direct cause of the black and odorous water body is that the content of organic pollutants, nitrogen, phosphorus and other nutrient elements in the river channel is too high, and the dissolved oxygen supply in the river channel is too low, so that the microbial decomposition capacity is insufficient.
In the current river course treatment, the application of microbial technology is common, two methods of directly adding microbial agents (powder and liquid) into a river course are generally adopted, the microorganism can be directly added manually or mechanically, but in some flowing river courses, due to river flow and timeliness of microbial products, the microorganism adding frequency is high, the labor cost is increased, and the cost of mechanical equipment is gradually increased in a longer flowing distance.
The Chinese patent application publication No. CN205710089U proposes that a microorganism culture dish arranged in a water body increases the microorganism population in a river, but the microorganism culture under the field condition can only form a certain amount of biomembrane, which is limited by the environmental factors such as the nutrient condition of the river, the microorganism content of the biomembrane is not enough to meet the requirement of the black and odorous river, and the biomembrane disappears gradually due to the lack of nutrient substances after the water quality of the river is improved. The microorganism is used for treating or controlling the river water quality, and enough microorganism biomass must be ensured, so that the effect of external microorganism investment is more obvious.
In recent years, many studies have been made on immobilized microorganisms, and for example, chinese patent application publication No. CN106520752A discloses a method for preparing biochar-immobilized microorganisms by a cross-linking method; CN106542652A also discloses a method for preparing immobilized microorganisms by using a diatomite adsorption method. The existing immobilized microorganism preparation method is mature and stable, the immobilized microorganism can be used for realizing the continuous addition of the microorganism (gradual dissolution and release or solute exchange and release in water), the maintenance cost is reduced, and the microorganism can be used more conveniently by an immobilization technology. The slow release technology developed in other industries such as pesticide and fertilizer, pharmaceutical industry and the like can also be applied to water area treatment.
