Method for repairing eutrophication water by utilizing aquatic plants and microorganisms together

Abstract

The invention provides a method for repairing eutrophication water by utilizing aquatic plants and microorganisms together. The method specifically comprises the following steps: a, river channel cleaning: removing various floating foreign matters on water surface through manual salvaging, and reserving volunteer plants of the water; b, aquatic plant-microorganism combined purification sections: adopting a stereoscopic structure of an aquatic plant floating bed, reasonably distributing in the water, and forming a zonal plant net wall having certain width and traversing a river channel; c, aerobic microorganism repairing sections: utilizing microbial flora, distributing in downstream water zones of the aquatic plant-microorganism combined purification sections after domestication, moderately aerating, and increasing the dissolved oxygen in the water of the river channel; d, sequentially distributing the aquatic plant-microorganism combined purification sections and the aerobic microorganism repairing sections along the river channel in a reciprocating and serial connection way, and forming a purification system of continuous batches. According to the method provided by the invention, the self cleaning capacity of the water can be improved while the water quality is purified to the maximum, the effect of beautifying the water is also integrated, secondary pollution cannot be generated, and the characteristics of environment protection, energy conservation and reclamation are integrated.

Description

technical field [0001] The invention relates to the technical field of restoration and treatment of eutrophication in river channels, in particular to a method for jointly repairing eutrophic water bodies by utilizing aquatic plants and microorganisms. Background technique [0002] Eutrophication of water body means that a large amount of inorganic nutrients such as nitrogen and phosphorus enter rivers, lakes, bays and other water bodies with relatively slow water flow, causing algae and other aquatic plants to multiply, the dissolved oxygen in the water body decreases, the water quality deteriorates, and other aquatic organisms die in large numbers. Phenomenon. With the rapid development of social industrialization, the unreasonable use of nitrogen and phosphorus fertilizers in agricultural production, the random stacking of untreated livestock and poultry manure, the extensive use of phosphorus-containing detergents in daily life, the arbitrary discharge of domestic sewage...

AI Technical Summary

Problems solved by technology

[0005] However, due to the complex hydrology and water quality in various places, the existing single aquatic plant floating bed or microbial restoration technology is difficult to achieve the expected biological treatment effect in the actual use of river sewage treatment, and the cost is high
