Description

Technical Field

[0001] The utility model relates to the technical field of water pollution prevention and control, and more specifically, to a microbial generator for controlling eutrophication of open water bodies. Background Art

[0002] At present, the treatment processes for open water bodies mainly include: physical methods, chemical methods, and ecological-biological methods.

[0003] Physical methods and chemical methods are not sustainable, cannot improve the water environment capacity of river channels, and chemical methods are prone to cause secondary pollution. The river channel aeration method in ecological-biological methods aims to provide dissolved oxygen for microorganisms and is suitable for the treatment of urban landscape river channels and slightly polluted water sources. For severely polluted open water bodies, other ecological measures need to be combined, and the effect is poor when used alone. The aquatic plant purification method has a certain effect on slightly polluted water bodies, but the aquatic plants need to be harvested regularly, the daily maintenance cost is high, and it affects flood discharge to a certain extent. Conventional bioremediation technologies degrade pollutants in water by adding microbial agents, but they need to be added regularly, and the addition cost is high.

[0004] Therefore, we have designed a microbial generator for controlling eutrophication of open water bodies, which can continuously and stably release special microbial agents into the water body, increase the amount of microorganisms in the river channel, thereby effectively improving the self-purification ability of the regional water body, improving the water quality of the treated water body, reducing the project investment, and reducing the later maintenance and management costs.
