Abstract

The controllable fast reservoir blue-green alga bloom eliminating method includes: raising filter feeder fishes; raising and protecting snails, crabs, calms and other water benthic fauna to degrade excrement of the fishes; and controlling water level to favor the disturbance of wind wave to bottom sludge, to ensure the ingestion of water benthic fauna to silt and the limitation of snails' ingestion area. The present invention adopts biological treatment of reservoir blue-green alga bloom without lowering eutrophic salt condition of water.

Description

technical field

[0001] The invention relates to the technical field of eliminating algae blooms, in particular to the technology for eliminating cyanobacteria blooms in reservoirs. Background technique

[0002] Utilizing ecological management technology to control cyanobacterial blooms caused by eutrophication of water bodies is a fact that everyone has unanimously recognized at present. For this reason, two areas for the control of algae blooms in water bodies have been derived. 1. Non-classical biological manipulation technology to control algae blooms such as Microcystis and Anabaena, 2. Bioremediation technology to reduce eutrophic salt (nitrogen, phosphorus) components in water.

[0003] Existing control technical problems: The biomanipulation technology of filter-feeding fish has been widely used, there are successful cases, and there are also lessons from failures, among which two recognized facts: (1) filter-feeding fish (carp, silver carp) can Reduce the number of ...
