METHOD FOR COOPERATIVE CONTROL OF MICROCYSTIS AERUGINOSA BY USING CHUB, BIGHEAD, CATFISH AND DAPHNIA |
| 摘要 |
The present disclosure relates to methods for cooperative control of microcystis aeruginosa by using chub, bighead, catfish and daphnia, and belongs to the technical field of water treatment. The microcystis aeruginosa in a water body is controlled using a food chain relationship; the chub, the bighead, the catfish and the daphnia can directly eat the microcystis aeruginosa in a filtering manner; and meanwhile, the chub, the bighead and the catfish also can intake the daphnia, so as to indirectly consume the microcystis aeruginosa in the water body, wherein the fishes, the daphnia and the microcystis aeruginosa form the food chain relationship; in addition, the microcystis aeruginosa at the upper, middle and lower layers and a microcystis aeruginosa hypopus at the bottom layer can be controlled by fully utilizing the vertical spatial distribution difference of the three fishes in the water body. |

1. A method for cooperative control of microcystis aeruginosa using chubs, bigheads, catfishes and daphnia, comprising:
selecting an eutrophication water domain, wherein total nitrogen (TN), total phosphorus (TP) and chlorophyll indexes in the water satisfy the following requirements: about 1.2 mg/L<TN<about 2.7 mg/L, about 0.05 mg/L<TP<about 0.1 mg/L, about 11 mg/m3<chlorophyll<about 78 mg/m3, and a maximum depth does not exceed about 3 meters, and a flow rate of a water flow is about 0˜0.1 m/s; and putting the chubs, the bigheads, the catfishes and the daphnia according to a volume of a water body, wherein a density of the chubs is about 60˜300 g/m3, a density of the bigheads is about 20˜80 g/m3, a density of the catfishes is about 40˜160 g/m3, a density of the daphnia is about 30˜50 daphnia/L, wherein the daphnia eats the microcystis aeruginosa, and the chub, the bighead and the catfish then eat the daphnia and the microcystis aeruginosa. |
