Abstract

Abstract

Using reclaimed water as the supplementary water for rivers and lakes has become an important measure for urban water environment management. But the inflow of reclaimed water also brings the risk of algal bloom outbreak into the water bodies. In order to explain the phenomenon of filamentous algae's algal blooms easily appearing in the recharged water body of reclaimed water, the growth mode and outbreak causes of filamentous algae in a river recharged with reclaimed water in South China was investigated through field investigation and laboratory experiments. It was found that the growth of filamentous algae had four stages:dormancy, germination, expansion and eruption. In the first three stages, they attached to the bottom of the river and continuously spawned filaments into the water. When the filaments accumulated to a certain amount, they broke free from the bottom and then floated up, and then algal bloom happend. Hydrodictyon(spp) was the dominant species in algal bloom in the rivers. Its growth rate and maximum density were much higher than that of the associated specie, Tolypothrix(spp). So it could be called as algal bloom algae. The optimum growth temperature was about 25℃ for Hydrodictyon(spp), but it still could grow at a low temperature of 15℃ though the growth rate was lower. Therefore, filamentous algal bloom in the river might result from their growth at low temperature, the attachment on the bottom and sufficient light reaching the bottom. The following measures were recommended for the algal bloom control:laying gravel layer on the bottom, tending cold resistant submerged vegetation and aquatic animals fed on filamentous algae, as well as monitoring accumulation of filaments and warning at early stage.
- reclaimed water,
- filamentous algal bloom,
- growth pattern,
- low temperature advantage,
- control measures
