Application of bulrush as algae inhibiting material

Abstract

The present invention belongs to the field of water treating technology, and discloses the application of reed as algae inhibiting material. Reed as algae inhibiting material may be used through extracting algae inhibiting matter from reed with water or organic solvent and applying the extracted matter to the water to be treated; or setting bundled reed or reed in nylon bag into water to be treated. Utilizing reed as algae inhibiting material has the advantages of high algae inhibiting effect, low cost, easy control and high ecological safety. The present invention may be used in algae inhibition in natural or artificial water, such as lake, reservoir, river, park water, fish pond, etc.

Description

technical field

[0001] The invention belongs to the field of water treatment, in particular to a new method for controlling harmful algae in natural water bodies. Background technique

[0002] Eutrophication of water body is the main reason for the deterioration of water environment. The eutrophication of the water body leads to the growth of algae, which makes the water body lose its functions such as industrial and agricultural utilization, landscape, and breeding. Existing anti-algae technology mainly utilizes copper ion (Cu 2+ ) herbicides to kill algae. However, copper ions cannot be degraded in water bodies, and will be transmitted in the ecosystem through the food chain, and the higher the trophic level, the higher the concentration of copper ions in organisms (biomagnification). If people eat aquatic animals rich in copper ions, it will endanger human health. Herbicides will kill other higher plants in the aquatic ecosystem while killing algae, destroying the aqu...
