Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0028] When the particles suspended in water are small enough to a certain extent, the energy of their Brownian motion is enough to prevent the action of gravity, so that the particles do not settle. This suspension can remain stable for a long time. Moreover, the surface of suspended particles is often charged (often negatively charged), and the repulsion of the same charge between particles makes it difficult for the particles to merge and become larger, thereby increasing the stability of the suspension. The flocculants and oxidants can be used alone or in combination.

[0029] Inorganic flocculants can be selected from ferrous sulfate, ferrous chloride, alum, polyaluminum chloride, basic aluminum chloride, aluminum sulfate, calcium chloride, etc.; organic flocculants are mainly polymer flocculants, and...

Abstract

The invention discloses a water quality improvement method in water ecology restoration. The method includes the steps of intermittently using flocculating agents and / or oxidizing agents for water in the process of the restoring water ecology so that suspension of a water body can be coagulated, conducting sedimentation so that the transparency of the water body can be improved, and using flocculating agents and / or oxidizing agents for the water body as well under the condition that the water body is not clear enough or the transparency is smaller than 0.8 meter. By means of the method, the water quality is improved, the water body can reach a certain requirement for transparency, the light compensation condition required for plant growth of middles of plants at the water depth with the 1.5 times of transparency is met, and growth of aquatic plants is facilitated.

Description

technical field [0001] The invention relates to the technical field of water ecosystem construction and restoration engineering, in particular to a method for improving water quality in water ecological restoration. Background technique [0002] At present, some existing lakes have reached the level of severe eutrophication, algae outbreaks have occurred, the transparency of the water body has been lower than 0.5 meters, and they are even in a state of hypoxia at night. It is no longer suitable for the survival of aquatic animals and plants. [0003] During the construction (restoration) of the water ecosystem, especially during the planting of submerged plants, or because of the concentrated entry of surface runoff, the water body is likely to be turbid. The turbid water body seriously reduces the light compensation conditions required for plant growth, seriously affecting the survival of plants and the effect of water quality. [0004] Therefore, it is necessary to impro...
