Method for lake purification and water ecological environmental renovation

Abstract

The invention relates to a method for lake purification and water ecological environmental renovation, comprising: a rope contact oxidation step, a pressurizing floating step, a waterweed cultivation island use step, and a lake pollution state analysis step, while an optimal use of a step is selected, whether comprehensively using the steps is selected: a rope contact oxidation selection step selecting objects needed to be treated and an operation method in the rope contact oxidation step; the method uses a rope contact oxidation device clears away pollutants in a lake or flowing from the outside of the lake to the inside of the lake, particularly organic matters and solid subjects (SS), uses a pressurizing floating method to clears away sediment and algae deposited at the bottom of the lake, uses the waterweed cultivation island use method to clear away nutrients and organic matters in the lake, and provides algae proliferation inhibition and places for fish oviposition and hiding, thereby renovating water ecological environment.

Description

technical field [0001] The present invention relates to a method for purifying lakes and restoring the water ecological environment, and in more detail to a method for controlling polluting substances in lakes and restoring the water ecological environment in lakes. Pollutants that flow into the lake from outside the lake, especially organic matter and solid matter (SS), use the pressurized flotation method to remove sediment and algae deposited on the bottom of the lake, and use the aquatic plant cultivation island method to remove nutrients and organic matter in the lake , and provide algae proliferation inhibition and fish spawning and hiding places, thereby restoring the water ecological environment. Background technique [0002] In urban areas, it is used to improve the appearance of the city and as a water source, and there are many lakes nearby. Such lakes have the function of creating a water ecological environment, so they are used as a resting space for people and...

AI Technical Summary

Problems solved by technology

So far, the previous lake purification methods only focus on the removal of temporary pollutants in the lake, without considering the effective purification of various pollution sources and pollutants, the restoration of water ecology, and the creation of an ecological environment.
