Problems solved by technology

Algae toxins have high heat resistance. Heating and boiling can neither destroy the toxins nor remove them; coagulation sedimentation, filtration, and chlorination in the tap water treatment process cannot completely remove them
Some investigations and experiments have shown that low concentrations of algal toxins (120-1400ng / L) were detected in the factory water of three waterworks around a lake in my country. That is to say, algal toxins in water cannot be completely eliminated by conventional drinking water treatment processes

Abstract

The invention provides a water body repairing system and a water body repairing method, wherein the system includes a power supply system, an aerating system, submerged plants, aquatic animals, an artificial medium, an electrolytic tank and a resistor. The power supply system is respectively connected to the aerating system and the electrolytic tank and supplies power to the aerating system and the electrolytic tank. The artificial medium includes a fixing device and an iron-carbon combined carbon fiber medium arranged thereon. The iron-carbon combined carbon fiber medium includes an iron material and carbon fibers suspended thereon and is connected to the aerating system through the resistor. The electrolytic tank is arranged within an aerating range of the aerating system. The submerged plants, the aquatic animals and the artificial medium are dispersed in a water body to be repaired. The water body repairing system can inhibit reproduction of alga, is enhanced in degradation capability on algal toxin and is improved in water body purification performance.

Description

technical field [0001] The invention relates to the technical field of energy and ecological environment restoration, in particular to a water body restoration system and restoration method. Background technique [0002] Human survival and development are inseparable from water resources. Water is the basis for the stability and development of the entire human society, especially drinking water resources that are closely related to human production and life. In recent years, my country's environmental pollution has become increasingly serious, and the ecological environment has been extremely damaged. Not only exogenous pollution has intensified, but endogenous pollution sources have also become an important source of water pollution. Nutritization, reduced dissolved oxygen, blackened and smelly, reduced transparency, death of aquatic organisms, accumulation of a large amount of pollutants to the bottom of the water, causing thickening of the silt layer, etc., resulting in da...
