Abstract

The invention relates to an ecological remediation system and method for black and odorous water. The ecological remediation system comprises an artificial ecological floating bed which may float on water; various aquatic plants are fixed the ecological floating bed; a carbon fiber filler is hung below the ecological floating bed, and an aerating pipe at the bottom of the black and odorous water is arranged below the ecological floating bed; one end of the aerating pipe is connected with a micro-nano bubble generator. The ecological remediation system for black and odorous water is simple in structure, convenient to use and maintain and low in energy consumption, allows dissolved oxygen and redox level in the water to be quickly increased, can purify organic pollutants in the water throughthe synergy of aquatic plants and microbes in the filler, and can provide a shelter, a food site and other resting place for various aquatic animals; therefore, diversity of aquatics is improved, self-cleaning capacity of water can be enhanced, water transparency is improved, and water odor is eliminated.

Description

technical field [0001] The invention relates to an ecological restoration system and method for black and odorous water bodies, belonging to the technical field of ecological restoration. Background technique [0002] With the acceleration of urban development and the rapid growth of population, a large number of pollutants are produced and discharged into rivers and lakes, causing water environment pollution. Black and odorous water body is an extreme phenomenon of organic pollution in water body. From the perspective of the formation mechanism of black and odorous water, it is mainly the result of a series of physical, chemical and biological actions of organic pollutants in the water under anoxic or anaerobic conditions. The dissolved oxygen in the water is significantly reduced, resulting in black and smelly water. Studies have shown that when DO < 2.0mg·L-1 in the water body, it means that the river is in a black and odorous state. As urban and rural residents dema...
