Problems solved by technology

However, these methods have certain limitations and deficiencies: they are mainly aimed at black and odorous water bodies containing industrial wastewater, and their application range is narrow; the application of biological filter technology in rivers is not convenient for controlling the influent flow rate, backwashing and other operations, which hinders the operation of rivers. Flood function; simple aeration and oxygenation in the river channel, the

Abstract

The invention discloses a solar aeration-plant bed supported device with a biological membrane. The device is characterized in that a solar cell, a supporting connecting device, an air pump, an aeration pipe and an air distribution pipe are combined to form an aeration system, a strong buoyancy carrier and an emergent aquatic plant form an ecological floating bed system; a filler system provides a place for lots of microbial floras, phytoplanktons, protozoa and micro-metazoons to attach and live; all the systems are co-built to form a biological membrane capable of effectively and quickly purifying contaminants. The solar aeration-plant bed supported device with the biological membrane is capable of effectively removing organic matters and other pollutants such as COD (Chemical Oxygen Demand), nitrogen and phosphorus in water, purifying water, improving the ecological system of the river, helping recovering the self-cleaning ability of water and also achieving certain environment beautifying effect.

Description

technical field [0001] The invention relates to urban river water pollution control and environmental restoration methods, in particular to a device for river water ecological restoration and water quality maintenance. Background technique [0002] As an important carrier of resources and environment, urban rivers are related to the survival of the city, restrict the development of the city, and are the source of life of the city. Urban rivers can improve the ecological environment of the city, adjust the climate, shape the urban landscape, provide residents with a better living space, promote investment, promote the vigorous development of related industries, and drive the overall progress of the city. It can be seen that urban rivers play a very important role in the development, construction and ecological environment of cities. However, with the development of the economy and society, the pollution of urban rivers is gradually increasing, and due to long-term neglect of...
