Multi-stage water quality eco-purification system suitable for shallow narrow mixed water river channel

Abstract

The invention relates to a multi-stage water quality eco-purification system suitable for a shallow narrow mixed water river channel, which can effectively solve the problems of multi-stage water quality eco-purification and eco-remediation of the shallow narrow mixed water river channel. The system adopts a method comprising the following steps: arranging an overflow dam formed by building rocks in a main river channel; arranging a biological solid settling pool in front of the overflow dam, arranging a semi-submersible artificial ecologic filter bed and an in-situ remediation module combination unit behind the overflow dam and in a sheer river bed, arranging an ecologic floating bed and an ecologic foundation in the in-situ remediation module combination unit in sequence to form a multi-stage eco-purification unit, arranging and fixing a plurality of multi-stage eco-purification units in the river channel along the river channel to form the multi-stage water quality eco-purification system. The ecologic foundation can adsorb pollutants in water, and provides a dwelling site for microbes; the microbes dwelling on the ecologic foundation can further remove pollutants in water. The system is scientific and reasonable, is suitable for intensifying and purifying ecological engineering of the shallow narrow mixed water river channel, and has an important meaning in river pollution prevention and ecologic remediation.

Description

technical field [0001] The invention relates to river prevention and control, in particular to a multi-stage water quality ecological purification system suitable for shallow and narrow mixed water channels. Background technique [0002] Rivers include river water bodies, river beds, and river banks (dykes), and have multiple functions such as flood regulation, pollution purification, climate regulation, and environmental beautification. Over the years, human activities have destroyed the natural form and aquatic habitat of the river system, resulting in the decline of the self-purification capacity of the river, the increase of water pollution, and the decline of biodiversity. For a long time, experts and scholars have accumulated a lot of practical experience in river water purification and ecological restoration technologies. At present, the water quality purification and ecological restoration technologies of polluted rivers are mainly divided into three categories: phy...
