Abstract

The invention relates to a method for purifying the polluted water body of an urban riverway, in particular to a method for circularly purifying the polluted water body of an urban riverway ashore. The polluted water body of the urban riverway is circulated ashore by a water pump, and the sewage of the riverway is purified by units in a plant-growing filtering tank arranged on the river bank, such as a plant root layer and a substrate-adsorbing filtering layer, and then follows back into the riverway. The invention realizes plant root layer-absorbing purification and substrate filtering layer-adsorbing purification for removing the pollutants of the water body, effectively combines plant remediation and physical remediation techniques together, and is integrated with the landscape of the greenbelt of the river bank, meanwhile, the invention solves the problem on how to supply water for the daily maintenance of the plant of the greenbelt, and can be combined with the cement bank protection work, and the technique is simple and effective.

Description

technical field [0001] The invention belongs to a method for purifying polluted water, in particular to a method for circulating and purifying urban river polluted water ashore. Background technique [0002] After the 1950s, the global population grew rapidly and industry developed rapidly. The situation of global water resources is rapidly deteriorating, and the "water crisis" is becoming more and more serious. Especially for the rivers flowing through cities and towns, they are subject to the disorderly discharge of urban industrial sewage, agricultural pollutants and domestic sewage, which makes the water environment pollution of the river basin more and more serious. As a result, the water flow pattern and the basin habitat have been out of balance for a long time, and the ecological health of the river has been seriously damaged. Especially in China, the per capita share of water resources is small, the spatial distribution is unbalanced, and with the acceleration of ...
