Abstract

The invention relates to the technical field of self purification of riverways, in particular to an ecological system for improving the self purification capacity of a riverway and a construction method of the ecological system. The system comprises the riverway, side slopes arranged on the two sides of the riverway and infiltration dams arranged on the riverway at intervals, wherein a stone purification layer is arranged on the surface layer of the river bottom of the riverway. A soil layer is further arranged on the stone purification layer. Water is arranged on the soil layer. An aquatic plant community layer is arranged on the surface layer of the water. Ecological bags are arranged on the side slopes. A vegetation layer is arranged on the surface of each ecological bag. The complete riverway ecological system is constructed in a staging manner through a chemical method, a biological method and an ecological method according to different water quality conditions; the water qualityis purified, and meanwhile the self purification capacity of the water is improved; the original ecological system of the water is restored; no secondary pollution is generated; and it is guaranteed that the repaired riverway ecological system operates stably for a long time.

Description

Technical field

[0001] The present invention relates to the technical field of self-purification of river channels, in particular to an ecological system for improving the self-purification ability of river channels and a construction method thereof. Background technique

[0002] The rapid economic development, rapid population growth, acceleration of urbanization, and the intensive development of agriculture and industry have resulted in an increasing demand for water. At the same time, more and more sewage and wastewater flow into natural water bodies, which in turn causes water bodies. Pollution is becoming more serious, and the self-purification ability of water bodies is gradually decreasing. At the same time, the resilience and resistance of river ecosystems are also worrying, which seriously affects the structure and function of river ecosystems. With the strengthening of human activities, the morphological structure of the river channel has also undergone earth-shaking ch...
