Ecologically active water bank of a river and its manufacturing method

Abstract

The invention relates to an ecological active water bank for rivers and a manufacturing method thereof and belongs to the technical field of control of water pollution. The ecological active water bank comprises an impermeable layer, ecological active medium layers, a sewage distribution pipe, a microorganism feeding pipe, an isolating membrane, a non-woven fabric isolating layer, an ecological concrete protecting layer, a vegetation layer and a microorganism bed. The manufacturing method comprises the steps of constructing a water diversion building, clearing a water bank foundation, laying the impermeable layer and a lower ecological active medium layer, distributing the sewage distribution pipe, laying an upper ecological active medium layer, constructing the ecological concrete protecting layer, and culturing microorganisms in the ecological active medium layers. The nature-simulating artificial water tank with relatively strong ecological activity is constructed, has purification functions of isolating, absorbing, decomposing and settling water body pollutants in polluted rivers and simultaneously has the functions of improving spatial heterogeneity of the water bank, increasing the biomass of the water bank and restoring a natural ecological water bank.

Description

technical field [0001] The invention belongs to the technical field of water pollution control engineering, and in particular relates to a river ecologically active water bank and a manufacturing method thereof. Background technique [0002] River water pollution is a global concern. In addition to the water quality pollution of rivers and lakes caused by man-made discharge of pollutants, one of the important reasons is the relative reduction in material exchange, degradation, transformation, and utilization of pollutants between water-shore (including water-river bottom and lake bottom), which is mainly manifested on the waterfront. The ability to reduce pollutants in water (including the river bottom) can no longer match the increasing pollution load of rivers and lakes. At present, to solve the problem of water pollution in rivers and lakes, measures such as implementing sewage interception, establishing sewage treatment plants, regularly injecting biochemical agents, tr...

AI Technical Summary

Problems solved by technology

Due to the continuous increase of pollutant discharge intensity caused by economic and social development, the load of pollutants entering the river is greater than the ecological purification capacity of the waterfront, and the ecological activity and water purification ability of the waterfront are relatively reduced; at the same time, due to improper intervention on the riverbank (such as construction Closed hardened water bank, revetment, etc.), will also lead to the loss of ecological activity of the water bank and the ability to purify water quality
