Embodiment Construction

[0039] This embodiment is a biological enzyme carrier for riverbed water ecological restoration, such as figure 1 As shown, the structure of the biological enzyme carrier 3 uses a high-molecular polymer fiber resin material as the network skeleton 1. In order to increase the specific surface area of ​​the biological carrier, the nano-filament carrier 2 is bound on the network skeleton 1. The biological enzyme extracted from the organism is artificially immobilized on the nano-filament carrier 2, and the free biological enzyme is blocked on the nano-filament carrier 2 or restricted to a certain area on the nano-filament carrier 2. It is an active, unique catalyst and a technology that can be used for a long time. Compared with the free enzyme, the immobilized enzyme has the advantages of high stability, easy control, repeated use, and low cost. The high molecular polymer resin material selected in this embodiment is used as a biological enzyme carrier, and has the characteristic...

Abstract

The invention provides a biological enzyme carrier for ecological remediation of riverbed water and a laying method. The carrier comprises a biological enzyme carrier carrying a biological enzyme. Thebiological enzyme carrier comprises a net-shaped framework of a high molecular polymer fiber resin material, and a nano-wire-shaped carrier which is bundled on the net-shaped framework and is used for bearing the biological enzyme, wherein the biological enzyme carrier is supported through a first crushed stone layer laid on a riverbed; a second crushed stone layer is also laid on the biologicalenzyme carrier by sections. The invention discloses the specific laying method of the carrier. A biological enzyme carrier device provided by the invention has the characteristics of simplicity in installation, strong operability, capable of realizing modularized implementation and the like; the laying method of the crushed stone layers increases the roughness of the riverbed and a crushed stone gap provides a living space for benthonic animals and microorganisms; the stability of an ecological system is easy to maintain and the biological enzyme carrier is applicable to rain source type riveswith large riverbed slopes and rapid water flow speeds.

Description

Technical field [0001] The invention relates to the technical field of environmental treatment and water ecological restoration, and particularly relates to a biological enzyme carrier used for riverbed water ecological restoration and a laying method. Background technique [0002] Riverbed ecological restoration mainly includes sediment pollution control and ecological system environment construction. Sediment pollution and sediment resuspension are one of the important reasons for the formation of urban black and smelly rivers. Sediment, as an important endogenous pollutant in urban river water bodies, causes sedimentation of sediments under the influence of hydraulic erosion, human disturbance and biological activities. Re-suspension, and then under a series of physical-chemical-biological effects, the pollutants adsorbed on the sediment particles exchange with the pore water, thereby releasing pollutants to the water body, and a large number of suspended particles float in th...
