Method of constructing ecological revetment for intensively intercepting and clearing non-point pollution based on organisms

Abstract

The invention relates to a method of constructing an ecological revetment for intensively intercepting and clearing non-point pollution based on organisms, which comprises the steps of investigating hydrologic conditions of a river, determining non-point pollution load and hydraulic retention time of a riparian zone in a unit length, analyzing characteristics of the non-point pollution along the river, screening a high-efficiency bacterium which can efficiently remove the non-point pollution or constructing gene engineering bacteria capable of removing nondegradable organic pollutants, constructing hollow hexahedral ecological revetment members, and growing plants in the members, thereby constructing the ecological revetment. Compared with the prior art, with the adoption of the method, the non-point pollution, particularly the nondegradable organic pollutants, can be removed effectively, the river pollution load can be decreased, potential ecological risks of the non-point pollution to a river ecosystem are reduced, and local raw materials are utilized to improve the environmental compatibility of the members, so that good habitat conditions are provided for the growth of microbial communities and vegetations at the riparian zone, and the mechanical stability of the riparian zone is improved.

Description

technical field [0001] The invention relates to the technical field of resource and environment protection, in particular to a method for constructing an ecological slope protection based on bio-enhanced interception and removal of non-point source pollution. Background technique [0002] The riparian zone is a semi-terrestrial ecosystem between the river and the land. It is directly or indirectly affected by the change of the river water level and has a buffer effect. It usually connects the above-ground terrestrial system and the terrestrial system through the hydrological process of surface runoff and subsurface flow. aquatic system. The area ratio of the riparian zone is not high in the watershed ecosystem, but it plays an irreplaceable role in the process of water and nutrients flowing into the river. It intercepts non-point source pollution, builds river habitats, and promotes the connectivity between the river and its surrounding environment. There's important meanin...

AI Technical Summary

Problems solved by technology

The reduction efficiency of non-point source pollution in the riparian zone mainly depends on the characteristics of the surface matrix of the riparian zone. The current ecological slope protection matrix materials have a low ability to remove non-point source pollution, especially refractory organic pollutants (such as POPs, PCBs, etc.). There are potential risks in the riparian micro-ecosystem
