Ecological engineering technology for stopping riverway coastal pollutants from entering rivers and restoring vegetation communities

Abstract

The invention relates to an ecological engineering technology for stopping riverway coastal pollutants from entering rivers and restoring vegetation communities. The ecological engineering technology consists of four basic unit systems, namely a land pollutant stopping and purification system, a slope protection system, a base construction system and a plant cultivation system; the units consist of physical materials and plants, wherein the pollutant stopping and purification system is built by materials such as plastic, woods, gravels, plants and the like; the slope protection system is built by materials such as woods or concrete, stone blocks, metal wires and the like; the base construction system is built by materials such as plastic, woods, soils, gravels, metal wires and the like; and the plant cultivation system consists of materials such as plants, plastic, soils and the like. The ecological engineering technology aims at land directional runoff pollution and side slope ecological structure construction of rural or urban suburban riverways, and has the advantages of fully and effectively collecting, detaining and purifying the land directional runoff pollution, particularly the runoff pollution of initial rain water, reducing the total amount of pollutants entering the riverway and realizing effective control on the riverway pollution; meanwhile, by the ecological engineering technology, a physical structure and a biologic structure of the riverway from the land direction to the water direction can be stabilized and perfected by building and restoring revetments and bases of the riverway, so a healthy, stable and developed riverway side slope biologic system is formed at last.

Description

Technical field: [0001] The invention belongs to the technical field of resources and environment, and relates to runoff water pollution control and shore zone ecological restoration project construction specially used for small and medium-sized river courses. Background technique: [0002] The river bank slope improvement project based on the traditional water conservancy engineering design code, such as the verticalization and hardening of the river bank, has played a pivotal role in the development of modern water conservancy in my country. The core of this traditional bank slope construction technology is that, firstly, the concrete structure with good construction performance and strong durability is mainly used as the material, which is especially beneficial to the safety and durability of the engineering structure; The ability to discharge floods, thereby reducing the risk of flood disasters, is conducive to ensuring the safety of people's property; the third is to ma...

AI Technical Summary

Problems solved by technology

This is because, with the sustained and rapid development of my country's social economy, the discharge of sewage into the environment is increasing day by day, water pollution is becoming more and more serious, and the self-purification and self-recovery capabilities of most rivers are reduced.

The root cause of the above results is that, in addition to the failure of simultaneous development of sewage and wastewater treatment, the adverse impact of the above-mentioned forms of water conservancy engineering design on it cannot be ignored.
