Comprehensive technology for ecological restoration of low-pollution river water

Abstract

The invention discloses a comprehensive technology for the ecological restoration of low-pollution river water. The technology constructs the low-pollution river water environment comprehensive control engineering treating flowing water as a base, treating ecological restoration as a core and giving consideration to the landscape improvement through the integration and optimization of ecologic restoration combination techniques comprising a water power control technique, a polluted basement restoration technique, an underwater microtopography shaping technique, an aquatic plant recovery technique, an aquatic animal restoration technique, an aquatic life reinforcement technique, a water landscape construction technique and the like. The comprehensive technology has a good pollutant removal performance, and the TN, NH3-N and TP reductions reach 75.5%, 84.5% and 92.0% respectively.

Description

technical field [0001] The invention relates to a comprehensive process for ecological restoration aimed at low-pollution river water bodies, and belongs to the technical field of environmental protection. Background technique [0002] With the rapid development of regional economy and the acceleration of urbanization, the problems of water quality pollution and ecological degradation of urban rivers have become more and more prominent. The large input of oxygen-consuming organic pollutants and nitrogen and phosphorus nutrients has led to the deterioration of urban river water quality, and even seasonal and perennial water black and odor phenomena. The deterioration of urban river water environment poses a serious threat to the life and health of urban residents and urban ecological security. Therefore, improving the water quality of urban rivers and restoring the ecological and social functions of rivers is one of the key tasks to be solved in the process of urban sustainab...

Problems solved by technology

These methods have their own advantages and disadvantages. For polluted rivers, due to years of continuous pollution, the ecological system structure has been seriously damaged. Simply relying on some physical and chemical methods cannot fundamentally solve environmental problems. We should start with restoring the structure and function of the river ecosystem and adopt comprehensive methods. Ecological restoration technology, by improving the basic environment, restoring aquatic plants, guiding the ecosystem to develop towards a grass-type ecosystem, and building a water ecosystem with a virtuous cycle, it can fundamentally improve water quality and improve the self-purification ability of water bodies
