Abstract

The invention discloses an in-situ ecological restoration method, system and application suitable for sewage outfalls of tidal inland river systems (including rivers and lakes). The sewage outfall is diverted through the flexible enclosure, and the water plant absorption area, the aerobic reaction area of ​​the efficient microbial film and the facultative anaerobic reaction area are built in the diversion channel from the top to the bottom of the water surface, and the biological contact oxidation technology, The comprehensive efficiency of high-efficiency biological carrier technology, high-efficiency microbial technology, micro-aeration technology and biological manipulation technology purifies water through physical precipitation, carrier adsorption, microbial degradation, plant absorption and transfer, and aquatic animal digestion and decomposition. The invention provides foraging and habitat space for aquatic animals such as fish, snails, shrimps and plankton, provides a good micro-ecological environment, forms a set of healthy water ecological system, saves investment, occupies less land, and does not affect the water surface landscape, The removal efficiency of pollutants is high, and it can be widely used in the water purification of tidal rivers, sewage outlets of lakes and ponds.

Description

technical field [0001] The present invention relates to the technical field of polluted water treatment and ecological environment restoration, and more specifically, relates to an in-situ ecological restoration method suitable for sewage outfalls of tidal inland river systems (including rivers and lakes), and methods for realizing the method systems and applications. Background technique [0002] In many areas of my country, especially in the Pearl River Delta region, urbanization is developing rapidly, but the supporting sewage pipe network facilities are not perfect, especially in the old urban areas and urban-rural fringe areas, where sewage interception is not complete, and untreated sewage is discharged into nearby rivers. The phenomenon of lakes and ponds is still common; the water exchange in the tidal river network area of ​​the Pearl River Delta is not smooth, and the excessively high organic load far exceeds the self-purification ability of the water body, resultin...
