Problems solved by technology

[0004] For the ecological restoration of river water pollution, at present, more attention is paid to the structural adjustment of the river ecosystem, focusing on the construction of micro-habitats, such as building deep pools and shoals through spur dikes and other measures to provide habitat space for aquatic organisms; Increase

Embodiment Construction

[0018] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings will be used for a detailed description, as follows:

[0019] Such as figure 1 As shown, a method for ecological restoration of a near-natural river, including maintaining the river course, cleaning the rainwater pipe for sewage outlet pretreatment, and controlling and maintaining the water quality. Beneficial bacteria water bioremediation process, artificial plant floating island process and submerged plant ecological restoration process.

[0020] The most common way to deal with sediment is to dredge the sediment. However, not only the cost of dredging is high, but the advantages and disadvantages of dredging have not yet been determined in the international academic circle. Unsuccessful dredging will lead to the release of more pollutants in the lower sediment. , and is not conduc...

Abstract

The invention relates to an ecological restoration method of river close to nature, which comprises riverway maintenance, sewage draining exit pre-treatment and rain pipe cleaning, and water quality control treatment and maintenance. The water quality control treatment and maintenance comprises bottom mud organic matter locking technology, river bottom micropore aeration technology, beneficial bacterium water body biological restoration technology, artificial plant floating island technology, and submerged plant ecological restoration technology. According to the invention, engineering manners, such as ecological restoration and recovery, are applied, and inflow of pollutants is reduced; the ability, for decomposing organic matters, of water body microorganism is enhanced, and a self-cleaning function of the water body is maintained; and a complete aquatic food chain is built and mass growth of algae is prevented, so that the purpose of maintaining and improving water quality is achieved. The water system is allowed to be an ecological system which is capable of self-maintenance, and has virtuous circle and vitality, and can provide a living environment for animals and plants, so that harmonious coexistence of human and nature is realized.

Description

technical field [0001] The invention relates to a method for ecological restoration of a near-natural river. Background technique [0002] Pollution is one of the important causes of damage to river ecosystems. At present, with the emphasis on the control of point source pollution and the improvement of governance capacity in our country, non-point source pollution has become an important factor affecting the quality of water environment. Especially in the vast rural areas, in order to survive, people wantonly reclaim the beaches on both sides of the river to engage in agricultural production activities; in order to increase economic income and gradually increase the investment in agricultural production, unused pesticides, herbicides, and nitrogen and phosphorus nutrients are scattered on the ground surface. The runoff enters the river and pollutes the water quality. In order to be used, its production process is basically reclaimed into farmland. Therefore, the control ...
