Embodiment Construction

[0011] 1. Interception facilities and pollution source control

[0012] If the non-point source pollution around the reservoir is serious, it is necessary to control the surface runoff formed by rainfall. Build rain-collecting troughs to collect runoff and discharge it into the reservoir. At the same time, do a good job in planting trees and grass around the reservoir to intercept surface pollutants. Ban all point source pollution activities around the reservoir, such as farms and cage farming.

[0013] 2. Changes in the direction of water flow

[0014] According to the shape of the reservoir, use the waterproof cloth to change the flow direction of the water body, so that the time for the incoming water to stay from the water inlet to the water outlet is longer, prolonging the time of being biologically treated by the water body, and achieving better governance effects; or making the local dead water flow. , Prevent the accumulation of algae. The upper end of the tarpauli...

Abstract

The invention relates to a method for the eutrophication treatment of deepwater of reservoirs. The method is characterized in that an ecologic idea is used as a core guiding idea of treatment to build or restore a complex ecological water system structure in order to restore the self functions of the ecologic water system. Proper physical measures are combined on the basis of knowing the reservoir characteristics to realize the development toward a healthy direction. The method mainly comprises the steps of (1) control of the pollution source in a river basin; (2) reasonable arrangement of the flow direction of water; (3) plantation of aquatic higher plants or herbaceous plants on a floating bed; (4) plantation of submerged plants on a platform in water; (5) change of the fish structure; (6) stocking and hanging breeding of benthonic animals comprising mussels and snails; (7) hanging of a biological membrane in order to provide an adherence for microorganisms and the like; (8) construction of a constructed wetland or plantation of emerged plants in the shallow position of the tail of water reservoirs; and (9) plantation of drought and flooding tolerant herbaceous plants in the falling zone. The method does not bring secondary pollution to the water in the treatment process, and is especially suitable for the eutrophication treatment of water in a water source.

Description

Technical field [0001] The present invention involves a reservoir water body rich nutritional governance technology, and is also applicable to the rich nutritional governance of other deep -water freshwater bodies. Background technique [0002] The pollution problems brought about by the rapid economic growth of my country are increasingly prominent, especially the water pollution on the surface, and most of the rivers and lakes are contaminated to varying degrees.Among them, the problem of rich nutritionalization. The water bodies such as Taihu, Dianchi, Chaohu, and other water bodies have successively erupted in the water, which affects the water supply of millions of people. This type of incident has sounded the alarm.As the pollution of rivers and lakes intensified, the source of water gradually transferred to the reservoir, and the water supply function of the reservoir was increasingly prominent.Cities in coastal areas have rare natural lakes due to the limitation of terrai...
