Problems solved by technology

Because there may be different microorganisms in different water bodies, even actinomycetes may also have different types of actinomycetes, and the addition of foreign bacteria may cause micro-ecological damage
Indigenous microbial technology is to strengthen the control by expanding the number of all bacterial species in the original water body and increasing the overall microbial base, but there are also bacteria that have a deteriorating effect on the environment such as the original indigenous microbial bacteria and poisonous bacteria. The increase in the number caused the original environment to be worse, and increased the harm to the water body. Therefore, a water body ecological restoration method is proposed to solve this problem.

Embodiment 1

[0036] When the water body is out of balance, exogenous pollutants should be controlled first, and the sewage should be intercepted and treated by building storage dams in the river; the floating objects on the water surface should be collected and cleaned, so that the depth of light transmission at the bottom of the water can reach 1-1.5m. A 10x10cm mesh cotton net with a depth of 0.8-1.2m is placed at the water inlet; for the control of internal pollutants, combined with the actual situation of the silt environment on site, a dredging disposal plan is formulated, environmental dredging projects are carried out, and silt disposal and reuse are carried out; submerged plants are planted: Take a non-woven fabric to make small square holes with a diameter of 4-6cm, and mix 7 submerged plants of hornwort, foxtail algae, bamboo leaf eye vegetable, black algae, weed, bitter grass and waterwheel at a ratio of 1:1. The ratio of 1:1:1:1:1 is inserted into the small hole of the non-woven...

Embodiment 2

[0038] In embodiment one, add following operation:

[0039] In step 1, the control of exogenous pollutants includes sewage interception and treatment projects. A large amount of domestic sewage is directly discharged into the water body without effective treatment, causing a large amount of pollutants to pollute the target water body. In order to achieve long-term effective water quality control goals, the Directly discharge sewage around the surrounding area for sewage interception, build storage dams in the river, design and build rubber dams and fishing net fences, which can effectively store water, ensure the continuous flow of the river in all seasons, meet the flood discharge function of the river, and use it to grow aquatic economic crops and farm fish Shrimp, turn sewage into resources.

[0040] When the water body is out of balance, exogenous pollutants should be controlled first, and the sewage should be intercepted and treated by building storage dams in the river; ...

Embodiment 3

[0042] In embodiment two, add following operation:

[0043] In step 3, mechanical dredging removes most of the black and smelly bottom sludge, and the remaining black and smelly bottom sludge is controlled by biological dredging. The beneficial microbial system on the mud surface consumes organic matter, nitrogen, phosphorus and other pollutants in the bottom mud through the metabolism, division and proliferation of microorganisms, so it can effectively control the release of pollutants in the black and odorous bottom mud. Combined with the actual situation of the silt environment on site, formulate a dredging disposal plan, carry out environmental dredging projects, silt disposal and reuse; the design of the bottom improvement project needs to improve the bottom of the river before the construction of the water ecosystem to meet the requirements of submerged water. Planting requirements, promote the formation of a healthy and stable water ecosystem as soon as possible; the nu...

Abstract

The invention relates to the technical field of ecological environment restoration, and discloses a water body ecological restoration method. The invention aims to provide a water body ecological restoration method. A water bottom forest system is constructed in a flowing water area and a still water area of a river by planting submerged, floating and emergent aquatic plants by an in-situ covering method and a throwing method, and fishes and shellfishes are thrown into the river. After the water body is restored, a complete ecological system is formed, the river has ornamental value, and the underwater ecological system keeps benign operation. The problem that the addition of different microorganisms (different types of actinomycetes) and foreign strains may cause damage to the micro-ecology, the number of bacteria, such as infectious microbes and toxic bacteria, which have a deterioration effect on the environment, of original indigenous microorganisms is increased, the original environment is more severe, and the harm to the water body is increased is solved.

Description

technical field [0001] The invention relates to the technical field of ecological environment restoration, in particular to a water body ecological restoration method. Background technique [0002] In recent years, the country has paid more and more attention to environmental protection issues. On the one hand, it has strengthened the people's awareness of environmental protection, and on the other hand, it has vigorously developed environmental governance technologies. Therefore, in response to the call of the state, a large number of environmental governance methods have been actively developed, including physical methods, chemical methods, and biological methods. Among them, the physical method has a large amount of work, poor effect, and complicated operation; the chemical method is often based on sedimentation and flocculation, which makes it difficult to clean up the sediment, and is easy to carry other chemical elements into it, resulting in a temporary problem rather ...
