Embodiment Construction

[0018] The present invention will be described in detail below through specific embodiments.

[0019] Select the water area that needs to be treated, then salvage and clean up the algae in the water as much as possible, and then start to build the floating bed on the water surface: select a number of bamboo poles with a diameter of about 80--120mm, and fix them in a criss-cross pattern to form a grid with a spacing of 70-80mm. Cannas are planted at the intersecting points of each grid, and the cannas are fixed on the floating bed frame through a ring with adjustable circumference. The ring is set as a double-layer ring structure that is easier to fix and stabilize the plants.

[0020] Put biological growth promoter BE and biological detoxifier MT in the water body to promote the growth of aerobic bacteria and facultative bacteria in water, and use local aerobic bacteria and facultative bacteria to degrade organic pollutants in water.

[0021] Then, duckweed is introduced into ...

Abstract

The invention discloses a comprehensive treatment method of contaminated water ecological restoration, which is used in the water where the plants eliminating the blackness and ugliness basically can grow. The method comprises the following steps: 1. cleaning the algae in the water; 2. throwing the one or a plurality of bio-energizers and bio-antidotes in the water; 3. putting up the floating bed frames for fixing and planting the land plants; 4. planting land plants between floating bed frames at intervals or adopting the floating bed to create the condition for the local duckweed growth; 5. planting floating plants in the unit frame lattice of the floating bed frame; 6. examining the restraining and death borne by the algae in the substrate sludge in the water and deciding whether to clean the floating plants on the water surface. The method realize the indirect control of the algae in the water by controlling the floating plants easily controlled on the water surface and is an effective method for changing the algae water into the grass water. The method is the third synthetic method of urban arrangement dam engineering and can have effect like that one and one is more than two with other river control synthetic method via test.

Description

technical field [0001] The invention relates to a comprehensive treatment method for ecological restoration of polluted water bodies, and is especially suitable for cleaning and water body restoration caused by overgrowth of algae in eutrophic water bodies, and belongs to the field of environmental protection and treatment. Background technique [0002] In the remediation of water pollution caused by eutrophication, such as rivers and lakes, biological, physical, and chemical methods are mainly used at present, and the main disadvantages of these existing methods are high cost or easy to produce secondary pollution. For the main source of pollution algae, the physical method of multiple salvage is adopted, the algae will always come back and attach to the bottom mud, and it will not be a big problem to remove a small part of the water surface. When algaecides are used in chemical methods, although the short-term reduction is obvious in a few days, it will still dominate afte...
