Embodiment 1

[0036] Set up collection points on the edge of waters rich in cyanobacteria, and install related equipment such as water pumps and pumping pipes. The water rich in cyanobacteria is pumped from the water area and transported to the built irrigation pond through the pumping pipeline. Establish a fast-growing tree planting area with a certain slope on both sides of the irrigation pool. The slope slopes downward along the irrigation pool and the angle between the ground and the ground is 30°, which is generally in the shape of a dam; a drainage ditch is set on the side of the fast-growing tree planting area away from the irrigation pool. Choose bamboo and willow saplings (1.5-1.8m in height) that grow well, have a suitable size, and have no obvious pests and diseases, and transplant them to the fast-growing tree planting area at a density of 400 plants / mu. 60 days after bamboo and willow saplings are transplanted, the water rich in cyanobacteria in the irrigation pond is transport...

Embodiment 2

[0038]Set up collection points on the edge of waters rich in cyanobacteria, and install related equipment such as water pumps and pumping pipes. The water rich in cyanobacteria is pumped from the water area and transported to the built irrigation pond through the pumping pipeline. Establish a fast-growing tree planting area with a certain slope on both sides of the irrigation pool. The slope slopes downward along the irrigation pool and the angle between the ground and the ground is 45°, which is generally in the shape of a dam; a drainage ditch is set on the side of the fast-growing tree planting area away from the irrigation pool. Select poplar saplings (1.5-1.8m in height) with good growth, suitable size, and no obvious pests and diseases, and transplant them to the fast-growing tree planting area at a density of 300 plants / mu. 30 days after bamboo and willow saplings are transplanted, the water rich in cyanobacteria in the irrigation pond is transported to the fast-growing...

Embodiment 3

[0040] Set up collection points on the edge of waters rich in cyanobacteria, and install related equipment such as water pumps and pumping pipes. The water rich in cyanobacteria is pumped from the water area and transported to the built irrigation pond through the pumping pipeline. Establish a fast-growing tree planting area with a certain slope on both sides of the irrigation pool. The slope slopes downward along the irrigation pool and the angle between the ground and the ground is 15°, which is generally in the shape of a dam; a drainage ditch is set on the side of the fast-growing tree planting area away from the irrigation pool. Select pagoda tree saplings (1.5-1.8m in height) with good growth, suitable size, and no obvious pests and diseases, and transplant them to the fast-growing tree planting area at a density of 200 trees / mu. 45 days after bamboo and willow saplings were transplanted, the water rich in cyanobacteria in the irrigation pond was transported to the fast-...

Abstract

The invention discloses a method for treating blue algae by a fast-growing tree. The method comprises the following steps: conveying water rich in blue algae next to a water area to an irrigation pool by a water pump; conveying water rich in blue algae in the irrigation pool to a fast-growing planting area with a certain slope, fixing blue algae to the surface soil by means of the fixing effect of a fast-growing tree root system to the blue algae and the filtering effect of soil, and returning treated water to a drainage ditch at the edge of a slope of the fast-growing planting area; carrying out self settling on water in the drainage ditch to remove silts and flowing into a water storage pond; opening a gate to release clean water in the water storage pond periodically and returning to the water area. The method disclosed by the invention not only can remove blue algae in the water body, but also can absorb nutritional elements such as nitrogen, phosphorus and potassium in the water body by the fast-growing tree roots so as to thoroughly change the composition and structure of the water body which is needed to survive by blue algae, thereby fundamentally treating blue algae.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for treating cyanobacteria with fast-growing trees. Background technique [0002] Cyanobacteria is the most important type of planktonic algae produced by the eutrophication of many inland lakes in China and the world. It exists in water bodies and brings endless harm to people, such as destroying ecosystems, polluting water sources, and endangering human health. And emission of odor pollution air and so on. According to research, more than 66% of lakes and reservoirs in our country are in the state of eutrophication, of which 22% are heavy eutrophication and super eutrophication. major water environmental problems. Water blooms caused by blooms of algae such as cyanobacteria are a prominent manifestation of this problem. Due to the simple structure of cyanobacteria and extremely strong fecundity, the control of cyanobacteria in Taihu Lake...
