Abstract

The invention discloses a manufacture method of a light vegetation floating bed. The light vegetation floating bed is manufactured through the following steps that aluminum powder balls are manufactured, the light balls are foamed, three through holes perpendicular to one another are drilled in each foamed light ball through a ball center drill, ropes are made to penetrate the through holes so that the foamed light balls can be connected to form a cube, and the light vegetation floating bed is obtained. The manufacture method is simple, and the size of the floating bed can be designed according to engineering requirements; the manufactured light vegetation floating bed shows a low density and large buoyancy and is good in floatability on water surfaces; and the crushing index is low, the water erosion resistance is good, and the storm impact resistance is good. The aluminum powder balls are manufactured first, then, the light vegetation floating bed is manufactured, the reaction speed is easily controlled, and the phenomenon that because foaming is conducted too early, bubbles are broken in the stirring process and the buoyancy of the light vegetation floating bed is influenced is prevented.

Description

Technical field [0001] The invention relates to the field of prevention and treatment of eutrophication of water bodies, in particular to a method for preparing a lightweight plant-growing floating bed. [0002] technical background [0003] When lakes, wetlands and other water bodies reach a state of eutrophication, algae rapidly multiply to shade the sun, causing underwater plants to die and rot due to lack of photosynthesis and release nitrogen and phosphorus. At the same time, the amount of dissolved oxygen in the water dropped sharply, causing fish and other organisms to suffocate and die. Over time, a vicious circle will eventually seriously damage the ecological balance of water bodies. There are more than 2,700 lakes in my country, with a total area of ​​91,000 km 2 According to survey data and evaluation of lake eutrophication indicators at home and abroad, among the 37 major lakes in China, the mesotrophic and middle-one eutrophic type account for 55.8%, the eutrophic ty...
