Embodiment 2

[0052] Treatment of eutrophic water body in Gejiashan Slot Lake, Kaihui Township, Changsha County:

[0053] Flowchart see image 3 .

[0054] A kind of method adopting the double-tube circular floating frame of embodiment 1 to fix green foxtail algae to control eutrophic water body, its steps are:

[0055] 1. First remove the solid waste in Slot Lake:

[0056] 2. Install and fix the double-tube circular floating frame: the double-tube circular floating frame is made of PPR material. The diameter of the floating frame is designed to be 5m and 10m, and it is wrapped with a nylon fishing net with a mesh of 2-3cm, without a cover, forming a height of 30cm. s frame. Eight wooden stakes are installed around the lake, wedged into the ground at a depth of 0.6 meters, and used to fix the floating frame in the water body. Each floating frame is fixed with wooden stakes on the shore by three plastic ropes.

Abstract

The invention provides a floating frame for fixing myriophyllum elatinoides and a method for treating eutrophic water, and belongs to the technical field of water pollution treatment. A floating base comprises an outer floating support body and an inner floating support body; wherein the outer floating support body and the inner floating support body are connected through a connecting piece; the inner floating supporting body is connected with a fixing frame through a supporting stand column; an intercepting net is arranged along the periphery of the fixed frame and the inner floating support body. The floating frame is easy to manufacture, easy to popularize, low in cost, convenient to move, high in stability and capable of being repeatedly used. The invention further provides a method for treating the eutrophic water body based on the floating frame for fixing myriophyllum elatinoides. The method is simple and easy to implement, nitrogen and phosphorus in the eutrophic water body are effectively removed, and meanwhile the environment of the eutrophic water body and the stability of a water body ecological system can be improved.

Description

technical field [0001] The invention relates to the technical field of water pollution control, in particular to a floating frame for fixing green foxtail algae and a method for treating eutrophic water body. Background technique [0002] Eutrophication refers to that under the influence of nature and human activities, the concentration of nitrogen, phosphorus and other nutrient elements in surface water bodies such as lakes and rivers increases sharply, causing algae and other plankton to grow and reproduce in large numbers, and the DO concentration in water bodies The water quality deteriorates seriously, aquatic plants and animals die in large numbers, and the balance of the aquatic ecosystem is destroyed. The increase of nutrients such as nitrogen and phosphorus is the root cause of eutrophication in water bodies. Excessive nitrogen concentration in water bodies will cause phytoplankton and algae to multiply, cover the water body, reduce the transparency of the water bod...
