Detailed Description

The limnoperna lacustris, also known as concha meretricis seu Cyclinae, bivalve class, mussel family, and group-dwelling animals. The appearance is similar to a triangle, the shell is thin and hard, and the shell is attached to the secretory podium for survival, and takes plankton, organic debris and the like in the water for ciliated exercise; the proper water temperature for growth and reproduction is 16-28 ℃. At least 4N is required for the initial (0-6 months) attachment of the limnoperna fortunei on the concrete surfaceWhen stable fixation is formed on the surface (to 12 months), the adhesion strength is increased to 6-8N, and the raw adhesion amount is also rapidly increased to about 1200 pieces/m ² . If not treated, it can affect not only the life of the channel facilities, but also the quality of the water. The prior art mainly adopts the following treatment modes for the limnoperna lacustris:

1. physical cleaning method

(1) Manual or mechanical doctoring (anhydrous, water environment available): has the advantages of simple operation, quick effect and no influence on water quality. The defect is that the surface of the structure is easy to damage in the process of removing, and the structure needs to be repaired in time.

(2) Closed anoxic and water-free drying method (anhydrous environment): killing the limnoperna lacustris from the root.

(3) Flow rate was adjusted and the material was brushed (anhydrous environment): preventing the attachment of limnoperna lacustris.

(4) High pressure water jet removal method (anhydrous environment): the adhesive organisms are peeled off and washed away by using a jet flow of water (impact force is 3-5 MPa).

2. Chemical cleaning method

The fouling organisms are killed by adding or spraying chemical agents. The method has poor environmental protection and is not suitable for drinking water delivery engineering.

Chlorine is the most widely used water treatment disinfectant in water plants, is mainly used for removing algae and organic matters before, and has obvious killing effect on limnoperna lacustris after experiments. Sodium hypochlorite is the only medicament capable of dissolving the shredded foot of the limnoperna lacustris at present. The excessive disinfection byproducts can cause secondary pollution to the water body, so that the economic cost and the killing rate are comprehensively considered, and the dosage of the medicament has a reasonable range.

The chemical method is used for removing the limnoperna lacustris, the time is short, the effect is quick, but the selection, the adding amount, the action place and the action time of the type of the medicament need to be further demonstrated in consideration of the water body safety and the specific application requirements.

3. Biological elimination method

Biological methods refer to the use of biological chain relationships in the ecosystem.

One method is to breed fish feeding on limnoperna fortunei, commonly known as triangular bream, black carp, etc.

The biological method is suitable for open water bodies with smaller fluidity such as reservoirs, lakes and the like by combining actual production with the life habit discovery of fishes. However, compared with the physical and chemical methods, the method has long action period, can not be used immediately, and has higher requirement on water quality.

Through comprehensive analysis, the physical removal method has the advantages of simplicity, no influence on water quality safety and the like, and is a relatively ideal removal method. The physical cleaning method needs to be provided with matched cleaning equipment, and the underwater foreign matter scraping and cleaning device disclosed by the utility model is equipment capable of physically cleaning the limnoperna fortunei.
