Water surface anti-pollution duck

In recent years, more and more attention has been paid to water pollution caused by ducks. Special attention has also been paid to exploring various antifouling aquaculture laws. The caisson-type anti-pollution network technology of the duck farm in Shaoxing County has the advantages of obvious anti-fouling function, simple and easy to use, and the use of a common nylon net for the caisson. The cost per square meter of water is only 2.5 yuan per square meter. About 0.3 yuan per duck or on the other hand, generally duck farmers can afford it, it is worthwhile to farms (households).

The so-called “caquet-type anti-pollution net” technology is to use a fine nylon net to surround the waters of ducks in a river or lake with a wide water surface and smooth water flow in the plain river network area. Because of the fine meshes, the dirt in the water will be By blocking most of the mesh, the water in the duck area is separated from the water in the main channel to prevent contamination of the entire river. The specific approach is as follows:

The site of choice is to choose a place with a wide river bed and a stable flow of water. A certain area of ​​stocking water is surrounded by the shore and the bamboo is piled on three sides. The bamboo piles are separated by about 2 meters.

The cloth net purchases a special high-density nylon net from the market, and fixes the nylon net on the bamboo pile, extending from 1 meter away from the water surface to the bottom of the river and forming a “cacellar box”. After a period of time, the debris in the river will block the mesh and cut off the culture water from the water outside. The stocking ducks are restricted to activities within the nylon net.

Purification occasionally sprinkle some complex water purification bacteria in the water, through the action of microorganisms, can decompose some of the organic matter, to achieve the effect of purifying water quality. Water hyacinth and other aquatic plants can also be cultivated to absorb excess nutrients such as nitrogen and phosphorus in the water.

Decontamination Since the caisson network is separated from the external water body, all the duck dung will be deposited in the area where ducks are raised. Therefore, it is necessary to periodically clean the sewage and suck away the sediments and sludge deposited in the water.
