Problems solved by technology

Although this method has played a very good role in the control of the clam, it also has certain defects: (1) the attachment row needs to be replaced in time, otherwise when the adult clam attached to the row grows to have the ability to reproduce, the attachment row It will become a source of marsh clam larvae, which will play a bad role
(2) Although the attachment row taken out from the attachment pond can continue to be used after killing the clams, but the continuous replacement of the attachment row not only affects the operation of the killing pond, but also requires a lot of manpower and material costs
This method has a good effect on killing clam larvae, but if there are impurities in the water, it will often block the orifice plate and affect the normal operation of the killing device

Embodiment Construction

[0054] In order to understand the content of the present invention more clearly, the following description will be made in conjunction with the accompanying drawings and specific embodiments.

[0055] Such as figure 1 and 2 As shown, a kind of clam killing pond device of the present embodiment is composed of killing pond front wall 5, killing pond rear wall 6, killing pond right side wall 7, killing pond left side wall 8 four pool walls The pool type device that encloses, the height of four described pool walls is 2.2m, and constitutes the top 9 of the killing pool, and the bottom 10 of the killing pool is a horizontal plane. In the killing pool, a water inlet 11 , a water outlet 13 , a water supply port 26 and an overflow port 28 of the water supply pool are sequentially arranged. In the killing pond, an overflow weir 25 and 11 settling zone separation weirs 18 (showing 3 in the figure) across the two side walls of the killing pond are arranged in the vertical flow directio...

Abstract

The invention discloses a limnopernafortunei killing pool device and a killing method. The device comprises a water inlet pool section, attachment-sedimentation killing pool sections, a sedimentation killing pool section and a water supply pool section which are sequentially connected in a penetrating mode. Each attachment-sedimentation killing pool section comprises an upper attachment area and a lower sedimentation area. Each attachment area is a water flow channel and comprises at least one attachment net, the net face of each attachment net is a gauze element which is of a small-diameter single-wire structure, the diameter of each net wire is 0.1-0.5 mm, and the hole diameter of each net hole is 1-10 mm. Each sedimentation area is a water purification environment. Due to limitation of the diameter and the hole diameter of the thin wires, enough attachment area can be provided for limnopernafortunei larvae, however, the bodies of limnopernafortunei adults cannot be supported sufficiently, and the adults can fall off naturally. Hence, the process of killing the limnopernafortunei adults after an attachment row is taken out from a pool is omitted, the killing pool device with the limnopernafortunei attachment-sedimentation killing pool sections can continuously operate without being interrupted, and meanwhile the operating cost of the device is lowered.

Description

technical field [0001] The invention relates to a clam killing pond device and killing method, in particular to the treatment of fouling biological clams in hydraulic structures such as pumped storage power stations and water delivery projects. [0002] technical background [0003] Marsh clam (Limnoperna fortunei) is commonly known as freshwater shellfish, the larval stage is plankton, and the adult stage is benthic organisms that live by camping or sessile. The clam larvae are tiny, move freely with the water flow, and have the biological characteristics of actively attaching to objects. The clam larvae can only develop into adults if they successfully attach to solid materials, otherwise they will die naturally. The adults of the marsh clam are attached to objects by their foot silk, passively feed on the water flow and continue to grow. Whether it is a larva or an adult, it will die naturally in a dehydrated environment. The clams grown in natural waters can be used as ...
