Limnopernafortunei killing pool device and killing method

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 marsh clam killing pond device and a killing method, in particular to the treatment of fouled biological clams in hydraulic structures such as pumped storage power stations and water delivery projects. technical background [0002] Limnopernafortunei is commonly known as freshwater clam. The larval stage is plankton, and the adult stage is benthic organisms that attach or stubbornly live. The larvae of the larvae are small, move freely with water currents, and have the biological characteristics of actively attaching objects. The larvae of the larvae can develop into adults only if they successfully attach to solid materials, otherwise they will die naturally. Adult clams attach to objects by foot silk, eat passively by the flow of water and grow up continuously. Both larvae and adults will die naturally under dehydration. Marsh clams grown in natural waters can be used as bait for fish or as food for humans and are beneficial o...

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
