Ship ballast water collection device

Abstract

The invention discloses a ship ballast water collection device which comprises a hollow sealed water reservoir, and the water reservoir is connected with an air extraction pump and a water collection pipe respectively in a dismountable and sealed mode. The ship ballast water collection device provided by the invention collects and stores a water sample through aseptic operation, ensures that the collected water sample is not polluted, has great sampling amount, is convenient and rapid to take water and is applicable to different ships.

Description

technical field [0001] The invention relates to a water collection device, in particular to a ship ballast water collection device. Background technique [0002] In recent years, under the background of economic globalization, the ocean shipping industry has developed rapidly. 80% of the world's goods are transshipped by ships, and the resulting ballast water is about 10 billion tons per year. These ballast waters carry alien aquatic organisms and pathogenic microorganisms. With the indiscriminate discharge of ballast water in ports around the world, 3000-4000 biological species are spread around the world every day. The discharge of ballast water not only carries harmful bacteria that cause human health, but some biological species will cause serious harm to the local ecological zone and even lead to the extinction of local species. At present, it has caused many ecological environment and public health incidents. Therefore, the discharge of ballast water from ships has be...

AI Technical Summary

Problems solved by technology

However, as a collection tool for detecting aquatic organisms and pathogenic microorganisms carried in ballast water, the existing collection tools have the following deficiencies: First, the water intake of ballast water is small, with a diameter of only 2.5-2.8cm, and ordinary collection tools are No access to ballast tanks

Secondly, the volume of water samples collected by the collection instrument is small, most of which are less than 300mL, which greatly reduces the detection rate of aquatic organisms and pathogenic microorganisms

Secondly, the collection instrument with power is inconvenient to carry, and the centrifugal effect caused by the power pump often damages aquatic organisms to a certain extent and affects the stability of ballast water

Finally, the study of pathogenic microorganisms requires that the collection instruments must be thoroughly disinfected and sterilized. The current collection instruments cannot be sterilized, which will affect the accuracy of pathogenic microorganism detection results.
