Biochemical reactor for bacterial colonies in ship ballast water

Abstract

The invention discloses a biochemical reactor for bacterial colonies in ship ballast water, relating to the technical fields of ocean shipping and offshore oil engineering. The biochemical reactor concretely comprises a shell and a rotator; a fluid in a main region forms a pressure difference under the centrifugal action of the rotator so that a fluid in a bacterial colony region generates a one-way flowing characteristic; and meanwhile, bacterial colonies in ballast water only move outwards through small filtering holes under the action of a tangential rotational flow of a fluid such as luciferase and an adjuvant outside the rotator, while fluids such as luciferase, fluorescein and an adjuvant outside the rotator cannot permeate or enter the rotator, then, low-concentration bacteria in the ballast water are gathered towards the main region, bacteria ATP can be sufficiently mixed with the luciferase and the adjuvant in the main region, then biochemical reaction is carried out, and bright light is emitted for realizing the detection of a photoelectric sensor, so that the amount of the bacterial colonies is qualitatively judged. Due to the adoption of the structure, a biological membrane in the traditional reactor is not needed to be maintained and replaced, the economic efficiency and reliability of equipment are improved, and meanwhile, the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical fields of ocean-going ship transportation and offshore oil engineering, in particular to a luminescent biochemical reaction device for bacterial colonies in ship ballast water. Background technique [0002] In order to maintain the stability and seaworthiness of ships in oceans and lakes, ballast water tanks are provided on ships, and the ballast water tanks must be loaded with a certain amount of ballast water. Every year, more than 1 billion tons of marine ballast water is transferred between global hub ports on the earth. Aquatic organisms (including microorganisms or bacteria) living in the harbor are mixed in the ballast water, and these aquatic organisms will be transported to foreign countries along with the transportation of the ship. As a result, species that did not exist in the sea area will invade the original ecosystem and pose a competitive threat to the existing indigenous species. [0003] In the...

Problems solved by technology

However, its cost is high, it is easy to pollute, it needs regular maintenance, and its service life is short (2-3 years). It is not very convenient for biofilm to be used in ship ballast water treatment.
