application example 1

[0089] The present invention is applied to a ship's ballast water online monitoring system, and corresponding detection devices are installed on the ship to detect the concentration of plankton in the ballast water in real time according to the use requirements, so that relevant personnel can have a better understanding of the ballast water in the ballast tank. An intuitive understanding that meets the needs of real-time monitoring. It can also realize the regular automatic detection function, set the detection cycle, and automatically store the detection results. When the detection results are unqualified, it will automatically alarm the personnel in charge, and the staff will intervene and further process the ballast water.

application example 2

[0091] The present invention is applied to a rapid detection system on site, and is suitable for the requirement of rapid detection of ballast water of maritime law enforcement departments. The relevant equipment required by the present invention is integrated into a set of portable detection devices. Maritime law enforcement officers can use this equipment to efficiently and conveniently detect whether the ship's ballast water meets the discharge standards at the law enforcement site, reduce the difficulty of detection by maritime law enforcement personnel, and at the same time greatly reduce Detection time.

[0092] In summary, the present invention utilizes spectrophotometry to calculate the concentration of chlorophyll a in ballast water, and then converts the concentration of living biomass; multiple groups of absorbance data can be obtained through repeated measurement at a higher frequency, and through statistical analysis of these data, effective Reduce and improve the...

Abstract

The invention discloses a microalgae cell biomass detection system for ship ballast water and a method. The system comprises a sample introduction chamber, a concentrating device, a wastewater tank, abackwashing device, a cracking chamber, a circulation tank and a recovery device and a spectrograph, wherein an inlet of the concentrating device is connected with an outlet of the sample introduction chamber; an inlet of the wastewater tank is connected with a first outlet of the concentrating device; an outlet of the backwashing device is connected with the first outlet of the concentrating device; an inlet of the cracking chamber is connected with a second outlet of the concentrating device; an inlet of the circulation tank is connected with an outlet of the cracking chamber; and an inletof the recovery device is connected with an outlet of the circulation tank. According to the system and the method, the system for detecting microalgae cell organisms with the particle size of 10 to 50 microns in the ship ballast water is designed by means of measuring chlorophyll a by spectrophotometry on the basis of a long-light-path circulation tank and has the advantages that the device structure is simple, the operation is convenient, the detection process is rapid and efficient, the dependence on fluorescent dyes is absent, the restrictions to ship swing and the like are absent, and a means for effectively and rapidly supervising the ballast water is provided for law-enforcing departments such as Department of Maritime Affairs, Department of Inspection and Quarantine and the like.

Description

technical field [0001] The invention relates to the technical field of microorganism detection in ship ballast water, in particular to a detection system and method for microalgae cell biomass in ship ballast water. Background technique [0002] The invasion of alien organisms that spread with ships' ballast water has caused serious environmental hazards and huge economic losses worldwide, so it has attracted more and more attention. The IMO (International Maritime Organization) "Ballast Water Convention" has come into force on September 8, 2017, and the maritime authorities will soon conduct PSC inspections on ships arriving at the port to which this Convention applies. As a major shipping country, the entry into force and implementation of the Convention have put forward urgent requirements for the ability of my country's maritime administration to perform the Convention. [0003] According to the "Ballast Water Convention", the ballast water standard is divided into two ...
