Abstract

The invention provides a ship ballast water treatment method and system. The ship ballast water treatment system comprises an electrolysis unit, a constant current supply device, a temperature detection unit, a salinity detection unit, a control unit and a rectifier. When the system works, according to the temperature and salinity of the ballast water measured in real time, the electrolytic current I currently required by the electrolysis unit is calculated by combining the electrolytic efficiency eta of the electrolysis unit and the relational data of the temperature and salinity of the ballast water, and automatic adjustment and control of the required electrolytic current are achieved. The system gets rid of a commonly used method for detecting residual chlorine through a residual chlorine concentration analyzer and reversely controlling electrolytic current, system shutdown caused by faults of the residual chlorine concentration analyzer is avoided, and the practicability and reliability of the system are improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a ship and a ship ballast water treatment system. Background technique [0002] Ship ballast water is water added on board to control the balance of the ship and improve the stability of the ship. According to the relevant regulations, before the ballast water of the ship is used up and discharged, it must be treated to make it meet the standards stipulated in the convention. Electrolysis is a relatively practical and commonly used ballast water treatment technology, which can kill most harmful aquatic organisms and pathogens in ballast water under certain conditions. [0003] The electrolysis method produces sodium hypochlorite through the electrolysis of seawater to treat the ship's ballast water. The chlorine concentration in the ballast water is detected by a residual chlorine analyzer. If the chlorine concentration exceeds or falls below the specified value, the sys...
