Abstract

The invention discloses an electrolytic coupling LED photocatalytic tandem halide removal ballast water treatment device. The ballast water treatment device comprises a filter unit, an electrooxidation-LED photocatalytic device and a halide removal device, and is characterized in that the electrooxidation-LED photocatalytic device is internally provided with an electrode and an oxidant adding device; an electrode is arranged in the halide removal device; the ballast water is subjected to pretreatment of removing silt and suspended particles through the filter unit, then enters the electrooxidation-LED photocatalytic device for biological inactivation, and finally enters a residual chlorine removal device for dehalogenation treatment, so that the toxicity of the ballast water is reduced. When the device is used for ballast water treatment, various treatment methods have a synergistic effect, the treatment effect is good, the inactivation rate of aquatic organisms in the treated ballastwater is high, and the toxic harm to a natural water body is low.

Description

technical field [0001] The invention belongs to the technical field of ballast water treatment, and in particular relates to a ballast water treatment device for removing electrolytically coupled LED photocatalyzed serial halides. Background technique [0002] The function of the ship's ballast water is to control the draft, stability or stress of the ship, and to maintain the balance of the ship's ballast by inhaling or discharging ballast water is a necessary condition for the safe navigation of the ship. However, ballast water carries a large number of harmful organisms and pathogenic microorganisms, which need to be purified before being discharged. [0003] Aquatic organisms in ballast water include plankton, algae, microorganisms, spores, etc. The inhalation and off-site discharge of ballast water will cause biological invasion, destroy the ecological balance, and threaten marine ecology and human safety. Some crustaceans in ballast water will cause corrosion of the h...
