Abstract

The invention aims to provide a ballast water treatment device based on the combined effect of visible light and ultraviolet light. The device comprises a primary filter device, a venturi tube ejection device, a catalytic reaction unit and a catalyst recovery unit, wherein the catalytic reaction unit comprises a cylinder; each of an inlet end and an outlet end of the cylinder is fixedly provided with a perforated plate; dispersed optical fibers are fixedly arranged between the two perforated plates; the perforated plate at the inlet end of the cylinder is provided with a through flow hole; the inlet end of the cylinder is connected with an outlet of the venturi tube ejection device; a reflecting cover is arranged at the outlet end of the cylinder; a light source is arranged in the reflecting cover; the catalyst recovery unit comprises a high gradient magnetic filter; the outlet end of the cylinder is provided with an outlet; the outlet is communicated with the high gradient magnetic filter; the high gradient magnetic filter is communicated with a ballast water cabin and a water tank respectively; the water tank is communicated with the throat part of the venturi tube ejection device; an inlet of the venturi tube ejection device is communicated with the primary filtering device; a stirring device, a water injection device and a concentration monitoring device are arranged in the water tank. The device is energy-saving, high-speed and free of secondary pollution.

Description

technical field [0001] The invention relates to a ballast water treatment device. Background technique [0002] Biological invasion caused by ballast water has become one of the four major problems facing the world's marine ecological environment in this century (Global Ballast Water Management Project China National Project Implementation Team. Global Replacement Ballast Water Management Project. Transportation Environmental Protection, 2001, 22 (1): 1-4.). When the ship is empty, the ballast water loaded can reach 1 / 3 of the ship's deadweight at most (Liu Zhaoqing. Overview of the International Convention on the Control and Management of Ships' Ballast Water and its Sediments. Transportation and Environmental Protection, 2004, 25(2): 16- 20.), and when it is full of cargo, it is also filled with ballast water (Chen Huang, Gan Xingqi. Analysis of the International Convention on the Control and Management of Ships’ Ballast Water and its Sediments. World Shipping, 2004, 28 (...
