Embodiment 1

[0052] Implementation example one is the method of the present invention; implementation example two is the device of the present invention.

[0053] Implementation example one

[0054] A new type of ballast water treatment method is characterized in that: no chemical substances are added during the treatment process, and it is realized only through a combination of mechanical, physical and electrochemical methods; it includes the following steps:

[0055] A. Mechanical treatment: remove organisms larger than 50 μm in ballast water by filtration;

[0056] B. Combined physical and electrochemical treatment: ultrasonically crushing and removing organisms and controlling the amount of hydroxyl free radicals produced to remove residual organisms in the ship's ballast water treated in step A;

[0057] C. Discharging the ship's ballast water that has been processed in step B.

Embodiment 2

[0059] See figure 1 and figure 2 , figure 1 The pipeline in A is the same as figure 2 The pipes in are integrated at B. A ballast water treatment device, which includes a valve, a ballast water pump 1, a power supply and pipelines, is characterized in that it also includes a filter part 3, a treatment part 6 and a control part 5; the filter part includes a filter unit, a backwash unit and a control unit unit; the processing part is composed of an electrocatalytic unit and an ultrasonic unit; the control part includes an automatic control unit, a monitoring unit and an alarm unit for the system; the monitoring unit includes a conductivity sensor 2, a flow sensor 4 and a total residual oxide sensor 7; the ballast One side of the water pump is connected to the front-end water inlet pipe, and the other side is connected to the rear-end water inlet pipe; the conductivity sensor is installed on the rear-end water inlet pipe; the rear-end water inlet pipe is connected to the fil...

Abstract

The invention relates to the technical field of environmental protection, in particular to a water treatment method and a device. The novel water treatment method is characterized by being realized only by a mechanical method and a physical and electrochemical combining method without adding any chemical substance in the treatment process. The method comprises the following steps: A. the treatment by the mechanical method: removing organisms more than 50mu m in the ballast water by filtering; B. the treatment by the physical and electrochemical combining method: removing the organisms by crushing in an ultrasound mode and treating residual organisms in the ballast water by controlling the amount for generating hydroxyl free groups; and C. treating finished ships through the step B and discharging the ballast water. The invention introduces a device adopting the method. The invention has the beneficial effects that the novel water treatment method can be simultaneously applied to sea water or fresh water to sterilize and remove algal, has better effects of sterilizing and removing algal, can realize automatic scale removal, has simple equipment and wide application range and ensures safety environment without generating secondary pollution.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method and device for treating ballast water through physical filtration, ultrasonic algae killing, and electrocatalytic sterilization. Background technique [0002] The invasive spread of alien pests is one of the four major threats facing the ocean, and the ship's ballast water is the most important way of spreading pests. Treating the ship's ballast water is the best way to solve the pest invasion caused by the ballast water. Due to the huge amount of ballast water loaded on ships and the short time required to treat ballast water, coupled with the constraints of the marine environment and the sustainable development of the marine economy, general methods of killing microorganisms cannot meet the requirements for the treatment of alien biological invasion in ship ballast water. requirements. Although some methods are successful and effective in the laborat...
