Filter ultrasonic and electrolytic ultrasonic ship ballast water treatment equipment and treatment method

Abstract

The invention discloses filter ultrasonic and electrolytic ultrasonic ship ballast water treatment equipment, and belongs to the field of water treatment equipment. The filter ultrasonic and electrolytic ultrasonic ship ballast water treatment equipment comprises a filter ultrasonic reactor and an electrolytic ultrasonic reactor; and the ship ballast water treatment equipment is sequentially connected with a sea chest, a ballast pump, a first pressure sensor, the filter ultrasonic reactor, a second pressure sensor, the electrolytic ultrasonic reactor, a third pressure sensor and a ballast tank. The invention also discloses a treatment method using the water treatment equipment. According to the equipment and the method, the defects of the prior art are overcome, the problems of low efficiency and high cost of the conventional method and equipment for treating ballast water are effectively solved, byproducts with equivalent level with seawater are not produced and preserved, and safe, practical, economic, effective and environmentally allowable requirements are met.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and in particular relates to a filtering ultrasonic and electrolytic ultrasonic ship ballast water treatment equipment and a treatment method thereof. Background technique [0002] The problem of foreign biological invasion caused by ship's ballast water has been and is threatening the marine environment, public property and human health, so it is very necessary to disinfect the ballast water. The International Maritime Organization proposes five standards for ballast water, namely safety, practicality, economy, effectiveness and environmental tolerance. There are many existing ballast water treatment methods for ships, such as mechanical filtration, heating, chlorine and chloride, replacement of ballast water on high seas, hydroxyl radicals, etc. However, exchanging ballast water on high seas has high energy consumption and long operating time Too long question, in the long run the best...

AI Technical Summary

Problems solved by technology

There are many existing ballast water treatment methods for ships, such as mechanical filtration, heating, chlorine and chloride, replacement of ballast water on high seas, hydroxyl radicals, etc. However, exchanging ballast water on high seas has high energy consumption and long operating time Too long question, in the long run the best way is to directly kill the large number of microorganisms in the ballast water on board

There are some problems in the above management methods that are difficult to solve.

Filtration method is considered to be the most harmless method to the environment, but it cannot remove micro organisms; chlorine and chloride method have problems such as gas poisoning and explosion, secondary pollution, corrosion and cost
