The Ship Ballast Water Convention has come into force, and many countries around the world have adopted unilateral protectionist policies based on their actual conditions. This paper introduces the present situation of ballast water legislation, treatment technology, biological detection and shore-based reception in China. The results show that the legislation of ballast water in China is relatively late and mainly refers to international conventions or foreign laws and regulations. Ballast water treatment technology has been in the leading level, technical solutions cover electrolytic, UV and other mainstream directions; There are many ballast water sampling institutions, and most of them have IMO-D2 testing qualification. Our country has the shore-based receiving capacity, but there is a lack of actual port installation and receiving cases. China"s ballast water treatment technology and detection technology is relatively advanced, but the legislative protection and shore-based reception still need to be further improved.
