An environmental-friendly ship ballast water treatment method comprises the following steps:
(1) conveying the seawater to a first pH value detection device through a water pump, wherein the first pH value detection device obtains the pH value a of the seawater and transmits the pH value a to an upper computer;
(2) filtering and separating the seawater subjected to pH detection by a cyclone separator;
