A couple of days suddenly water become soo dirty. I wacuum some dirty from bottom, i clean 80% water yesterday but its still the same, i have this aquarium for more than 10 years and this is first time.

It looks like green water algae. That can be dangerous as it depletes oxygen, so add an airstone. Decrease the lighting and do some water changes to reduce it.

I read that UV light can fix this very fast, can i buy uv sterylizer like this even if not specificaly for aquarium?
Because my light is similar and maybe will fit.

No. You cannot use a naked uv bulb. It will be dangerous for you and your fish. If you must use uv get a proper uv steriliser with an enclosed bulb designed for aquarium use.
