If sun UV rays can poison purified water?

No it can't poison water. If that was the case nothing could live in or around water. Animals drink it. People drink it. Trees grow around and in water. Fish swim it. In fact, it's the opposite. UV rays can purify contaminated water. The SODIS method (look it up) is used in many countries around the world where clean water is not available. Water is put into a clean PET bottle and left in the sun for 6 hours. After that the water is clean and safe to drink.
