What happened to object in ZODB when I del this?

It's a bit complicated, but in essense it's marked as deleted.

How can I clear Zope Recycle bin?

You go to Control Panel, and then Database, aand press the purge button.

And how I can modify manage_beforeDelete func to cancel del-operation(click on Delete button)?

You can't. Or at least, you don't want to. If you want a confirmation screen, it should appeare before the object is deleted.
