There was just a thread posted about a week ago called "Delete paragraphs in scanned books (S & R with regexes)" that covered a few examples of page number removal using regex:

Having page numbers mixed in the text is pretty impossible to distinguish from normal numbers... unless you can find some sort of pattern.
- You mentioned a space between numbers... does a long page number look the same?
- For example, page 201 -> "example 2 0 1 text"
- Is there always spacing between the individual numbers?
- If you look at the code itself using Calibre's Editor, is there any sort of pattern you can see?
- For example, is it small and bold while the surrounding text is normal size?
- Is the page number on its own line?
- Is the page number in its own span?
- [...]
Can't really help unless more examples given as well.
If the numbers all appear in the middle of the text, this might be a very hard problem... because it would be impossible to distinguish between normal numbers + page numbers.

Indeed. Did you scan/OCR this yourself? Maybe you could take care of the page number problem before/during the OCR step instead!
