Remove bad dll reference after content data migration sharepoint 2007 - sharepoint 2010

I have 400 subsites under one root site and we need to remove one DLL reference from default.aspx Home page of each sub site.

Assmbly ref like this.

<%@ Register TagPrefix="WpNs0" Namespace="DS.DSQueryWebPart" Assembly="DS.DSQueryWebPart, Version=1.0.0.0, Culture=neutral, PublicKeyToken=709ed70a96eaa5cb"%>

This assmebly is not used anywhere .

This assembly is reflecting in subsite default.aspx after the content database migration sharepoint 2007 to sharepoint 2010.

Is there any way we can remove this bad reference through database query or any other way ar
