I have written the following program in Windows Store Apps.
CustomBinding b = new CustomBinding() ;
TextMessageEncodingBindingElement t = new TextMessageEncodingBindingElement();
HttpTransportBindingElement h = new HttpTransportBindingElement();
b.Elements.Add(t);
b.Elements.Add(h);
MyService client = new MyService(b, new EndpointAddress("http://localhost:8080/"));
var request = ...;
var response = client.Service000(request);
In Service000, request message is Utf-8 encoding, but response message is Mtom Encoding like following.

I want to process response message by MtomMwssageEncodeingBindingElement. But WinRT doesn't support MtomMwssageEncodeingBindingElement. Is there any way to process Mtom Enconding message?
Not easily. As you noted, the MTOM message encoding isn't supported by the WinRT .NET subset, so you cannot use it. If you control the service, you should consider adding a new endpoint with a binding that is supported by WinRT (such as BasicHttpBinding). If not, then you'd need to create a custom encoder which knows how to parse MTOM messages, which is not a trivial task.
