If you can build a humongous structure with dozens of cubic kilometers, larger
than anything that human beings have ever built, then you probably can also
build humongous air filters that will catch all the crap floating in the
atmosphere. Once a filter is full, it is replaced and the old one is burnt in
a solar furnace like all the rest of the waste. A similar treatment could be
applied to water.

As I always say, I think that life in a space colony will be maintained more
by industrial rather than ecosystemic/natural processes.

By the way, interestingly some big buildings on Earth are in some ways moving
toward a "space colony"-like architecture, with partial water recycling and
solar heaters...
