H2S can be a very dangerous compound - it can cause corrosion very rapidly in sewer networks, it causes odor in very small concentrations, and can even be deadly at high levels. The best way to control it is to prevent the development of H2S, either with oxygen injection upstream in the sewer lines, or with chemical dosing which can be very effective, but costly over the long term. Does your question refer more to collection networks or the treatment plant?

Hydrogen peroxide and other oxidants have been used to control hydrogen sulfide in the past. Adsorbents like zeolites or granular activated carbon might work. Calcium hydroxide scrubbers might also work.
