As one of the responses above, I would suggest covering the odor sources and venting to a biofilter. Assuming the major sources are the headworks and dewatering should be fairly easy to accomplish. The activated sludge process should not be causing odors if it is healthy. Be very careful if you consider adding chemicals to avoid killing off the activated sludge biomass.
