Diatom Algae to consume Nitrate
If you can build a small tank that gives at least 10 days retention time, i.e., tank size is 10 times the daily inflow of sewage, you can grow Diatom Algae in the tank. Diatoms will consume the Nitrate and produce Oxygen, so there will be no foul odor.
The tank can be covered with an acrylic sheet, that allows some sunlight to pass through since Diatoms require light for photosynthesis.
The overflow from the tank can be released into any pond or lake nearby, the fish in the pond will consume the Diatoms.
If you have space for a larger tank or pond, you can grow fish and benefit from sale of fish.
You would be aware that urine is an excellent fertilizer, so it can be used to grow fish, by growing Diatom Algae.
