Which chemicals can I use to reduce the bad odour from sewage treatment plant (STP) treated water?
The STP has a pond with 80 m3 capacity for storing treated water. Algae grow in it every 2 days and turn the water and the bottom of the pond green.
How can I solve the algae and odour problem?

Intrinsyx has plants that can be put into floating islands which can clean water and reduce odour and algae as a result.

Pramod,
You could cover the pond with a floating reservoir cover. Many companies install these on a contract basis.

I believe you are asking the wrong question. Chemicals got you into this situation. Adding more chemicals, time, money is certainly not the answer. If you follow the established parameters of the Archaea RNA microbial life forms they WILL eliminate odor within an hour. The grey and or black water/sludge will be reduced into their elemental form which will 100% eliminate all pathogens and chelate any toxic substances into their nutritional state. At this point you will have the option of dumping clean potable water that is super charged with oxygen into a stream or return it to water storage tanks. Food and water shortages will disappear rapidly. The crops using the vitaminized recycled water will have a higher brix reading / nutrient dense. Sometimes using nature makes more sense than Dollars.

I believe you are ANSWERING the wrong question. I have no doubt that the Archaea systems you are trying to sell have their application, but please stop trying to shoehorn your sales pitch for Archaea into every question on this forum.
In any biological system, bacterial and Archaea populations will thrive or die-off according to the environmental conditions. Putting a biological organism into a non-ideal habitat where it is competing with other organisms will achieve no long term solution.

Dear Pramod,
I agree with Jeremy and Rick. The Odor Causing Bacteria are Anaerobic, if you leave the treated wastewater as it is in the storage tank, it will be septic and will give you bad odor which is your case.
To get rid of it, you may need to do Disinfection either by adding Sodium Hypochorite (NaOCl) or any other disinfectants, and / or you may aerate it to overcome anaerobic conditions.
If this is an open pond, you can make a fountain to beautify the pond as well as this will remove the septic conditions as the water will be in contact with air thus odor will be removed.

If the pond is for storing treated water and not for treatment of waste, you can feed chlorine or Sodium hypochlorite which will get rid of algae and odor.

Your title refers only to odour removal. If this is the main issue then the simplest solution is to aerate the pond. The odours are generally caused when the pond goes septic.
Are the algae really a problem too? If so, covering the pond will prevent light entering and allowing green algae to grow, though you might get non-photosynthetic things growing instead. Alternatively use a chemical disinfectant (chlorine, sodium hypochlorite, or similar) if the chemical residual in the water doesn't create a problem for water re-use. This will also help to prevent odour by eliminating the bacteria which cause it to turn septic, and the chemicals are oxidising agents too.
Attempting to control the algae by improving the performance of the STP is unlikely to be effective because algae only require trace concentrations of nutrients to grow; you might slow them down but you're unlikely to prevent growth altogether.

I feel that a part of the odor nuisance could be also caused by anaerobic conditions developing due to decaying algae if the treated effluent BOD is
