2 Involves shredding, chuming, filtration and sedimentation
3 Does not require aeration
4 Involves microbial digestion of organic matter
Explanation:
Secondary treatment removes the dissolved organic matter by the use of biological agents and hence, known as biological treatment. This is achieved by microbes which can consume and degrade the organic matter converting it to carbon dioxide, water, and energy for their own growth and reproduction. This helps to reduce the \(\mathrm{BOD}\) of the sewage water.

The domestic sewage mixes with river water
1 Small animals like rats will die after drinking river water.
2 The increased microbial activity releases micronutrients such as iron.
3 The decreased microbial activity uses up dissolved oxygen.
4 The increased microbial activity uses up dissolved oxygen
Explanation:
The domestic sewage mixes with river water the increased microbial activity uses up dissolved oxygen

BOD refers to
1 Botanical oxygen demand
2 Biochemical oxygen demand
3 Bioreductive oxygen demand
4 Biological oxygen demand
Explanation:
BOD refers to Biochemical oxygen demand which acts as an indicator of the growing pollution in the marine environment.
