Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from. These can range from decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also incorporates a tertiary treatment stage with polishing processes and nutrient removal. Secondary treatment can reduce organic matter (measured as biological oxygen demand) from sewage, using aerobic or anaerobic biological processes.
Final Answer: The Answer is above.

Answer:
Sewage treatment plants can be used to remove the pollutants from sewage water.
Explanation:
Sewage treatment plant is a setup that contains majorly three treatments that are primary, secondary and tertiary treatment of sewage water. Under primary treatment, larger substances from the sewage water are removed passing it through a filtration slit. Then the remaining water is treated under a sedimentary tank (secondary treatment) with algae and fungi to remove the biodegradable waste. And at last water is treated with charcoal and chlorine through the remaining impurities are removed from the water. This is a widely used process to remove impurities from sewage water which makes water pollutant free.
