[0002] Domestic sewage refers to sewage from residential life, commercial activities and general densely populated areas, including wastewater from washing, kitchen waste, bathroom, toilet discharge, etc. It contains various organic and inorganic substances, such as food residues, grease, detergents, chemicals, bacteria and viruses.

[0003] Therefore, the indicators for detecting domestic sewage usually include the following items: BOD (biochemical oxygen demand), which refers to the amount of oxygen required by microorganisms to use organic matter in water for respiration and biochemical oxidation at a certain temperature. A high BOD value usually indicates that the content of organic waste in the water is high, which may lead to eutrophication, hypoxia and other problems; COD (chemical oxygen demand), which refers to the amount of oxygen required for organic matter in water to undergo chemical oxidation reactions; SS (suspended solids), which refers to the content of suspended particulate matter in water, including sediment, suspended organic matter, etc.; TP (total phosphorus), which is a nutrient in water. Excessive total phosphorus content may lead to eutrophication of water. TN (total nitrogen), which is another important nutrient in water, comes from sewage discharge, agricultural wastewater, etc.; pH value, the acidity and alkalinity of water has an important impact on the living environment of aquatic organisms. Changes in pH value may lead to the release of toxic substances in water or the loss of biodiversity.
