Domestic sewage mainly comes from the wastewater discharged by residents in their daily lives, including sewage and sewage from places such as kitchens, bathrooms, and toilets. The pollutants can be divided into the following categories according to their forms:
Insoluble substances: accounting for about 40% of the total pollutants, including suspended solids, colloidal impurities, sediments, etc.
Dissolved substances: accounting for about 50% of the total pollutants, including inorganic salts (such as chlorides, sulfates, phosphates, etc.) and organic substances (such as cellulose, starch, sugars, fats, proteins, urea, etc.).
Aerobic pollutants: such as biochemical oxygen demand (BOD), chemical oxygen demand (COD), total oxygen demand, total organic carbon, etc.
Oil pollutants: including petroleum and animal and vegetable oils.
Biological pollutants: mainly refer to pathogenic microorganisms in wastewater, such as pathogenic bacteria, insect eggs, viruses, etc.
Nutritional pollutants: such as nitrogen, phosphorus, potassium, ammonium salts, etc.
Sensory pollutants: refer to substances in waste water that can cause discoloration, turbidity, foam, odor, etc
Domestic sewage contains a large amount of organic matter and pathogenic microorganisms. If discharged directly without treatment, it will cause serious harm to the environment and human health:
Pathogen pollution: Pathogenic microorganisms in domestic sewage have a large number, wide distribution, long survival time, and fast reproduction rate, which can easily enter the human body through various pathways and cause diseases.
Aerobic organic matter pollution: Organic matter in sewage, after entering the water body, will consume dissolved oxygen in the water, leading to deterioration of water quality.
Eutrophication pollution: Nutrients such as nitrogen and phosphorus in wastewater can cause eutrophication of water bodies, leading to massive algal growth and disrupting the ecological balance of water bodies.
Sensory pollution: the discoloration, turbidity, foam, odor and other substances in the sewage will affect the sensory quality of the water body and reduce the use value of the water body.
We are professional water treatment factory and can make the customized solution according to the sewage situation, provide the best and most economic solution for treatment.
