People’s living standards are indeed improving, but water pollution has always existed. What is going on here? What is the cause of water pollution? This chapter water quality online monitoring instrument manufacturers to understand together with you about the causes of water pollution!
1.Water pollution caused by human production activities, of which the water pollution caused by industry is obvious. (For example, industrial wastewater contains many pollutants and complex components, which are not only difficult to purify but also difficult to treat in water.)
Industrial wastewater is an important factor of water pollution caused by industrial pollution, and it accounts for most of the pollutants discharged by industry. The pollutants contained will be strange because of different types of factories, even if it is the same type of engineering, the production process is different, the content of pollutants contained in it will be different. In addition to the wastewater discharged by industry will directly inject people into the water body to cause pollution, there is also solid waste and exhaust gas can cause water pollution.
2.Agricultural pollution, which is mainly due to cultivation or clearing of land, makes the land surface loose, and rains when the soil and terrain are not stable, resulting in a large amount of sediment flowing into the water, thereby increasing the suspended matter in the water.
In addition, nowadays, whether it is growing vegetables or rice, etc., the use of pesticides and fertilizers is very common. However, only a small amount of pesticides and fertilizers used will be absorbed, but most of them are still in the soil and floating in the atmosphere, and also through rainfall and surface runoff washing into the surface water and infiltration into the surface water to form pollution.
3.Urban pollution, there are not only many people in big cities, but also many kinds of domestic sewage, garbage and exhaust gas, which causes water pollution. But it mainly comes from domestic sewage, which is a mixture of various sewage generated in people’s lives(such as: sewage discharged from kitchens, bathrooms, toilets, etc.). Every drop of its sewage pollutes many times more bodies of water.
But otherwise, the situation deteriorates, and the relevant departments require major enterprises to install water quality online monitors at sewage discharge ports, which is a good performance!
