There are various sources of water pollution, which can cause water pollution problems in human production and life. If industrial wastewater, medical wastewater, domestic sewage and the like are discharged directly without treatment, it is very likely to cause water source pollution. Let’s take a detailed look at the causes of water pollution below.

1.Industrial wastewater is an important cause of water pollution. This wastewater contains various pollutants. Once directly injected into water bodies, it will cause pollution.

2.Agricultural pollution: In agriculture, due to farming or land reclamation, the surface of the land becomes loose. If rainfall occurs before the good soil and terrain have stabilized, a large amount of sediment will flow into the water, which will lead to an increase in suspended solids in the water exceeding the standard and cause pollution. For agriculture, there is another important reason, which is that more and more chemical fertilizers and pesticides are used. Only a small amount of them will be attached and absorbed, while the majority float in the atmosphere and remain in the soil. If there is rainfall, they will be washed into the surface water by surface runoff, thus causing pollution.

3.Urban pollution sources: In cities where the population is relatively concentrated, urban domestic sewage, garbage and waste gas can all cause water pollution. It is mainly domestic sewage, which is a mixture of various types of wastewater used in our daily life, including sewage discharged from kitchens, toilets, etc.

4.Pollution caused by medical wastewater: Compared with other types of sewage, medical wastewater is more complex, containing a large amount of viruses and bacteria, etc. The discharge of medical wastewater causes great harm to water resources and is one of the main “sources” that endanger the public. If medical wastewater containing pathogenic microorganisms is discharged directly, it will cause water pollution. In severe cases, it may lead to various diseases.

Here is a brief summary. To ensure that water bodies are not polluted, all major enterprises must do a good job in water quality monitoring. Just like industrial process water monitoring, industrial wastewater monitoring, urban sewage monitoring, online monitoring of medical wastewater, etc. Remember! These sewage and wastewater cannot be discharged directly. They must be treated and monitored, and all pollutant indicators must be qualified. Only then can they be discharged with peace of mind!
