The pollution of urban rivers is severe, and the deterioration of water environment has seriously affected the normal development of cities. Moreover, if water pollution is not treated, it poses certain threats to the ecological environment and human health. So what we need to do is to try our best to prevent tragedies from happening. In this chapter, the manufacturer of online water quality monitoring instruments will help everyone understand the sources of pollution in urban rivers and how to act!
Urban river pollution mainly comes from aspects such as daily life, industry, agriculture and rainwater. The following is a simple analysis of these four points:
1.Domestic sewage, simply put, is the water we have used in our daily lives, such as the water discharged from schools, hospitals, residences, public places, etc. As the population of cities is constantly increasing, it means that the discharge of domestic sewage will also rise accordingly. If the treatment rate and discharge of these wastewater are not synchronized, a large amount of domestic sewage will flow into urban rivers, seriously affecting water quality and damaging the ecological environment, etc.
2.Industrial wastewater can be regarded as the main source of pollution in urban rivers. It mainly comes from the drainage of industries such as papermaking, chemical industry and mining. Besides containing a large amount of organic matter, these wastewaters also have some toxic heavy metals and pollutants. If they are directly discharged into water bodies without treatment, it will cause harm to the ecological environment. However, nowadays, relevant departments are paying more and more attention to water quality safety. At the same time, they will require such enterprises to install water quality detectorsto monitor the changes in water quality in real time. There has been a great progress!
3.Agricultural wastewater mainly comes from animal husbandry, such as livestock and poultry breeding. If the manure is discharged directly without safe treatment, it will cause nitrogen and phosphorus pollution. In addition, the use of pesticides and fertilizers for growing vegetables and other plants will also cause pollution to rivers. If it is directly discharged into urban rivers without treatment, it will also seriously pollute the water quality of urban rivers.
4.Rainwater pollution: After the initial rainwater washes away the atmosphere, it then erodes roads, construction stations and waste, etc. These all contain some pollutants such as heavy metals and organic matter. The runoff into water bodies will aggravate the pollution of urban river water.
Of course, to ensure the safety of water quality, monitoring the treatment of sewage is indispensable! The equipment installed in different industries may vary. It can be determined according to the requirements of the local environmental protection bureau!
