What are the main sources of waste gas pollution from waste gas treatment projects?
2020-07-23
There must be exhaust gas before exhaust gas treatment. If there is no exhaust gas, there is no need for exhaust gas treatment. So,Waste gas treatment engineeringWhere does the main pollution come from?
1. Noise pollution
Sound pollution approaches or exceeds the permissible limits of human hearing. It will affect and change the normal physiological state of the human body, and even induce disease. It mainly comes from the operation of various machines in industry, transportation and other fields. Urban noise has become a major public hazard in the urban environment, the main noise sources are: industrial noise, traffic noise, construction noise and social noise.
2.Waste gas treatment engineeringsoil pollution
Pollutants generated by human activities enter the soil and accumulate to a certain extent, leading to soil degradation as a phenomenon, mainly from industrial and domestic wastewater and solid waste, pesticides and fertilizers, and atmospheric deposition.
3.Waste gas treatment engineeringpesticide pollution
Pollution of soil, water and air by pesticides and their degradation products. Mainly refers to organic chlorine, organic phosphorus and organic nitrogen pesticide pollution. Severe cases can lead to acute or chronic poisoning of humans, animals and plants. Pesticides and their degradation products in the natural environment pollute the atmosphere, water and soil, destroy the ecosystem, and cause acute or chronic poisoning of humans, animals and plants.
Pesticides are also divided into organic pesticides and inorganic pesticides. Pollution is mainly caused by organochlorine pesticides, organophosphorus pesticides and organonitrogen pesticides. There are many reasons for pesticide pollution, such as long-term use of highly toxic and high-residue banned pesticides, or abuse of crops.
4. Chemical fertilizer pollution
Excessive application of chemical fertilizers can cause water, soil and air pollution. Nitrogen compounds not used by plants in time, if they exist in the form of NO3-N that cannot be adsorbed by soil colloids, will be transferred to the dense layer of the root system with the penetration of soil moisture, causing pollution.
It will lead to the eutrophication of rivers, lakes and inland seas; the soil is polluted and its physical properties deteriorate. Toxic components in food, feed and drinking water have increased. In order to prevent environmental pollution, the use of chemical fertilizers should be controlled and managed.
The above isWaste gas treatment engineeringThe main source of waste gas pollution, waste gas can be seen everywhere in our lives. In fact, exhaust gas is mainly caused by human activities and natural processes, causing pollutants to be discharged into the clean atmosphere, causing air pollution. Human activities, especially human production activities, are the main causes of air pollution.
