Factors:
First, the presence of flammable substances.
Second, the concentration reaches up to the explosive limit.
Third, to reach the point of ignition.
Chemical and pesticide production enterprises of many varieties, wastewater quality complex.
The main features include: high concentration of pollutants, COD (chemical oxygen demand) up to tens of thousands of milligrams per liter.
In addition to pesticides and intermediates, wastewater also contains toxic substances such as phenol, arsenic, mercury and many biodegradable substances, accompanied by bad odor.
In the process of wastewater treatment, the combustible gas produced by anaerobic, mixed with organic gases such as benzene and aniline volatilized in the wastewater, may explode if not handled properly.
Influences:
First, the explosion process may generate toxic and harmful gases, will affect the quality of the surrounding air environment.
Second, the explosion disposal process containing pollutants in the fire tailwater may enter the surrounding water bodies, secondary water environmental pollution.
Third, a large amount of solid waste generated after the explosion, may be part of the hazardous waste, need to be properly disposed of.
