First, chemical companies produce fire fighting water, characteristics and hazards



Fire fighting water produced: Frequent causes of chemical accidents prevention caught faux fur cushion

Chemical Equipment complex and diverse reactor complex, and often work in high temperature and pressure conditions. Various components of the material here, processing, storage, handling, transportation. Event Fire , Leading to the container and pipe rupture, the material will leak out. Leak out of the fire when fire fighting materials mixed with water, he incurs pollution.



Fire fighting water features:



Abstract: Songhua River Water Pollution An example, described the fire fighting chemical enterprise generation and water hazards, the proposed chemical enterprises attach importance to the fire fighting water to the collection and processing, made to prevent water pollution and use of fire fighting methods of collecting the proposed regulations increase of "fighting fire with water "of the content.



2005 1 13, China Oil PetroChina Jilin Petrochemical Company nitrobenzene distillation column double benzene plant exploded, killing eight people were killed and 60 wounded, 69.08 million yuan of direct economic losses, and triggered the Songhua River water pollution incident. Harbin city without water may be due to double-benzene factory upstream petrochemical company after an explosion, fire fighting water soluble toxic liquid into the Drain Road, into the Songhua River, caused by downstream pollution. After reading this story I could not help thinking, fire Accident Reports tend to the fire department rapid response and heroic fighting focus and are ignored.



1 fire fighting water output is not quantitative. As the fire fighting water is generated when the fire, so its actual consumption of water and fire and material when the amount of leakage, whereas the total amount is closely related with the severity of fire. When the fire in the early or relatively light, the total amount of small, resulting in less fire-fighting water also; when the fire relatively serious, the total amount of the large, fire fighting water also produce more; when the fire is extremely serious, fire control facilities within an enterprise can not meet the fire safety requirements, enterprises need to use an external fire facilities and fire fighting water produced at this time even more.



2 complex composition of pollutants in wastewater. Chemical enterprise wide range of products, chemical installations vary. Different chemical equipment, different process, the leakage when the fire broke different positions, fire fighting composition of contaminants in water are different. Leakage of different materials, fire fighting water in the concentration of pollutants will be very different.



3 reactants, catalysts are often explosive, corrosive, oxidizing, high pollution, toxic and difficult to decompose and so on.



Fire fighting water hazards:



Generated by the fire fighting water and features predictable, if not take measures to collect, fire fighting water will flow along the ground to water pipes, and then into rivers, lakes, groundwater, surface water polluted, endangering people's lives security, and even lead to conflicts between states (the Songhua River pollution incident between China and Russia had a negative impact). Therefore the fire fighting water collection and treatment is necessary.



2, fire fighting water collection and treatment



Songhua River pollution incident was the fire fighting water soluble toxic liquid into the sewer, into the Songhua River. The chemical companies need to start by sewage effluent Water Treatment Plant collection, treatment compliance before discharge. This shows that the chemical industry dereliction of duty or the responsible person Drainage system Design defects caused the sewage without the collection, processing direct discharge. Songhua River water pollution incident resulting from the major pollutants benzene, aniline and nitrobenzene and other organic matter, according to expert estimates, about 100 tons of benzene into the Songhua River water pollution.
