摘要
近几年焦化产业在云南省得到飞速的发展,同时也带来了较为突出的环境问题.生产中熄焦方式的不同对水环境影响不尽一致,本文以某焦化项目为例对湿熄焦和干熄焦两种熄焦方式的焦化废水对水环境的影响进行了对比分析,发现干熄焦时排放的焦化废水,将使水体中COD、挥发酚、氰化物、氨氮、石油类和硫化物的占标率提高3.7、8、4.5、70.2、5.4和39倍,干熄焦排放的焦化废水对水环境影响较大.
The coking industry has developped remarkably in Yunan province in recent years, however, it also brought relatively serious evironment problem. In production, the influences of different coke quenching methods on environment are different. As for its influence on water, wet quenching could decrease the discharge of water pollutant greatly. In the meanwhile, it has less influence on water environment. Take a coking enterprises in Yun- nan province for example, the pullutant discharged by dry quenching would change the function of the recipitent water from the case Ⅲ water to the Ⅳ,and the COD,volative phenol,cyanide,ammonia nitrogen,petroleum,sulfide will increase 3.7 ,8,4.5,70.2,5.4,39 times respectively. Therefore, dry quenching is not available in this project.
