摘要
针对目前焦化厂生化脱酚废水的化学需氧量(COD值)普遍超标现象进行研究,采用焦化厂自产的熄焦粉经活化后吸附处理焦化厂生化废水,或采用活化熄焦粉与微生物活性污泥联合曝气处理焦化废水,使焦化厂废水的化学需氧量达到国家一级排放标准。在某种程度上可以取代废水的三级处理,即取代废水的深度处理,有着潜在的巨大的社会效益和经济效益。
This paper introduces the research that the chemical oxygen demand in de-phenol effluent of coking plant commonly goes beyond the national standard. It uses the extinguishing coke powder that is made in the coke-oven to absorb the bio-chemical effluent or uses the active extinguishing coke powder and the animalcule active sludges to combine the aeration to dispose the coking wastewater. This method makes the COD in the coking plant biochemical effluent accord with the national standard. To some extents, this disposal method is able to replace the three-grade disposal of wastewater, that mean is to replace the further disposal of wastewater. This method has a potential and tremendous benefit to the society and economy.
