焦化废水生物处理技术研究

Biochemical Process for Treatment of Coke Plant Wastewater

采用PACT—硝化—-反硝化工艺,处理焦化废水。结果表明,排放水的COD可降至100 mg/l、NH_3-N浓度可达15mg/l,基本达到排放标准。该工艺适合于现有焦化厂废水处理设备的改造。

In this work, a treatment technology of PACT decarbonization nitrification-denitrification was studied for the coke plant wastewater, by which satisfactory removal of COD, ammonia nitrogen, nitrate and nitrite was achieved. This treatment scheme claims high flexibility, easy operation, and low investment, and particularly suits rectification to existing installations for treatment enhancement to meet increasingly demanding discharge standards.
