摘要
某卷烟厂采用生物接触氧化结合气浮法处理卷烟综合废水,经过3年的运行实践表明,工艺运行稳定可靠,在进水COD为300～1500mg/L、SS为100～600mg/L、BOD5为100～900mg/L、NH3N为10～20mg/L、水温为20～30℃时,出水COD<70mg/L、BOD5<20mg/L、SS<30mg/L、NH3N<3mg/L,完全实现达标排放。
In some cgarette mill, a biological contact oxidation and air flotation wastewater treatment system with 1 440 m^2/d of treatment capacity has been used. It is indicated by three years operation that the process features a stable running and a high treating efficiency. Under the condition of influent COD 300 - 1 500 mg/L, SS 100 600mg/L,BOD5 100-900 mg/L,NH3-N 10-20 mg/L,temperature 20-30 ℃, the process produces an effluent with COD〈70 mg/L,BOD〈20 mg/L,SS〈30 mg/L and NH3-N〈3 mg/L.
