摘要
以OPMSE仿真计算造纸污水中COD,BOD5,NH3-N排放质量浓度为研究对象,查询及调研清河流域典型造纸行业产生的污水中COD,BOD5,NH3-N质量浓度范围,通过OPM SE仿真计算,结果表明:置信水平为99%时,COD置信区间为(34.09,41.84),BOD5置信区间为(6.65,8.40),NH3-N置信区间为(6.28,7.34);最佳出水各指标为ρ(COD)=12.79 mg/L,ρ(BOD5)=2.62 mg/L,ρ(NH3-N)=3.33 mg/L,最差出水各指标为ρ(COD)=70.47 mg/L,ρ(BOD5)=14.51 mg/L,ρ(NH3-N)=10.22 mg/L.将仿真结果与现有排放标准对比,拟定造纸行业的污染物直接排放限值为ρ(COD)=45 mg/L,ρ(BOD5)=9 mg/L,ρ(NH3-N)=8 mg/L.
Through the simulation and calculation of object Petri net modeling and simulation environment (OPMSE) for the emission mass concentrations of COD, BOD5 and NHa-N in waste water from paper-making industry, the range of COD, BOD5 and NH3-N mass concentrations in typical paper-making industry were inquiried and investigated in Qinghe basin. The results show that when the confidence level is 99% , the confidence interval of COD is (34. 09, 41.84), the confidence interval of BOD5 is (6.65, 8.40), and the confidence interval of NH3-N is (6. 28, 7.34). The mass concentration of the optimum effluent is ρ(COD) = 12. 79 mg/L, ρ( BOD5 ) = 2.62 mg/L, ρ( NH3-N) = 3, 33 mg/L, while the mass concentrations of the worst effluent are ρ(COD) =70. 47 mg/L, ρ(BODs) = 14.51 mg/L, ρ(NH3-N) = 10. 22 mg/L. Then making a comparison between the emission standards and simulation results are got. The direct emission limits of the paper-making industry are ρ(COD) = 45 mg/L, ρ( BOD5 ) = 9 mg/L, ρ( NH3-N) = 8 mg/L.
