摘　　要：介绍采用FAS-Jet供气式低压射流曝气系统的改良型氧化沟为核心的处理能力15000m3·d-1制浆造纸中段废水的工艺,并对整个调试运行过程进行了详细的介绍和分析。运行结果表明,该工艺设计合理,运行稳定可靠,出水CODCr≤150mg·L-1,SS≤80mg·L-1,BOD5≤80mg·L-1,去除率均大于85%,出水水质可达到造纸工业水污染物排放国家标准。An improved oxidation ditch process using forced air supply jet aeration system for pulp and paper making wastewater treatment were introduced, having a capability for 15 000m^3·d^-1, and an overall analysis and introduction was conducted for the whole commissioning of the plant. The running effect indicated that the process and the parameters were properly chosen, the system ran stably, and the quality of the outlet water was better than the requirement of discharged water standard for pulp and paper industry, outlet water CODcr≤ 150mg·L^-1, SS ≤ 80mg·L^-1, BOD5 ≤ 80mg·L^-1, removal rates of all of them are higher than 85%.
