摘　　要：为配合中国石油吉林石化公司30万t/a乙烯工程A/O工艺废水处理工程化学污泥脱水的需要,进行了DYQ2000 XB型带式压滤机应用于化学污泥脱水生产性能力考核测试。确定了最佳带速、带张紧压力、投泥量、投药量和产泥量等指标,具有显著的经济和环境效益。在相同产泥量条件下,该带式压滤机比WL(F) 600Ⅱ型离心机年运行费用可节约58.86万元。The productive process of dewatering chemical sludge with belt filter press was applied and tested for the need of 300 kt/a ethylene plant in JiHua Company.The optimum belts velocity ,belts intensive pressures,inlet sludge, inlet flocculent and outlet sludge quantities were determined .Technological and economic indexes to be guaranteed were finished with higher economic and environmental profit.A great number of running fees can be saved by applying DYQ2000-XB model belt filter press instead of WL(F)-600Ⅱ model centrifuge in the condition of same outlet sludge quantities.
