摘　　要：针对南山煤矿矿井水流化床净化工艺中存在的PAM配制与投加、流化床运行方式及高岭土加药点不当等问题进行了分析讨论,并提出了相应的改进措施。处理系统调试中,将PAM配制浓度提高至0.5‰,开启了流化床搅拌桨,并延长了排泥周期,缩短了排泥时间。通过上述改造,造粒流化床工艺处理负荷达到16.2m/h,产水量增加了1000m3/d左右,且对于33%的冲击负荷具备了较强的耐受性。调试结果说明,造粒流化床用于南山煤矿矿井水处理,具有处理负荷高,自用水量小,抗冲击负荷能力强等优点。The existing issues among the operation of pellet fluidized bed （PFB） process used on coal mine water purification in Nanshan Colliery, such as making up and dosing of polyacrylamide （ PAM）, the operation of PFB and the dosing point of Kaolin were analyzed, corresponding solutions were put forward. During debugging of the system, the concentration of PAM was increased to 0.5%0, the agitating valve was switched on, the sludge discharge cycle was extended and the sludge discharge time was shortened. The surface load of the PFB process was enhanced to 16.2 m/h, and could endure 33% hydraulic loading, the effluent was increased about 1 000 m3/d. The experimental results indicated that the PFB process used in coal mine water purification was characterized by high surface loading, low water consumption rate, and satisfied adoption of shock loading.
