The average removal efficiency of TP and COD was 28.76% and 8% after cloth media filter without coagulation, and TP removal was influenced by the influent water quality. However, precoagulation with coagulants of ferric chloride, PAFC, PAC, the average removal efficiency of TP was 63.58%, 60.13% and 66.94% respectively, and no influence of TP removal can be found by the influent water quality. The average removal efficiency of COD was of 17.7%,26.3% and 27.7%,SS was 70.7%,64.3% and 49.1%.

当不投加混凝剂时，滤布滤池对TP和COD的平均去除率为28.76%和8%，其中TP的去除效果受进水水质影响较大；当投加氯化铁、聚合氯化铝铁与聚合氯化铝强化滤布滤池时，滤布滤池对TP的平均去除率分别为63.58%、60.13%和66.94%，TP去除效果受进水水质影响较小；对SS的平均去除率分别为70.7%、64.3%和49.1%；对COD平均去除率分别为17.7%、26.3%和27.7%。

Expression rate induced by thrombin was 50.88% and PAC?1 re?expression was 54.55%. It is concluded that the ability of recovered lyophilized platelets added with reversible activation?inhibitors, DMSO and trehalose to aggregate and coagulate has showed no significant difference as compared with FPRP. The reversible activation?inhibitors can decrease CD62p expression of lyophilized platelets, and may enhance their survival ability and prolongate survival time. Therefore the efficiency of lyophilizing platelets can be improved based on this freeze?drying procedure.

添加血小板可逆性激活抑制剂，海藻糖和DMSO后的冻干血小板，其聚集活性和促凝血功能与新鲜血小板无明显差异，血小板可逆性激活抑制剂降低了冻干血小板的CD62p表达，增强了冻干血小板的生存能力，因而延长了其生存时间，因此可以该冻干方法为基础进一步提高冻干保存血小板的效率。
