The invention provides a layer-by-layer slow release water treatment agent for delaying sea water membrane pollution and a preparation method thereof, and relates to the technical field of slow release water treatment agents. The layer-by-layer slow release water treatment agent for delaying sea water membrane pollution consists of an adsorption agent inner layer, a coagulant aid covering layer and a flocculating agent outer layer, wherein inner layer adsorbing agents are powdery active carbon and diatomite; covering layer coagulant aids are polyacrylamide and poly dimethyl diallyl ammonium chloride; outer layer flocculating agents are iron type and aluminum type flocculating agents. The preparation method of the layer-by-layer slow release water treatment agent for delaying sea water membrane pollution comprises the following steps that the powdery active carbon and the diatomite are put into a pelleting machine to perform circumferential rotation; the diluted coagulant aid solution is added onto the rotating powdery active carbon and diatomite to perform covering; particles are formed; the flocculating agents are added and wrap the outermost layer of the particles; rotating and drying are performed. The flocculation, the coagulation aid, the adsorption and the dynamic membrane are integrated; the layer-by-layer slow release structure is used; cooperative and synergistic action is achieved; the membrane pollution resistance is reduced; the membrane pollution is delayed; the preparation process is simple; the operation is convenient; the application prospects are good.

The invention belongs to the technical field of pharmaceutical preparations, and particularly discloses a preparation process and product of paclitaxel freeze-dried powder. The preparation process of the paclitaxel freeze-dried powder has the advantages of simple route, low production cost, and easier and more convenient transportation and storage, and avoids adverse reactions caused by adding excipients. The prepared paclitaxel micelle freeze-dried powder has high stability in vitro, and a paclitaxel solution obtained through redissolution of the paclitaxel micelle freeze-dried powder remains stable at room temperature for more than 12 hours and meets the requirements of drug treatment. The paclitaxel freeze-dried powder has higher blood stability, smaller particle size, and is more likely to exert an ERP effect. The paclitaxel freeze-dried powder can be re-dissolved by use of an ordinary physiological saline or glucose injection, and thus the administration process is greatly simplified.
