Abstract

The invention discloses drinking water clarification disinfecting pills and a preparation method. The drinking water clarification disinfecting pills are prepared by the following steps of: mixing polyaluminium chloride, chitosan, anhydrous sodium sulfite and anhydrous sodium carbonate to obtain a first mixture; mixing the first mixture, resin powder and talcpowder; tabletting the mixture into an inner layer core by using a tablet machine; coating the inner layer core with solution of shell-lac ethanol; mixing sodium dichloro isocyanurate and the resin powder to obtain a second mixture; rolling the second mixture on the surface of the coated inner layer core by using a sugar coating machine; and spraying aqueous solution of ethanol on the pills to prepare the drinking water clarification disinfecting pills. The drinking water clarification disinfecting pills of the invention have the advantages of time-saving and convenient use, easy carrying, and excellent turbid water clarification effect. The microorganism index of water treated by the drinking water clarification disinfecting pills is accordant with the national drinking water standard and the drinking water clarification disinfecting pills are suitable for military personnel, fieldwork personnel and tourists to treat and use the field drinking water.

Description

technical field [0001] The invention relates to a drinking water clarification and disinfection pill, which belongs to the field of drinking water disinfection and purification. Background technique [0002] In the past, the reagents used to prepare drinking water in the field were divided into clarifiers and disinfectants. The packaging was complicated, the operation was cumbersome, time-consuming, and the content of available chlorine was high. Adequate safe and reliable drinking water cannot be rapidly provided in emergencies. The double-layer personal drinking water disinfection pill produced by Unit 59174 has the functions of rapid disinfection and removal of excess chlorine after disinfection. The outer layer of the product is sodium dichloroisocyanurate and bentonite, the inner layer is sodium sulfite and bentonite, and shellac ethanol solution is used to coat the inner and outer layers of the separated pellets. When in use, each disinfection pill can treat 1 liter ...
