废漂白粉的资源化利用技术研究

Study on the Utilization Technology of Waste Bleaching Powder

漂白粉是氢氯化钙、氧化钙、次氯酸钙的混合物,其主要成分是次氯酸钙。漂白粉的有效氯含量为30%~38%左右,漂白粉有氯臭味、化学性质极不稳定、吸湿性强、易受光、热、水等作用而分解,漂白粉属于危险化学品,其使用和处理过程都有严格的规定和要求,若将过期的废漂白粉进行资源化利用,将变废为宝,减少其处理、处置成本,是一种废漂白粉处理的最佳途径。

Bleaching powder is a mixture of calcium chloride,calcium oxide and calcium hypochlorite,the main component of which is calcium hypochlorite.The effective chlorine content of bleaching powder is about30%～38%.Bleach powder with chlorine odor,the chemical nature is very unstable,strong hygroscopicity,susceptible to light,heat,water and other decomposition.Bleaching powder is a dangerous chemical,its use and treatment processes have strict rules and requirements,if the expired waste bleach powder for resource utilization,will turn waste into treasure,reduce its handling and disposal costs,it is the best way to utilization the waste bleaching powder.
