Abstract

The invention relates to a water treatment medicine, and concretely relates to a water treatment medicine for the in-situ generation of active iodine through utilizing persulfate and iodide ions. A problem of the rapid preparation of safe, healthy and reliable drinking water during the emergent water shortage in production and livings is solved in the invention. The ater treatment medicine for the in-situ generation of active iodine through utilizing persulfate and iodide ions is composed of iodide and persulfate. The active iodine generated by using the water treatment medicine for the in-situ generation of active iodine through utilizing persulfate and iodide ions has the advantages of high oxidizability, strong sterilization and disinfection capabilities, and good flocculation effect, and can realize the rapid and efficient preparation of drinking water. The water treatment medicine prepared in the invention can be used for the emergency treatment of natural water to rapidly prepare safe, healthy and reliable drinking water.

Description

technical field [0001] The present invention relates to water treatment chemicals. Background technique [0002] River water, stream water, well water, reservoir water and other unfiltered and disinfected water contain various organic pollutants, microorganisms, and zoonotic parasites that are harmful to humans to varying degrees. Drinking them directly may cause acute Gastroenteritis, typhoid, dysentery and parasitic infections and other diseases. In recent years, due to the increasing destruction of the ecological environment, water pollution has intensified, and the types of pollutants in natural water bodies have increased, let alone direct drinking. [0003] When encountering natural disasters, army field training, field construction, archaeology, exploration, exploration, etc., people often urgently need drinking water. At this time, it is particularly important to seek a technology that can use natural water sources to quickly produce potable water. However, it is d...
