Folding point plus chlorine disinfection experimental device

After the purification of water quality such as concrete, precipitation or clarification, and filtration, most of the suspended substances in the water have been removed, but there are still a cert--n amount of microorganisms, including the harmful pathogen bacteria that are harmful to the human body are still in the water. Disease microorganism.

There are many ways to disinfect the water. At present, more chlorine disinfection is used. This experiment is --med at the water sources of bacteria and ammonia nitrogen in water, and uses chlorine disinfection methods.

Through experiment hopes, the following goals are achieved:

1. Understand the basic principles of chlorine disinfection;

2. Master the calculation method of adding chlorine and chlorine amount;

3. Master the basic method of disinfection of chloride.

2. Experimental principle:

The following reactions occur after adding the chlorine gas and bleaching powder:

CL2+H2O o HOCL+HCL (16-1)

2CAOCL2-2H2O ⇌ 2HOCL+CA (OH) 2+CACL2 (16-2)

The disinfection effect is m--nly HOCL.

If there is no bacteria, ammonia, organic matter, and restore substances in the water, the chlorine in the water exists in the form of free chlorine, and the amount of residual chlorine is equal to the amount of chlorine.

Because organic matter and a considerable amount of ammonia nitride in the water, they are very unstable in nature, and chemical reactions often gradually transform into ammonia. Ammonia is free in the water or exists in the form of ammonia salt.

After the chlorine is added, the split ammonia produces "binding" chlorine, which also plays a disinfection effect. According to the content of ammonia in the water, the pH value and the amount of chlorine are added, the relationship between the amount of chlorine and the amount of residual chlorine will occur in four stages, that is, four sections
