Problems solved by technology

[0002] Swimming pool disinfection generally adopts chemical agents, ultraviolet rays, ozone or metal ion disinfection methods, among which chemical agent disinfection has the disadvantages of poisonous disinfection reagents to the human body, narrow range of disinfection objects, and difficult to handle after disinfection;
[0003] Ultraviolet disinfection has the disadvantages of maintaining a certain water flow thickness for the disinfected swimming pool and high equipment maintenance costs after disinfection;
[0004] Ozone disinfection has the disadvantages of high power consumption of equipment, excessive use will cause human injury, ozone has poor treatment effect on algae and red nematodes, and needs to be synergistically reacted with chlorine-based agents;
[0005] Metal ion disinfection has the disadvantage of high disinfection cost
[0006] Therefore, the current routine is to use chemical disinfection, ultraviolet disinfection or ozone disinfection alone or in combination for disinfection, but for chemical disinfection and ozone disinfection, a large amount of organic auxiliary agents are added to facilitate the diffusion of disinfectants, and stabilizers are added. Make the disinfectant exist stably, while conventional organic auxiliary agents and stabilizers are extremely difficult to degrade. Therefore, considering the safety of the human body, it is generally necessary to change the water of the swimming pool twice or even three times after the disinfection is completed, resulting in a large amount of waste of swimming pool wastewater

preparation example Construction

[0053] According to another typical embodiment of the present invention, a preparation method of an easily degradable disinfectant is provided, the method comprising:

[0054] Add water to dissolve the active auxiliary agent, add wood carbon activated fiber, stir for 10-15 minutes, let stand for layering, centrifuge, stir again, and dry to obtain a mixed powder;

[0055] Add sodium calcium hypochlorite to the mixed powder, heat up and stir to obtain composite powder;

[0056] will RN x (OH) y (COOH) z Add it to the composite powder, let it stand, then add potassium hydrogen persulfate, stir until it is uniform, and obtain the hybrid powder;

[0057] Add iron salt to the obtained hybrid powder, stir evenly, then add diatomaceous earth, stir and disperse, and dry to obtain the powder of the disinfectant.

[0058] As an optional implementation, the temperature increase is to increase the temperature to 28-32°C at a rate of 1-3°C / s;

[0059] Control the temperature rise to a ...
