c, emptying the mixed cleaning solution cleaned in the fresh water cabin;
and step two, adopting a disinfectant to disinfect:
The method comprises the following steps:
2a, preparing a disinfectant, namely firstly, adding half cabin tap water into a fresh water cabin cleaned by cleaning fluid in the first step, then adding a high-chlorine disinfectant to prepare the disinfectant with the concentration of 0.03 g/L,
2b, sterilizing, continuously adding tap water until the fresh water cabin is full, sealing the cabin for sterilizing, and keeping the environmental temperature in the fresh water cabin above 15 ℃ for not more than 4 hours; keeping the temperature below 15 ℃ for no more than 8 hours,
2c, emptying the disinfectant in the fresh water cabin;
thirdly, washing by using tap water:
flushing the interior of the fresh water cabin at least twice by using tap water under the high pressure of 6.0MPa, emptying the tap water, finishing the disinfection and cleaning work of the fresh water cabin,
fourthly, detecting a cleaning result:
the fresh water cabin is filled with tap water, sampling and testing are carried out, and the detection result is as follows: the total dissolubility solid is 251mg/L, the total hardness is 130 mg/L, the nitrate nitrogen is 2.1 mg/L, the sulfate is 47.5mg/L, and the detergent is odorless and odorless.
the alkaline cleaning agent in the step a is an LAC alkaline cleaning agent.
The mass percentage content of the chloride ions of the high-chlorine disinfectant in the step 2a is more than 30%.
compared with the prior art, the invention has the beneficial effects that:
The scheme is simple and easy to implement, equipment is not required to be added, only the existing equipment is used for construction step by step according to a program flow, the process control is simple, the cleaning and disinfection efficiency can be effectively improved after the construction, and the requirements of cleaning and sanitation are easily met; the using amount of tap water is greatly reduced, the influence of discharged sewage on the environment can be effectively reduced while water resources are saved, the tap water is not required to be heated, the energy is saved, the construction cost is reduced, and the working environment of constructors is effectively improved; the scheme fills the application blank of the domestic ship industry, and provides precious experience for cleaning and chlorinating the fresh water tanks of other ships in the future, so that the scheme has pioneering use significance in the ship industry.
