Embodiment Construction

[0020] After the dirty clothes are received in the washing and dyeing factory, they first enter the sealed disinfection cabinet, which is filled with sterilization gas made of 20% ethylene oxide and 80% carbon dioxide, and the clothes are sterilized before washing. Drain into the water tank, after sterilization inspection, send to the washing equipment, use the circulating water after sewage treatment for washing, and finally wash with tap water. The washed clothes are dried by a dry solar heat collector at 60°C, ironed, packed, cleaned and disinfected before leaving the factory.

[0021] The sewage discharged after washing first passes through the coarse grid to remove the larger floating matter, and the fine grid intercepts the fine floating matter. After the sand is removed in the grit chamber, the pretreatment before the biochemical treatment is carried out, and then it enters the biochemical reaction tank. When using, firstly spray the "FG21" liquid additive into the sewage w...

Abstract

The energy-saving sterilizing washing method suitable for washing and dyeing industry includes sterilizing clothing inside a sealed sterilizing cabinet; establishing biochemical washed waste water treating pond to treat waste water for reuse; washing clothing first with the regenerated water and then with tap water; and drying and finishing washed clothing in a solar drier. The present invention has the advantages of sterilizing clothing to avoid cross infection, saving water, saving electric power, and preventing environmental pollution caused by waste water.

Description

(1) Technical field [0001] The invention belongs to the improvement of laundry technology in the laundry and dyeing industry. In order to avoid cross-infection during the laundry washing process, a laundry technology that can not only disinfect but also save water and electricity, specifically a sterilization and energy-saving laundry method is used. (2) Background technology [0002] There are more than 1.18 million outlets in the laundry and dyeing industry in my country, with more than 3 million employees. However, traditional laundry technology pays more attention to the cleaning effect of washing and ignores the sterilization and disinfection of clothes. Due to the complex source of the laundry being washed, it is easy to cause cross-contamination during the washing process. Inspections by the Center for Disease Control found that the contamination of E. coli, Staphylococcus aureus, Pseudomonas aeruginosa and hepatitis B virus were 28%, 30%, 8.9% and 12.5% ​​of laundry after...
