How to deal with the sewage from washing the refrigerator?

Every summer we need to take out the refrigerator at home and clean out the debris and stains inside. However, how to deal with the sewage generated during cleaning?

Step 1: Separation

Step 2: Treatment

Treatment of these sewage requires different methods according to different situations:

1. No chemical pollution

< p>If there is no chemical contamination in the refrigerator, the treatment process will be easier. It is treated in the sewage treatment station, and biological agents are added to filter and separate the water until it meets the discharge standards, and then it is discharged into the sewer.

2. Chemical pollution

If the refrigerator is contaminated with chemical substances, the sewage treatment needs to be more careful. Before processing, it is first necessary to confirm the type of contaminated substances and collect relevant safety knowledge. If necessary, a specialized processing company can be hired to handle it.
