First, read the English article below.

For example, if you have a leaky pipe, make sure you get that fixed. Or, if you find a pest problem, deal with it as soon as possible. Call in a professional if there is still an odor, but you can’t identify the source. Dehumidifiers can be bought at home improvement stores and at some supermarkets. A dehumidifier will prevent excess moisture in your basement. A dry environment in your basement will keep mold and mildew from forming. A ceiling fan can also keep your basement from retaining too much moisture. If possible, install a ceiling fan into your basement. If the basement is very large, install a couple of ceiling fans. Run the ceiling fans for a few hours a day and while you are in the basement. A few odor absorbers to choose from are baking soda, cat litter, and charcoal briquettes. Choose a bucket or large container and fill about half of it with the absorber of your choice. You can use multiple buckets if you wish. Leave the bucket in your basement, and replace it once a month to reduce mildew problems. If your basement is not connected to your air conditioning system, it would be a good idea to do so. Adding a ventilation system will keep the humidity out of your basement. Keep in mind, however, that adding your basement to the ventilation system will likely be costly.
