Abstract

Thermophilic oxic process was applied to treat the dredged sedimentary mud of lakes and river which contain approximately 15% of organic materials. Organic wastes such as waste food oil and rice bran were added as an energy source. Cedar chips were added as a media to adjust moisture content. Physical and chemical characteristics of mixture after the treatment of thermophilic oxic process indicate that it became a good soil conditioner for growth of the plants. Compared with conventional natural land drying and dumping disposal method, it can save space and time, prevents odor production, make no worrisome about secondary pollution to environments.
