| Abstract: | With the development of wastewater treatment, the processing and disposal of the sludge which produced from wastewater treatment plant are arising more and more attention. A sludge digestion technology-ATAD ( autothermal thermophilic aerobic digestion)is introduced in the paper. ATAD decompose the organic matter to stabilize sludge, and accomplish a high degree of pathogen reduction. The digested sludge is turned into a stable and hygienic product. The hygienic quality of the product satisfies the pathogen criteria for farmland usage.As a result of high operation temperature, it has high efficiency and requires small volume. Furthermore, the operation of ATAD is relatively simple. The processing theory and flow, reactor structure and effect factors are discussed in this paper. |
