Influencing mechanism of high solid concentration on anaerobic mono-digestion of sewage sludge without

Yuyao ZHANG,Huan LI,Can LIU,Yingchao CHENG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6,   Pages 1108-1116 doi: 10.1007/s11783-015-0806-x

Abstract: High-solids anaerobic digestion of sewage sludge was a promising process, but high solid concentration negatively influenced methane production. The influencing mechanism was systematically analyzed in this study through a series of static anaerobic digestion experiments at total solids (TS) contents of 3%–15%. The results showed that TS 6% was the boundary between low-solids and high-solids anaerobic digestion, and the accumulative methane yield decreased exponentially when TS increased from 6% to 15%. The performance of anaerobic digestion was directly determined by the efficiency of mass transfer, and the relation between methane yield and sludge diffusive coefficients was well described by a power function. Thus, the increasing TS resulted in an exponential increase in sludge viscosity but an exponential decrease in diffusive coefficient. The blocked mass transfer led to the accumulation of volatile fatty acids (VFAs) and free ammonia. Acetic metabolism was the main process, whereas butyric and propionic metabolisms occurred at the initial stage of high-solids anaerobic digestion. The concentration of VFAs reached the maximum at the initial stage, which were still lower than the threshold influencing methanogens. The concentration of free ammonia increased gradually, and the methanogenesis was inhibited when free ammonia nitrogen exceeded 50 mg·L . Consequently, the deterioration of high-solids anaerobic digestion was related to the blocked mass transfer and the resulting ammonia accumulation.

Study on load bearing characteristic of cast in situ DX group pile with numerical analysis

Zhang Qinglin,Chen Lihong

Strategic Study of CAE 2012, Volume 14, Issue 1,   Pages 51-59

Abstract:

This paper analyzes 4 types of group-pile which contains 4 piles with spacing 1.5D, 2D, 2.5D and 3D（D is diameter of the bearing plate）by numerical analysis, and draws some conclusions. The main conclusions are: group pile effect of DX pile increases sharply when pile spacing decreases；the bearing capacity of 3D spacing group-pile is 1.32 times larger than that of 1.5D spacing group-pile；effect coefficient of group-pile increases from 0.59 to 0.78 when spacing increases from 1.5D to 3D；the maximum value of settlement of soil among group-pile occurs between two bearing plates, and it decreases when the spacing of pile increases.

Numerical analysis on uplift bearing characteristic of cast in situ DX pile

Chen Lihong,Zhang Qinglin,Yuan Xiyu

Strategic Study of CAE 2012, Volume 14, Issue 1,   Pages 31-36

Abstract:

This paper analyzes DX single pile with 2 bearing plates on its resistance of uplift load by numerical analysis method. The parameters for analysis are drawn from lab test and verified by large scale loading test of DX piles. The Q-s curve and axial force of DX pile are obtained,and the conclusions based on the analysis are drawn.The uplift bearing capacity of DX single pile is about more than twice larger than that of the normal single pile and its bearing plates work out from the upper to the lower order, while when the bearing capacity reaches certain level, the lower plate will play a more important role.
