Utilization of micro-electrolysis, up-flow anaerobic sludge bed, anoxic/oxic-activated sludge process, and biological aerated filter in penicillin G wastewater treatment

Desalination and Water Treatment (2014)

Yuanfeng Qi Shengbing He Suqing Wu Bibo Dai Changhua Hu

System which included micro-electrolysis (ME), up-flow anaerobic sludge bed (UASB), anoxic/oxic (A/O) activated sludge process and biological aerated filter (BAF) were investigated in penicillin G-processing wastewater treatment. The main quality of the wastewater was shown as follows: chemical oxygen demand (CODcr) of 1,4507–1,5280 mg L−1, ammonium nitrogen (NH3–N) of 598–826 mg L−1, suspended solid of 1,850–2,190 mg L−1, and pH of 3.5–5.2. Moreover, penicillin G residue in the wastewater was 130–150 mg L−1. ME was utilized as the pretreatment method, UASB and A/O process were designed for the secondary treatment, and BAF was used as the advanced treatment. The results revealed that biodegradability of the wastewater could be effectively improved by ME, and most of CODcr and NH3–N in the wastewater could be removed by UASB and A/O process, and the residual COD and NH3–N could be removed by BAF. The average COD and NH3–N in final effluent was about 275.3 and 19.8 mg L−1, respectively, and the treated wastewater quality reached the requirement of the national discharge standards (wastewater quality standards for discharging into municipal sewer pipelines, China, COD ≤ 300 mg L−1, NH3–N ≤ 25 mg L−1 in C standard). Especially, about 80% of penicillin G residue in the wastewater could be removed or converted by ME reactor, and the wastewater could be effectively deposed in this system.

Hydration process of RHA and SF in cement paste by means of isothermal calorimetry

CRC Press eBooks (2010)

Nguyễn Văn Tuấn G Ye Klaas van Breugel Ziye Guo Bibo Dai

Both Silica Fume (SF) and Rice Husk Ash (RHA) have been considered as “highly active pozzolans”. However, the activity of SF comes mostly from its particle size, but for RHA, mostly from its porous structure. So the effect of each material on cement hydration is different. The objective of this investigation is to study the effect of rice husk ash (RHA) and silica fume (SF) on portland cement hydration determined by isothermal calorimetry. The results confirm that RHA is a highly reactive pozzolan and in some mixtures well comparable with SF. The effect of RHA on cement hydration is observed particularly in the later period. The effect of RHA is most pronounced in mixtures with the lower water to binder ratio (wbr). Moreover, RHA seem to be more effective than SF at the higher curing temperature.

Secondary Development of a Nonlinear Creep Model Based on Fractional Derivative in FLAC3D

Zhilei He Bibo Dai

Time-dependent deformation behavior of rock has a significant impact on the stability of rock slopes or underground constructions, and more and more attention is paid to the research of creep models. Newton dashpots of burger-creep model in FLAC3D were replaced by abel dashpots. A nonlinear creep model was put forward based on fractional derivative. The finite difference scheme of the creep model was deduced for three-dimensional state. Using secondary development program interface of FLAC3D with the VC++, the program of user-defined model was developed. The reasonability and reliability of the model were verified by axial compression creep test of rock. The results show that the nonlinear model can describe the visco-elasticity, plasticity of rock. The research results promote the progress of secondary development of creep models and can provide references for similar models.

Energy characteristics and damage constitutive model of pre‐cracked granite with or without filling materials

Fatigue & Fracture of Engineering Materials & Structures (2024)

Tao Tan Chunyang Zhang Bibo Dai Yixian Wang

Abstract In order to study the effects of pre‐crack inclination angle and filling material on granite, uniaxial compression tests were performed on pre‐cracked granite specimens without filling material and specimens filled with epoxy resin, gypsum, and organosilicon. Results indicate that the peak strength and apparent stiffness of pre‐cracked granite without filling materials increase with increasing pre‐crack inclination angle. The strain energy absorbed by the filling material improves the energy storage limit, inhibits the energy release effect when microcracks are connected to each other, and ultimately improves the compressive resistance and energy storage capacity. The strengthening effect of gypsum and epoxy resin is relatively better, which is more significant when the pre‐crack inclination angle equals 0°–60°. Finally, a damage constitutive model is established, which is in good agreement with the test and numerical simulation data. The results can provide reference for the research of grouting reinforcement of rock masses.
