Biohydrogen production with simultaneous wastewater treatment was studied in continuous stirred-tank reactor (CSTR) using beet sugar wastewater as substrate. Aerobic activated sludge was used as parent inoculum to startup the bioreactor. The reactor started up under the condition of influent COD concentration 4000 mg/L, pH 7, HRT 8h and (35±1)¿, with a biomass of 6.09 g/L activated sludge in term of volatile suspended solid (VSS). The reactor demonstrated stable performance with respect to biogas production and substrate degradation after 28 days of operation. Subsequently, the reactor was operated at OLR of 18 kgCOD/m3•day by the 53th day. During this phase of stable operation, the reactor also showed a COD removal efficiency of 45% and a specific H2 production of 76.64L/kgVSS¿d in the system. Experimental data documented the feasibility of molecular H2 generation along with substrate degradation from beet sugar wastewater during the bioreactor operation.

This paper describes a laboratory study on ceramsite manufacture using electroplating sludge mixed with pulvized fly ash(PFA) and activated sludge. The extraction toxicity of electroplating sludge and the mixing scale of sintering materials were studied. An orthogonal test was conducted to select the best manufacturing conditions such as warm-up temperature, warm-up time, sintering temperature and sintering time. The test results reveal that the sintering temperature and sintering time are the two major effecting factors during the ceramsite preparation. The strongest ceramsite could be obtained at an optimal condition: the ratio of raw material scale at fly ash: electroplating sludge: activated sludge=85:10:5, warm-up temperature at 700¿, warm-up time at 15 minutes, sintering temperature at 1200¿, and sintering time at 30 minutes. The quality of the ceramsite produced at optimal condition complies with the referenced Chinese Standard (GB/T17431-1998). Accordingly, it can be concluded that the ceramsite made from electroplating sludge with fly ash and activated sludge is feasible and practicable. Comparing with traditional fly ash ceramsite methods, this method is considered to be more economic and effective in electroplating sludge safe disposal and fly ash ceramsites manufacturing.

This paper explores the inter-relationships between increased energy efficiency and other factors related to energy efficiency in economic system by using the causal-loop diagram which systematic dynamic method provided. Then, through establishing a computable general equilibrium model that considering the different industry departments with labor, capital and energy input, we measure the impact of increased energy efficiency on all production sectors. The results show that the economic output is quite different when energy efficiency grows, and both heavy industry and the construction industry get an obvious growing output, while agriculture, light industry, service industry and transportation industry have a little influence.

The paper briefly reviewed the methods of smoke control in a high-rise building fire accident and the research status of this topic. It shows that the stair enclosure, which is almost the only path for the building occupants to safely egress the building during a fire event in a high-rise building, plays a very important role in the performance based design of a high-rise building. Four fire scenarios of a stair enclosure, namely no measure, natural ventilation, pressurization and dilution, are simulated by FDS. The simulation results are compared and analysis to obtain the optimal solution. The further studies also address.

In order to separate droplets from the steam, a new type steam separator with high efficiency in power plant is presented. An experimental model is established for determining the structure parameters and critical velocity of steam separator. Fibreglass filtering method is used for measuring the Separation efficiency of steam separator. The results show that separation efficiency of the steam separator with collecting hooks is higher than that of without it. The plate length of the steam separator has almost no effect on the separation efficiency. The turning angle of the separator is at 54º, the plate spacing is at 20 mm and the critical velocity is at 5 m/s to improve the efficiency. The water film adhering on the plate wall will break when the gas velocity is more than the critical velocity. The separation efficiency decreases and secondary liquid entrainment increases significantly. Separation efficiency of steam separator is high when moisture content of inlet gas is less than 30 g/m3, however, it is low when moisture content of that is more than 50 g/m3. The optimum structure parameters and empirical formula of separation efficiency can be obtained from the experimental analysis. It is beneficial to the industrial design of steam separator in power plant.

The influences of containing water rate and Co3O4 content of the Co3O4-γ-Al2O3 /ATP desulphurizer on SO2 desulphurization capability were also studied. According to the experiments, when Co3O4 content is about 3%~5%, and containing water rate of the desulphurizer is 15wt%˜30wt%, the desulphurization adsorbent has good adsorptivity and good desulphurization ability as a catalysis agent. Its sulfur tolerance is 19.74%, which is superior than that of CuO-γ-Al2O3/ATP and CuO/γ-Al2O3 desulphurizers.

Accidental toxic gas leakage coming with large exploitation and production activities in the west mountainous area of China is calling for a precise environmental risk analysis method about the leakage and dispersion consequences over complex terrains. However, most studies use simplified models deal with flat terrain scenarios and cannot predict such complex phenomena. This article systematically presents a CFD based method for modelling toxic gas dispersion over complex terrain. First, use GIS data to generate CFD computation grid for complex terrain. Then, a three-step simulation strategy contains ambient wind farm construction, toxic gas leakage and dispersion has been presented. A case study of high sulfide natural gas accidental leakage and dispersion over a mountainous area of 7.2×4.5 km2 has also been carried out. The research demonstrates that the CFD approach of modelling toxic gas dispersion over complex terrain can predict dispersion and toxic consequences quantitatively. It can be widely used in problems concerned with environmental risk analysis over complex terrains.
