Published: October 2012

Phase separation of the poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester(PCBM) active layer (ATL) was investigated by varying their relative ratio in the organic solar cells (OSCs).With the help of the UV/visible spectrophotometer, optical microscopy and scanning electron microscope,we found that the cluster of PCBM at the interface or surface was affected by Al cathode, the composition of the blends and thermal annealing. The disc-like shape crystals of PCBM substituted for the needle-like ones at higher PCBM compositions at the ATL/Al interface, which led to stronger contacts and bigger contact area. It could make short circuit current density increase, but may affect the blend morphology and result in parallel resistance and open circuit voltage decreased with the PCBM ratio increasing from 40 to 60%. The microstructure of the P3HT:PCBM ATL, determined by the composition dependent phase separation, supported the optimized performance of the OSCs with the composition of 40–50% PCBM.

Published: October 2012

Other than silt density index (SDI), modified fouling index (MFI) is claimed as one of most useful fouling predictive tools in the practice of reverse osmosis. In this study, the effect of colloidal silica particles on the MFI value with the presence of crossflow sampler (CFS) cell at the upstream of MFI setup was systematically investigated. Colloidal silica with the particle size ranging from 70-100 nm was used as the model foulant in this experiment. The feed silica suspension was 0, 50, and 200 mg/L. The effect of membrane pore size as the test membrane in the dead-end cell on the fouling indices was also studied. Polyvinylidene fluoride (PVDF) membranes with molecular weight cut-offs of 150 and 100 kDa were employed. As predicted, the experiment results demonstrated that the fouling indices increased significantly as the feed silica concentration increased. The CFS-MFI values were always lower than the MFI in all the fouling index tests due to the shear force effect generated under the crossflow filtration mode. The fouling index generated from PVDF100 was higher than that of PVDF150 due to the retention of smaller particles. For this reason, PVDF100 membrane was preferred to be used as the test membrane for fouling index tests using colloidal silica over the PVDF150.

Published: October 2012

A full-scale nitrogen removal system composed of an anoxic tank, an anaerobic tank, a micro-aerobic tank and an aerobic tank (A2O2) was established to treat 15,000 t/d high strength ammonia wastewater of a nitrogenous fertilizer factory. After the first stage of commissioning test, the stable operation of short-cut nitrification and denitrification has been realized at the normal temperature. The results showed that under the conditions of COD/TN ratio of only 1~2, the average removal efficiency of COD、NH3-N and TN achieved 80%, 96% and 54%, respectively without extra addition of alkalinity or carbon source, and the effluent quality was better than the requirement of the《Synthetic ammonia industrial water contamination emission standard》(draft for comment). The variation of nitrogen compounds concentration and operational parameters of pH, DO were investigated in each tank of A2O2 system. The results showed that the short-cut nitrification was stabilized in the micro-aerobic tank through the control of DO concentration (about 0.6 mg/L). Although the pH of micro-aerobic tank was only 6.6 which inhibited the growth of nitrite bacteria, the nitrite accumulation ratio reached about 48 %, closing to the criteria for judgment of short-cut nitrification of 50%. During operation, the process parameters of the A2O2 system such as reflux ratio of the mixed liquids, sludge load, sludge concentration, sludge age and SVI were all maintained in normal range, and small fluctuation of process parameters didn’t show obvious influence on short-cut nitrification.

Published: October 2012

In this paper, we presented an approach to control on the total hardness over the wastewater treatment recycling process for pulp and paper mill. The main problem, however, is the effects of Ca2+ concentration on the recycling treatment process. The experiments were conducted by using coagulation method with reagents of Ca(OH)2 addition alone and Ca(OH)2 +PAC addition respectively to control on total hardness. The samples were collected from the effluent and the influent of the biological treatment tank respectively of the wastewater treatment plant in a pulp and paper mill. The experimental results identified that the optimum reagent addition position was in the effluent of the biological treatment tank. When addition Ca(OH)2 alone, the optimum Ca(OH)2 addition amount was 2g/L, as a result, 70.1% of total hardness was removed ( from 1088.05mg/L down to 325.16mg/L), pH value was from 7.23 to 8.61, and sludge volume ratio was 9.9%. When addition PAC+ Ca(OH)2 , the optimum Ca(OH)2 addition amount was 1g/L, the optimum PAC addition amount was 300mg/L respectively, as a result, 71% of total hardness was removed( from 1088.05mg/L down to 315.25 mg/L), pH value was from 7.23 to 7.66, and sludge volume ratio was 6.5%. The effluent-quality can meet the National Industrial Wastewater Recycling Standard on the total hardness of 450 mg/L requirement. The reagents of Ca(OH)2 +PAC had many advantages over Ca(OH)2 alone , such as less sludge quantity, high density of sludge, small volume of sludge, and less addition of reagents and so on.

Published: October 2012

In the research on urban climate, “heat island effect” is the key point, which directly affects the buildings of city, the traffic, and people's daily life.[1]One important performance of the "heat island effect" is that the bottom atmosphere environment temperature is high, especially the air temperature near the underlay surface, namely air temperature 1.5m high. In the thermal environment which influences people's living and working, air temperature 1.5m high is the most important and direct. [2] It rises mainly by the absorption of the long wave radiation reflected by the underlay surface. So the type of underlay has a very important influence to the air temperature 1.5m high. The underlay surface temperature and the air temperature 1.5m high have a certain grade correlation. This paper is written for the research on the correlation.

In order to investigate how the previously air conditioned exposure impacts thermal perception in semi-outdoor spaces, the controlled experiments were conducted, with a total of 36 undergraduates who participated as the subjects. Based on the controlled experiments, the impact of previous exposure temperature to air conditioning was examined. It was found that the previously air conditioned exposure temperature has impact on thermal perception in semi-outdoor spaces. Based on the experiments, it can be found that the impact of the air conditioned exposure temperature is not significant when the temperature difference between the air conditioned environments is about 2°C or 3°C. However, the impact of the air conditioned exposure temperature appears significant when the temperature difference between the air conditioned environments is up to 5°C.
