Results showed that the effluent quality was excellent, i.e. effluent COD less than 25 mg/L, BOD 5 under 5 mg/L, turbidity lower than 0 65 NTU, and colour less than 30 DT, and met with the reuse water standard of China. The removal rates of COD, BOD 5, colour, and turbidity were 92 4%, 98 4%, 74% and 98 9%, respectively. Constant flux operation mode was carried out in this study, and backwash was effective for reducing membrane fouling and maintaining constant flux. Membrane fouling had heavy impact on energy consumption. More attention should be paid on pipe selection and design for the sidestream MBR system, too.展开更多

Based on 513 questionnaires, it uses descriptive statistical analysis and binary logistic model to analyze the consumption and influencing factors of woolen products. The results indicated that residents in the middle region were more inclined to purchase woolen sweater compared to the residents in the east region. Urban residents were more inclined to purchase woolen sweater compared to the rural residents. Personal income,satisfaction degree of quality, and style have significant positive impact on whether residents purchase woolen sweater, and purchasing quantity of cotton sweater has significant negative impact on whether residents purchase woolen sweater.展开更多

This method uses a stochastic function to simulate fuzz on some types of wool textile. The wool yarns are simulated on the basis of Phong illumination model. In order to obtain a visual effect of the wool textile with fuzz, the light intensity of fuzz is synthesized as a color parameter in the Phong illumination model after the yams have been simulated. The model of woolen textile with fuzz can be built eventually.With synthesis mapping methods, user can choose his favorite fuzz density on the wool by controlling some appropriate parameters.展开更多
