生物滤池处理生活垃圾恶臭

采用植物纤维性材料作为生物滤池滤料，接种人工培养的芽抱杆菌、酵母菌等14种不同的微生物。以NH3、H2S为检测指标，研究生物滤池脱除生活垃圾恶臭的可行性及其工艺，分析气体流量、进气总量和洗气装置对恶臭气体去率的影响。实验表明在维持一定恶臭气体进气浓度，气体流量Q≤48m3/h的情况下，生物滤池对恶臭气体具有较高的去除率；对滤料中微生物的分析表明，酵母菌、乳酸菌是生活垃圾脱臭的主要功能菌。

城市生活垃圾与煤流化床混烧过程中氮氧化物排放研究

针对我国城市生活垃圾热值低等特性。在流化装置上进行了城市生活垃圾与煤混燃实验，研究了在混燃过程中城市生活垃圾与煤掺烧比例及床层温度变化对NO和N2O排放浓度的影响。实验结果显示，随掺烧垃圾量逐渐增加时，NO排放浓度降低。而N2O排放浓度先降低然后增加，当城市生活垃圾与煤掺烧比例恒定时，随床温的增加NO排放浓度增加，N2O排放浓度呈下降趋势，采用前向式神经网络，以掺烧比和床温作为输入参数，对NO的排放进行预测。结果显示精度较高。

Impediments to refractory recycling decision-making

This paper focuses on organizational impediments to the successful implementation of industrial recycling programs. Even if a technologically viable and mutually beneficial solution were to exist, there are a number of organizational impediments that make it unlikely to succeed unless the benefits are very large and apparent. These impediments stem from the difficulty in identifying potential partners and involving the appropriate individuals within the firms that understand the technical requirements, value the strategic benefits and are receptive towards establishing the industrial recycling relationship. This dilemma applies to many industrial recycling opportunities, but solutions do exist. One way to avoid some of these obstacles is to use a middleman, or broker, who can play several crucial roles to establish the relationship. This paper describes the impediments and key broker roles, and provides a case study dealing with refractory recycling. It provides a case study that documents a recycling relationship between an aluminum-manufacturing firm that produces a large volume of spent refractories and a regional portland cement producer that is using the spent refractories as an alternative raw material source. This paper also provides a thorough literature search in the area of refractory recycling. Finally, the case study provides an opportunity for analysis and reflection on the implications of these findings to industrial firms, industrial societies and governmental agencies that seek to encourage successful recycling operations.     

Modification of Soy Protein Plastic with Functional Monomer with Reactive Extrusion

Chemical modification of soy protein with monomers such as maleic anhydride, glycidyl methacrylate and styrene was accomplished using reactive extrusion technology. Thermal and mechanical properties of the modified soy protein plastics were characterized with differential scanning calorimetry (DSC), a dynamic mechanical analyzer (DMA) and a United Testing System load frame. It was found that the denaturation temperature and the glass transition temperature of soy protein plastic changed. In addition, the tensile properties of modified soy protein plastic improved. Attenuated total reflection Fourier transform infrared (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) were used to characterize the structure of modified soy proteins. A suggestion of the interaction between soy protein and functional group in functional polymers is given. Through the in-situ interaction between the polymer and soy protein plastic, the mechanical properties of the soy protein plastic can be adjusted and controlled.
