脉冲电晕放电治疗有机废气的研究—放电反应器结构

对脉冲电晕法治理甲苯有机废气进行了实验，考察了放电反应器结构及参数对其性能的影响。结果表明，对线－筒式反应器，当直径较小时，去除率较高，但易发生火花放电，实验条件下直径２０ｍｍ的反应器效果较好。若采用陶瓷管反应器，其效果较金属管明显提高，脉冲峰值电压Ｖｐ为４２ｋＶ时，可使甲苯的去除率由４０％提高到６１％左右。对线－板式反应器，放电间隙越大，甲苯的去除率越低，使用陶瓷板反应器可使甲苯去除率明显提高，

Effect of Cross-Linking Waste Protein with Dialdehydes on Its Biodegradation Under Anaerobic Conditions

Most native polymers used in processing and application technologies are admittedly disposable from the environment in a biologic manner, but products possess low mechanical strength. One of the paths to increasing this attribute (if feasible) is their cross-linking, which may, however, affect their readiness to biodegradation. In the presented work this condition was observed on the example of waste protein (Hykol B) cross-linking by means of glutardialdehyde and glyoxal. Degree and course of cross-linking were determined through impedance spectroscopy. The objective of this work also was to obtain data for constructing a sensor capable of following the cross-linking course in real time, for potential industrial application of Hykol in continuous production. Impedance spectroscopy proved to be applicable even to this kind of material marked by considerable water content and exhibiting relatively high electric conductivity; so far it had been used only for materials of low conductivity. An aqueous environment inoculated with digested anaerobic sludge from a municipal wastewater treatment plant was selected for modeling anaerobic conditions. The relation was studied between cross-linking degree given by content of cross-linking agent (determined by impedance spectroscopy) and biodegradation degree under anaerobic conditions. It was confirmed that network density as given by quantity of added agent not only reduced breakdown degree but also slowed the course of the process. This fact is particularly obvious with cross-linking by means of glyoxal; network density is thus dependent on type of employed substance, which affect type and structure of created network. That not merely forms an obstacle during polymer swelling and dissolution but also prevents access of bacteria to source of metabolized organic carbon.
