生物堆肥处理法削减有机固体废弃物中病原菌的研究进展

为解决有机固体废弃物问题,一些发达国家和发展中国家已经实施有机固体废弃物管理战略,如堆肥和蚯蚓堆肥。然而由于病原菌耐热突变体的存在,这些生物处理技术并不能完全削减有机废物中的病原微生物。已有研究表明,有机固体废弃物在堆肥处理后许多病原菌仍能存活。蚯蚓堆肥作为一种处理有机固体废弃物的新型技术可以显著降低堆肥体系中病原菌的丰度,是一种很有前景的卫生技术。本文阐述了有机固体废弃物堆肥处理后各种病原菌的削减状况及其潜在机理,旨在为实现有机固体废物的卫生处理提供理论依据。

Methods of financing such industrial development are discussed, and the effect of increased competition on the U.K. industry is considered. When the U.K. textile industry decides to get down to work and to think, plan and behave in a positive and co-operative fashion, it will be found that the new textile industries of developing countries need not be feared.     

Recent Development in the Role of Ozone in Water Purification and its Implications in Developing Countries

The recent discovery of chlorine-based halo–organic carcinogens in water supplies has highlighted the study of ozone as a suitable replacement to chlorine. Ozone is the most powerful oxidizing agent among water disinfectants. It has been used for water purification prior to chlorine and only its high cost has hampered its wider application. The recently discovered adverse effects of chlorine have buttresssed the use of ozone in water disinfection and today, over 1,100 water treatment plants around the world use ozone for disinfection. Large scale introduction of new disinfection systems in the developed countries will require suitable modifications in numerous existing water treatment plants. However, in the developing countries, the majority of the people do not yet have access to safe water supplies and the availability of plants which assure good quality water is ranked among the top priority targets in all national development programs in these countries.     

电子废弃物的生物代谢酸浸出(英文)

The revolution in information and communication technology has brought huge technical benefits and wealth,but has created a major global problem:the generation of vast amounts of electronic waste,or e-waste through product obsolesce.The challenge in managing e-waste will be in developing sustainable recycling technologies that are able to address the volume and complexity of this waste using cost effective and ecologically sensitive methods.In this study,the capability of microorganism metabolic acids in dissolving the metallic fractions from waste printed circuit boards was examined.Several factors were considered in the examination of the activity of the acids including secondary reactions,solution pH,temperature and the nature of ligands in solutions(or bioacid constituents).The leaching tests were conducted ex-situ,using synthetic organic acids.Leaching was performed for periods of up to 6 h at 70-90℃ and 1000 r·min-1.

A Novel Design of Crop Dryer for Use in Developing Countries

The dryer is required for drying of grain as well as drying of the processed products in small catchment agro processing centers in the developing world. However, due to varied material characteristics of grain and secondary processed product, two entirely different types of dryers are required. The grain is dried in a recirculatory dryer, whereas processed product is dried in a tray dryer, where it is frequently mixed and trays are also intermittently changed. To avoid the need for two dryers, a novel design of a low-cost hot air dryer was developed where just by changing the trays the dryer can be converted from an LSU grain dryer to a tray-type product dryer. The dryer was tested for drying soybean grain as well as processed soy products like blanched soybean dal and soyflakes. The capacity of the dryer was 100 kg/batch in a tray dryer with each tray accommodating 10 kg of wet material. In case of LSU mode, the capacity of the dryer was 250 kg of grain per batch. The drying time required was 5 h for 250 kg of wet soybean from 24 to 10% moisture content, whereas in a tray dryer 100 kg blanched soybean dal was dried from 60 to 10% in 5 h and 100 kg of soyflakes from 25% moisture content to 10% moisture in 1.75 h. The cost of the dryer is estimated at US$580.00 and it can be fabricated in a moderately equipped workshop in developing countries.
