Management of hazardous waste in Thailand: present situation and future prospects

 This paper deals with the present scenario of hazardous waste management practices in Thailand, and gives some insights into future prospects. Industrialization in Thailand has systematically increased the generation of hazardous waste. The total hazardous waste generated in 2001 was 1.65 million tons. It is estimated that over 300 million kg/year of hazardous waste is generated from nonindustrial, community sources (e.g., batteries, fluorescent lamps, cleansing chemicals, pesticides). No special facilities are available for handling these wastes. There are neither well-established systems for separation, storage, collection, and transportation, nor the effective enforcement of regulations related to hazardous wastes management generated from industrial or nonindustrial sectors. Therefore, because of a lack of treatment and disposal facilities, these wastes find their way into municipal wastewaters, public landfills, nearby dump sites, or waterways, raising serious environmental concern. Furthermore, Thailand does not have an integrated regulatory framework regarding the monitoring and management of hazardous materials and wastes. In addition to the absence of a national definition of hazardous wastes, limited funding has caused significant impediments to the effective management of hazardous waste. Thus, current waste management practices in Thailand present significant potential hazards to humans and the environment. The challenging issues of hazardous waste management in Thailand are not only related to a scarcity of financial resources (required for treatment and disposal facilities), but also to the fact that there has been no development of appropriate technology following the principles of waste minimization and sustainable development. A holistic approach to achieving effective hazardous waste management that integrates the efforts of all sectors, government, private, and community, is needed for the betterment of human health and the environment.

珠江三角洲经济区污水系统设计原则

分析了珠江三角洲经济区水环境现状；阐述了城市污水分散处理与集中处理的利弊；指出污水深度处理与回用是形成良性水循环的有效途径，更是经济可持续发展的必然要求；通过对已建排水系统存在问题的分析，探讨了珠江三角洲经济开发区污水系统的设计原则，认为污水系统规划要改变传统设计方法，应方便再生水回用，由经济、技术、地理等综合因素确定排水分区、污水厂厂址与数量，选择适合各排水区域水质水量的工艺流程，预留污水厂与再生水回用管线分期发展的空间，应优先选用国产污水处理设备，尽可能维持城市河涌自然生态。     

Heterogeneous water phase catalysis as an environmental application: a review

Catalytic water phase processes as an environmental application is a relatively novel subject with tremendous potential in the near future. This review of 120 references presents the wide scale of heterogeneous water phase applications studied mainly within past five years. Both oxidation and hydrogenation processes are included as well as TiO₂ assisted photocatalysis. According to the references, heterogeneous catalysis is developing rapidly. New bimetallic catalysts and supports with higher surface area have improved catalytic efficiency in both oxidation and hydrogenation processes. It also seems that study on use of some waste materials such as red mud as catalyst is a very progressive field. On the whole, the chemical aspects are pretty well known, but the catalyst durability, and in many cases activity as well, has to be improved.     

刍议多效蒸发处理含盐化工废水的进展

随着中国市场经济的发展,各种工业项目如雨后春笋般在中国各地兴起,随之而来的是给生态环境带来的巨大压力。化工项目一般都伴随着废水、废气、固废的产生。其中废水的排放尤其要引起重视,近年来国内很多研究人员都在研究含盐化工废水的回收利用。文中围绕多效蒸发处理含盐化工废水的技术工艺展开论述,对国内在多效蒸发技术方面的应用进展进行简要概述。     

利用粉煤灰中活性炭的吸附能力治理含铬废水

通过实验研究指出，运用粉煤灰可同时治理含铬废水中Cr(Ⅲ)和Cr(Ⅵ)。结果表明，粉煤灰用量、废液酸度、振荡时间和温度等均对铬的去除效果存在一定影响。研究揭示，在常温(15～35℃)下，当粉煤灰的掺人比例为1：650、含铬废液pH为4．0～5．5、接触时间为40min时，粉煤灰可同时治理含铬废水中Cr(Ⅲ)和Cr(Ⅵ)，其中Cr(Ⅵ)的去除率在88％左右，Cr(Ⅲ)的去除率可达99％以上。该方法工艺简单，成本低廉，效果优良，具有较好的应用前景。
