Using consequence analysis on some chlorine operation hazards and their possible effects on neighborhoods in central Taiwan

The applications of chlorine have been broadly used in many industrial products, such as bleaching agents, synthetic rubbers, plastics, disinfectants, iron chlorides, fire refractory materials, insecticides, and anti-freezers, etc. According to the Taiwan Environmental Protection Administration (TEPA), more than 30 thousand tons were used in the year 2000. In addition, there were more than 12 reported incidents from 2000 to 2003—mostly on using chlorine as disinfectants (five) and as process agents (four).

This study investigated 15 chlorine operation plants in central Taiwan. These chlorine usages included bleaching agents, disinfectants, iron chloride, synthesizing rubber plastics, and others. Thirteen plants were located in the industrial parks and two were in or near residential zones. The consequence analysis were used three different methods to analyze the worst-case scenarios (WCSs) and alternative release case scenarios (ACSs) in order to compare impact zones for applying various active and passive mitigation systems, such as confined space, scrubber, water-spray, and so no. For two plants in or near residential zones, multi-layers mitigation systems and operation limits should be implemented in order to enforce more stringent protection measures. However, there was no specific regulation for chlorine plants operated at different locations, such as industrial parks or residential zones. In order to reduce chemical accidents and their impacts on public safety, our results suggest that source mitigation/management and warning systems should be adopted simultaneously.

TiO2/PS/Fe3O4 光催化剂的低温制备及其光催化和磁回收性能

以聚苯乙烯(PS)包覆油酸修饰过的纳米Fe3O4为磁核,在低温(90℃)、中性(pH=7左右)条件下,制备了以PS为惰性隔离层的磁载TiO2光催化剂.用X射线衍射仪(XRD)、透射电子显微镜(TEM)、傅里叶红外分光光度计(FT-IR)、振动样品磁强计(VSM)对催化剂的物相组成、形貌、表面性质、磁学性质进行了表征.以苯酚为模拟污染物,考察了其光催化活性,以自制的磁回收装置,考察其回收特性.结果表明,低温制备的TiO2为锐钛矿结构,平均粒径为2～5 nm,催化剂TiO2/PS/Fe3O4[其中物质的量比为n(TiO2)∶n(St)∶n(Fe3O4)=60∶2.5∶1]具有结构完整的壳/壳/核结构,TiO2在PS/Fe3O4表面负载牢固;光催化降解苯酚遵循一级反应动力学方程,TiO2/PS/Fe3O4[n(TiO2)∶n(St)∶n(Fe3O4)=60∶2.5∶1]的反应速率常数K=0.025 8,与纯TiO2的活性接近(K=0.026 2);循环使用5次后,反应速率常数仅降低0.003 4.所制催化剂具有较强的磁感应强度,平均回收率可达到92%以上.该低温水解法制备的磁载TiO2光催化剂具有良好的应用前景.     

Iron and lead ion adsorption by microbial flocculants in synthetic wastewater and their related carbonate formation

Although microbial treatments of heavy metal ions in wastewater have been studied, the removal of these metals through incorporation into carbonate minerals has rarely been reported. To investigate the removal of Fe^3＋ and Pb^2＋, two representative metals in wastewater, through the precipitation of carbonate minerals by a microbial flocculant （MBF） produced by Bacillus mucilaginosus. MBF was added to synthetic wastewater containing different Fe^3＋ and Pb^2＋ concentrations, and the extent of flocculation was analyzed. CO2 was bubbled into the mixture of MBF and Fe^3＋/Pb^2＋ to initiate the reaction. The solid substrates were analyzed via X-ray diffraction, transmission electron microscopy and energy dispersive spectroscopy. The results showed that the removal efficiency decreased and the MBF adsorption capacity for metals increased with increasing heavy metal concentration. In the system containing MBF, metals （Fe^3＋ and Pb^2＋）, and CO2, the concentrated metals adsorbed onto the MBF combined with the dissolved CO2, resulting in oversaturation of metal carbonate minerals to form iron carbonate and lead carbonates. These results may be used in designing a method in which microbes can be utilized to combine CO2 with wastewater heavy metals to form carbonates, with the aim of mitigating environmental problems.
