Reversed mining and reversed-reversed mining: the irrational context of geological disposal of nuclear waste     

A. J. van Loon   《Earth》2000,50(3-4):269-276

Man does not only extract material from the Earth but increasingly uses the underground for storage and disposal purposes. One of the materials that might be disposed of this way is high-level nuclear waste. The development of safe disposal procedures, the choice of suitable host rocks, and the design of underground facilities have taken much time and money, but commissions in several countries have presented reports showing that — and how — safe geological disposal will be possible in such a way that definite isolation from the biosphere is achieved. Political views have changed in the past few years, however, and there is a strong tendency now to require that the high-level waste disposed of will be retrievable. Considering the underlying arguments for isolation from the biosphere, and also considering waste policy in general, this provides an irrational context. The development of new procedures and the design of new disposal facilities that allow retrieval will take much time again. A consequence may be that the high-active, heat-generating nuclear waste will be stored temporarily for a much longer time than objectively desirable. The delay in disposal and the counterproductive requirement of retrievability are partly due to the fact that earth-science organisations have failed to communicate in the way they should, possibly fearing public (and financial) reactions if taking a position that is (was?) considered as politically incorrect. Such an attitude should not be maintained in modern society, which has the right to be informed reliably by the scientific community.  相似文献

The influence of hazardous liquid waste on the permeability of earthen liners   总被引：1，自引：0，他引：1  

K. Kayabalı  M. Mollamahmutoğlu 《Environmental Geology》2000,39(3-4):201-210

 Permeability and its susceptibility to changes with time or exposure to chemicals are major factors in selection of earthen liners for use in hazardous liquid-waste containment systems. Earthen liners often consist of mixtures including both granular soil and fine matrix. Six different solid mixtures were tested to investigate the influence of hazardous liquid waste on their permeability. The granular part of the mixtures included sand and crushed natural zeolite, whereas the matrix was composed of bentonite and microcement. Highly acidic solutions, bases, leather industry leachate and municipal waste leachate were used as permeants. Of the mixtures tested, only two mixtures performed well against the attack of chemicals. The testing method was the falling head system with the compaction mold permeameter. The period of experiments varied from two to eight weeks. Received: 24 September 1998 · Accepted: 5 January 1999  相似文献   

高放废物处置北山预选区地表岩体结构与岩体质量相关性及其应用研究     

宗自华  陈亮  陈强  魏云杰  王锡勇  王驹 《岩土力学》2013,34(Z1):279-284

岩体工程质量是影响高放废物地质处置（HLW）工程长期稳定性和安全性的关键因素,也是处置库场址比选的重要依据。在地表岩体节理调查统计的基础上,采用RMR(relative metabolic rate)分级方案,探讨北山高放废物处置预选区内以花岗岩为主体围岩的岩体质量与岩体结构的对应特征,建立结构面间距D与RMR岩体质量总评分值之间的定量关系,对北山预选区芨芨槽地表岩体质量分布进行研究。研究结果表明,RMR与D值的点群分布具有扇形发散的正相关特征,随D值的增大,RMR亦呈增长趋势,但低级序岩体结构与岩体质量比高级序岩体表现出更好的对应关系。研究认为,选用RMR与D的点群中心线对应的线性方程评价花岗岩候选区的岩体质量可达到快速评价岩体质量、查明各级岩体空间分布特征的目的,同时也便于对不同候选场区进行大范围岩体质量对比。分析结果显示,北山芨芨槽预选地段BS16钻孔周边3 km2范围内主要以Ⅰ、Ⅱ级岩体为主,岩体质量总体较好且分布相对较为均匀。  相似文献

为处理海上油田废弃钻井液,以我国海上油田广泛使用的有机正电胶钻井液为例,研究采用铁碳微电解-Fenton氧化处理工艺可行性.结果表明,废弃有机正电胶钻井液及其固液分离后的废水COD超过废水排放标准.优化铁碳微电解-Fenton氧化的适宜条件:微电解时间不低于3h;双氧水质量分数为0.5%,氧化时间为2h.铁碳微电解-Fenton氧化处理工艺对废弃钻井液废液COD有较明显的处理效果,但一轮次处理无法达到排放标准.铁碳微电解-Fenton氧化—次氯酸钠深度氧化以及多轮次铁碳微电解-Fenton氧化处理可以使固液分离后的废弃钻井液达到工业污水排放二级标准.  相似文献   

Landfill Leachate Treatment: A Case Study for Istanbul City     

Cevat Yaman  Huseyin Kurtulus Ozcan  Goksel Demir  Hatice Eser Okten  Senol Yildiz  Asli Coban  Vahit Balahorli 《洁净——土壤、空气、水》2012,40(7):706-711

One of the most important problems arising from landfilling solid wastes is the leachate which contains high amount of pollution. Discharge of leachate without treatment causes negative effects on environmental and public health. In this study, parameters of chemical oxygen demand (COD), total nitrogen (TN), ammonia nitrogen (NH₄‐N), and total phosphorus (TP) were examined in the samples taken from the influent and effluent of leachate treatment plant, where Odayeri landfill leachate is treated. Obtained results showed that the treatment plant, which consisted of preanoxic biological treatment system, ultrafiltration (UF) and nanofiltration (NF) units were operating with high efficiency. Among the examined parameters during study, COD, TN, NH₄‐N, and TP were found to be treated at the rate of 99, 94.5, 99, and 93.8%, respectively. Landfilling is increasing rapidly in the world and this consequently brings the need of leachate treatment facilities. Therefore, this study is considered to be a guide for construction and operation stages of proposed new treatment plants.  相似文献   

Investigation of the Possibility of Copper Removal from Industrial Leachate by Raw and Calcined Phosphogypsum: D‐Optimal and Taguchi Designs     

Başak Mesci  Nurdan Gamze Turan  Okan Ozgonenel 《洁净——土壤、空气、水》2012,40(8):850-855

In the present study, the removal of Cu(II) was evaluated by raw and calcined phosphogypsum (PG) as an industrial product. The role of experimental factors on the removal of Cu(II) was examined by using D‐optimal and Taguchi designs. The experimental factors and their related levels were selected as initial pH of 3–6–8, adsorbent content of 5, 10, and 25 g L^?1, contact time of 5, 10, and 20 min, and temperature of 20, 40, and 60°C. The results are evaluated by ANOVA test to extract important experimental factors and their levels. The performances of the suggested factorial designs were then compared and regression models that took into account the significant main and interaction effects were suggested. Taguchi design was found as a reliable solution with less number of experiments for adsorption studies with the optimized values. The resultant removal efficiency is calculated as 78.34%. The results revealed that calcined PG is an appropriate adsorbent for Cu(II) removal from leachate of industrial waste.  相似文献
