Systematic management for industrial waste in Japan has been carried out based on the Waste Disposal and Public Cleansing Law which was enacted in 1970. The law and its ordinances designate 19 kinds of waste materials discharged from business activities as industrial waste and prescribe the generator's responsibility, requirements for treatment contractors, standards for consignment, specific personnel, etc. from the view of proper management. And they also, prescribe disposal standards, structure, and maintenance standards for treatment facilities, including final disposal sites, from the view of proper treatment and disposal. The Standard for Verification provides criteria to categorize as hazardous or nonhazardous industrial waste which is subjected to treatment and disposal in conformity with each standard. The fundamental policies to cope with industrial waste focus on reduction of generation, promotion of recycling, establishment of a comprehensive information management system and participation of the public which can contribute well to prevent environmental pollution caused by inappropriate management of industrial waste. 相似文献

In The Netherlands, a small and densely populated country, the disposal of solid waste requires strict precautions. Because the landscape is flat and the watertable just under groundlevel, landfilling and dumping must be avoided as much as possible. Incineration of municipal and industrial waste are presently under consideration. But even when excellent flue gas cleaning systems are used, air pollution can present a problem, for instance, by dioxines produced during the process. For these reasons the government has published a waste disposal policy plan in which recycling, composting and prevention of waste production play a major role. Eventually about one third of the solid waste production will be incinerated or dumped. No solid waste will be exported. 相似文献

The disposal of industrial waste at sea is a subject which, justifiably, arouses a great deal of public interest. This paper presents the data from one aspect of a continuing, multi-disciplinary, programme which monitors the disposal of acid waste to a liquid waste disposal area. The benthic infaunal populations of both the disposal and a control area have been studied over a five-year period. The resulting data are analysed, using multi-variate techniques, and it is concluded that there is no evidence that disposal operations have altered the diversity or abundance of the benthic fauna. The distribution of the different faunal groupings within the areas appears to be related to sediment type. 相似文献

Hazardous wastes and economic risk reduction: case study, Poland 总被引:1,自引:0,他引:1
《国际环境与污染杂志》2011,7(2):221-248
A concise summary balance of industrial and hazardous waste is given, reflecting the situation in Poland. Nearly 130 million tonnes of waste were generated annually in the past in more than 1300 larger industrial plants. Approximately 1800 million tonnes of industrial waste is already stockpiled. The amount of hazardous waste generated per year was 0.3 and 1.0 million tonnes of the first and second class of toxicity, respectively. Seventeen existing on-site incinerators cannot treat the whole amount of solid and hazardous waste generated. Therefore, landfilling is still the most widely used method of waste disposal. Decontamination of the abandoned areas left by the Soviet Army, and reclamation of some hundreds of storage sites filled with outdated pesticides are now added to the national plan of waste management. Its implementation, including introduction of the best available and best managed technologies of hazardous waste treatment and disposal, will take at least 20 to 30 years. 相似文献

Small mammals were trapped, tagged and recaptured in 0.45 ha plots at six hazardous industrial waste disposal sites to determine if populations, body mass and age structures were different from paired control site plots. Low numbers of six species of small mammals were captured on industrial waste sites or control sites. Only populations of hispid cotton rats at industrial waste sites and control sites were large enough for comparisons. Overall population numbers, age structure, and body mass of adult male and female cotton rats were similar at industrial waste sites and control sites. Populations of small mammals (particularly hispid cotton rats) may not suffice as indicators of environments with hazardous industrial waste contamination. 相似文献

In response to a growing societal mandate, land disposal of hazardous wastes is gradually being replaced by treatment technologies. This shift to "alternative technologies" is the result of the impacts of past land disposal practices on other environmental media (groundwater, surface water, and air). A prime motivation for adopting alternatives to land disposal is to eliminate these cross-media impacts. Alternative technologies, however, can themselves have cross-media environmental impacts which must be recognized and addressed before such technologies are extensively applied. This paper discusses hazardous waste constituents, common disposal practices, alternative technologies currently being applied, possible cross-media environmental impacts of the alternative technologies, and proposed methods of mitigating these environmental impacts. Case studies from uncontrolled hazardous waste sites and industrial operations are used to illustrate the application of alternative technologies. Case studies include the application of waste treatment technologies as well as the adoption of waste minimization techniques. 相似文献

As part of a long-term environmental monitoring programme, PCBs and heavy metals have been determined on a monthly basis in soil and foliage samples collected from 13 sites, generally located within a 2 km radius of a hazardous and toxic waste disposal facility that has been operating for over ten years. Data are presented for a seven month period, from June 1984 to December 1984, and the results compared with normal worldwide background values given in the literature, and with some isolated U.K. samples. The comparison showed that no elevations indicative of industrial pollution had occurred. A statistical evaluation of the data indicated that there was no correlation suggestive of an airborne mode of transportation from a point source, with respect to distance from the plant or to the predominant wind vectors. The results confirm that the waste disposal facility has had no detrimental effect on the environment. 相似文献

Landfill and sea-dumping appear to be on their way out as acceptable methods for the disposal of untreated industrial wastes in Taiwan. Recently, there has been interest in the application of fluidized bed technology to waste incineration for efficient energy utilization and environmental protection. A pilot fluidized bed combustion system was used to investigate the incineration performance and parametric test for the waste from an industrial park. According to the experimental results, the appropriate operating conditions, including temperatures of 800-840 degrees C, aeration rates of U(0)/Um(f)-2.0 or so, and on-bed feeding, were recommended to treat such waste. The emissions of SO(x), NO(x) and CO in flue gas meet the ROC-EPA regulation. 相似文献

城市固体废物管理源头政策调控系统动力学模型 总被引:2,自引:0,他引:2
把城市居民固体废弃物源头调控政策、居民的废弃物分类行为与固体废弃物处置管理系统看成动态演化的反馈系统.在固体废弃物从量收费政策和法规政策影响下,采用系统动力学模型分析居民参与废弃物管理的行为对整个废弃物管理系统的动态影响.用开发的昆明城市同体废弃物系统动力学模型对3种设定的政策情景进行了仿真.结果表明:要实现同体废弃物处置与管理的可持续发展,必须在源头上通过收费和法规等政策促使居民参加到废弃物管理系统中,注重提高资源化和无害化能力的同时,要加强源头减量和回收的力度,减少废弃物的非法处置. 相似文献
