中国化工园区雨排系统环境风险防控研究

雨排系统是化工园区重要的基础设施,如果没有建立有效的环境风险防控体系,污染物有可能通过园区雨排系统排入外环境,造成重大环境影响.目前,中国已出台的有关化工园区雨排系统环境风险防控的政策法规缺少强制性和统一性,监管标准缺失导致环保部门缺乏行之有效的监管手段,园区规划阶段协同机制的不健全也增加了后期监管的难度.鉴于目前中国化工园区雨排系统环境风险防控方面存在的问题,建议国家和地方加快监管标准出台,强化相关政策的落实,优化园区雨排系统,实施分类、分级管控,同时加强企业的监管.     

Toward a framework of environmental risk management for CO<Subscript>2</Subscript> geological storage in china: gaps and suggestions for future regulations

China encourages the demonstration of carbon capture and storage (CCS) projects. In an effort to identify gaps and provide suggestions for environmental risk management of carbon dioxide (CO₂) geological storage in China, this article presents a concise overview of potential health, safety and environmental (HSE) risks and environmental management regulations for CO₂ geological storage in Australia, Japan, the United States (USA), the European Union (EU), and the United Kingdom (UK). The environmental impact assessment (EIA) experience of Shenhua Ordos Coal-to-Liquid (CTL) Project and PetroChina Jilin Oil Field enhanced oil recovery (EOR) is subsequently analyzed in light of our field investigation, and gaps in current EIA guidelines that are applicable to CO₂ geological storage projects are identified. It is found that there are no specific environmental risk regulations suitable for CO₂ storage in China, and environmental risk management lags behind the development of CCS technology, which presents a challenge to demonstration enterprises in terms of assessing environmental risk. One major challenge is the overestimation or underestimation of this risk on the part of the enterprise, and another is a lack of applicable regulations for government sectors to supervise the risk throughout CCS projects. Therefore, there is a pressing need for China to formulate environmental management regulations that include environmental risk assessment, mandatory monitoring schemes, environmental emergency plans, and related issues.

坚持安全发展 推进综合监管——访国家安监总局副局长梁嘉琨

近年来，我国各级安全生产监管部门全面落实科学发展观，坚持安全发展的理念，认真履行安全生产综合监管职能，积极探索开展综合监管工作的措施、途径和手段，逐步构筑了“分类指导、职责明晰、条块结合、运行有序、机制完善”的安全生产综合监管机制和总体格局，全国安全生产综合监管建设取得了长足的进步。但是，在综合监管工作实践中，很多地区也都遇到并提出了同样的问题：《安全生产法》等法律法规中并没有对综合监管的内容作出明确的规定。

粉尘在巷道中的紊流传递分析

建立的粉尘在巷道中的传递方程是一个二维平流扩散输运方程。在巷道顶底板为吸收壁的条件下，导出了粉尘浓度分布函数。传统的工业沉降室沉降效率公式（横向混合模型）只是论文所列方程的一个特例。降低紊流强度和减小紊流扩散系数和纵向弥散系数均可提高沉降效率
