联合生物法处理炼油厂含油污泥的研究

大港石化公司采用联合生物法处理含油污泥,对使用好氧、厌氧工艺处理含油污泥的结果进行了探讨。实验结果表明:先进行好氧处理然后脱水再进行厌氧堆肥工艺处理含油污泥,除油率达到97.6%,除磷、钾的指标低于《城镇垃圾农用控制标准》(GB8172-87)的要求外,其他指标均符合该标准要求,且避免了二次污染。     

新西兰无过失伤害的预防、康复和赔偿体制介绍

新西兰意外赔偿局(ACC),是管理新西兰意外事件赔偿的政府机构。ACC计划是对在新西兰境内的公民、居民或临时来访的人提供受伤赔偿的服务。每年在复原、治疗和酬劳补偿等方面要花费十几亿元,为了保证这些服务,ACC从劳动者的薪金、燃油税、政府赞助和投资收入等方面来支付赔偿金,不同行业的工伤赔偿申请比率也不同。另外,ACC建立了培训基金,代替雇主负责对员工的安全与健康培训。虽然这一体制正面临一些私有化和费用不断增加的挑战和困难,但总体来说,ACC体制是适合新西兰的一个优良的方案,比其他国家的体制在管理效率和雇主利益等方面明显显示出优势。     

THE ROLE OF ADVISORY BOARDS IN A WATER MANAGEMENT AGENCY1

ABSTRACT: Since Saskatchewan assumed the responsibility for managing the Province's water resources in 1930, the importance of the Province's water resources has been recognized by assigning the responsibility for managing the resource to higher levels in the government structure. With such recognition, there tended to be an overlapping of responsibilities that resulted in undefined areas of jurisdiction and duplication of services. Also, there was no opportunity for direct public participation in the management structure. These deficiencies were recognized, and following a series of public hearings a “Cabinet Committee on Water Concerns” in 1983 concluded that the most appropriate government structure for managing the water resources of Saskatchewan would be a Crown corporation. As a result, in 1984 the Saskatchewan Water Corporation was formed and given the responsibility to manage, administer, develop, control, and protect the water and related land resources in Saskatchewan. An important aspect of this responsibility was that the corporation should initiate a process of public involvement. Thus, six “Regional Watershed Advisory Boards” were established. The Advisory Boards provide the Corporation with a linkage to the general public by providing advice, participating in policy revision and development, and assisting Corporation staff in other related water management activities.

Muting the Voice of the Local in the Age of the Global: How Communication Practices Compromised Public Participation in India's Allain Dunhangan Environmental Impact Assessment

Public participation is widely lauded as a way to make environmental decisions more democratic, to improve their quality, and to enhance their legitimacy. Scholars and citizens around the world repeatedly complain, however, that public participation frequently serves primarily as a pro forma exercise to defend predetermined decisions rather than as a meaningful opportunity for the affected public to influence decision-making. These critiques persist despite considerable research suggesting ways to improve the quality of public participation. This essay explores this problem by analyzing citizen involvement in the environmental impact assessment (EIA) processes for the Allain Duhangan hydropower project in northern India. It describes how meaningful public involvement was compromised—despite repeated objections by citizens and independent consultants—by four communication practices: (1) failing to provide adequate access to information; (2) predetermining EIA outcomes by controlling the definition of issues (“definitional hegemony”); (3) privileging scientific/technical discourse; (4) utilizing “consultative” forms of communication that promote one-way flows of information rather than more interactive forms that encourage the joint construction of information and values. This study further argues that these practices persist because they serve as acts of power that privilege dominant actors and interests in the larger socio-political context. This analysis thus suggests that altering communication practices that compromise the quality of public participation may require attending to the interaction between communication practices, relations of power, and the larger socio-political context in which public participation takes place.     

高浓度ABS树脂生产污水治理技术

ABS树脂生产装置中的污水处理一直是影响化工装置环保的一大难题。一方面,其废水水质差,悬浮物含量高,且多为细微颗粒,难以从水中分离,进入生化系统也难以去除;另一方面,污水中溶解性胶乳较多、粘性大,且为间歇式排放,对污水处理系统冲击较大。大庆石化总厂采取完善生产工艺操作过程、采用高效净水剂、对处理设备进行改进及对生产全过程进行污染控制等措施,并分阶段、分单元、分步骤地对污染源进行处理。采取这些措施后使ABS树脂生产中的废水得到了有效治理,处理后的ABS污水中CODcr含量在1000mg/L以下,悬浮物含量在500mg/L以下,石油类物质含量在30mg/L以下。处理装置的能耗、物耗也大幅度降低。     

反渗透膜法海水淡化技术在大连石化公司的应用

大连石化公司采用反渗透膜法海水淡化工艺为生产装置提供淡水资源,其用水取自炼化装置冷却换热后的海水,不额外增加海水的取用量,降低了成本。装置采用常规预处理加三级反渗透膜分离技术,同时配备了能量回收装置,将反渗透高压"浓水"的能量转换到低压的原海水中,使得能耗大大降低。文章介绍了该工艺的流程及其技术特点,该装置节能、节水,其产品水质量达到甚至超过了中压锅炉补给水的要求。工程运行稳定,对沿海同类企业有借鉴意义。
