依靠科技治理药厂粉尘污染

辽源市亚东制药厂片剂生产车间包衣工序是粉尘污染较严重的环节。过去解决粉尘污染的方法是前端靠吸尘设施，末端粉尘靠风机排向户外，这种简易的处理方法，既污染了车间内环境又污染了车间外的大环境加之车间生产设备陈旧、生产工艺落后，粉尘及某些有害物质四处飞扬，直接损害了操作—人的身。C健康，厂区周围群众上访告状也时有发生，厂群关系比较紧张。粉尘的污染不但影响着厂区内外的环境，同时也造成了大量的能源与生产原辅材料的浪费，尤其是产品质量也受到一定程度的影响，因此直接影响着工厂的经济效益。粉尘污染，一直是该厂头痛…     

蔺草加工过程中粉尘污染控制对策分析

对蔺草加工过程中粉尘污染产生源头进行了系统分析，其中拔草工序为产生粉尘量最多的一个环节。对染土改性、改变固色工艺、改进除尘设备3种控制粉尘污染的技术途径进行了分析比较。认为通过对蔺草固色用染土进行改性，结合布置合理的除尘设施，可以在不改变现有固色工艺的基础上，使粉尘污染得到有效控制。随着对蔺草固色机理研究的深入和人们消费观念的转变，采用无染土、纯天然固色工艺将是控制蔺草加工过程粉尘污染的最佳途径之一。     

村办企业污染环境怎么办

编辑同志：最近,我们村新办了一个翻砂厂,厂子一开工生产,就喷出许多黑烟和粉尘,严重影响附近居民的生活环境。请问,对这种情况应当如何处理？宁夏中宁县：王国珍王国珍同志：我国法律明确规定,任何企事业单位和个人在建设和生产过程中,都必须充分注意防止对环境的污染和破坏;不准在城镇的上风向和居民居住区建设污染环境的企业。《中华人民共和国环境保护法》第２３条规定：“散发有害气体、粉尘的单位,要积极采取密闭的生产设备和生产工艺,并安装通风、吸尘和净化、回收设施。”另外,我国《大气污染防治法》第２７条也明文规定…     

萧山水泥厂治理粉尘效益好

萧山县水泥厂始建于1965年,当时是一家用半干法生产的小型半机械化立窑厂,工艺落后,设备简单,整个生产过程几乎没有收尘设施,作业场所空气尘浓度高达1613毫克/立方米。不仅厂区、车间到处粉尘飞扬,而且周围几公里的环境都受到污染,职工身体健康受到严重影响。在这种情况下,水泥厂领导下决心治理粉尘,他们主要抓了以下几项工作: 1、进行调查、了解污染程度。弄清了全厂共有大小扬尘点82处,烟囱26支,排气孔24个,同时对粉尘的浓度进行测试。 2、根据了解的情况,统筹安排治理。做到组织落实、经费落实、措施落实。实行厂部抓攻关项目、车间抓小改革项目、班组抓跑、冒、滴、漏的“三级管理”。

氮肥尿素造粒塔顶部出口及车间空气中粉尘的测定

一、前言尿素粉尘是一种无定型的微粒<带有一定量的游离氨>,造粒塔冷却固化空气带粉尘的量不应过大。粉尘量大,不仅造成尿素的大量浪费,而且还要污染环境,对周围的农作物、水体、鱼类、人体造成一定的危害。通过定期对尿素造粒塔顶部出口粉尘的测定,可以计算出尿素的损失量、考查工艺生产设备、改进工艺、监测环

立窑水泥厂粉尘综合治理

全国有立窑水泥厂近万家,大部分立窑水泥厂设备简陋,管理水平低,粉尘污染严重。据不完全统计,每年从立窑水泥厂排放的粉尘达１０００万吨以上,成为全国最大的粉尘排放原,浪费了资源,污染了环境;许多立窑水泥厂在设计中配备有除尘设备,投资不少,但由于技术方面的,除尘设备却不能正常运行,造成浪费。本文从技术的角度分析立窑水泥厂粉尘治理的原则、方法,以期给这些水泥厂提供技术帮助。     

除尘设备的选择与使用

人类在生产和消费活动中使用了燃料和生产原料,在燃料的燃烧和原料加工成产品的过程中将排出有害气体、粉尘和臭气。本来,燃烧生成的污染性气体、粉尘、臭气,经过地面上的植物和微生物的作用或海洋表面层的化学反应而使之还原,不致产生严重的危害。但是当在一定的区域内集中燃烧大量的燃料时,污染超过大自然的净化能力时则将造成对大气的污染和对人类的危害。

EFFICIENCY PROBLEMS FROM USER FEES IN MUNICIPAL WASTEWATER TREATMENT1

ABSTRACT: The Environmental Protection Agency administers a construction grant program to encourage abatement of wastewater pollution by sharing with municipalities the costs of wastewater treatment facilities. The enabling legislation (P.L. 92–500) specifies that EPA's cost share will be 75% of construction costs. It further requires municipalities to collect user fees from industrial users of the facilities to repay that part of the federal grant allocable to the treatment of industrial wastewater. The municipality must return half of the user fees collected to the U.S. Treasury; the municipality is allowed to retain the remaining half. Retention by municipalities of these user fees lowers their effective cost shares and results in the following consequences: (1) a bias for municipalities to select certain kinds of abatement techniques regardless of whether or not they are the least-cost techniques from the national perspective; (2) a bias for municipalities to select larger-than-optimal scales of abatement facilities; (3) a hidden federal subsidy to industry; and (4) grants that favor industrial communities. This article examines the legislative and regulatory requirements for user charges, derives the algebraic expressions for calculating the real federal, municipal, and industrial cost shares with user fees; computes municipal cost shares for selected values of the determinant factors; evaluates efficiency and other consequences of current user fee arrangements; and concludes that the efficiency distortions brought about by the impacts of user fees on cost sharing could be eliminated by requiring that all user fees collected from industry against the federal cost share be returned to the U.S. Treasury.     

INDUSTRY COMPLIANCE WITH STORM WATER POLLUTION PREVENTION REGULATIONS: THE CASE OF TRANSPORTATION INDUSTRY FACILITIES IN CALIFORNIA AND THE LOS ANGELES REGION1

ABSTRACT: Pollutants in urban storm water runoff, a significant and increasing fraction of pollutants in some waters of the U.S., originate from multiple activities. The industrial sector, one source category, is subject to federal and state-level storm water pollution prevention regulations, primarily General NPDES Permits that rely heavily on facility operators to identify themselves and develop appropriate site-specific pollutant controls. Degree of compliance is not readily determined and enforcement is inhibited because no publicly-available inventories contain data necessary to comprehensively identify facilities required to comply. This research evaluates the first stage of compliance, facility self-identification, concentrating on the motor-vehicle, transportation industry category using data at three scales: statewide, regional, and local or watershed. Data for California statewide and for the Los Angeles region show about 8 percent to 15 percent of motor-vehicle transportation facilities have complied with first-stage requirements. However, facility-specific evaluation in one Los Angeles County watershed suggests less than 50 percent of facilities in the industry conduct industrial activities of the kind covered by regulations; others need not comply. Results show strong variation by industry category. Second-stage compliance, follow-up reporting, is also evaluated for the Los Angeles region. About 17 percent to 34 percent of facilities completing first-stage requirements have also completed second-stage requirements.

COMPLIANCE WITH STORM WATER POLLUTION PREVENTION REGULATIONS BY THE METAL FINISHING INDUSTRY1

ABSTRACT: Federal and state storm water pollutant control regulations for industry require facilities to identify themselves and to implement appropriate controls specifically developed for each facility by its operators. Compliance is not directly observable from publicly reported information, and is believed to be low. Compliance requirements are divided into three stages: determination and notification of duty to comply; preparation of public reports and site-specific planning documents; and implementation of pollution prevention activities. Aggregate data show about 25 percent to 35 percent of metal plating facilities in California, and about 35 percent to 40 percent of facilities in the Los Angeles region, have recognized the need for first-stage compliance; the number required but failing to do so is not known. For second-stage compliance, between 77 percent and 88 percent of facilities submitted required annual reports from 1993 to 1995, while on-site water quality monitoring reports were submitted by about 60 percent of required facilities. Site investigations of ten Los Angeles area facilities showed variation in compliance with site-specific documentation and implementation requirements. Most facilities inadequately evaluated activities for potential storm water pollutants, and most prepared incomplete plans for storm water sampling and inspection procedures. Evaluation of third-stage compliance by evaluating quantitative effects of facility actions, beyond the scope of this research, is recommended.

Outlining policy responses to stimulate automotive car demand by environmental impact reduction

The aim of this paper is to propose an alternative approach for outlining policy responses to stimulate the automotive industry. The scientific community has developed and employed the Delphi method to collect and convey perspectives and impressions, and also define a number of financially viable proposals. The panel of experts takes the view that traditional industrial policy measures denote limited effects to stimulate car demand, in a context of a macro-economic downturn. By contrast, the panel also believe incentives for car demand are important for environmental purposes, for safety and for the diversification of energy sources. The policy measures proposed are fundamental from the viewpoint of overturning path dependencies in the automotive industry which impede the diffusion of alternative vehicles, with respect to business models and consumer attitudes.
