污染物达标排放

大气污染物达标排放阈值模型的建立与应用

Modeling and application of emission threshold of atmospheric pollutant to achieve the standard

该模型先综合评价了系统大气环境质量等级，再根据不同评价结果计算单项大气污染物达标排放阈值。

After comprehensive evaluation of atmospheric environmental quality , the emission threshold of single atmospheric pollutant can be calculated .

基于改进型灰色聚类分析方法建立的大气污染物达标排放阈值计算模型，使得各项污染因子的实际排放量一一对应于某个非零权重值。

Each real emission value of pollutant factor is uniquely corresponding with a nonzero weight , while zero weight problems occur with the classical grey clustering analysis method .

污染物达标排放监控与污水排放计量监控成为污水自动化监控系统的两大重点难题。

The supervision and the measurement of the discharge of pollutants to satisfy the standard become two main problems in the automatic monitoring and control system of wastewater treatment .

水质综合评价结果表明，乡镇排污口的主要污染是生活污染，污染物均达标排放。

Comprehensive assessment on water quality shows that the discharge outlets are mainly polluted by living pollution , and that the discharge meets the national standard .

阐述了主要大气污染物“达标排放”（浓度控制）和“总量控制”之间的联系和区别；以及各自的法律地位；

This paper describes the relation and difference of " emission up to standards " and " total quantity control " ofmain atmospheric pollutants , as well as their legal status .

处理后的烟气指标为：沥青烟浓度13.8mg/m3，苯并（a）芘浓度0.053×10-3mg/m3，烟尘浓度19.1mg/m3，各项污染物均达标排放。

The observed index after processing indicated that concentration of asphalt gas emission was 13.8mg / m3 , benzene ( a ) pyrene 0.053 × 10-3mg / m3 and dust 19.1mg / m3 , which all satisfied the national standard .

评价工作的重点内容为平台各类环境保护设施的运行及污染物的达标排放情况、污染防治措施的效果及海洋石油开发生产对海洋环境的影响程度。

The emphases content of assessment must be the run situation of the environment protecting establishment , the situation about the pollution discharge , the effect of pollution prevention and cure , effect degree about the marine environment caused by marine petroleum exploitation .

传统的生产者环境责任主要集中在生产过程阶段，被追究的法律责任主要是以污染物的达标排放和排污收费为形式，其理念是污染物的末端治理。

The traditional producers ' environment legal liability mainly concentrates in the production process stage , the legal liability which is investigated mainly takes the pollutant standards emissions and the pollution charge as the form , its idea is the terminal pollutant governing .

结果表明：Cr6+对鱼外周血红细胞有致突变作用，并有明显剂量效应关系；试验期间废水特征污染物均达标排放，未对生物监测塘中的鲤鱼和鲫鱼产生明显的遗传损伤；

Results showed that the genotoxicity caused by Cr6 + was dose dependent , with wastewater up to the discharge criteria and no obvious genotoxic effect on Cyprinus carpio and Carassius auratus , and result of micronucleus test was comparable with that of the conventional acceptance monitoring .
