摘要十二五时期是我国实现2020年环境小康建设目标的关键期。本文通过结合近五年天水市主要污染物排放情况，分析了天水市十二五期间废水废气主要污染物化学需氧量，氨氮，氮氧化物，二氧化硫的排放趋势，得出化学需氧量，氨氮，氮氧化物排放总量下降，二氧化硫排放总量上升的结论。进一步明确了各污染来源的排放情况，得出工业源，农业源由于产业调整所以排放量减少,而城镇生活源，机动车源由于排放量增加，是污染治理的关键。针对分析出的结果制定有效的减排措施并提出建议，为天水市十三五环境保护工作做参考。71864

Tianshui wastewater emissions of major pollutants emissions during the second five Analysis

Abstract Five-second period was our 2020 goal of building a moderately prosperous environment for the critical period。 By combining the past five years, emissions of major pollutants in Tianshui City, Tianshui City, analyzes the major pollutants COD, ammonia, nitrogen oxides, sulfur dioxide waste gas emission trends during the second five, drawn COD, ammonia, total nitrogen oxide emissions reduced sulfur dioxide emissions rose conclusions。 Further defined the emissions for each source of contamination, derived from industrial sources, agricultural sources due to the industrial restructuring and therefore reduce emissions, while urban life source, the source due to increased motor vehicle emissions, pollution control is the key。 Developed for the analysis of the results of effective measures to reduce emissions and to make recommendations, a reference to Tianshui Thirteen Five environmental protection。
