为进一步科学设置城市环境空气质量自动监测站点位,确保全面、真实、客观地反映区域环境空气质量状况及污染物的传输、迁移、转化情况,文章通过对环境空气质量自动监测点位的地理位置、周边环境、周边污染源及15天的比对监测结果进行分析的基础上,得出在调整点位与原点位各污染因子变化趋势基本一致的情况下,对点位进行优化调整可以避开周边污染源影响,使得调整后的点位更能真实、准确、客观地反映该市的环境空气质量.

The paper expounds the construction of artifi cial wetlands to reprocess the tail water of township sewage treatment plants,and concludes that the artifi cial wetlands can further improve the removal rate of major pollutants such as chemical oxygen demand,ammonia nitrogen and total phosphorus in the tail water, further improve the surrounding water ecological environment while meeting the requirements of upgrading and reconstruction of township sewage treatment plants, and further improve the economic and social benefi ts of sewage treatment plants by building a reclaimed water recycling system.
