将生命周期评价方法应用于天津市芥园自来水厂,以该水厂气浮/气水反冲滤池工艺流程为基础,进行了环境与经济影响的评价。结果表明,芥园自来水厂所采用的工艺成熟可靠,可满足稳定达标的供水要求;但不可避免的是,仍然有少量有毒有害气体、污泥以及噪声排出,很可能会对周围人居环境造成影响,所以尚需要更为合理的布局调整,以及对内部设施、绿化等进行提升改造。
The life cycle evaluation method was applied to the Japanese mustard garden waterworks. Based on the technological process of the flotation / gas-water backfiltration, the environmental and economic impacts were evaluated. The results show that the process used in the Seedling Waterworks is mature and reliable and can meet the water supply requirements of a stable standard. However, inevitably, there are still a few toxic and harmful gases, sludge and noise excreted, which are likely to cause environmental impact on the surrounding living quarters Therefore, we still need to make more rational layout adjustments as well as upgrade and upgrade the internal facilities and afforestation.
