季节变化对渗沥液原水性质及处理效果的影响
|
摘要
分别选取2017年7月和2016年12月作为上海夏季、冬季的参照样本,研究了夏冬两季变化对上海某焚烧发电厂渗沥液处理站原水性质及处理效果的影响。对这两个月内渗沥液处理站每日的原水及各阶段出水进行取样,分析了pH、SS、COD、NH3-N等指标。结果表明:无论是冬季还是夏季,渗沥液原水都呈弱酸性,夏冬两季pH差异不大;夏季渗沥液原水的水量、SS、COD、NH3-N普遍高于冬季渗沥液,与气温及降雨量密切相关;此套渗沥液处理工艺运行稳定,处理效果良好。
In this experiment,July 2017 and December 2016 were selected as samples for summer and winter in Shanghai. The effect of seasonal variation on raw leachate quality and removal efficiency for solid waste leachate treatment was studied. Daily raw leachate and effluent water at each stage of leachate treatment station were detected as samples,and pH,SS,COD,NH3-N and other indicators were analyzed. The results showed as follows. In both winter and summer,raw leachate had weak acidity,and pH difference in summer and winter was not significant. Water volume,SS,COD and NH3-N of raw leachate water in summer were generally higher than that in winter,and were closely related to temperature and rainfall. This set of leachate treatment process was stable and effective.
