专业:市政工程

摘要
地下水具有水质优良、水量稳定、分布范围较广等优点,是城市和乡镇供水
的重要组成部分。近年来,由于人类对于环境的不重视,造成地下水中的铁、锰、
氨氮超标及其它污染问题,已成为影响城市供水水质安全的重要因素。本文就西
安市西北郊地下水水源地 11 号管井水质进行了长期的监测分析,得出地下水水质
中铁、锰、氨氮严重超标,浊度和色度污染指标时有超标的现状。选定以去除铁、
锰和氨氮等为主要控制指标,进行现场中试实验,为地下水水厂的工艺改造提供
依据。
在本文试验中,石英砂滤料完全成熟时,已在其表面覆盖有一层“黑膜”。
采用“一级砂滤+二级活性炭”的处理工艺,经过曝气方式比对选定“前置喷淋+
后置跌水”的充氧方式,进行中试试验研究。
系统通过在不同进水浓度和不同滤速下分别对于各种污染物控制指标的处理
效果表明,Fe、Mn、氨氮、浊度的平均去除率均在 90%以上,对于CODMn和UV254
的平均去除率分别在 20%和 30%左右,处理效果稳定,且不随浓度和滤速的变化
而有大的波动,具有较强的适应性。
通过对砂滤滤层沿程分析表明,在滤柱滤层 0-70cm 对 Fe、Mn、氨氮、色度
和浊度已大部分去除,并由此确定滤层的最佳厚度为 110cm。
通过对砂滤反冲洗废水的处理研究,进行静态烧杯试验,不同混凝剂的混凝效
果研究表明,选定 PAC 为混凝剂,投加量为 70mg/L,选择 PAM 为助凝剂,投加
量为。

Abstract
Groundwater, showing advantages in good quality, stable quantity and distribution
widely, is an ponent of water source in urban water supply industry. In
recent years, human ignore their responsibility for the protection of environment,
resulting in the pollution of groundwater by iron, manganese, ammonia and other
contamination, which has e an serious threaten to the safety of urban water
supply. This paper was based on the 11th tube-well of Northwest Groundwater Source in
Xi'an. The water quality of 11th tube-well was monitored for long-term, and the result
showed that the concentration of iron, manganese and ammonia nitrogen was seriously
overweight in this tube-well, with occasionally over standard in turbidity and color. The
study took iron, manganese and ammonia as the main subject, and carried out on-site
pilot test research in order to providing parameters for the technological transformation
of the groundwater plant.
In this experiment, the filter material, the quartz sand, was ful
