摘要
臭氧活性炭处理工艺在国内外逐步得到推广和应用,但应用中发现部分无脊椎动物及其幼虫能够穿透砂滤池进入炭池并大量繁殖。分析了炭滤池中无脊椎动物出现并孳生的原因,对国内外炭滤池中出现的主要无脊椎动物种群及其变化规律进行了归纳,提出了国内外炭池无脊椎动物研究结果存在差异的原因。通过对炭滤池反冲洗控制、水处理单元的优化和预氧化等对无脊椎动物去除效果的总结,分析和比较了现行的控制技术及其可行性。
At home and abroad, ozone/activated carbon process has be promoted and applied gradually. However, some invertebrates and their larvae can penetrate through the sand filters into the carbon filters and be substantially reproduced. Reasons for existence and propagation of invertebrates in carbon filters are analyzed. The species of invertebrates existing in domestic and overseas carbon filters and their variation rules are detailed, and the reasons for difference between the domestic and overseas research results are proposed. The existing control technologies and their feasibility are analyzed and compared through summing the removal efficiency of invertebrates by baekwashing, optimizing water treatment and preoxidation.
