以低污染水质期的黄河水作为对比,研究了两种不同类型污染水质期源水(滦河水和黄河水)中的有机物和藻类对滤池堵塞的影响,以及臭氧预氧化的控制效果。研究显示,藻类对滤池堵塞有重要影响,滦河水以个体较大的蓝藻为主,黄河水以个体较小的绿藻为主,其中处理滦河水的滤池堵塞较为严重。两种微污染源水中,颗粒态有机物、溶解性有机物所占的比例不同。其中,黄河水的溶解性有机物含量高,造成气浮出水的大粒径颗粒比例增加,容易缩短滤池的运行周期;同时臭氧预氧化强化去除颗粒物的效果不明显,但能延长滤池的运行周期。滦河水中的“颗粒态”有机物所占比例较大,臭氧预氧化强化去除颗粒物的效果明显,但水头损失增长曲线表明,经臭氧预氧化后其过滤呈现出表层过滤的特性。
The effects of organic matter and algae in two different types of contaminated water sources on the clogging of the filter and on the control effect of ozone preoxidation were compared with the Yellow River water in the low pollution water quality period. Studies have shown that algae filter blockage has an important impact, Luanhe water to individual larger cyanobacteria, the Yellow River water to individual smaller green algae, of which the Luan River water treatment filter blocker more serious. Two micro-polluted sources of water, particulate organic matter, dissolved organic matter in different proportions. Among them, the Yellow River water has a high content of dissolved organic matter, which leads to an increase in the proportion of large particles with flotation effluent, which can shorten the operation period of the filter. Meanwhile, the effect of ozone preoxidation to remove particulate matter is not obvious, Operation cycle. Luan River water “particulate state ” organic matter in a larger proportion, ozone pre-oxidation to strengthen the removal of particulate matter obvious effect, but the head loss growth curve shows that after ozone pre-oxidation filtering showed a surface filtration characteristics.
