摘要
在预沉池中采用放养鲢鱼的生物操纵技术可高效、稳定地控制藻类数量,并对原水浊度、氨氮起到稳定作用,在高藻期还可降低原水CODMn、总磷浓度等。采用生物除藻技术,再联合常规处理工艺除藻,可以使藻类得到较彻底的去除。特别是对于以蓝藻为优势种的夏季原水,该联合技术的效果更为明显。
Biological control technology, breeding sliver carp in pre-sedimentation tank, can con- trol the quantity of algae effectively, keep the turbidity and ammonia nitrogen of source water steady, and reduce oxygen consumption and phosphorus concentration of source water at high algae period. The com- bination of biological control technology and conventional water treatment process can remove the algae in source water completely. Especially for source water in summer, whose dominant species is blue-green al- gae, the combination technology has more obvious control effect.
