生物膜法水处理用悬浮填料的筛选

为了筛选一种水处理性能良好,经济成本低的悬浮填料,对四种悬浮填料进行生物挂膜、抗冲击负荷、悬浮填料本身性质以及经济成本等进行综合对比研究。试验结果表明,经化学氧化-铁离子覆盖技术改性的悬浮填料不但水处理性能良好,而且经济成本较低,是生物膜法水处理中的首选填料。

Screening of suspended filler for biomembrane process in wastewater treatment

In order to choose a kind of suspended filler whose water treatment performance is good and economic cost is low, four kinds of suspended filler were compared and studied in aspects of biomembrane forming, anti-shock loading, physical nature, economic cost and so on. The results of the test showed that, the suspended filler, modified by the technology of chemical oxidation-surface covered with iron ion, not only had good water treatment property, but also with low economic cost, which should be the first choice for the biomembrane process in water treatment.
