微生物菌剂在造纸废水中的试验研究

Experimental Study of Microbiological Agents in Papermaking Wastewater

以造纸废水为研究对象,开展微生物菌剂静态试验研究,评价LS-H、LS-G、LS-N三种型号微生物菌剂对造纸废水的处理效果。结果表明,在较短的时间内,三种型号微生物菌剂对造纸废水COD、TP等污染指标去除率分别达到40%和70%以上;在不影响活性污泥性能条件下,该微生物菌剂有助于强化废水生化过程,提高目标污染物的去除效率和出水水质;该微生物菌剂既适用于新建污水处理站的活性污泥激活和废水处理系统的快速启动,又可用于老旧污水处理站的改造,加快废水处理系统的恢复。

Taking the papermaking wastewater as the treatment object, the static test of microbial inoculants was carried out to evaluate the effect of three kinds of microbial agents of LS-H, LS-G and LS-N on the treatment of papermaking wastewater. The results showed that in a short period of time, the removal rates of COD and TP of papermaking wastewater by the three types of microbial agents reached 40 % and 70 % respectively. The microbial agent helps to strengthen the biochemical process of the wastewater and improve the removal efficiency of the target pollutant and the effluent water quality without affecting the performance of the activated sludge. It can be used not only for activated sludge activation of the new sewage treatment station and the rapid start-up of wastewater treatment system, but also in the transformation of old sewage treatment stations, and the recovery of wastewater treatment system can be accelerated.
