在实际工程中水解池由于活性污泥量问题,水解效果不好.针对传统工艺的不足,研究采用改进型编织设备,以PP棉为衬底、涤纶丝为骨架、生物碳纤维为核心制备特殊处理(ST)-仿生填料,将其加入水解池中以期提高水解效果,并开展了处理效果实验验证.实验结果显示:该填料具有优良的生物附着性,可极大提高微生物附着量,从而使废水的可生化性得到强化;在挂膜实验中,ST-仿生填料表面的活性污泥量在前20d快速增长,20d之后活性污泥量可基本稳定在1.4kg/m;与传统活性污泥法相比,ST-仿生填料生化反应系统对废水中COD的去除率可提高5%~14%左右.鉴于ST-仿生填料灵活的装配方式和良好的处理效果,其在工业污水处理厂水解酸化池、生化池等生化段提标改造工程具有较好的推广应用前景.
The hydrolysis efficiency was not good in actual hydrolysis engineering due to the problem of insufficient total activated sludge quantity.In order to overcome the shortcomings of these traditional pro-cesses,this study utilized an improved knitting equipment to prepare a special treatment(ST)-bionic fill-er with PP cotton as the substrate,polyester fiber as the skeleton,and biological carbon fiber as the core.This fiber was put into hydrolysis tank to enhance the hydrolysis efficiency,and experiments were con-ducted to verify its treatment effectiveness.The experimental results showed that the filler possessed ex-cellent biological adhesion and microbial attachment amount,thereby enhancing the biodegradability of wastewater.In the film culture experiment,the amount of activated sludge on the surface of ST-bionic fill-er showed rapid growth within the initial 20 days,and the amount of activated sludge could be basically stabilized at 1.4 kg/m after 20 days.Compared with the traditional activated sludge method,the removal proportion of COD in wastewater by the ST-bionic filler biochemical reaction system could be raised by about 5%to 14%.In view of the flexible assembly method and excellent treatment effect of ST-bionic fill-er,this filler held a promising potential for widespread application in upgrading projects of industrial wastewater treatment plants,particularly in hydrolysis acidification tanks and biochemical reactors.
