摘要:
针对不同泥质的供水污泥，开发了污泥浓缩脱水一体化工艺及其成套中试设备（浓缩深脱一体机），并优化了设计和运行参数。对于脱水性较好的供水污泥，仅需投加聚丙烯酰胺（PAM），该设备在进泥量较小的条件下即可使出泥含水率低于70%；对于脱水性较差的污泥，分别考察了联合投加PAM和污泥改性剂，以及联合投加PAM和石灰乳两种调理方案对污泥脱水效能的影响，并对不同调理方案进行了技术和经济指标分析。结果表明，在达到目标含水率前提下，当单独投加PAM、联合投加PAM和改性剂、联合投加PAM和石灰乳调理污泥时，设备处理量分别为130、200和330 kgDS/h，处理成本分别为171.24、262.44和150.60元/tDS。因此，联合投加PAM和石灰乳进行供水污泥调理可提高产能、降低处理成本，推荐在实际生产中使用。
Abstract:
An integrated sludge thickening and dewatering process and a complete set of pilot device (integrated sludge-thickening and deep-dewatering machine) were designed and developed to treat different kinds of waterworks sludge, and the design and operational parameters were optimized. For waterworks sludge with good dewaterability, the sludge water content could be reduced to lower than 70% after treated by the device fed with a small amount of sludge when only PAM was added. For waterworks sludge with bad dewaterability, effects of two sludge modifier addition modes (combined addition of PAM and sludge modifier and combined addition of PAM and lime milk) on dewatering efficiency were investigated, and technical and economic indices of different conditioning methods were analyzed. On premise of reaching the target water content, the operational capacities of the device after adding PAM alone, PAM and modifier and PAM and lime milk were 130 kgDS/h, 200 kgDS/h and 330 kgDS/h, and the treatment costs were 171.24 yuan/tDS, 262.44 yuan/tDS and 150.60 yuan/tDS, respectively. Therefore, the combined addition of PAM and lime milk for waterworks sludge conditioning can increase the productivity and reduce the treatment cost, so it is recommended to be applied in practical production.
