卧螺离心机污泥脱水絮凝剂的选择

Selection of dehydration flocculant for slurry centrifuge

针对污水处理厂絮凝剂招标,通过实验室大量小试按照一定的评分标准综合评价,筛选出一部分溶解性能好,絮凝效果甚佳的药剂进行上机实验,并在小试中确定离心机最佳配药浓度为2.0‰。从出泥量、出泥含水率、滤液中的悬浮物等多个方面进行比较,为最终的药剂比价招标提供数据参考。

Aiming at the bidding of flocculant in sewage treatment plant,a large number of small experiments in the laboratory were evaluated according to certain scoring criteria,and some of the agents with good dissolving performance and good flocculation effect were screened and the centrifuge was determined in the small test.The optimum concentration of dispensing was 2.0 ‰.From the mud volume,mud moisture content,suspended solids in the filtrate and other aspects of comparison,for the final drug bidding to provide data reference.
