摘要
练市水厂通过使用型号为BI-CHEM 1008CB的新型菌种,生化系统的COD去除率提高15%左右,色度的去除率提高了10%~20%,减少了脱色药剂用量,降低了水厂运行成本。同时此菌种在一定程度上能改善污泥活性,试验进行一段时间后,污泥结构致密、沉降性较好,且此菌菌种对COD降解的稳定性较好。
Through use of the new bacteria BI-CHEM 1008CB, the biochemical system COD removal rate of Lianshi wastewater-treatment plant is improved about 15 %, chroma removal rate increases 10 %-20 %, reducing bleaching reagent dosage, reduce the operation cost. At the same time, the new bacteria in a certain extent can improve the activity of activated sludge. Test for a period of time, the compact structure and sedimentation of sludge is better, and this bacteria for COD degradation stability is good.
