摘要：微生物絮凝剂（MBF7）处理废水效果显著。其生长条件对絮凝效果影响十分重要。实验表明，葡萄糖培养基较察氏培养基利于MBF7号菌生长；MBF7号菌的最佳培养条件为30℃，PH为7.5～8.5，摇床转速为150～200r/min,最佳菌龄为3～4天。为了确定微生物絮凝剂（MBF7）的应用范围和了解其处理废水的特性，本实验以微生物絮凝剂（MBF7）处理餐厅、印染和味精废水。结果表明， MBF7处理餐厅废水、印染废水和淀粉废水的浊度（或色度）的去除率分别达94%，90%和96%。MBF7处理效果优于AL2(SO4)3，安全高效，有很好的实际应用价值。

Abstract: The effection treated on sewage by bioflocculation（MBF7） is prominent.Its growing condition affects on flocculation very importantly. The experiment indicated the that:the PDA medium is more advantage to the Czapek Agar for the MBF7.The best grown condition of the MBF7 is that,the temperature is 30 ℃, PH is 7.5-8.5, the turning rate of the bed shaking is 150～200 r/ min.The best germ age is 3～4 days. For making sure the application of the bioflocculation(MBF7) and understanding the characteristic that it handles the waste water, this experiment is treating restaurant waste water, print and dye waste water and monosodium glutamate waste water with the bioflocculation(MBF7).The result indicates that the MBF7 handled the waste water of the restaurant, the print and dye waste water and the monosodium glutamate waste water to remove turbidity or color with the rate to 94% ,90% and 96% .The effect treated by MBF7 is more advantage than by AL2( SO4)3.And the MBF7 is safe and high-efficient.So it has good and actual application value.
