【正文】 order to get the pure products of flocculants, the paper used acetone to purified the bioflocculant preliminary, the yield of flocculant is min1 for 42 h, the flocculating activities achieved over 96%.In order to investigation the application area of the bioflocculant, bioFlocculants precipitation was used to treat the simulated wastewater, such as methylene blue solution, Kaolin solution, Humic acid, Sludge wastewater, whose concentration is 1gL1potassium nitrate, the inorganic salt is the position of 2 gL1cane sugar and 10 gL1。為了考察微生物絮凝劑的應(yīng)用范圍,本文采用微生物絮凝沉淀法對1gL1磷酸二氫鉀、5 gL1蔗糖, g到目前為止,國內(nèi)外對滲濾液的處理有很多種方法,但對于生物絮凝沉淀生物聯(lián)合強(qiáng)化技術(shù)的研究較少,利用傳統(tǒng)的生物處理法對濾液中的COD和色度的降解率低,而利用生物絮凝沉淀生物聯(lián)合強(qiáng)化技術(shù)可以有效解決這一難題,以便最大程度地降解水中的污染物,而且微生物絮凝劑本身無毒無害,對人類的健康和環(huán)境保護(hù)有很重要的現(xiàn)實(shí)意義。本文從土壤中分離并篩選出一株具有較高絮凝活性的微生物絮凝劑產(chǎn)生菌,命名為Be3,通過菌體的形態(tài)特征、革蘭氏染色以及生化試驗(yàn)結(jié)果,初步鑒定Be3為葡萄球菌屬。L1脲, g gL1的次甲基藍(lán)模擬廢水、高嶺土模擬廢水,腐植酸模擬廢水和污泥廢水進(jìn)行處理,實(shí)驗(yàn)結(jié)果表明該微生物絮凝劑對模擬污水的有很好的處理效果,尤其對濁度的去除率比較高,處理高嶺土溶液時(shí),%。為了獲得純絮凝劑產(chǎn)品,本文采用丙酮法對微生物絮凝劑進(jìn)行了初步純化,其產(chǎn)率較高,L1lactose, the nitrogen source is the position of gL1potassium dihydrogen phosphate, 5 gL1,the result of erperiment show that bioflocculant have a good treatment effect on the turbidity of simulated wastewater, the removal rate of turbidity achieve % to the kaolin united technologies of microwave fenton process and biofluccents precip
