摘要
分别研究了絮凝剂产生菌HHE-P7,HHE-P8,HHE-P21,HHE-P24,HHE-A26所产絮凝剂对高浊度建材废水的絮凝效果,并对影响絮凝作用的主要因素进行了探讨.絮凝效果表明,在碱性条件下,每1 L建材废水(2227NTU)中,投加8～10 mL含菌培养液浊度去除率均在92%以上,与常规絮凝相比,具有用量少,絮凝速度快的优点.
The flocculating effects of the flocculants produced by the flocculant-creating bacteria HHE-P7, HHE-P8, HHE-P21, HHE-P24 and HHE-A26 on the high-turbidity wastewater from building material production are studied respectively, and the main factors affecting the flocculation are discussed. The results of the flocculation showed that the removal rates of the turbidity of the wastewater, whose turbidity was 2 227 NTU, from the production of building materials by the bacteria-containing inoculums were all above 92%.
