Abstract

The invention discloses a compound microorganism live bacteria preparation for enhancing activated sludge, a preparation method and applications thereof. The preparation contains Bacillus fusiformis, Comamonas sp. and Ochrobactrum sp.. The preparation method comprises the following steps: first, Bacillus fusiformis, Comamonas sp. and Ochrobactrum sp. after inclined plane activation are inoculated in liquid mediums respectively, and cultured at the temperature of 30 DEG C-37 DEG C for 40-54 h to obtain a microorganism bacteria liquid; second, the microorganism bacteria liquids obtained from the first step are mixed uniformly, dried at the temperature of 40 DEG C-60 DEG C, and the processes of crushing to 15-50 meshes and sieving are performed. The preparation can enhance activated sludge performances effectively and rapidly in applications as an activated sludge COD-degrading enhancer in the papermaking wastewater treatment process. The preparation can degrade papermaking wastewater COD efficiently and improve wastewater chromaticity and water quality.

Description

technical field [0001] The invention belongs to the field of microbial environmental protection, and in particular relates to a composite microbial live bacteria preparation for strengthening activated sludge and its preparation method and application. Background technique [0002] Papermaking wastewater can be roughly divided into: pulping cooking liquor, washing wastewater, bleaching wastewater and paper machine white water. Alkali pulp cooking waste liquor, also known as "black liquor", is the main source of pollution in pulp mills. The composition of pulping and papermaking wastewater is complex, and its composition not only depends on the method of pulping, but also depends on many factors such as the type of product and the type of raw material. Suspended substances in wastewater mainly come from fibers and fillers lost in various processes of pulping and papermaking; BOD mainly comes from pulping and cooking processes, such as sugars, alcohols, organic acids, etc. ge...
