Abstract

The invention discloses a method for processing paper-making waste water in the way of structuring artificial flora, including selecting more than two strains of Halomonas sp. flora and Bacillus sp. flora respectively for sterile culture to lead OD620nm to reach over 10.0 and then mixing the bacterial liquid by volume rate to structure the artificial flora; inoculating the paper-making waste water of pH being 9-11 and COD being 1,000-140,000mg l <-1> with the structured artificial flora, conducting stationary treatment for a certain time at 35-38 DEG C with intermittent stirring, in the treatment process, sampling at intervals to measure the pH, chroma and COD index of the paper-making waste water and finishing the treatment when the pH reduces to 7.0-8.8. The method is characterized by simple structure of the flora to be structured, obvious effect in direct treatment, strong controllability and repeatability and the like, and has great application prospect in the treatment aspects of waster water such as the control over the paper-making waste water.

Description

technical field [0001] The invention relates to a method for treating waste water by means of flora, in particular to a method for treating papermaking waste water by constructing artificial flora and obtaining a process route of a two-step treatment mechanism. Background technique [0002] At present, the demand for paper in the world is showing a sharp upward trend. In developed countries, because the pulp raw materials are mainly wood, a large number of forests and wood are gradually decreasing. The lack of wood raw material resources makes straw pulp papermaking very common in developing countries. Straw pulp papermaking derived from the alkaline pulping process has the advantages of good paper quality and cheap and abundant raw materials. But as we all know, the biggest disadvantage of straw pulp papermaking is the serious pollution to the environment due to the high pollution load. [0003] Different from wood pulp wastewater, straw pulp papermaking wastewater has the...
