Embodiment

[0025] The malachite green dye wastewater was taken from the wastewater outlet of the printing and dyeing process of the printing and dyeing factory, and the measured malachite green concentration was 32mg / L. Acclimate Saccharomyces cerevisiae and prepare Saccharomyces cerevisiae materials loaded with loofah sacs. The prepared materials are used to treat malachite green dye wastewater. The experimental group without adding materials is used as the control group to determine the degradation effect of malachite green in the experimental group and the control group. After the experiment, small pieces of loofah sacs were recovered and reused to treat malachite green dye wastewater. Specific steps are as follows:

[0026] (1) Cultivation of Saccharomyces cerevisiae spores: prepare solid medium to cultivate Saccharomyces cerevisiae spores, the medium formula is yeast powder 100mg / L, peptone 200mg / L, agar 180mg / L, malachite green 5mg / L~20mg / L (step by step increase), pH=7.0, the cul...

Abstract

The invention discloses a method for degrading malachite green waste water by using loofah sacs to load Saccharomyces cerevisiae materials. The method comprises the following steps: (1) cultivation of Saccharomyces cerevisiae spores; (2) selection and treatment of loofah sacs; (3) preparation and cultivation of loofah sac-loaded Saccharomyces cerevisiae materials; Treatment of Malachite Green Dye Wastewater; (5) Recycling and reuse of Saccharomyces cerevisiae loaded material in loofah sac. The loofah sac loaded with Saccharomyces cerevisiae prepared by the invention is green and economical, can realize efficient degradation of malachite green, and has the advantages of easy solid-liquid separation and efficient recycling, and has great application in the actual treatment of malachite green wastewater potential.

Description

technical field [0001] The invention belongs to the technical field of wastewater biological treatment in the field of environmental protection and the technical field of microorganism immobilization, and in particular relates to a method for degrading malachite green wastewater by using loofah sacs to load Saccharomyces cerevisiae materials. Background technique [0002] With the rapid development of the economy, industries such as textiles, printing and dyeing, leather, and papermaking have risen rapidly. While these industries have brought about economic growth, they have also brought serious pollution to the natural environment we depend on for survival. Malachite green is a synthetic organic dye that is widely used in textile, printing and dyeing industries. A large amount of residual malachite green pollutants enter the environment with factory wastewater, polluting water bodies and land. To make matters worse, the malachite green molecule contains chlorine and the rin...
