Detoxication of Water Media, Containing Thiazine Dye with Use of Microalgae

摘要

The process of purifying wastewater which contains methylene blue by using green microalgae Chlorella and Chlamidomonas sp. has been researched. It has been found out that in the process of cultivating both Chlorella and Chlamydomonas in such water, the concentration of dye is reduced and the purification process with Chlamydomonas is more efficient. It has been demonstrated that with increasing the concentration of methylene blue to 10 μM L?1, the obvious increase of degradation degree is observed at using these algae which indicates the microalgae?s ability to sorbate the dye. The degree of purification from the xenobiotic in the variants with Chlamydomonas amounts to 70% and with Chlorella amounts to 40%. Using microalgae for wastewater treatment wouldn?t require rearrangement or capital construction of new wastewater treatment facilities. Besides there is an opportunity of using microalgae after the wastewater purification as green manure for melioration agriculture, soils remediation or waste composting. The application of algae strains endued with principally new opportunities of wastewater treatment will allow amending the environmental situation and creating a secure system of environmental enhancement.
