Development of technology for biological treatment of wastewater contaminated with oil and oil products using aquatic plants and algae

Abstract

In the context of advancing "green" development and global environmental standards, there is a pressing need to focus on biological methods of wastewater treatment in Kazakhstan, particularly concerning oil pollution. This study aims to develop an optimal technological model to minimise destructive pollution of wastewater by oil products using algae and aquatic plants on the example of artificial bioponds within the Ozen field owned by "Ozenmunaigas" JSC in the Mangistau region. Through a comprehensive set of scientific methods including induction and deduction, abstraction, system analysis, synthesis, concretisation, formalisation, and generalisation, the study assesses the ecological state of water resources, identifies pollution dynamics, and evaluates the impact of algae and aquatic plants on oil-contaminated effluents. The research culminates in the development of an effective biotreatment technology to mitigate the negative effects of wastewater on water quality and enhance Kazakhstan's overall environmental landscape. Furthermore, the study explores innovative technological and management approaches to reduce pollutant concentrations, emphasizing the importance of ecosystem-based solutions and modern bio-treatment technologies. The findings hold practical significance for modernizing water treatment system, informing future preventive measures for water resource protection, and promoting the adoption of biological treatment as a viable alternative to traditional methods.
