Purpose of the work is to analyze existing wetland systems,
biotechnologies on using hydrobionts and aerated lagoons in wastewater treatment
systems. Task of the work is to elaborate experimental wastewater plant unites based
on its function characteristics for suggesting improved models. Relevancy of the work
is the increasing environmental pollution caused by wastewaters and urgent need for
improved implemented wastewater treatment systems. Study methods used in the work
included general scientific methods as system analysis, induction, deduction. Obtained
results of experimental studied concluded the following: the efficiency of different
pollutants removal is higher in hybrid constructed wetlands than in one-stage systems;
hybrid constructed wetlands not only resolve ecological problems about wastewater
management but can also provide landscape and educational profits because of their
interesting shapes and innovative methods used; long term research on the operation
of constructed wetland systems in Poland indicate that these systems can be used with
great success on rural areas, especially in protected areas and valuable landscapes in
Ukraine; cyanobacteria biomass, released from cultural medium, can be used for
production of small tonnage valuable products with unique properties, large tonnage
biomass of natural origin can be used for fuel production (biomethane, bioethanol,
biodiesel); suggested two-stage purification scheme of landfill infiltrates enables to
purify infiltrates effectively with primary purification under conditions of aerobic
lagoon on the territory of landfill, transporting of infiltrate with the help of pipeline
«landfill – municipal PCF», dissolving it with municipal sewerage effluents and
pretreatment on municipal PCF.
