The analysis of the general physical and chemical indicators and the maintenance of heavy metals of sewage of a bioenergy complex is carried out. It is established that the sedimentation rate of suspended particles in wastewater depends on the location of filtration fields with wastewater from the source of contamination. At the source, there is a maximum excess of the number of suspended particles with a minimum deposition rate. In all wastewater samples, the indicators of chemical and biological oxygen consumption exceeded the permissible standards by three orders of magnitude for reservoirs for recreational water use and those located within the settlements. Thus, this water cannot be discharged into any natural water basin and requires additional purification from organic matter. Also for this water, the use of biological treatment methods without additional chemicals is ineffective. The presence of a complex of macro- and microelements in wastewater in combination with a high content of organic matter (humus and sulfonic acids) may be the basis for their use as raw material for fertilizer production.
