Old wastewater treatment facilities of the Leylek District Territorial Hospital
After the installation of the new wastewater treatment system, the old treatment facilities were not dismantled, and no land reclamation work was carried out on their territory. This ultimately led to the marshy condition of the area and the infiltration of the accumulated mass into the groundwater.
According to specialists, poorly treated wastewater and sewage from the city hospital deliver organic matter to the rural canal. The water is then used for irrigating arable land in the district's agricultural sector, consumed by livestock, and used by people. However, due to the long absence of repairs and the emergency state of the facilities, the waste is not fully filtered.
Wastewater is discharged into drainage systems, ditches, watercourses, and rivers, creating unsanitary conditions, especially in receiving water bodies with low water exchange.
Experts assert that the entry of wastewater into water bodies can also provoke the spread of diseases such as diarrhea, cholera, and various types of hepatitis. This type of pollutant poses a significant danger to all living beings, as it contributes to the development of cancer diseases.
Alongside this, untreated wastewater reduces the dissolved oxygen content in open water bodies, leading to the degradation of aquatic systems. The depletion of dissolved oxygen in the water decreases the productivity of reducers in the process of decomposing the biogens that come with the wastewater, but it does not affect the activity of anaerobic bacteria - reducers that multiply and spread a foul odor (the smell of sewage). The enrichment of water bodies with biogens stimulates the growth of phytoplankton, causing the water to become murky, plants to die, and the concentration of oxygen to decrease, i.e., eutrophication of water bodies occurs.
Water pollution by wastewater leads to a decrease in its productivity as a habitat, making it impossible for human use; it becomes unsuitable for domestic, agricultural, and industrial processes.
