The environmental problem has risen to a very high level today. An ecological catastrophe threatens the modern world not only because of unauthorized garbage dumps, but also because of the poisoning of reservoirs with sewage. Today, there are a variety of wastewater disposal systems. They are divided into global cleaning systems and stand-alone disposal systems.
Global sewerage system and wastewater treatment are city sewers that trap large particles of sewage waste and successfully solve the problem of recycling and disinfection domestic wastewater in million-plus cities. There are also systems for the disposal of industrial wastewater, they are built on the basis of industrial enterprises and purify wastewater from industrial waste. Not the last place in the environmental sphere is played by the sewerage system of atmospheric wastewater. Since the rainwater is not heavily polluted, special rainwater outlets are equipped for them, which transport wastewater to the main collector near the reservoir. After purification in accordance with sanitary standards, atmospheric waters are discharged into the reservoir.
Autonomous sewage systems are no less relevant today. They are used mainly in private households, kindergartens, schools that are not connected to the central sewerage system. Sewerage systems are being improved and modernized every day. The latest innovative discovery is biological wastewater treatment with autonomous systems VOC-1 and VOC-2.
Utilization of domestic wastewater occurs with the help of active vital activity of aerobic microorganisms, during which biochemical decomposition of organic pollution and waste occurs. Also, the system has a high capacity for deep filtration and utilization. In general, the phased wastewater treatment ensures the complete preservation of the ecosystem.
