DEVELOPMENT OF BIOLOGICAL WASTE WATER TREATMENT

摘要

The proposed solution relates to devices for biological treatment of domestic wastewater with activated sludge and biofilm to produce highly efficient and environmentally friendly organomineral fertilizers. The biological wastewater treatment device contains autonomous column-type aerobic-anaerobic reactors made with the possibility of creating an upward-downward flow of water-water sludge mixture, with the placement in the central part on the downstream branch of the biofilm carriers, and subsequently nogo overflow water-sludge mixture from the reactor into the reactor, transport system comprising equipment for moving liquids and gases with the necessary piping. The pipelines are equipped with turbojets designed to create cavitation of low and high intensity, and oxidojets designed to enrich the water-sludge mixture with air, the biofilm carriers are made of synthetic materials with a specific density of 900-1300 kg / m in the form of hollow cylinders with external fins and with internal partitions to create a branched surface and channels to ensure the passage of water-sludge mixture, while to keep the media from the descent in the reactor installed Thus, the technology implemented in the proposed device is characterized by a high degree of biological treatment of domestic wastewater with activated sludge and biofilm to produce highly effective and environmentally friendly organomineral fertilizers.
