TECHNICAL RESERVOIR OF THE COMPLEX OF WASTEWATER TREATMENT AND METHOD OF ITS TRANSPORTATION, AND THE COMPLEX AND METHOD OF TREATMENT OF WASTEWATER WATER TYPE Russian patent published in 2017 - IPC C02F1/00 C02F9/00 C02F9/08 C02F9/14 

FIELD: chemistry.

SUBSTANCE: technical reservoir of the sewage treatment plant consists of a housing and a cover. The bottom of the shell is conical in shape and provides a system for automatic sludge dumping due to hydrostatic pressure. The cover has a tap for organized emission of harmful substances. The complex of wastewater treatment of the block-hardware type consists of a pressure collector and a receiving chamber; mechanical grating, sand trap and primary settler; anaerobic zone of bioreactor and aerobic zone of bioreactor; secondary settling tank; a metering pump for introducing the coagulant at the outlet from the anaerobic zone of the bioreactor before the secondary settler; Intermediate capacity; block of mechanical and sorption aftertreatment, consisting of a fast mechanical filter and an early sorption filter; pump, aeration compressor, portable plastic basket and/or tipping trailer, connecting pipeline and sump for sludge and sediment; disinfection plants; devices for sludge of dewatering and sediment disinfection. Mechanical grating, sand trap and primary settler are designed for mechanical cleaning and are modularly executed on the ground with the claimed technical tanks. Anaerobic zone of the bioreactor and aerobic zone of the bioreactor are designed for biological treatment and are executed modularly with the claimed technical reservoirs. Primary sedimentation tank, anaerobic zone of bioreactor, aerobic zone of bioreactor, secondary sedimentation tank, mechanical and sorption post-treatment block form a single technological line. The method of wastewater treatment by a complex of wastewater treatment of the block-apparatus type is characterized by the fact that the effluents from the pressure collector enter the receiving chamber of treatment facilities; further drains enter the mechanical grilles; from the mechanical grids, the drains are fed to the sand trap. Removal of sediment from the sand trap is carried out in a bag filter; further, the effluents enter the primary settler. Removal of sediment from the primary settler is carried out through a pipeline to the pit; Further, the flows go by gravity to the anaerobic zone of the bioreactor, in which the degradation of difficultly oxidized organic matter takes place on the biocarrier with immobilized and free-floating microorganisms; further, the effluents enter the aerobic zone of the bioreactor, in which nitrification takes place under the action of aerobic nitrifying bacteria and aeration; further, the treated effluents are transported by gravity into the secondary settler. Before the secondary settler, at the outlet from the anaerobic zone of the bioreactor, a coagulant is injected by means of dosing pumps. The removal of sludge settled in the secondary sedimentation tank is carried out via a pipeline to the pit; further purified effluents enter the intermediate tank, from where they are fed by pumps to the mechanical and sorption post-treatment unit; further purified effluents are sent to the disinfection unit; sediment and sludge from the pit are pumped to the sludge dewatering device and a sediment disinfection unit.

EFFECT: increasing the sanitary reliability, ecological safety and economy of installation, expansion of the field of application.
