WATER TREATMENT APPARATUS

FIELD: process engineering.SUBSTANCE: invention relates to water treatment and can be used for water ozone treatment. Proposed device comprises water feed pipeline with strainer, water discharge pipeline, pipeline to feed ozone from ozone generator connected with ejector, means to discharge ozone-bearing gas, discharge pipeline, bypass pipeline with check valve, hydraulic lock, pump, filtration vessel with bed filter, drainage system level indicator, 1, 2, 3and 4shutoff devices, control unit connected with gages and control circuits of ozone generator, pump hydraulic lock and 1, 2, 3and 4shutoff devices. Note here that ozone feed pipeline is connected with ejector. Means to discharge ozone-bearing gas is composed of ozone destructor arranged atop filtration vessel and connected therewith via air shutoff valve. Flushing water discharge pipeline is connected with discharge from filtration vessel via hydraulic lock. 3shutoff valve is arranged in water feed line downstream of strainer to connect it with ejector and bypass line with check valve connected via 2shutoff valve and pump with drainage system outlet and, via 4shutoff valve with water discharge line. 1shutoff valve arranged in branch pipe of water feed line downstream of said strainer connects the latter with drainage system. Bed filter is composed of catalyst consisting of pelletised nano-structured based of natural green earth, thermally expanded graphite without extra binder. Sprayers are arranged at filtration vessel top part and connected with shutoff valve and pump and are automatically controlled along with ozone generator by control unit. Note here that sprayer nozzles are located: One at the center while others are arranged in concentric circles located in one plane, their number being defined by calculation.EFFECT: higher quality of cleaning and efficient use of ozone.2 dwg Изобретение относится к технике водоподготовки и может быть использовано для озонирования питьевой воды систем централизованного водоснабжения.
