DISCRETE-PULSED ENERGY INPUT IN WASTEWATER TREATMENT TECHNOLOGIES

Wastewater treatment is an important environmental problem of the national economy any country. Therefore, increasing efficiency wastewater through use innovative technologies and equipment becoming relevant. Basically, for biological from organic biogenic pollution, aerotanks with different aeration systems are used. The mass transfer mixture waste water activated sludge accounts up to 80 % operating costs. article deals problems using thermal physics in by intensifying process accelerating oxidation reaction. intensification occurs due impact on treated medium (waste water) input energy discrete-pulse method. method implemented new heat equipment, namely a rotary-type aerator-oxidizer (AORT). A diagram technological scheme this apparatus presented. procedure has been developed determining volumetric coefficient oxygen gas phase liquid during treatment. number studies have carried out dependence concentration dissolved cycles at: angular speed rotation rotor unit; frequencies flow pulsations; shear rates. It shown that maximum reached 1–2 passes processed mixture. thermophysical characteristics operation aeration-oxidation plant determined depending frequency pulsations. comparative assessment heat-mass exchange indicators modern devices used AORT installation it when installation, costs reduced 20 %.
