dc.description.abstractДосліджено закономірності кавітаційного очищення стічних вод харчових та хімічних виробництв від органічних та біологічних забруднень у присутності газів різної природи. Встановлено оптимальний діапазон температур 313–318 К для кавітаційної обробки стічних вод. Показано, що процес кавітаційного руйнування органічних сполук можна описати кінетичним рівнянням першого порядку. Підтверджено ефективність барботування газів у кавітаційну зону з метою інтенсифікації одночасного руйнування мікробіологічних та органічних забруднень у стічних водах промислових виробництв.
dc.description.abstractThe regularities of cavitation treatment of food and chemical industries wastewater from organic and biological contaminants in the presence of gases of different nature were studied. The optimal temperature range 313–318 K for cavitation wastewater treatment was established. It is shown that the process of cavitation destruction of organic compounds can be described by a first – order kinetic equation. The efficiency of gas bubbling in the cavitation zone in order to intensify the simultaneous destruction of microbiological and organic contaminants in industrial wastewater was confirmed.
