Description
Изобретение относится к способам очистки сточных вод от металлов и может быть использовано для очистки сточных вод металлургических и горнообогатительных предприятий, гальванических производств.The invention relates to methods of purification of wastewater from metals and can be used for purification of wastewater of metallurgical and ore-dressing enterprises, electroplating industries.
Цель изобретения - повышение степени очистки сточных вод от ионов висмута.The purpose of the invention is to increase the degree of wastewater treatment from bismuth ions.
Способ осуществляют следующим образом.The method is as follows.
Сточные воды, содержащие висмут, подвергают обработке в анаэробных условиях активным илом, содержащим культуры сульфатвосстанавливающих (СВБ), метанообразующих (МОБ) бактерий и бактерий рода ЬерСоСЬггх при рН 4-5. В качестве биогенного питания используют отработанную смесь флотоагентов - продукта производства диоксана, содержащего одноатомные спирты пиранового и диоксанового ряда и гликоли.Wastewater containing bismuth is treated under anaerobic conditions with activated sludge containing cultures of sulfate-reducing (SRB), methane-forming (MOB) bacteria, and bacteria of the genus BocSbcx at pH 4-5. As a nutrient feed, a used mixture of flotation agents is used - a product of dioxane production, containing pyran and dioxane monohydric alcohols and glycols.
11 р и м е р. Биохимическую очистку сточных вод осуществляют· в установке, состоящей из емкости для куль· тивироззания микроорганизмов объемом 10 л, сырьевой емкости и отстойника. Процесс осуществляют -в течение 10 . дней непрерывно в анаэробных условиях при постоянной циркуляции активного ила. Скорость протока сточных вод 0,5 л/ч, температура 25-28°С, скорость перемешивания 60 об/мин.11 p and meer. Biochemical wastewater treatment is carried out in an installation consisting of a tank for the cultivation of microorganisms with a volume of 10 liters, a raw material tank and a septic tank. The process is carried out -in 10. days continuously under anaerobic conditions with a constant circulation of activated sludge. The flow rate of wastewater is 0.5 l / h, the temperature is 25-28 ° C, the mixing speed is 60 rpm.
В качестве транспортирующего газаAs a carrier gas
5 используют азот. В качестве базовых культур используют накопительные культуры сульфатвосстанавливающих, метанообразующих бактерий и бактерий рода ЬерСобЪгтх, выделенные из5 use nitrogen. As basic cultures, cumulative cultures of sulphate-reducing, methane-forming bacteria and bacteria of the genus Leopergium, isolated from
10 донного осадка пруда - накопителя сточных вод нефтехимического производства. Используемую смесь культур предварительно адаптируют к ионам висмута в течение 20 сут. Очистке10 bottom sediments of the pond - storage of wastewater from petrochemical production. Used a mixture of cultures pre-adapted to bismuth ions for 20 days. Cleaning up
