Abstract
Изобретението се отнася до метод за отстраняване на фосфор, намиращ се под формата на ортофосфат, от водни системи. По него се въвежда в потока ефективно количество калциеви йони, за предпочитане получени от гипс. рН се настройва на 5-8 и потокът сеподава в реакционен съд, където се привежда в контакт с внимателно разбъркван слой от фини частичкимагнезиев оксид в количество, достатъчно да задържи така образувания калциев фосфат. рН на потока при контакта му с магнезиевия оксид е от 8 до 12, след което обеднелият на фосфор поток се отвежда отсъда.The invention relates to a process for the removal of phosphorus, in the form of orthophosphate, from aqueous systems. An effective amount of calcium ions, preferably made from gypsum, is introduced into the stream. The pH is adjusted to 5-8 and the stream is sucked into a reaction vessel where it is brought into contact with a carefully stirred layer of fine magnesium oxide particles in an amount sufficient to retain the calcium phosphate thus formed. The pH of the contact with magnesium oxide is from 8 to 12, after which the phosphorus-impoverished stream is removed from the reactor.
