Description
Przedmiotem wynalazku jest sposób wykorzysta¬ nia scieków, zwlaszcza scieków powstalych w pro¬ cesach regeneracji jonitów uzywanych do zmiek¬ czania lub demdneralizacji wody.Dotychczas scieki powstajace w procesach rege¬ neracji jonitów uzytych do uzdatniania wody by¬ ly odprowadzane bezposrednio do kanalizacji. Scie¬ ki te zawierajace zwiazki chlorków wapnia i mag¬ nezu powodowaly szkodliwe zanieczyszczenia ka¬ nalizacji. Falowe spusty stezonych scieków powo¬ dowaly równiez niszczenie obudowy kanalów.Istota wynalazku jest sposób wykorzystania scie¬ ków z regeneracji jonitów polegajacy na tym, ze solanka zawierajaca" zwiazki wapnia i magnezu magazynowana w zbiornikach jest wprowadzana do zbiorników koagulacji scieków poprodukcyj¬ nych przemyslu wlókienniczego powodujac koagu¬ lacje tych scieków.Sposób wedlug wynalazku polega na tym, ze so¬ lanka uzyta do regeneracji zuzytych jonitów w procesie uzdatniania lub demineralizacji wody wy¬ mienia z jonitami jony sodowe na jony wapnia lub magnezu tworzac chlorki wapnia i magnezu.Solanke te magazynuje sie w zbiornikach a na¬ stepnie wprowadza sie do zbiorników koagulacji, przez które przepuszczane sa scieki poprodukcyj¬ ne przemyslu wlókienniczego, powodujac ich ko¬ agulacje, zastepujac stosowane dotychczas koagu¬ lanty.Sposób wedlug wynalazku pozwala wykorzystac zdolnosci koagulacyjne scieków z regeneracji Joni¬ tów. Pozwala to wyeliminowac uciazliwe operacje dotychczas specjalnie przygotowywanych srodków koagulujacych scieki przemyslu wlókienniczego.Sposób wedlug wynalazku pozwala uzyskac znacz- io ne odbarwienie scieków, zwieksza przezroczystosc do 30 cm, usuwa detergenty i zawiesiny zmniej¬ sza utlenialnosc i chemiczne zapotrzebowanie tle¬ nu, powoduje znaczne oszczednosci na srodkach i robociznie. Wynalazek znajduje zastosowanie w za- kladach posiadajacych stacje uzdatniania i demi¬ neralizacji wody i urzadzenia oczyszczajace scieki. PLThe subject of the invention is a method of using wastewater, especially wastewater formed in the processes of regeneration of ion exchangers used for softening or demineralization of water. Until now, wastewater produced in the processes of regeneration of ion exchangers used for water treatment were discharged directly to the sewage system. These sewage, containing calcium chloride and magnesium compounds, caused harmful contamination of the sewage system. Wave drains of concentrated sewage also caused the destruction of the canal lining. The essence of the invention is a method of using sewage from ion exchanger regeneration consisting in the fact that brine containing "calcium and magnesium compounds stored in tanks is introduced to coagulation tanks of post-production sewage The method according to the invention is based on the fact that the brine used for the regeneration of spent ion exchangers in the treatment or demineralization of water exchanges sodium ions with calcium or magnesium ions with the ion exchanger, forming calcium and magnesium chlorides. in tanks and stepping into coagulation tanks through which post-production sewage of the textile industry is passed, causing their coagulation, replacing the previously used coagulants. The method according to the invention makes it possible to use the coagulation capacity of sewage from ionite regeneration. This allows you to eliminate cumbersome operations d The method according to the invention allows to obtain significant discoloration of sewage, increases the transparency to 30 cm, removes detergents and suspensions, reduces oxidation and chemical oxygen demand, results in significant savings on resources and labor. The invention is applicable to plants having water treatment and demineralisation plants and sewage treatment plants. PL
