Abstract

Inventia se refera la un procedeu de purificare aapelor de nitriti si poate fi utilizata in procesul de tratare a apelor de suprafata si de mina la statiile de epurare sau pentru purificarea apei inconditii casnice. Procedeul consta in aerarea apei in prezenta carbunelui activ, totodata se utilizeaza carbune activ granulat ŔĂ-5, aerarea apei se efectueaza timp de 120...180 min, cu un debit de aer de 0,7...0,8 L/ora la 100 g de carbune activ, iar raportul masic carbune activ : apa este de 1 : (9...10).The invention relates to a process for the purification of nitrite water and can be used in the process of treating surface and mine waters at wastewater treatment plants or for purifying domestic waste water. The process consists of aerating the water in the presence of the activated carbon, at the same time the granulated activated carbon uneĂ-5 is used, the aeration of the water is carried out for 120 ... 180 min, with an air flow of 0.7 ... 0.8 L / hour to 100 g of activated carbon, and the mass ratio of activated carbon: water is 1: (9 ... 10).
