Description

ет процесс взаимодействи  фторида аммони  с карбонатом кальци . Кроме того, исключаетс  необходимость отстаивани  (или фильтровани ) шлама кальциевых солей.The process of interaction of ammonium fluoride with calcium carbonate. In addition, the need to uphold (or filter) the calcium salt sludge is eliminated.

Парогазовую смесь, образующуюс  на первой стадии, подвергают затем каталитическому разложению при 400- бООС в присутствии никелевого катализатора . При этом происходит раа ложение аммиака на азот и воду.The vapor-gas mixture formed in the first stage is then subjected to catalytic decomposition at 400-BOOC in the presence of a nickel catalyst. In this case, ammonia is affected by nitrogen and water.

Пример. Сточную воду в количестве ОД л, содержащую аммиак и фториды аммони , подвергают термической обработке в никелевой трубкеExample. Sewage water in the amount of OD l containing ammonia and ammonium fluoride, is subjected to heat treatment in a nickel tube

сначала в присутствии карбоната кальци  при затем в присутствии никел  при 300-700 С.first in the presence of calcium carbonate with then in the presence of nickel at 300-700 C.

При этом масса карбоната кальци  5-8 г; размер частиц карбоната кальци  0,1-2,0 мм; скорость подачи раствора 0,1 л/ч; катализатор - никеле вые кольца диаметром 4 мм,The mass of calcium carbonate is 5-8 g; calcium carbonate particle size 0.1-2.0 mm; the feed rate of the solution is 0.1 l / h; catalyst - nickel rings with a diameter of 4 mm,

. Далее парогазовую смесь охлаждают при 20-25 С и получают 0,1 л конденсата .. Next, the gas-vapor mixture is cooled at 20-25 C and receive 0.1 l of condensate.

Результаты очистки, уточных вод, содержащих аммиак и фтористый аммоний, путем термической обработки представлены в таблице.The results of purification, weft waters containing ammonia and ammonium fluoride, by heat treatment are presented in the table.
