В электроламповой npoivbUiuieHHocти в виде отходов производства сбрасываютс в канализацию кислые растворы , содержащие молибденовые соли, азотную и серную кислоты.In the electrolamp npoivbUiuieHHosti in the form of production waste acidic solutions containing molybdenum salts, nitric acid and sulfuric acid are discharged into the sewer.
Цель изобретени - использование указанных отходов и получение ценных дл сельскохоз йственного хоз йства микроудобрений.The purpose of the invention is the use of these wastes and the production of micronutrients that are valuable for agricultural use.
Дл этого в качестве исходного сырь примен ют воды спирального производства электроламповойпромышленности , содержащие молибден, азотную и серную кислоты.For this purpose, water from spiral production of the electric lamp industry containing molybdenum, nitric acid and sulfuric acid is used as a raw material.
Способ осуществл ют следующим образом.The method is carried out as follows.
Отходы спирального производства собирают в кислотостойкую тару,, например из винилпласта. Осажде- . ние солей из отработанного раствора производ ;т жидким распыленным аммиаком . Небольшое количество насыщенной жидкости до 5%) на поверхности осевших кристаллических солей сливают и подвергают выпариванию до сухого кристаллического продукт. Осажденный продукт (95%) имеет первоначальную влажность до 30% и легк поддаетс сушке до требуемой влажности . Из 1 л отработанных вод спирального производства получают 1,3 кг смеси солей с влажностью до 10%.Spiral production waste is collected in acid-resistant containers, for example, from vinyl plastic. Precipitated salt from the spent solution is produced by liquid ammonia sprayed. A small amount of saturated liquid (up to 5%) on the surface of precipitated crystalline salts is drained and evaporated to a dry crystalline product. The precipitated product (95%) has an initial moisture content of up to 30% and is easy to dry to the desired moisture. 1.3 kg of a mixture of salts with a moisture content of up to 10% is obtained from 1 l of wastewater from the spiral production.
Компоненты смеси вз ты в следующем соотношении, вес.%:The components of the mixture are taken in the following ratio, wt.%:
10ten
4040
5050
Расход жидкого аммиака на 1 л отработанных вод составл ет около 0,4 кг, продолжительность осаждени солей 5-6 ч.The flow rate of liquid ammonia per liter of wastewater is about 0.4 kg, the duration of the precipitation of salts is 5-6 hours.
Полученна смесь солей представл ет собой микроудобрение, которое по зaключeниJo УНИХИМ может быть использована в сельском хоз йстве как азотное удобрение, содержащее нитратный и аммиачный азот. Наличие в смеси молибдата аммони позвол ет применить ее как удобрение дл бобовых культур.The resulting mixture of salts is a micronutrient, which can be used in agriculture as a nitrogenous fertilizer containing nitrate and ammonia nitrogen. The presence of ammonium molybdate in the mixture allows it to be used as a fertilizer for legumes.
Кроме, того, реализаци способа полезна с точки зрени обезвреживани кислых сточных вод. In addition, the implementation of the method is beneficial from the point of view of neutralizing acidic wastewater.
