Claims (3)

1. Способ получения осветленной воды для питания водооборотных циклов аммиачного производства, заключающийся в заборе исходной воды, ее последующего осветления, коагуляции, флокуляции, фильтрации от механических и взвешенных частич и подачи на установку получения деминерализованной воды нанофильтрацией и обратным осмосом, отличающийся тем, что в качестве исходной воды используют биологически очищенные сточные воды химического производства, ливневые стоки, шахтные сточные воды и другие стоки или их смеси с общим солесодержанием 3÷4 г/л, содержанием взвешенных веществ до 50 мг/л с общим микробным числом до 10 тыс. ед. в мл, с общей жесткостью до 15 мг-экв/л, воду предварительно очищают на сетчатых фильтрах 200 мкр., осуществляют осветление воды путем ультрафильтрации, проводя процесс разделения от растворенных примесей на ультрафильтрационных мембранах со спектром фильтрации от 50 до 1000 ангстрем при давлении 0,05-0,5 МПа до полного устранения взвешенных веществ в пермеате, задержания всех микробиологических загрязнений.1. The method of obtaining clarified water for feeding the water circulation cycles of ammonia production, which consists in taking the source water, its subsequent clarification, coagulation, flocculation, filtration from mechanical and suspended particles and feeding the plant for receiving demineralized water with nanofiltration and reverse osmosis, characterized in that as the source water use biologically treated chemical wastewater, storm sewage, mine wastewater and other effluents or mixtures thereof with a total salinity of 3 ÷ 4 g / l, suspended solids up to 50 mg / l with a total microbial number of up to 10 thousand units. in ml, with a total hardness of up to 15 mEq / l, water is preliminarily purified on 200 micron strainers, the water is clarified by ultrafiltration, and separation from dissolved impurities is carried out on ultrafiltration membranes with a filtration spectrum from 50 to 1000 angstroms at a pressure of 0 , 05-0.5 MPa to the complete elimination of suspended solids in the permeate, retention of all microbiological contaminants. 2. Способ по п.1, отличающийся тем, что в качестве флокулянта используют хлористое железо FeCl3 (14%).2. The method according to claim 1, characterized in that iron chloride FeCl 3 (14%) is used as a flocculant. 3. Способ по п.1, отличающийся тем, что проводят очистку мембранных элементов путем подачи и выдержки по времени моющих растворов: серной кислоты (50%) и щелочи (42%) или гипохлорита натрия (20%).3. The method according to claim 1, characterized in that the membrane elements are cleaned by feeding and soaking in time washing solutions: sulfuric acid (50%) and alkali (42%) or sodium hypochlorite (20%).
