The purpose of work: Long-living natural and technical radionuclides, heavy metals will be regularly examined for their removal particularities from humic containing water environments and for development of a physic-chemical basement of complex purification circuit with use of various ways. Method of research: physic-chemical (photometric, baromembrane, sorption, coagulation) with use of b-radiometer KRK 1-01A, photometer KFK-2MP, ultrafiltration installation, pH-meter EV-74 and others. The basic results: humic containing radiopolluted waters were purificated by various methods as follows: sorption one employs natural alumosilicates, biocenos and active silt, coagulation one with use of iron and aluminium salts as coagulants, baromembrane ones (revere osmosis and ultra filtration). The physic-chemical substantiation of each method of clearing is carried out, the optimum conditions of radionuclides removal are found, the influence of the different factors on the mechanism of removal and efficiency of clearing of water is considered.Areas of application: for clearing the large volumes of water supply sources at limit concentration excess of long-living toxic radionuclides for drinking and economic purposes, for purification of the waste water, which turn out at peace use of an atomic energy and at emergencies.
