Abstract

According to the World Health Organization, human diseases caused by consumption of low-quality water can account for up to 80% of the total number of health problems. In general, more than half of the world population consume low-quality water, and thus every third inhabitant is endangered by gastrointestinal diseases. Economic damage from morbidity of the population using low-quality water virtually cannot be measured to the full extent due to specifics of the problem and incomplete initial data. Nevertheless, one can say with certainty that this component predominates in the total amount of damage from pollution of water sources.

Sewage of enterprises contain oil products, heavy metal ions, and many different chemical compounds. Harmful chemical elements and substances enter water bodies worsening their sanitary condition, which requires thorough water treatment before using it for household and drinking purposes and for some industrial purposes.

With the growth of technological productions, there is an urgent need to clean up wastewater, which contains petroleum products, heavy metal ions, and many different chemical compounds. Today, there are quite a few efficient technological methods for cleaning up such contaminants, but all these methods clearly depend on the degree of cleaning up on the costs incurred for this process, therefore, in the real economy these methods are used selectively or partially due to the substantial cost of these methods.

The environmental problems of wastewater treatment are considered in papers of Alekseev M.I., Vinogradov S.S., Gubanov L.N., Ilyin Yu.A., Evilevich A.Z., Zainullin Kh.N., Zapolsky A.K., Koganovsky A.M., Kudryavtsev V.N., Ksenofontov B.S., Naidenko V.V., Palgunov P.P., Smirnov A.D., Tarasevich I.Yu., Yakovlev S.V. and others.

The use of natural materials for wastewater treatment is reasonable from the environmental and economical perspectives even though such materials do not offer necessary sorption properties without being modifed or nano activated. Due to modification or nano-activation, the sorbent surface takes on new properties and combines useful properties of the original mineral and synthetic sorbents. In spite of broad applicability of sorption methods and procedures in industrial wastewater treatment, there is a number of problems in this field. The most critical problems are insufficient sorption capacity of materials, lack of reliable sorbent recovery techniques, sustainable treatment technology which uses sorbents, methods of recycling heavy metals using complex formation.

In this paper, a technique of wastewater treatment from heavy metal ions using nanoactivated complexes of natural zeolite and diatomite is proposed. This technique can reduce significant costs in preparation of raw materials and its subsequent chemical modification. Technological solutions are proposed for disposal and recycling of industrial wastewater allowing obtaining water treated to the necessary regulatory water content of impurities and returning it to the process cycle. The uniqueness of the method and techniques is in the use of nanoactivated natural sorbents for treatment of both ion-exchange water, and also natural water from heavy metal ions that pollute it.
