Abstract
Due to the opening of a large number of industrial enterprises, one of the urgent problems is the purification of industrial waters and waste recycling. In connection with the reduction of environmental conditions, there is a need to tighten the requirements for the discharge of industrial wastewater and waste. Currently, the methods of wastewater discharge have been changed. In addition, there are requirements for the development of effective approaches in the field of industrial wastewater treatment. The main purpose of the research work is the wastewater treatment of OC "Kainar-AKB" from toxic metal ions using natural adsorbents. According to the study of wastewater treatment by OC "Kainar-AKB" bentonite montmorillonite (Sredny Tentek), red bentonite (Mukry), zeolite (Maytobe) and diatomite (Ile) were taken as natural adsorbents. To determine the chemical composition of the studied objects, an X-ray phase analysis was carried out. As a result of qualitative and semi–quantitative analysis of minerals, it was found that the main component of diatomite is SiO2, in cyolite - the content of Laumontite Ca4Al8Si16O48·14h2o (51.3%). As a result of the study, it was found that natural minerals from the Almaty region have sorption properties, that is, they can be used to purify all industrial wastewater. Since the results obtained exceeded the MPC standards for wastewater, it can be recommended to use these sorbents in wastewater treatment processes along with other methods (reagent, biological, etc.).
