ACTIVATED REACTANT SOLUTIONS, MODIFIED COAGULANT SOLUTION, COLLOIDAL OR SUSPENDED CONTAMINANTS , WASTE WATER, BIOLOGICAL ACTIVATION OF ACTIVE SLUDGE, FIXED BIOCENOSIS, BIOFILM, The object of the study is the process of treating natural and wastewater. The purpose of the work is to substantiate methods and technologies that allow increasing the efficiency of natural and wastewater treatment processes based on theoretical and experimental studies, creating mathematical models, determining optimal technological parameters, their feasibility study. The research method is a systematic and monitoring analysis of methods and technologies for treating natural and wastewater. Results and their novelty. There are presented studies on treatment of waste water from organic contaminants in aerotank-mixers with additional attached biomass. The proposed mathematical models, numerous and analytical methods of calculation using kinetic reactions according to the known Mono equation, make it possible to more reliably substantiate the parameters of wastewater treatment from OS in aerotank mixers. They also make it possible to evaluate the significant efficiency of the aerotenks by introducing an additional load with fixed biocenosis (biofilm). Method of biological activation of active sludge is investigated. The use of carboxylic acids for intensifying the work of urban sewage facilities is justified. During the production studies at the treatment facilities, it was established that: biological purification processes are intensified (by BNO5 - by 5.2%, by ChOC - by 4.5%, by ammonium nitrogen - by 8%, by phosphates - by 26.7%), sedimentation properties of the active sludge are improved (sludge index decreases from 300 ml/h to 120 ml/h) and the increase in the overhead index decreases/ Degree of implementation: the results of scientific research have been put into practice in the performance of master's works a Product Description popup.authors Airapetian Tamara S Galkina Olena P Dushkin Stanislav S Chub Irina M Shevchenko Tamara O popup.nrat_date 2021-01-13 Close
