“…Quantitative patterns of formation of the activated sludge ecosystem are dictated mainly by the technological mode of operation of aerotanks. As a rule, the total number of microorganisms is directly proportional to their oxidizing capacities, which is important for low-waste industries, especially for rural areas (Ibarruri, Hernández, 2021;López-Sánchez et al, 2022;Vishwakarma et al, 2022), where various devices can be used to collect algae biomass (Wang et al, 2022). The absence or insufficiently complete averaging of wastewater before it enters the aeration tank causes a complex of disturbing factors that negatively affect the efficiency of oxidation of organic pollutants in the aeration tanks.…”

Rational use of water resources is one of the urgent problems for arid regions of Kazakhstan. The biocenosis of activated sludge of urban wastewater treatment plants in Zhanaozen periodically encounters stressful situations associated with violation of the operating mode of equipment or emergency discharges of toxicants into the wastewater treatment plant system. It has been established that with sharp fluctuations in the physicochemical parameters of aqueous solutions, protozoal organisms are primarily eliminated from the composition of activated sludge. This pattern was noted with an increase in the content of ammonium nitrogen, phosphorus, monoethanolamine and pH fluctuations in wastewater. Under the conditions of a 10-month period of active insolation in Western Kazakhstan, the species diversity of the algoflora of activated sludge correlates with the duration of daylight hours; it was found that diatoms predominate in the autumn-winter period of the year, whereas blue-green and green algae predominate in the spring-summer period.
