The object of the study is the wastewater of the stormwater treatment facilities №54 owned by "Motor Sich" PJSC. The purpose of research: determining the feasibility of using environmental biotechnology consisting of fixed immobilized microhydrobiocoenoses for the treatment of plant's industrial discharge waters. As a result of our work, we have determined that on the surface where the fiber carriers are being developed the "rafts" installed at the stormwater treatment plants №54 of the "Motor Sich" JSC formed an advanced microhydrobiocenosis characterized by high species diversity and quantity, which contributes to the intensification of the biological process of purification of the plant's wastewater. The level of fouling of fiber contact carriers at the plant's treatment facilities studied during a given period (from spring to autumn) ranged from 2,210 copies per ml to 34,992 copies per ml. High rates of zoocenosis density were mainly due to the growth of infusoria, the average number of which was 8409-13403 per ml. According to the results of biological water treatment, it was determined that the purification of wastewater from petroleum products in the experimental channel using 76 floaters ("rafts") with fiber carrier at the end of the channel was at the level of 58.7-72.5%. In the control channels, without the use of a fiber carrier, the degree of water purification from petroleum products at that period was at the level of 0.0-26.4% (with the addition of "Ecolan" adsorbent). The efficiency of purification of wastewater from petroleum products in the experimental channel with fiber carrier on release after the claydite loading was at the level of 80.54-91.65%. In the control channels (without the use of a fiber carrier), the degree of water purification from petroleum products on release after the loading at that period was at 6.22-46.87% (with the addition of "Ecolan" adsorbent). That is, the given data confirms that the use of fiber carrier "VIYA" for the purpose of purification of wastewater from petroleum products is 2.7 times more efficient than the purification of the same water using conventional methods. The novelty of this work lies in the fact that during a period from spring to autumn the use of "VIYA" fiber carrier as an agent for purifying the plant's sewage from oil products has been studied for the very first time. "VIYA" fiber carrier can be used by industrial enterprises and utility companies for a more efficient wastewater treatment. Field of application: biotechnology of water purification.
