Opis:: The pulp and paper industry is highly dependent on water for most of its processes, producing a significant amount of wastewater that should be treated to comply with environmental standards before its discharge into surface-water reservoirs. The wastewater generated primarily consists of substantial amounts of organic, inorganic, toxic and pathogenic compounds in addition to nutrients, which are treated in an effluent treatment plant that often combines primary, secondary, tertiary and advanced treatments. However, the treatment methods vary from industry to industry according to the process utilized. The effective performance of effluent treatment plants is crucial from both environmental and economic points of view. Radiotracer techniques can be effectively used to optimize performance and detect anomalies like dead zones, bypassing, channelling, etc. in wastewater treatment plants. Experiments on the distribution of residence time were performed on the aeration tank and secondary clarifier of a full-scale pulp and paper mill to study the flow behaviour as well as locate system anomalies and hence evaluate the performance of the treatment plants using the radiotracer I-131. The convolution method was applied to model the system with an imperfect impulse radiotracer input. The aeration tank was working efficiently in the absence of any dead zones or bypassing. Various hydrodynamic models available in the literature were applied on the aeration tank and secondary clarifier to obtain the hydraulic representation of the systems.

Opis:: This article discusses the main stages and features of wastewater treatment at “Food Ingredients” LLC (Russia, Krasnodar region) involved in vegetable oils and fats refining. The experimental data on averaged qualitative composition of industrial wastewater involving the period from January to June, 2018 were presented. The indicators of the quality of averaged waste did not exceed: 20 mg/l for ammonium nitrogen; 20 mg/l for phosphates; 800 mg/l for suspended solids; 700 mg/l for fatty substances. The operation of biological aeration tank was analyzed from January to June, 2018. The graphic dependences of the change of sludge index, phosphate ions, chemical oxygen demand (COD), and temperature were given. The species composition of microorganisms and their amount were determined by means of optical microscopy. Absolute quantity of microorganisms in activated sludge was determined with the “calibrated droplet” method. As of October 31, 2018 the quantity of microorganisms was as follows, U/ml: small flagellates – 44,015; free swimming infusoria – 34,233; Euglypha – 6,520; Vorticella – 27,713; Rotatoria – 29,343; Aspidiska – 36,950; Aelosoma – 2,173; Heliozoa – 1,086. No filamentous microorganisms were detected. After treatment, the recovered water was characterized by the following indicators of the quality: transparent, ammonium nitrogen content in water was less than 0.1 mg/l, phosphate ion content was no higher than 0.2 mg/l; COD was no higher than 30 mg O₂/l, hydrogen index was about pH = 7. These indicators comply with the requirements for water in technical water supply systems of industrial enterprises (Russia), as applied to recovered water produced of wastewater for subsequent use in recycled water supply system. The treated water is reused in the production processes, which evidences high quality of water treatment and reliable operation of the equipment in local treatment facilities at “Food Ingredients” LLC during 10 years of operation.

Opis:: W pracy omówiono przyczyny uszkodzeń ścian dwóch zbiorników – komór napowietrzania ścieków znajdujących się na terenie modernizowanej oczyszczalni ścieków w Grodzisku Wlkp. Zasadniczą przyczyną powstałych uszkodzeń było niewłaściwe rozmieszczenie dylatacji w ścianach zbiorników, zbyt małe zbrojenie poziome ścian niezabezpieczające ich przed wpływem skurczu betonu i zmian temperatury, zła jakość betonu oraz prowadzone roboty budowlane związane z budową w pobliżu nowego zbiornika. Po przeanalizowaniu kosztów naprawy zbiorników stwierdzono, że najbardziej racjonalnym rozwiązaniem będzie ich rozbiórka i budowa nowych obiektów z zachowaniem zasad współczesnej wiedzy technicznej, a do czasu podjęcia tych prac doraźne uszczelnienie spękanych ścian i ich lokalne wzmocnienie.
Present paper discusses the causes of damage of walls of two tanks – aeration chambers of wastewater located in the area of modernized sewage treatment plant in Grodzisk Wlkp. The main cause of the damage was improper location of dilatation in the tank walls, too low reinforcement of horizontal walls not protect them against the effect of concrete shrinkage and temperature changes, bad concrete quality and building work carried out near the new tank. After analyzing the costs of repairing tanks, it was found that the most rational solution would be their dismantling and construction of new facilities according to principles of modern technical knowledge. The temporary sealing of cracked walls and their local reinforcement will be applied until repair works are done.
