Від 1999 року кафедра має назву "Хімічна техніка та промислова екологія", попередня назва – кафедра механічного устаткування хімічних виробництв.

Кафедра механічного устаткування хімічних виробництв була організована 18 жовтня 1946 року у складі факультету технології неорганічних речовин Харківського хіміко-технологічного інституту. Становлення кафедри пов’язане з іменами доцентів Георгія Веніаміновича Петрова, М. Ковальова, Абрама Натановича Цейтліна, Анісіма Рудольфовича (Рувиновича) Ястребнецького . У 1960 році на базі кафедри створено Факультет хімічного машинобудування.

Кафедра входить до складу Навчально-наукового інституту механічної інженерії і транспорту Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 2 доктора та 14 кандидатів технічних наук, 4 доктора філософії; 3 співробітника мають звання професора, 12 – доцента.

    The article deals with the intensification of flocculation wastewater treatment from finely dispersed suspended dust particles that are formed in the foundry shop at machine-building productions. The dependence of the floc sedimentation rate and wastewater clarification on solid phase concentration and flocculant flow rate was experimentally researched using model wastewater created by mixing dust and water. The multicomponent impurities of ionic flocculants on the aggregation process impact were experimentally proven, and anionic and cationic flocculants combination high efficiency was shown. The optimal parameters for the wastewater treatment process were established. The best flocculating effect and minimum flocculant consumption were observed at a solid phase concentration of 8-14 g/l. It was established that the most effective aggregate formation process is observed when two flocculants’ types are used simultaneously: anionic A-19 and cationic K-7, not each type separately. Flocculant flow rate experimental and calculated dependences for the wastewater treatment process depending on solid phase concentration and floc sedimentation speed necessary for effective sedimentation have been established. A technological scheme for wastewater treatment from suspended dust impurities that are formed in foundry shop at machine-building enterprise has been developed. The scheme includes: wastewater flocculation; water clarification in a sedimentation tank; and water deironing by aeration with coagulant addition and further filtration. It is proposed to use purified water in enterprise technological cycle that helps to reduce tap water consumption.

    The results of surface wastewater treatment of a machine-building enterprise from petroleum product contamination
    (National Institute of Research and Development in Mechatronics and Measurement Technique, 2024) Bosiuk, Alona; Shkop, Andrii; Kulinich, Serhii; Loboiko, Viacheslav; Sakun, Antonina; Shestopalov, Oleksii; Filenko, Olesya
    Petroleum pollution is an urgent and serious problem that has a negative impact on environmental safety and the state of the environment. Petroleum products that enter water resources cause a number of negative consequences, including water and soil pollution, reduced quality of natural ecosystems, as well as threats to biodiversity and human health. The purpose of this study is to assess the effectiveness of methods for treating surface wastewater of a machine-building enterprise from poll ution by petroleum products. In the course of the work, the results of cleaning the surface wastewater of the machine-building enterprise from pollution by petroleum products, samples of which were taken from the rainwater intake well at different depths – 30, 60 and 80 cm. A purification scheme has been developed and optimized, which includes the introduction of Al2(SO4)3 coagulant and A-19 flocculant into wastewater. Purification efficiency is achieved at about 95% at optimal reagent doses of 60-80 mg/L coagulant and 2-2.5 mg/L flocculant. The advantage of the conducted studies is the possibility of using the obtained data and methods for the analysis of wastewater with a similar composition of contaminants. It has been experimentally established that the simultaneous administration of reagents or the use of only one of them has lower efficiency and leads to insufficient purification of water from petroleum products. Neutralization of ion resistance contributes to the formation of coagulation structures, and to increase them it is recommended to use a flocculant to form and increase the size of aggregates. The results of the studies confirmed the prospect of using flotation to further separate the emerging petroleum flocculi, which allows to reduce the amount of reagents used and improve the efficiency of water treatment. The obtained data are important for practical application in the field of wastewater treatment from petroleum products at machine-building enterprises, contributing to the improvement of the quality of water resources and compliance with environmental safety requirements.
