Kharkov technikal university of construction and architecture popup.description2 The study is to develop a methodology of process management biochemical transformation of nitrogen, phosphorus and sulfur compounds in wastewater transported sewerage network and processed at wastewater treatment plants, and accompanied by the formation of dissolved and gaseous substances in an environmentally hazardous concentrations. Object is a biochemical process that make compounds of nitrogen, phosphorus and sulfur in plants diversion and wastewater treatment. The subject of research is the management process of converting nutrients transportation and purification of wastewater. Scientific novelty of the research results: first, according to laboratory tests, based on calculations using mathematical models proposed by the authors and multiplicative dependence, dependency set quantitative accumulation of hydrogen sulfide in wastewater by simultaneous action of three independent factors - temperature waste water, its ORP and duration of exposure; determined that when the temperature of waste water, which provides the heat pump, the accumulation of H2S in the atmosphere decreases underroofing space collectors ~ 50%. For the first time the technique of determining the environmental hazard class and operational reliability of individual mines / wells and sewage networks created and protected by the copyright certificate computer program "Monitoring of gaseous emissions from sewage networks" First in experimental studies defined quantitative inhibitory effect on the removal of ammonia nitrogen (nitrification wastewater) Organic Compounds (with integral indicator COD and individual zarudnen - oil, phenol and sleeping) compounds and other nutrients - phosphorus and sulfur; set quantitative impact on phosphatase wastewater occurs in the secondary clarifiers, concentrations of nitrates and processing methods, and defined inhibition constant phosphatated nitrates; Based on research on a pilot installation of improved mathematical model of removing organic substances and nitrogen oxide sludge growth and consumption of dissolved oxygen in circulation-oxidative channel. The significance of the results is: defined efficiency of the heat pump to the sewer network to reduce the accumulation of H2S in the atmosphere of underroofing space collectors; recommendations automation monitoring systems of gaseous emissions from sewage networks and computer program "Monitoring of gaseous emissions from sewer networks," which allows map and implement accounting sanitation facilities, visualize areas of the network to prioritize the need for facilities implementing environmental events; established process parameters wastewater treatment needed to intensify their treatment of nutrients to the biological wastewater treatment plants in the system of aerotanks-tank, as well as small treatment plants - circulation-oxidative channel (COC).
