Developing a complex technology for removing aromatic hydrocarbons from industrial wastewater and air
Summary
The issues of the treatment of industrial wastewater of a petrochemical plant at the biological treatment facilities are considered. The results of studies and pilot tests at a real-world object with a complex technology of removing aromatic hydrocarbons from industrial wastewater and waste air generated during wastewater treatment are presented. A fine-bubble aeration method with an efficiency of pollution removal 85–95% was proposed for wastewater treatment. The process of disposing of air generated during wastewater treatment in a biofilter is described in detail. It is shown that the most important condition of the efficient biological air cleaning is the stabilization of the chemical composition of wastewater; therefore, the relative measures have been proposed for the implementation of the process. It is stated that while observing the given condition, the efficiency of air cleaning in the biofilter can reach minimum 90% at the specific capacity up to 100 m3/(m2·h).
