The proposed book contains basic information about wastewater from coke-chemical plants, the sources of their formation, mechanical, physico-chemical and biochemical methods of treatment, principles of wastewater certification.

Modern technological schemes of biochemical plants are considered in detail. In the form of technological instructions, the stages of startup, adjustment and operation of biochemical installations, breeding microbial cultures from the laboratory to industrial aeration tanks are described.

Schemes for technological and analytical control of the operation of biochemical installations are described.

Particular attention is devoted to consideration of the principles of creating a drainless coke-chemical production and analyzes the results of the use of treated wastewater in industrial recycling water supply.

The monograph summarizes more than twenty years of experience in research, commissioning, commissioning and operation of biochemical plants of coke-chemical production in Russia and near and far abroad .

The book is intended for engineering and technical workers of enterprises involved in the issues of certification, purification and use of phenolic wastewater, as well as for operating personnel of treatment facilities of coke production plants.

The book will be useful to university students and secondary technical educational institutions.
