Treatment of wastewater of malt factory with biohydrogen production
The developed technology of treatment of wastewater of malt factory from phosphates in the system of anaerobic-aerobic bioreac- tors with simultaneous biohydrogen production in bioelectrochemi- cal system is given in the paper.The biotechnological scheme contains the wastewater treatment blocks for the reduction of concentration of suspended substances, COD (chemical oxygen demand), phosphates and other environmen- tal pollutants, and also the bioelectrochemical system of biohydrogen production.The biotechnology, developed and approved in actual production conditions, provides high efficiency of wastewater treatment of malt factory from organic pollutants according to COD - 94-95 % at the values of COD indicator at the input up to 2000 mg/dm3, from phos- phates up to 90 % at the initial concentration of 25 mg/dm3.The application of bioelectrochemical method of hydrogen synthesis allows obtaining biogas consisting of 70 % of molecular hydrogen, and also provides the removal of organic pollution from wastewaters with the efficiency up to 98 %.
