[Electrochemical treatment of the waste waters from the manufacture of endocrine preparations].
An approach to intensification of biological treatment of industrial sewage containing liquid wastes of endocrine drug production is described. The most contaminated effluent of rectification columns is isolated from the general plant discharge and subjected to local treatment. The advisability and level of the local treatment in electrochemical sewage treatment were studied under laboratory conditions. At the current density of 220 A/m2, the process time of 10 min at pH 6.0 and the ratio of the local effluent to the general plant discharge of 1:30 the level of the sewage treatment was the following: 45-50 per cent by the chemical demand of oxygen and 50-60 per cent by the biological demand of oxygen in 5 days. The residual content of active chlorine did not exceed 14 mg/l. It was shown experimentally that during the sewage treatment there formed no compounds toxic for the activated sludge microorganisms.
