[Use of mycelial waste products as an additive in the manufacture of granulated active carbon].

The physico-chemical characteristics of type MAU active carbon manufactured with the use of the mycelial waste of tetracycline production and carbon residue are presented. Granulated active carbon MAU-5 was tested under laboratory conditions at the stage of the treatment of the antibiotic production waste. For the manufacture of the granulated active carbon the mycelial waste with the moisture content of 8 per cent and the carbon residue of weared tyres were used.

[The possibility for obtaining sorbents from the mycelial wastes of antibiotic production].

A technological process for production of a sorbent based on the mycelial waste of penicillin manufacture was developed. The process and its parameters are described. The exploitation conditions determine whether a strong sorbent with low sorption properties or a sorbent with higher sorption properties and lower granule strength is prepared.

[Assessment of the degree of electrochemical treatment of sewage using biotesting].

Studies were conducted on estimation of the toxicity levels in various oxygen-containing chlorine compounds formed during electrochemical treatment of sewage by using a culture isolated from activated sludge purifying antibiotic production waste. It was shown that the products formed during electrocatalytic treatment of solutions (concentration of NaCl 1.5-5 g/l, pH 2.

[Comparative evaluation of mathematical models of the process for the biological treatment of the wastes from antibiotic manufacture].

The main kinetic relationships of the process of biological oxidation of antibiotic production sewage were studied in laboratory models of mixer aerotanks. A relationship between the specific rates of BOD (biological oxygen demand) decreasing and BOD concentration in aerotanks was developed on the basis of the results relating to treatment of 8 types of the sewage within the ranges of the pure water BOD equal to 18-220 mg/l and the loads of 0.18-3.

[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.
