DEVICE
FOR BIOLOGICAL PURIFICATION OF STRONGLY POLLUTED INDUSTRIAL WATER WASTES
The device is intended for utilization of water
wastes.
The device is consists of:
- bioreactor-biofilter with biomass immobilized on
special carriers;
- filter for fine biological pre-purification of
air;
- filter for fine purification of water;
- other typical equipment required for
technological process.
The device represents local
installations permitting sharply decrease of pollutants with subsequent water
recycling.
Utilization of pollutions:
phenol and its nitro-chlorine derivatives; cresoles, xyloles, tolyene and other
aromatic compounds, acetone and complex ketones, alcohols and other solvents,
fatty acids, alkanes, oil and oil products, lubcicating-cooling liquids and oils,
vanishes and paints, etc. Purification degree up to 0,2-0,5 permissible
concentration. Water wastes polluted with heavy metal ions and R-nuclides (low
activity) are purified by more than 98%.
Peculiarities:
- availability certified stable
strains-biodesctructor associations;
- use of new generation of biosorbents and biomass
carriers;
- development of the technology taking into
account "individual" composition of water wastes;
- complex purification from primary and secondary
pollutions;
- simulation and scaling up of the process taking
into account inhibited metabolism of strain-associations under the conditions
of strong pollution.
Potential consumers:
chemical and oil industry, oil and gas exploration industry, machine engineering,
transport, energy, etc.
