Technology introductionEC multistage biochemical combination process of coal chemical industry wastewater treatment technology, can be applied in coal gas, coal, and coking coal chemical industry wastewater treatment field, EC of the combined period of biochemical reactor with high organic load, hydraulic retention time is short, cover an area of an area small, less infrastructure investment, energy consumption and operation cost is low; Easy operation and management, simple maintenance, good effluent water quality, with good phenol and ammonia nitrogen removal ability; Strong process stability, flexible operation mode, combined process start speed, high degree of automation of process equipment advantages. High degree of automation, stable processing effect, low operating cost advantages.
Technical advantagesEfficient removal of typical pollutants in coal chemical wastewater -- polyphenol efficient removal of polycyclic aromatic compounds, heterocyclic compounds and cyanide and other toxic and harmful substances. Efficient removal of ammonia nitrogen, effectively reduce effluent chroma.
Application scenariosZero discharge of high phenol ammonia wastewater from coal chemical industry
