A combined process which included acidification precipitation,iron-carbon reduction,air stripping and two phase A/O process was used in treatment of wastewater from pathalocyanine production,through the research,the optimized parameters of every units were determined.

This paper do research on the effect of pH value,concentration of wastewater and retention time on the removal rate of dyeing by iron-carbon microelectrolysis method(including static experiment and dynamic experiment).

In order to solve the problem that traditional iron-carbon electrolysis technology would causes consolidation during waste water treatment after operation for a time, which reduces efficiency, this study presents dual-electrode reductive method by iron-carbon and design a new dual-electrode devise of electrode reductive method.

Highly concentrated and biorefractory surfactant wastewater treatment research with ferric-carbon method;
