By taking biological dye ponceau-G as tracer, the colorimetric method was adopted to analyze the effect of solution surface tension and spray methods on deposition rate of droplets on rice plants.

To conclude, the possible remediation technologies for this dye plant are biological remediation, landfill treatment, incineration, MCD, thermal desorption and etc.

In view of important role of biofilm in degradation of toxic refractory wastewater, the research USES a moving bed biological reactor to treat the dye industrial wastewater.
