Biological Contact Oxidation

The lab scale biological fosfomycin degradation by hydrolysis acidification-contact oxidation combined process was studied. And the microbial communities in hydrolysis acidification-contact oxidation combined process were analyzed. The results showed that the organic phosphorus was well degraded by hydrolysis acidification-contact oxidation combined process when organic phosphorus concentration in the influent was lower than 10 mg/l. The combined process could endure the loading with the influent organic phosphorus concentration between 10-20 mg/l. The community analysis showed that most of the phosphorus removal bacteria and antibiotics resistance bacteria were discovered in contact oxidation.

Phosphorus Contamination

Phosphorus contamination in aquatic system was a widespread problem in Zhejiang province due to the excess use of detergent, agrochemicals and other organic phosphorus chemicals. Volcanic rock, an adsorbent with porous structure and large surface area, was applied for phosphorus removal in wastewater. The results showed that the phosphorus removal rate and equilibrium time had positive correlation with the initial phosphorus concentration, while the volcanic rock particle size could also affect the adsorption performance as volcanic rock with smaller particle size used to have a larger cation exchange capacity and higher surface area. Both Langmuir adsorption and the Freundlich adsorption happened throughout phosphorus removal process, showing the strong capacity and capability of volcanic rock as absorbent for phosphorus wastewater. It is promising to use volcanic rock in phosphorus water/wastewater purification systems due its large quantities and accessibility in nature.
