Total Nitrogen Removal

The presence of 2 and 5 mg L−1of tetracycline decreased total nitrogen removal. Tetracycline induced EPS release and decreased its protective role on cells. Denitrifiers instead of nitrifiers were negatively affected by tetracycline.

Floating Plants

This study focused on the comparisons between nitrogen and phosphorus removal rates from the simulated wastewater using various kinds of aquatic plants (4 emergent and 3 floating plants). Results showed that aquatic plants has a significant effect on the removal of NO3--N and TP, but has a less effect on NH4+-N. Among the four emergent plants, the order of NO3--N removal capacities was: S. sagittifolia > S. tabernaemontani > T. latifolia > A. calamus. But for TP, the order was: T. latifolia > A. calamus > S. tabernaemontani > S. sagittifolia. To the floating plants, the order of NO3--N and TP removal capacities were: E. crassipes > P. stratiotes. The ANOVA analyses showed that there was a significant difference between planted treatments and unplanted treatment for the removal of NO3--N and TP. The study suggests that the treatment of simulated wastewater using the aquatic macrophytes was effective in the removal of nutrients.

Urban Landscape Water

The bioremediation technology for urban landscape waters are illustrated in this paper. The characteristics and purification performance of urban landscape waters were introduced. Based on their good effects on nitrogen and phosphorus removal, the landscape plants are recommended as species of aquatic vegetation in phytoremediation of wastewater of urban river.

Denitrification Process

For the sewage treatment plants near rivers and closed water bodies in urbanized areas there is a growing demand for introduction of advanced treatment processes for nitrogen and phosphorus removal for water quality conservation and environmental protection. In order to achieve the total nitrogen content of below 10 mg/L in effluent, a compact single sludge pre-denitrification process by dosing immobilized pellets in the nitrification tank (PEGASUS process) has been already developed (Tanaka et al. 1992). Furthermore, a two-stage PEGASUS process and a PEGASUS process with post-denitrification were developed and investigated for nitrogen removal. Both processes achieved the total nitrogen of less than 5mg/L.

Oxic Zone

In this research, the domestic wastewater was treated by full-scale Biolak/A2O process. The effects of dissolved oxygen (DO) on nitrogen and phosphorus removal of the system in oxic zone were investigated. Controlling to DO at 0.8-1.5 mg/L, the treatment efficiency of system was near optimal with the total nitrogen efficiency of 69.45%. The simultaneous nitrification and denitrification could be achieved under this condition. Based on the calculation equations and transformation pathways of nutrients, about 23.71% total nitrogen (TN) was removed by multistage A/O system in the oxic tank. When DO was 1.0-3.0mg/L, the total phosphorus (TP) removal efficiency was the highest at 73.97%. DO in the range of 1.0-1.5mg/L was optimal for the nutrient removal in Biolak/A2O process, removal efficiency of TN and TP were 68.87% and 73.68%. TN and TP of the effluent were 12.02mg/L and 0.95mg/L, respectively.
