Improving Nutrient Removal in Constructed Wetland Wastewater Treatment

The percentage pollutant removal obtained by the previous work were very good in terms of BOD5 which was 95% removal, TSS 97% but unsatisfactory NH4-N, NO3-N and P 39%, 41% 44% respectively-The effect recycling portion effluent discharged from 2ND. Cell, a VSSF constructed wetland back to 1ST. cell on nutrient efficiency studied this research.The intermittent feeding influent recycled quantity had system aeration dissolving air trapped voids substrates before each doss using it activate aerobic bacteria.The Nitrification denitrification enhanced process. Recycling with low BOD & COD when mixed raw wastewater infeed will increase helps nitrification process most oxygen has been consumed, microorganisms during biological chemical degradation pollutant, than start transfer NO3-, ultimately, N2 gas.The hydrology condition good, water running laminar form detention time highest July lowest January as expected due evapotranspiration reaches its January.The maturity reed plant extension their stems roots may have positive influence on:- Aerobic required for supplying more outside atmosphere system.- Adsorbing heavy metal ions extended plant.- Increased uptake plants results lowering effluent.
