P Removal

This research aimed to investigate the phosphorus (P) removal of a series of laboratory-scale unvegetated vertical-flow constructed wetland systems using anthracite, steel slag and related blends as substrate in treatment of low concentration domestic sewage. The long-term performance of P removal was firstly studied by using single substrate of anthracite or steel slag, and three systems applying various combined substrates were investigated when the average P loading rate varied between 0.9 and 1.5 g TP/m2·d. The results demonstrated that both anthracite and steel slag systems were highly effective in removing total P (TP, 77.17 ± 23.34% and 90.26 ± 4.48%) and soluble reactive P (SRP, 92.14 ± 12.56% and 96.20 ± 2.58%). The system filled with anthracite, vermiculite and steel slag from the top down removed 82.45 ± 9.52% and 87.83 ± 8.58% of TP and SRP, respectively. However, other combined substrate systems showed comparative low and fluctuant P removal. The effluent pH was maintained at 7–9, which met environmental requirements of China. Therefore, anthracite provides a long-term high efficiency of P removal and may be a promising substrate from the standpoint of the effluent pH, and the arrangement of combined substrate has a prominent effect on P removal.

P Removal

The human waste concept of the Centre for Applied Ecology Schattweid, Switzerland combines treatment of feces in compost toilets and a constructed wetland for the liquid wastes. The wastewater of 5.1 population equivalents (greywater and urine) is treated in a two chambered settling tank followed by an underground vertical flow sand filter and a horizontal flow constructed wetland. The wastewater system has been in operation since 1985. Its performance has been monitored on COD, NH4-N, NO3-N, NO2-N, Total-P and Total-N almost monthly since then, and on other parameters (Total-Fe, Cl) occasionally. COD elimination (91.4 %) and Total-P removal (90.6%) were stable over the years, whereas NH4-N and Total-N elimination have improved markedly from around 55% to 93.0% (NH4-N) and 80.0% (Total-N). Performance in winter was excellent. The addition of an easily degradable carbon source to the plant filter in summer 1991 led to a markedly decreased phosphorus retention and a washout of iron during the experiment.
