Four kinds of capping materials for controlling phosphorus and nitrogen release from contaminated sediment using a static simulation experiment
文献摘要：
We determined the effects of quartz sand(QS),water treatment plant sludge(WTPS),aluminum-based P-inactivation agent(Al-PIA),and lanthanum-modified bentonite(LMB)thin-layer capping on controlling phosphorus and nitrogen release from the sediment,using a static simulation experiment.The sediment in the experiment was sampled from Yundang Lagoon(Xiamen,Fujian Province,China),which is a eutrophic waterbody.The total phosphorus(TP),ammonium nitrogen(NH4+-N),and total organic carbon(TOC)levels in the overlying water were measured at regular intervals,and the changes of different P forms in WTPS,Al-PIA,and sediment of each system were analyzed before and after the test.The average TP reduction rates of LMB,Al-PIA,WTPS,and QS were 94.82,92.14,86.88,and 10.68％,respectively,when the release strength of sediment TP was 2.26-9.19 mg/(m2 d)and the capping strength of the materials was 2 kg/m2.Thin-layer capping of LMB,WTPS,and Al-PIA could effectively control P release from the sediment(P＜0.05).However,thin-layer capping of LMB,Al-PIA,and QS did not significantly reduce the release of ammonium N and organic matter(P＞0.05).Based on our results,LMB,Al-PIA,and WTPS thin-layer capping promoted the migration and transformation of easily released P in sediment.The P adsorbed by WTPS and Al-PIA mainly occurred in the form of NAIP.
