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 *** sediment in the experiment was sampled from Yundang Lagoon(Xiamen,Fujian Province,China),which is a eutrophic *** 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 *** 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/(m^(2)·d)and the capping strength of the materials was 2 kg/m^(2).Thin-layer capping of LMB,WTPS,and Al-PIA could effectively control P release from the sediment(P0.05).Based on our results,LMB,Al-PIA,and WTPS thin-layer capping promoted the migration and transformation of easily released P in *** P adsorbed by WTPS and Al-PIA mainly occurred in the form of NAIP.

This study focuses on the effectiveness of hydrous manganese dioxides （ζMnO2） removing arsenite （As（Ⅲ）） from aqueous solution. Effects of such factors as permanganate oxidation, pH, humic acid and Ca^2＋ on As removal and possible mechanisms involved in have been investigated. Permanganate oxidation increases As removal to a certain extent; the higher pH results in the formation of more easily adsorbed As species, contributing to higher As removal; hmnic acid occupies adsorbing sites and decreases ζ potential of ζMnO2, therefore inhibiting As removal; Ca^2＋ facilitates As adsorption on ζMnO2, mainly through increasing ζ potential and decreasing repulsive forces between As and surface sites.ζMnO2 exhibits oxidative and adsorptive potential for As（Ⅲ）, and may be employed as adsorbents or filter coating for As removal in water treatment process.

以江苏扬州古运河富营养化水体为对象,现场围隔实验研究生物沸石薄层覆盖削减富营养化水体磷负荷可行性,考察生物沸石覆盖削减上覆水、底泥间隙水和底泥中不同形态磷的削减效果,讨论生物沸石覆盖修复过程中不同形态磷转化机制.结果表明,覆盖强度为2 kg/m2的生物沸石覆盖（厚度约2 mm）对上覆水中总磷的削减率为57.41%,对上覆水中正磷酸盐的削减率为60.03%;对底泥间隙水中正磷酸盐的削减率为59.80%;对表层底泥（0~20 cm）中总磷削减率为11.28%,对无机磷削减率为11.82%,对有机磷削减率为11.11%.生物沸石覆盖能将底泥中不稳定的无机磷（可溶性磷、铁结合态磷、铝结合态磷）或少部分较稳定的无机磷（钙结合态磷）转化为稳定的无机磷（包裹磷）,说明生物沸石覆盖不仅能削减液相中磷负荷,而且能将固相中不稳定的无机磷转化为稳定的无机磷;可见,生物沸石薄层覆盖能有效削减富营养化水体磷负荷,利用生物沸石薄层覆盖削减富营养化水体磷负荷是可行的,但需要进一步研究富营养化水体底泥生物薄层覆盖修复过程中不同形态无机磷转化机制.
