The anaerobic baffled reactor (ABR)\u2013microbial fuel cell (MFC)\u2013microbial electrolysis cell (MEC) (AMM) coupling treatment system has been constructed achieving effective removal of carbon, nitrogen, and phosphorus from toilet sewage and resource recovery; however, ammonium (NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup>\u2010N) and total phosphorus (TP) accumulation in tail water is a found problem of the system. In this study, acid\u2010modified and alkali\u2010heat modified palygorskite\u2013bentonite (Pal\u2010Ben) were used to recover NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup>\u2010N and TP from the AMM toilet tail water simultaneously. The higher adsorption capacity of the modified clay is attributed to the changes of surface structure of the material. The modified clay Pal\u2010Ben (mass ratio 1:3) activated with alkali performed the highest NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup>\u2010N and TP recovery rates of 83.6% and 85.5%, respectively. The adsorption of NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup>\u2010N was more in line with the pseudo\u2010second\u2010order kinetic model and confirmed to be a chemical adsorption process, while the adsorption of TP was more in line with the pseudo\u2010first\u2010order kinetics and a physical adsorption process; the adsorption capacity of NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup>\u2010N accelerated with decrease of TP removal when pH increased. This study developed a low cost and high capacity of alkaline thermally modified clay removing\/recovering NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup>\u2010N and TP from toilet tail water simultaneously.<\/jats:p><\/jats:sec><jats:sec><jats:title>Practitioner points<\/jats:title><jats:p>\n<jats:list list-type=\"bullet\">\n<jats:list-item><jats:p>A cheap composite clay was developed to recover nitrogen and phosphorus from toilet tail water simultaneously.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>The low costs and high capacity of alkaline thermally modified clay make it stand out in NH<jats:sub>4<\/jats:sub><jats:sup>+<\/jats:sup>\u2010N and TP removal of toilet tail water.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>The process mechanism of simultaneous nitrogen and phosphorus recovery was clarified with characterization and kinetic model fitting.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>The used clay loaded with nutrients could be applied as a slow\u2010release compound fertilizer for soil improvement.<\/jats:p><\/jats:list-item>\n<\/jats:list><\/jats:p><\/jats:sec>","DOI":"10.1002\/wer.1495","type":"journal-article","created":{"date-parts":[[2020,12,11]],"date-time":"2020-12-11T05:52:54Z","timestamp":1607665974000},"page":"1077-1086","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Simultaneous recovery of ammonium and total phosphorus from toilet tail water by modified palygorskite\u2013bentonite clay"],"prefix":"10.1002","volume":"93","author":[{"given":"Shengguang","family":"Sun","sequence":"first","affiliation":[{"name":"School of Environment and Architecture University of Shanghai for Science and Technology  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guixia","family":"Ji","sequence":"additional","affiliation":[{"name":"School of Environment and Architecture University of Shanghai for Science and Technology  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yicheng","family":"Lv","sequence":"additional","affiliation":[{"name":"School of Environment and Architecture University of Shanghai for Science and Technology  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2672-7262","authenticated-orcid":false,"given":"Hongbo","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Environment and Architecture University of Shanghai for Science and Technology  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Hu","sequence":"additional","affiliation":[{"name":"Shanghai National Engineering Research Center of Urban Water Resources Co., Ltd.
