Viewpoint　of　substituting　disinfection　function　of　disinfectant　by　controlling　phosphorus　content　to　restrain　bacteria　growth　is　advanced,　according　to　the　key　action　of　phosphorus　in　microorganism　growth　and　a　series　of　water　quality　problems　caused　by　drinking　water　disinfection　process.　Feasibility　of　the　viewpoint　in　practice　and　research　to　carry　out　are　analyzed　in　the　respect　of　existing　monitoring　method　of　phosphorus　and　phosphorus　removal　effect　of　conventional　treatment　process.　It　is　pointed　out　that　these　will　be　a　field　of　advanced　phosphorus　removal　from　drinking　water,　by　development　of　new　and　highly　effective　coagulants　and　special　adsorbents　with　advantage　of　phosphorus　removal,　on　condition　that　existed　treatment　process　is　not　changed.
