碩士 === 嘉南藥理科技大學 === 環境工程與科學系 === 101 === Taiwan's drinking water quality standards are not currently set given aluminum content limits, EPA is one of the objectives have been included in the quality of drinking water contaminants for screening, According to the research results, part of the water purification plant in the water distribution mainsthe network included in the total aluminum concentrations exceeding 0.2 mg / L. Nan jade water purification plant, the research for the study, conduct on-site investigations to operating technical documents and the establishment of the assessment tasks on the field with major unit operations assessment, the main unit of this field, the project contains the raw water quality characteristics, coagulation / gelling unit specifications, coagulant type and usage, coagulation / gelation unit operating conditions. Draw new dosing bottle cup test results according to the turbidity of the research carried out under the curve updated the dosing curve to reduce the total residual aluminum content. Add another two ferric chloride in a sink of water purification water treatment and water unit unit only in the submerged unit of more than 0.2 mg / L, two other water treatment and water unit residual aluminum volume of less than 0.05 mg / L. Via Nan jade water purification plant ferric chloride dosing trial results found that the switch to ferric chloride coagulant can reduce the amount of residual aluminum in the water.
