The　three　concepts　of　composition　parameter,　process　parameter　and　technological　parameter　were　put　forward　for　the　first　time　according　to　the　characteristics　and　rules　of　the　reaction　period　in　the　SBR　process　in　this　article　in　order　to　analyse　deeply　the　correlativity　and　relation　among　these　parameters,　put　forword　better　process　control　strategies,　estimate　the　existing　state　and　quantity　of　the　composition　parameter　according　to　the　variety　rule　characteristics　of　the　process　parameter,　control　and　regulate　the　technological　parameter　of　the　SBR　process.Based　on　the　three　concepts　of　composition　parameter,　process　parameter　and　technological　parameter,　and　on　the　existing　researches,　the　movable　change　of　COD,　DO,　ORP　and　pH　curve　in　the　process　of　the　organic　pollutant　degradation　in　the　SBR　process　were　summarized　systematically.　The　relation　between　the　composition　parameter　COD　and　the　process　parameter　DO,　ORP,　pH　and　the　relation　among　the　process　parameter　DO,　ORP,　pH　were　discussed.　The　feasibility　of　making　use　of　DO,　ORP,　pH　to　build　a　fuzzy　control　system　was　studied.　The　above-mentioned　research　provides　theories　of　the　design　of　the　SBR　process　and　its　automation　control.
