摘要：

In　order　to　supervise　the　programming　construction　and　the　operating　management　of　a　municipal　wastewater　treatment　plant　(WWTP),　the　fuzzy　matter-element　model　based　on　entropy　weight　of　an　index　was　used　as　the　evaluation　method　to　achieve　the　comprehensive　evaluation　and　analysis　on　operation　effect　and　its　influencing　factors　of　8　WWTPs　located　in　a　city　of　North　China.　The　primary　characteristic　of　the　method　was　that　the　weight　value　of　an　evaluation　index　could　be　objectively　assigned　and　calculated　based　on　actual　operational　data　of　a　WWTP,　avoiding　subjective　interferences　and　the　experience　restriction　of　a　researcher.　The　evaluation　result　could　reflect　operation　circumstances　of　a　WWTP　practically　and　objectively.　The　results　showed　that　the　operation　effect　of　WWTP　with　A/A/O　process　was　generally　good,　especially　the　removal　efficiencies　of　nitrogen　and　phosphorus　were　better　than　other　processes.　TN　removal　rate　and　the　productive　quantity　of　the　excess　sludge　cake　were　identified　as　important　factors　influenced　the　operation　effect.　So　the　operation　level　of　WWTP　could　be　approached　mainly　by　increasing　the　TN　removal　rate　and　decreasing　the　excess　sludge　cake　quantity.
