A kind of water surface dirt collection filter device,It includes: a threeway tube body,One water surface guide seat and a filter element,The threeway tube body has the axial water intake end communicated and water outlet,And vertically to the water conservancy diversion end of connection,The water intake end is equipped with a connection sleeve,And the connection sleeve has a necking section,When water flow being enabled to be discharged via threeway tube body,So that water discharge speed is promoted through necking section,And then an attraction is generated,Oxygen can not only be brought into the oxygen content for promoting pond using appendix,On the other hand it can also be generated through the diversion pipe what water surface and attract effect,The water flow of the water surface is enabled to be able to be sucked by water surface guide seat,And then again through filter element carry out water surface drift dirt collection,Filtering,Prevent water quality by drift contamination and deterioration,The cleannes of water quality are kept,Increase the survival rate and the output value of organism in water.一種水面集污過濾裝置，其包含：一三通管體、一水面導引座以及一過濾單元，該三通管體具有軸向相通之入水端以及出水端，以及垂直向連通之導流端，該入水端設有一連接套筒，且該連接套筒具有一縮口段，令水流經由三通管體排出時，俾能透過縮口段提升出水流速，進而產生一吸引力，不僅能利用輸氣管將氧氣帶入提升水池之含氧量，另一方面還能透過導流管於水面產生吸引效果，令水面的水流得以由水面導引座吸入，進而再透過過濾單元進行水面漂流物的集污、過濾，防止水質受到漂流物污染變質，保持水質的清潔度，增添水中生物之存活率及產值。
